Differences in prevalence of self-reported oral hypofunction between older adult patients with rheumatoid arthritis and the general older population: A cross-sectional study using propensity score matching. J Oral Rehabil 2024; 51:924-930. [PMID: 38356183 DOI: 10.1111/joor.13658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 12/14/2023] [Accepted: 02/05/2024] [Indexed: 02/16/2024]
Abstract
OBJECTIVE To examine the association between rheumatoid arthritis (RA) and oral hypofunction (OHF) using propensity score matching (PSM) to adjust for differences between older adults with RA and the general older adult population. METHODS We conducted a cross-sectional survey among 189 older adults with RA in 2019 (mean age, 71.9 ± 3.6) and 47 178 independent older adult residents in 2016 (mean age, 71.6 ± 4.0), respectively. The questionnaire covered information on socio-demographic characteristics and OHF for both groups. Age, sex, educational level and smoking history were used to determine PSM. Prevalence ratios (PRs) and 95% confidence intervals (CIs) of self-reported OHF (fewer remaining teeth, decreased masticatory function, deterioration of swallowing function and oral dryness) were estimated using Poisson regressions. RESULT OHF was observed in 44.4% of patients with RA and 27.5% of residents. Before PSM, the prevalence of OHF among patients with RA was higher than that of residents (PR, 1.75; 95% CI, 1.50-2.05). After PSM, there were 189 patients with RA and residents, and the prevalence of OHF among patients with RA was still higher (PR, 1.61; 95% CI, 1.22-2.13). Poisson regression showed that the prevalence of 19 or fewer teeth (PR, 1.06; 95% CI, 0.82-1.36), difficulties eating tough foods (PR, 1.18; 95% CI, 0.90-1.55), difficulties swallowing tea or soup (PR, 1.77; 95% CI, 1.19-2.63), and dry mouth (PR, 2.79; 95% CI, 1.90-4.07) was higher among patients with RA than residents. CONCLUSION Compared with the general older adult population, patients with RA have a higher prevalence of self-reported OHF.

Abstract
ABSTRACT Sjögren syndrome (SS) is a chronic inflammatory autoimmune disease characterized by destruction of mucosal glands resulting in dry eye and dry mouth. Ocular presentations can be heterogenous in SS with corneal nerves abnormalities that are structural, functional, or both. Some individuals present with corneal hyposensitivity, with a phenotype of decreased tear production and epithelial disruption. Others present with corneal hypersensitivity, with a phenotype of neuropathic pain including light sensitivity and pain out of proportion to signs of tear dysfunction. A similar correlate can be found outside the eye, with dry mouth predominating in some individuals while pain conditions predominate in others. Understanding how nerve status affects SS phenotype is an important first step to improving disease management by targeting nerve abnormalities, as well as inflammation.

Integrated therapy of intraductal irrigations and sialoendoscopies of salivary glands to improve mouth dryness. Oral Dis 2024; 30:1198-1208. [PMID: 36630587 DOI: 10.1111/odi.14501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 10/22/2022] [Accepted: 12/20/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To assess the combination of salivary gland intraductal irrigations (IG) followed by sialoendoscopy irrigations (SI) of the parotid gland on the improvement of salivary gland secretory dysfunction (SGSD). METHODS We retrospectively analyzed the records of SGSD patients who underwent major salivary gland IG followed by SI during 2014-2020. Records included demographics, systemic background, signs, and symptoms. Improvement was assessed by comparing the mean unstimulated and stimulated whole salivary flow rate (UWSF, SWSF) from the baseline point (before IG procedure) to the last point (after SI) using repeated measures. The between-subjects effects of various factors and covariants were analyzed using repeated measures ANCOVA. RESULTS One hundred patients were included with an age range of 15-83 years (mean age of 60.1 ± 13.1 years). Improvement was detected on UWSF measurements (p = 0.031, F = 3.83), but not on SWSF measurements (p = 0.165, F = 1.85). The between-subjects effects on UWSF measurements were statistically significant for sex (p = 0.003, F = 9.526) and salivary gland manipulators use (p < 0.001, F = 15.107) and for the interaction between sex and salivary gland manipulators use (p- = 0.002, F = 9.709). Results of long-term follow-up for 10.87 ± 11.79 months after the SI procedure demonstrated sustained improvement in UWSF measurements (p = 0.011, F = 4.91). CONCLUSIONS The combination of IG followed by SI increases UWSF salivary secretion in SGSD patients for a relatively extended duration.

Abstract
OBJECTIVE To evaluate the effectiveness of topical sialogogue spray containing 1% malic acid in the treatment of xerostomia in patients with type 2 diabetes mellitus. MATERIAL AND METHODS A randomized double-blind controlled clinical trial was conducted on 52 patients with type 2 diabetes mellitus suffering from xerostomia. Patients were assigned equally to test group who received a topical sialogogue spray containing 1% malic acid and control group who received a placebo spray. Both groups were instructed to use the spray on demand for 2 weeks. The Summated Xerostomia Inventory-Dutch Version questionnaire (SXI-D) and the unstimulated salivary flow rate were evaluated for all patients at baseline, 2 and 4 weeks after malic acid/placebo application. RESULTS At 2 week's follow-up, the unstimulated salivary flow rate increased significantly from 0.059 ± 0.024 to 0.191 ± 0.064 and from 0.055 ± 0.026 to 0.078 ± 0.032 for test and control groups, respectively, with a statistically significant difference favoring the test group. SXI-D scores showed a significant decrease from 10.73 ± 2.22 to 8.38 ± 2.28 in the test group (p < 0.05), while in the control group it decreased from 10.62 ± 1.75 to 10.23 ± 1.48 (p > 0.05). CONCLUSION A sialogogue spray containing 1% malic acid increased the unstimulated salivary flow rate in patients with type 2 diabetes mellitus suffering from xerostomia.

Abstract
OBJECTIVE To assess the construct validity of the novel Outcome Measures in Rheumatology (OMERACT) ultrasound (US) semiquantitative scoring system for morphological lesions in major salivary glands by comparing it with magnetic resonance imaging (MRI) and unstimulated whole salivary flow rates (U-WSFRs) in patients with primary Sjögren syndrome (pSS). METHODS Nine sonographers applied the OMERACT 0-3 grayscale scoring system for parotid (PGs) and submandibular glands (SMGs) in 11 patients with pSS who also had MRIs performed. These were evaluated by 2 radiologists using a semiquantitative 0-3 scoring system for morphological lesions. The agreement between US and MRI and the association between U-WSFRs and imaging structural lesions was determined. A score ≥ 2 for both US and MRI was defined as gland pathology. RESULTS The prevalence of US morphological lesions in 11 patients with a score ≥ 2 was 58% for PGs and 76% for SMGs, and 46% and 41% for PGs and SMGs, respectively, for MRI. The agreement between OMERACT US scores and MRI scores was 73-91% (median 82%) in the right PG and 73-91% (median 91%) in the left PG, 55-91% (median 55%) in the right SMG and 55-82% (median 55%) in the left SMG. When relations between the presence of hyposalivation and an US score ≥ 2 were examined, agreement was 91-100% (median 83%) in both PGs and 55-91% (median 67%) in both SMGs. CONCLUSION There is moderate to strong agreement between the OMERACT US and MRI scores for major salivary glands in patients with pSS. Similar agreement ratios were observed between the higher OMERACT US scores and presence of hyposalivation.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are FDA-approved for various cancers, yet their orofacial immune-related adverse events (irAEs) remain poorly understood. Our two-center retrospective study aims to better understand the prevalence and nature of these orofacial irAEs. METHODS We retrospectively collected demographics, ICI details, and onset of orofacial irAEs in ICI-treated patients at University of California San Francisco and City of Hope (2013-2021). Orofacial irAEs were identified by ICD-10 codes and data categorized as dry mouth/xerostomia, oral mucosal lesions, and orofacial neuropathies. Patients with pre-existing orofacial conditions resembling the reported irAEs were excluded. RESULTS Among 3768 ICI-treated patients, 408 (10.8%) developed 467 orofacial irAEs: oral mucosal diseases (41.4%), dry mouth/xerostomia (41.0%), and orofacial neuropathies (17.6%). Notably, head and neck cancers had the highest incidence of orofacial irAEs. CONCLUSIONS Orofacial irAEs are relatively common in patients receiving ICIs, necessitating careful monitoring and management of these complications during and after the treatment.

Abstract
INTRODUCTION The symptom of dry mouth has multiple potential etiologies and can be a diagnostic clue to the presence of common systemic diseases encountered in rheumatology practice. The presence of decreased saliva flow (i.e. salivary hypofunction) defines a subset of dry mouth patients in whom there may be reversible drug effects, an iatrogenic insult such as head and neck irradiation, or a disease that directly involves the salivary glands (e.g. Sjögren's disease). The assessment of salivary hypofunction includes sialometry, salivary gland imaging, salivary gland biopsy, and an assessment for relevant systemic diseases. Optimal management of dry mouth requires accurate definition of its cause, followed by general measures that serve to alleviate its symptoms and prevent its complications. AREAS COVERED Through a literature search on xerostomia and salivary hypofunction, we provide an overview of the causes of dry mouth, highlight the potential impact of salivary hypofunction on oral and systemic health, detail routine evaluation methods and treatment strategies, and emphasize the importance of collaboration with oral health care providers. EXPERT OPINION Our Expert Opinion is provided on unmet needs in the management of dry mouth and relevant research progress in the field.

Abstract
OBJECTIVES Morning dry mouth, commonly seen in Obstructive Sleep Apnea (OSA) patients, is absent in current OSA screening tools. This study evaluated the link between morning dry mouth and OSA's clinical symptoms and complications, aiming to determine its viability as a screening indicator. METHODS This research analyses baseline data from a prospective cohort study (the PIFCOPD study). Demographic information, medical history, and the presence of morning dry mouth symptoms were collected. The STOP-Bang questionnaire was performed for OSA screening. Logistic regression analyses were employed to establish the correlations between morning dry mouth and the clinical symptoms and comorbidities of OSA. RESULT 1291 participants (62.1±7.5 years; 501 males, 790 females) were included, of which 416 reported morning dry mouth (32.2%). 42.6% in the high-risk OSA group and 22.1% in the low-risk group reported morning dry mouth. Individuals with morning dry mouth also showed higher STOP-Bang scores (3.3±1.6 vs. 2.3±1.4, P<0.01). Significant associations were found between morning dry mouth and loud snoring, observed sleep apnea, daytime fatigue, and hyperlipidemia (P<0.01), but not with alcohol consumption, tea consumption, diabetes, or hypertension. CONCLUSION Morning dry mouth is associated with increased OSA risk and its clinical signs, suggesting its potential as an OSA screening symptom. CLINICAL TRIAL REGISTRATION This study has been registered at www.ClinicalTrials.gov (registration identifier: NCT03532893) on 21 May 2018.

Abstract
OBJECTIVES Radiation-induced dry mouth negatively impacts patients' oral health and quality of life. Currently, evidence-based recommendation for non-pharmacologic interventions is still lacking. This study aimed to systematically review clinical trials evaluating the efficacy of non-pharmacologic interventions in cancer patients with radiation-induced dry mouth. METHODS Randomized controlled trials from 2000 were searched from 4 databases, including MEDLINE, Cochrane, Embase via OVID, and SCOPUS, up to December 16th, 2022 (PROSPERO registration CRD42022378405). The risk of bias was assessed using the revised Cochrane risk of bias assessment tool. RESULTS Twenty-one studies were included: 11 on artificial saliva, 4 on electrical nerve stimulation (TENS), 2 on acupuncture, and one study each on low-level laser therapy, stem cells, chewing gum, and probiotics. Overall bias was low, medium, and high in 33%, 48%, and 19% of the studies, respectively. Certain artificial saliva products and TENS were shown to improve dry mouth symptoms and salivary flow rate (SFR). One study showed that stem cell transplantation significantly increased SFR. CONCLUSIONS The evidence suggested that certain artificial saliva products and TENS are promising management. However, the evidence was still limited due to heterogeneity of interventions and outcome measurements. Thus, future studies using standard measurements and long-term follow-up are warranted.

Abstract
The sensation of thirstiness is the desire to drink water. In certain situations, the ingestion of liquid water can be restricted. As a result, thirstiness is not relieved, resulting in an uncomfortable and distressing situation. The present review describes thirstiness and hydration, the food products and beverages that cause thirstiness, and the beverages and food products currently available to quench thirstiness in individuals with restricted access to liquid ingestion. It also discusses how to measure the effectiveness of calming thirstiness. To diminish thirstiness distress, different alternatives to liquids are proposed. Individuals with swallowing disorders are given thickened water, individuals with restricted water ingestion are given ice cubes or ice popsicles of different flavors, and sportspeople are given energy gels. However, current beverage solutions seem not to relieve thirst fully, although some stimuli like iced water, flavors (especially lemon and mint), or acids seem to work better than plain stimuli and could be added to existing products. Therefore, there is still a need to incorporate these strategies into beverage and food formulations and to test their effectiveness.

Abstract
OBJECTIVE We aim to assess the validity and reliability of the Arabic language translation of the Summated Xerostomia Inventory (SXI). METHODS A cross-sectional, self-administered, electronic Arabic SXI was sent to 79 patients with thyroid nodules (female: n = 34, 57%; male: n = 45, 57%) who visited the Otolaryngology-Head and Neck Surgery clinic at King Abdulaziz University Hospital and King Fahad Medical City between June 2023 and July 2023. RESULTS Dependability was assessed using Cronbach's alpha coefficients at two distinct instances (first: α = 0.824, second: α = 0.932), which reaffirmed the SXI's reliability and consistency. Legitimacy was ascertained using a test-retest method and correlation analysis between the two measurements. CONCLUSION All SXI items displayed a potent positive correlation (between 0.746 and 0.871, p < 0.001), exhibiting remarkable consistency in responses over time. The outcomes of the paired t-tests showed nonsignificant differences for all queries, indicating that the responses were stable over time.

Abstract
OBJECTIVE Xerostomia (or oral dryness) is most commonly caused by medications that affect saliva secretion, and is often accompanied by symptoms of orofacial pain. Medication-induced xerostomia may or may not be associated with objectively demonstrable hyposalivation. The present study attempted to systematically identify an association between medication-induced xerostomia and orofacial pain. METHOD AND MATERIALS A systematic search was conducted using the following databases: WoS, PubMed, SCOPUS, and MEDLINE. The search terms used were: xerostomia OR "dry mouth" AND medication AND ("oral pain" OR "orofacial pain" OR "craniofacial pain" OR "burning mouth" OR "glossodynia") NOT Sjögren's NOT cancer. Inclusion criteria were medication-induced xerostomia and reported symptoms of orofacial pain. Four researchers performed the selection process and quality assessment and two researchers conducted data extraction. RESULTS Seven studies with a total of 1,029 patients were included. These studies were conducted between 2009 and 2022 and consisted of cross-sectional studies, case-control studies, and one randomized crossover trial. The studies consisted of a total of 1,029 participants. All studies included male and female participants whose mean ages ranged from 43 to 100 years. CONCLUSIONS A positive association was found between medication-induced xerostomia and orofacial pain. No associations were found between salivary flow measurements (hyposalivation) and medication use. Future research should focus on saliva flow measurements, standardized assessment of medication-induced xerostomia, as well as the inclusion of accompanying orofacial pain diagnosis in the medical history to allow for higher level of evidence in establishing reliable predictors of medication-induced oral health damage to facilitate clinical prevention and management.

Abstract
BACKGROUND Sjögren syndrome is a systemic autoimmune disease characterized by lacrimal and salivary gland inflammation resulting in dry eyes and mouth. Although it is a common disease, diagnosis can be challenging due to its heterogeneous presentation. A positive minor salivary gland biopsy is mandatory to fulfill the 2016 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for primary Sjögren syndrome in patients who are seronegative for anti-SSA/Ro antibodies. The objective of our study was to evaluate the validity of minor salivary gland biopsy for patients who are SSA antibody-negative yet are suspected of having primary Sjögren syndrome because of compelling symptoms. METHODS We conducted a retrospective chart review of adult patients with a negative anti-SSA antibody test who underwent minor salivary gland biopsy to assess suspected Sjögren syndrome at Henry Ford Rheumatology Clinics between January 2005 and December 2019. Patient characteristics and clinical features are described. Sensitivity, specificity, positive predictive value, and negative predictive value are assessed. RESULTS A total of 47 patients were included: 46 (97.9%) females and one (2.1%) male. The mean age was 57.2 ± 13.8 years. There were 14 (29.8%) patients who had a positive minor salivary gland biopsy result and 15 (31.9%) patients who had a final diagnosis of Sjögren syndrome. Minor salivary gland biopsy had 93.3% sensitivity (95% confidence interval (CI): 68%-99.8%), 100% specificity (95% CI: 89.1%-100%), 100% positive predictive value (95% CI: 76.8%-100%), and 97% negative predictive value (95% CI: 84.2%-99.9%). CONCLUSION The diagnostic value of minor salivary gland biopsy is high for patients who do not have anti-SSA antibodies yet are suspected of having Sjögren syndrome. The results of the study support the consideration of routine minor salivary gland biopsy for identifying Sjögren syndrome in these patients.

Abstract
Xerostomia, commonly known as dry mouth, is a widespread oral health malfunction characterized by decreased salivary flow. This condition results in discomfort, impaired speech and mastication, dysphagia, heightened susceptibility to oral infections, and ultimately, a diminished oral health-related quality of life. The etiology of xerostomia is multifaceted, with primary causes encompassing the use of xerostomic medications, radiation therapy to the head and neck, and systemic diseases such as Sjögren's syndrome. Consequently, there is a growing interest in devising management strategies to address this oral health issue, which presents significant challenges due to the intricate nature of saliva. Historically, natural products have served medicinal purposes, and in contemporary pharmaceutical research and development, they continue to play a crucial role, including the treatment of xerostomia. In this context, the present review aims to provide an overview of the current state of knowledge regarding natural compounds and extracts for xerostomia treatment, paving the way for developing novel therapeutic strategies for this common oral health issue.

Abstract
BACKGROUND Xerostomia can pose significant problems for many elderly people. OBJECTIVES To investigate longitudinal changes in prevalence, persistence, progression, remission, and incidence of xerostomia from age 75 to 85 years. METHODS All 75-year-olds (born 1932) from two Swedish counties, Sweden were mailed a questionnaire in 2007 (N = 5195), and again in 2017 when they were aged 85 (N = 3323). The total response rates at ages 75 and 85 years were 71.9% and 60.8%, respectively. A "panel", those who participated in both surveys, comprised 1701 individuals (response rate 51.2%). RESULTS At age 85, there was almost a doubling of self-reported "yes often" xerostomia compared with age 75 (from 6.2% to 11.3%) and was almost twice as common in women than men (p<0.001). When combining "yes often"/"yes sometimes", xerostomia increased from 33.4% to 49.0%, and was more so among women (p<0.001). Xerostomia was commoner at night than daytime, with 23.4% reporting "yes often" night-time xerostomia at 85 compared with 18.5% at 75, and was also higher in women (p<0.001). Progression rates for daytime and night-time xerostomia were 34.2% and 38.1%, for persistence 67.4% and 68.6%, and for remission 24.4% and 16.5%. Average yearly incidence was higher in women than men for both daytime (3.6% vs. 3.2%) and night-time (3.9% vs. 3.7%). Regression analyses predicted protective factors for developing xerostomia reported at age 75 as good general and oral health, absence of medications/intraoral symptom/s, good chewing function and social interaction. CONCLUSIONS Xerostomia increases markedly from age 75 to 85 years.

Xerostomia: From Pharmacological Treatments to Traditional Medicine-An Overview on the Possible Clinical Management and Prevention Using Systemic Approaches. Curr Oncol 2023; 30:4412-4426. [PMID: 37232794 DOI: 10.3390/curroncol30050336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 04/16/2023] [Accepted: 04/22/2023] [Indexed: 05/27/2023] Open
Abstract
Despite high incidence rates and severe complications, the management of xerostomia lacks clinical guidelines. The aim of this overview was to summarize the clinical experience derived from the last 10 years of treatments and prevention using systemic compounds. Results showed that the cytoprotective drug amifostine, and its antioxidant agents, are the most discussed as preventive agents of xerostomia in head and neck cancer (HNC) patients. In the presence of the disease, the pharmacological treatments have been mainly directed to stimulate secretion of the damaged salivary glands, or to counteract a decreased capacity of the antioxidant system, in view of an increasing of reactive oxygen species (ROS). However, the data demonstrated low ability of the drugs, together with a great number of side effects, which strongly limit their use. Concerning traditional medicine (TM), valid clinical trials are so limited that neither the efficacy nor the absence of interferences to concomitant chemical therapies can be validated. Consequently, the management of xerostomia and its devastating complications remain a very significant void in daily clinical practice.

The Relationship of Oral Health with Progression of Physical Frailty among Older Adults: A Longitudinal Study Composed of Two Cohorts of Older Adults from the United Kingdom and United States. J Am Med Dir Assoc 2023; 24:468-474.e3. [PMID: 36584971 PMCID: PMC10398566 DOI: 10.1016/j.jamda.2022.11.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 11/24/2022] [Accepted: 11/29/2022] [Indexed: 12/29/2022]
Abstract
OBJECTIVE To investigate the prospective associations between oral health and progression of physical frailty in older adults. DESIGN Prospective analysis. SETTING AND PARTICIPANTS Data are from the British Regional Heart Study (BRHS) comprising 2137 men aged 71 to 92 years from 24 British towns and the Health, Aging, and Body Composition (HABC) Study of 3075 men and women aged 70 to 79 years. METHODS Oral health markers included denture use, tooth count, periodontal disease, self-rated oral health, dry mouth, and perceived difficulty eating. Physical frailty progression after ∼8 years follow-up was determined based on 2 scoring tools: the Fried frailty phenotype (for physical frailty) and the Gill index (for severe frailty). Logistic regression models were conducted to examine the associations between oral health markers and progression to frailty and severe frailty, adjusted for sociodemographic, behavioral, and health-related factors. RESULTS After full adjustment, progression to frailty was associated with dentition [per each additional tooth, odds ratio (OR) 0.97; 95% CI: 0.95-1.00], <21 teeth with (OR 1.74; 95% CI: 1.02-2.96) or without denture use (OR 2.45; 95% CI 1.15-5.21), and symptoms of dry mouth (OR ≥1.8; 95% CI ≥ 1.06-3.10) in the BRHS cohort. In the HABC Study, progression to frailty was associated with dry mouth (OR 2.62; 95% CI 1.05-6.55), self-reported difficulty eating (OR 2.12; 95% CI 1.28-3.50) and ≥2 cumulative oral health problems (OR 2.29; 95% CI 1.17-4.50). Progression to severe frailty was associated with edentulism (OR 4.44; 95% CI 1.39-14.15) and <21 teeth without dentures after full adjustment. CONCLUSIONS AND IMPLICATIONS These findings indicate that oral health problems, particularly tooth loss and dry mouth, in older adults are associated with progression to frailty in later life. Additional research is needed to determine if interventions aimed at maintaining (or improving) oral health can contribute to reducing the risk, and worsening, of physical frailty in older adults.

The association between dental arch length and oral health-related quality of life in head and neck cancer patients post-radiotherapy. SPECIAL CARE IN DENTISTRY 2023; 43:111-118. [PMID: 35830628 DOI: 10.1111/scd.12755] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 04/13/2022] [Accepted: 06/27/2022] [Indexed: 12/27/2022]
Abstract
AIMS To assess the association between length of dental arch and oral health-related quality of life in head and neck cancer patients post-radiotherapy. METHODS Thirty head and neck cancer participants reported their oral health-related quality of life using the oral health impact profile-14 instrument and their global self-rating of general and oral health. All patients had received chemotherapy and radiotherapy. The length of dental arch was assessed in three tooth relational categories: canine-to-canine, shortened (premolars to premolars), and long (molars to molars) dental arches. Inclusion of participants for any of the three categories required verification of opposing teeth relationship with Shim Stock paper. RESULTS Out of 30 head and neck cancer patients, eight (27%) had a canine-to-canine dental arch, 14 (46%) had a shortened dental arch, and eight (27%) had a long dental arch. The median oral health impact profile-14 scores for participants respectively with the canine-to-canine dental arch was six (IQR = 9.25), seven (IQR = 8) for participants with shortened dental arch, and 11 (IQR = 12.5) for participants with long dental arch. There were no significant differences in oral health impact profile-14 scores between the three-tooth relational groups (Kruskal-Wallis H = 0.769, df = 2, P-value = .681). Similarly, there were no significant differences between three-tooth relational groups on the self rating of general (Chi-squared = 1.714, df = 2, P-value = .424) and oral health (Chi-squared = 1.393, df = 2, P-value = .498). CONCLUSION Within the limitations of this study, no association was found between the length of dental arch and oral health-related quality of life in head and neck cancer patients post-radiotherapy. Other factors such as dry mouth, oral mucositis, loss of taste, and trismus should be considered as contributory factors to reduced oral health-related quality of life in head and neck cancer patients post-radiotherapy, particularly in relation to eating difficulties.

Abstract
OBJECTIVES Xerostomia, or dry mouth, is a condition that results from the reduction or absence of saliva flow secondary to the use of certain medications. The objective of the present study was to analyze the relationship between xerostomia patients and the consumption of serotonin norepinephrine reuptake inhibitors (SNRIs). METHOD AND MATERIALS The University of Florida (UF) Integrated Data (IDR) i2b2, for the period of June 2015 to September 2022, was used based on aggregates of the International Classification of Diseases 10th edition (ICD-10) diagnoses of dry mouth and use of SNRI. MedCalc Software was used to calculate odds ratios. RESULTS The odds ratio for dry mouth in the SNRI group was 5.95 (95% CI 5.47 to 6.48, P < .0001). The odds ratio for dry mouth in females on SNRI was 5.48 (95% CI 4.97 to 6.02, P < .0001), for males 5.48 (95% CI 4.56 to 6.95), P < .0001), for children 2.87 (95% CI 1.19 to 6.96, P = .0192), and for adults 4.46 (95% CI 4.09 to 4.86, P < .0001). When the different SNRIs were analyzed separately, the odds ratio for dry mouth with the use of venlafaxine was 5.83 (95% CI 5.12 to 6.6, P < .0001), duloxetine 6.97 (95% CI 6.33 to 7.67, P <.0001), desvenlafaxine 5.24 (95% CI 3.65 to 7.52, P < .0001), and milnacipran 9.61 (95% CI 5.66 to 16.31, P < .0001). CONCLUSION According to the present study, patients who are taking SNRIs are five-fold more likely to develop dry mouth compared to those not on medications. The results could be informative to medical professionals who prescribe SNRIs and who are not currently aware of the effect they have on salivary production and therefore quality of life, as well as the dental practitioners treating these patients with dry mouth sequalae.

Abstract
OBJECTIVE The aim was to study the association between high anticholinergic burden and hyposalivation and xerostomia among older people. BACKGROUND Anticholinergic drugs have been shown to cause xerostomia and hyposalivation. Yet there are few studies on the association between anticholinergic burden and hyposalivation and xerostomia in the elderly. MATERIAL AND METHODS The study population consisted of community-dwelling older people (n = 321, mean age 81.6 years) from the Oral health GeMS study. Participants provided salivary samples and xerostomia was determined with a questionnaire. The baseline data were collected by interviews, oral clinical examinations and from patient records. Each participant's anticholinergic burden was determined by eight anticholinergic scales. Poisson regression models with robust error variance were used to estimate relative risks (RR) with a 95% confidence interval (CI). RESULTS RRs of high anticholinergic burden in anticholinergic scales for xerostomia (multiple symptoms) ranged from 1.02 to 1.68; for low unstimulated salivary flow (≤0.1 mL/min) from 1.47 to 1.67; and for low stimulated salivary flow (≤0.7 mL/min) from 0.99 to 2.07. A high anticholinergic burden according to seven out of eight scales was associated (p < .05) with hyposalivation or xerostomia. CONCLUSIONS A high anticholinergic burden was associated more strongly with hyposalivation (both unstimulated and stimulated) than with xerostomia.

Abstract
AIMS To investigate the efficacy of applying auricular acupuncture (AA) treatment in improving dry mouth in institution-dwelling older adults. BACKGROUND Dry mouth (xerostomia) is a common distressing problem in older populations, especially for institution-dwelling older adults that can affect oral health and quality of life. DESIGN A randomised controlled trial was conducted from December 2020 to March 2021 and performed according to STRICTA guidelines extended from the CONSORT statement. METHODS Older adults aged more than 65 years were randomly allocated to an AA group (n = 37) with an 8-week actual auricular points treatment or a control group (n = 38) receiving sham auricular point acupuncture. Measurements comprised a subjective assessment of the level of dry mouth as assessed by a visual analogue scale in a xerostomia questionnaire, and an objective assessment of the physiological wetness of the lingual mucosa measured with a moisture-checking device. A generalised estimating equation model was used for data analyses. RESULTS After completing an 8-week AA intervention stimulating the Shenmen, Point Zero and Salivary Gland 2-prime points, the AA group exhibited significantly improved subjective symptoms of dry mouth comprised of difficulty speaking (B = -6.47, p < .001), difficulty swallowing (B = -6.73, p < .001), the amount of oral saliva (B = -5.38, p < .001), a dry throat (B = -7.53, p < .001) and thirst (B = -8.06, p < .001) compared with the control group. Moreover, the AA group had higher objective oral saliva flow than the control group (B = 4.73, p < .001). CONCLUSION AA is an effective non-pharmacological method for improving subjective symptoms of dry mouth and objective saliva secretion in older populations living in nursing homes. RELEVANT TO CLINICAL PRACTICE Performing regular AA on the Shenmen, Point Zero and Salivary Gland 2-prime auricular points can be considered an alternative treatment approach to improve dry mouth in institution-dwelling older adults.

Abstract
BACKGROUND Face masking is associated with self-perceived dry mouth and halitosis. Aim of the study was to measure the effect of different face masks on salivary parameters and halitosis. METHODS The randomized controlled crossover clinical trial with four periods included 40 oral healthy participants using different face masks (cloth mask, surgical mask, filtering facepiece 2 [FFP2] mask) or no mask (control) for 4 h in random order. Unstimulated salivary flow rate (primary outcome) and stimulated salivary flow rate, salivary pH and buffer capacity of stimulated and unstimulated saliva (secondary outcomes, blinded), and volatile sulfur compounds (secondary outcome) were measured before and after the 4-h periods. Statistical analysis was performed by repeated measures ANOVA (p < 0.05). RESULTS Of 40 randomized participants, 39 completed the study. Unstimulated salivary flow rate prior to face masking amounted to 0.6 ± 0.3 ml/min. Face masking had no significant effect on unstimulated salivary flow (p = 0.550). Face masking had also no significant effect on the other salivary parameters (p ≥ 0.518). The concentration of volatile sulfur compounds (VSC) prior to face masking amounted to 157.3 ± 59.7 ppb. After face masking, the concentration of VSC increased slightly, but not significantly (p = 0.055): 168.1 ± 76.3 ppb (control), 199.3 ± 132.7 ppb (cloth masks), 188.5 ± 101.1 ppb (surgical masks), and 189.7 ± 90.1 ppb (FFP2 masks). CONCLUSION Four hours of face masking did not change the salivary flow rate, pH, and buffer capacity, and had no significant effect on VSC's levels. Wearing face masks does not seem to result in measurable side-effects on salivary parameters such as a reduced salivary flow rate or VSC's levels. CLINICAL TRIAL REGISTRATION The protocol was prospectively registered at ClinicalTrials.gov (NCT04914208) on June 4, 2021.

Oral and Mucosal Complaints among Institutionalized Care Seniors in Malopolska Voivodeship-The Utility of the Mirror Sliding Test in an Assessment of Dry Mouth. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph192113776. [PMID: 36360656 PMCID: PMC9657787 DOI: 10.3390/ijerph192113776] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 10/20/2022] [Accepted: 10/21/2022] [Indexed: 05/13/2023]
Abstract
The purpose of this article was to evaluate reported oral and mucosal complaints among seniors residing in institutionalized 24-h care of the Municipal Center for Older and Dependent People (MHCOD) and the 3-month rehabilitation program of the Daily Medical Care House (DMCH). We evaluated the feasibility of using the dental mirror slidding test to assess dry mouth of seniors. Patients underwent a questionnaire, and clinical examination. The Visual Analogue Scale (VAS) was used to assess pain, Fox's questionnaire and Challacombe's scale with Clinical Oral Dryness Score to assess dryness of the mouth, dental mirror slidding test to assess buccal mucosal resistance. Dryness, mucosal burning, impaired taste, food intake are symptoms associated with seniors, and their frequency does not depend on the type of care. The incidence of mucosal burning (Mdn = 4.0, IQR = 4.75, p = 0.032) and difficulty in using dental prosthetics (Mdn = 3.0, IQR = 4.00, p = 0.010) increase with the length of stay at MHCOD. Seniors are at risk of side effects of polypharmacy, which cause dryness (p = 0.036), complaints of lack of saliva (p = 0.009) and taste disorders (p = 0.041. Seniors with higher levels of dry mouth are more likely to exhibit mucosal burning (p = 0.026) and difficulty in taking food (p = 0.037). The implementation of the dental mirror slidding test in the scope of the primary care of geriatric examination should be discussed.

Abstract
Demographic ageing is a global growing process and the quality of ageing is an important parameter in this process. The aim of the study was to analyse the distribution of remaining dentition in relation to oral hygiene indicators among elderly people remaining in institutional care and those who participated in a 3-month rehabilitation program, aimed at increasing time of independent functioning, in southern Poland. The patients underwent a questionnaire and clinical examination. An analysis of missing teeth was performed, plaque index, and gingival index were measured. Residents of the Municipal Health Centre for Older and Dependent People (n = 50) had a higher incidence of missing teeth in the maxilla (88.4%), mandible (77.6%), as well as in the maxilla and mandible combined (83%) than residents of the Daily Medical Care House (n = 30). The distribution of the remaining teeth, in both groups, corresponds to the outlets of the large salivary glands. The group of 53.8% of patients with dry mouth had PI scored 3. Residents with dry mouth were more likely to have plaque deposits and gingival inflammation. It is necessary to develop and implement an oral care program for patients with reduced saliva secretion, with a particular focus on dependents.

Abstract
Most yeasts causing infections in humans are part of commensal microflora and etiological agents of different infections when hosts become susceptible, usually due to becoming immunocompromised. The colonization of potentially pathogenic microbes in the oral cavity is increased by poor oral hygiene. This follow-up survey was conducted approximately two months after providing information on proper oral care at 10 nursing homes in Taiwan. Among the 117 of 165 residents colonized by yeasts, 67 were colonized by more than one yeast species. A total of 231 isolates comprising eight fungal genera and 25 species were identified. Candida albicans (44.6%) was the dominant species, followed by Candida glabrata (17.7%), Candida parapsilosis (8.7%), Candida tropicalis (7.8%), and Candida pararugosa (7.3%). Residents having a yeast colony-forming unit >10 (OR, 8.897; 95% CI 2.972−26.634; p < 0.001) or using a wheelchair (OR, 4.682; 95% CI 1.599−13.705; p = 0.005) were more likely to be colonized by multiple species. By comparing before and after oral-care education, dry mouth (OR, 3.199; 95% CI 1.448−7.068; p = 0.011) and having heart disease (OR, 2.681; 95% CI 1.068−6.732; p = 0.036) emerged as two independent risk factors for increased density of colonizing yeast.

Abstract
OBJECTIVES To follow the same individuals from age 50 up to 75 years to report on prevalence, persistence, progression, remission, incidence and predictors for xerostomia. METHODS A questionnaire was distributed to all 50-years-olds (1992) in two Swedish counties (N=8888) and repeated at the age of 65 (2007) and 75 years (2017). 3060 individuals responded on all three occasions (response rate 42.5%). Xerostomia was assessed with two questions. Additional questions addressed inter alia general/oral health and oral function. RESULTS Reported prevalence of daytime xerostomia were 23.3% and 14.7%, and 39.5% and 27.5% in women and men, age 50 and 75, respectively. Night-time prevalence was higher. At age 50, 27.4% women and 24.0% men reported having dry mouth, and at age 75, 61.0% and 53.8%, respectively. At all time points, women reported significantly more xerostomia than men. Progression (deterioration) was common, and persistence (continuing presence) was high, while 25-year incidence for daytime xerostomia was 16.2% and 12.8%, and 33.6% and 29.8% at night-time, for women and men, respectively. Based on reports at age 50, regression analyses showed that prediction for developing xerostomia during the observation period, and reporting xerostomia at age 75 years, were female gender, impaired general health, chewing, jaw opening and intraoral problems, dissatisfaction with dental appearance, low education and having white/plastic filling. CONCLUSIONS Xerostomia is common in older people, especially at night and in women. It can be predicted by diverse factors reported earlier in life. CLINICAL SIGNIFICANCE Clinicians need to be made aware of that elderly often suffers from dry mouth so that they can recommend effective measures to eliminate or ease the patients accompanying symptoms and also exclude or lessen possible negative impact on oral health related to xerostomia.

Abstract
The importance of lubrication between oral surfaces provided by the salivary film is most acutely apparent when it is disrupted, a prevalent consequence of salivary gland hypofunction experienced with aging, a symptom of certain diseases, or a side effect of some medical interventions. Sufferers report difficulty with speech and oral food processing and collectively is detrimental to quality of life. Polyethylene glycol (PEG) is widely employed as a successful biocompatible boundary lubricant in engineering and biomedical applications. It is hypothesized that the immobilization of PEG to biological materials such as oral epithelial cells and tissue can mimic the salivary film and provide durable relief from the symptoms of mucosal dryness. To do so, PEG is functionalized with a sugar binding lectin (wheat germ agglutinin) to enhance epithelial adhesion through lectin-sugar interactions. Retention and lubricity are characterized on an ex vivo oral tissue tribology rig. WGA-PEG coats and retains on mucin films, oral epithelial cells, and porcine tongue tissue, and offers sustained reduction in coefficient of friction (COF). WGA-PEG could be developed into a useful topical treatment for reducing oral friction and the perception of dry mouth.

OBJECTIVES/HYPOTHESIS In this study, we assessed gustatory function and whole-mouth saliva in healthy adults and investigated the association between gustatory function, salivary flow rate (SFR), and dry mouth. STUDY DESIGN Descriptive clinical study. METHODS We recruited 413 participants who reported a normal sense of smell-taste, comprising 206 females and 207 males with an age range of 19 to 80 years. Taste scores were obtained using whole-mouth tests to evaluate the gustatory function, SFR was assessed using the spitting method, and dry mouth was measured with the visual analog scale. RESULTS The total taste score (TTS) and SFR were significantly negatively correlated with age (rtaste = -0.522, P < .001; rSFR = -0.200, P < .001): TTS was significantly lower after the age of 50 and SFR decreased significantly after age 65. Women exhibited a significantly higher TTS than men (P < .001). However, there was no effect of sex on SFR. Dry mouth was negatively correlated with TTS (r = -0.223, P < .01) and SFR (r = -0.218, P < .01). Multiple regression analysis showed the independent variables of age, sex, and dry mouth predicted 34% of the variation in taste, while the independent variables of age and dry mouth predicted 6.1% of the variation in whole-mouth saliva. TTS was not significantly correlated with the SFR in healthy adults (r = 0.094, P = .056). CONCLUSIONS Age and dry mouth are important factors affecting gustatory function and whole-mouth saliva, with women exhibiting better taste sensitivity than men. Furthermore, there is no direct correlation between SFR and gustatory function in healthy adults. LEVEL OF EVIDENCE 3 Laryngoscope, 2021.

Genome-Wide Association Study of Lithium-Induced Dry Mouth in Bipolar I Disorder. J Pers Med 2021; 11:jpm11121265. [PMID: 34945737 PMCID: PMC8706003 DOI: 10.3390/jpm11121265] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 11/26/2021] [Accepted: 11/27/2021] [Indexed: 11/17/2022] Open
Abstract
Dry mouth is a rather common unpleasant adverse drug reaction (ADR) to lithium treatment in bipolar disorders that often lead to poor adherence or early dropout. The aim of this study was to identify the genetic variants of dry mouth associated with lithium treatment in patients with bipolar I (BPI) disorder. In total, 1242 BPI patients who had ever received lithium treatment were identified by the Taiwan Bipolar Consortium for this study. The proportions of patients who experienced impaired drug compliance during lithium medication were comparable between those only with dry mouth and those with any other ADR (86% and 93%, respectively). Dry mouth appeared to be the most prevalent (47.3%) ADR induced by lithium treatment. From the study patients, 921 were included in a genome-wide association study (GWAS), and replication was conducted in the remaining 321 patients. The SNP rs10135918, located in the immunoglobulin heavy chain locus (IGH), showed the strongest associations in the GWAS (p = 2.12 × 10−37) and replication groups (p = 6.36 × 10−13) (dominant model) for dry mouth with a sensitivity of 84.9% in predicting dry mouth induced by lithium. Our results may be translated into clinical recommendation to help identify at-risk individuals for early identification and management of dry mouth, which will improve medication adherence.

A Clinical Study on the Efficacy and Tolerability of a New Topical Gel and Toothpaste in Patients with Xerostomia: A Randomized Controlled Trial. J Clin Med 2021; 10:jcm10235641. [PMID: 34884343 PMCID: PMC8658424 DOI: 10.3390/jcm10235641] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 11/22/2021] [Accepted: 11/26/2021] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE xerostomia is a very common problem in the general population. The objective of this study was to determine the efficacy of a new gel and toothpaste in patients with xerostomia, analyze the role of salivary cytokines as biomarkers of xerostomia and assess the possible changes in salivary cytokines following treatment. MATERIALS AND METHODS A randomized, controlled double-blind clinical study was carried out in 73 patients with xerostomia divided into two groups: placebo and active treatment (cymenol; tocopheryl acetate; D-panthenol; Aloe barbadensis; citrate tribasic dihydrate; fluoride) with oral gel and toothpaste three times a day for four consecutive weeks. The Thomson Xerostomia Inventory was applied, with the assessment of oral quality of life (OHIP-14) at baseline and after four weeks of application of the product. Sialometry was also performed in both groups, with analysis of the IL-1b, IL-6, IL-8 and TNFa levels in saliva. RESULTS In the active treatment group, the xerostomia scores decreased significantly at the end of the study versus baseline, from 33.47 to 27.93 (p < 0.001). No significant decrease was recorded in the placebo group (34.5 to 32.75; p = 0.190). There were no adverse effects in either group. Regarding the saliva samples, the active treatment group showed significant differences in IL-6 concentration versus the control group (18.55 pg/mL (8-38.28) and 5.83 pg/mL (1.19-12.04), respectively; p = 0.002). No significant differences in salivary cytokines were observed in either the treatment group or the control group. CONCLUSIONS The use of a new toothpaste and gel developed for patients with xerostomia proved effective, with greater symptom relief than in the placebo group. Further clinical studies involving longer time periods and larger samples are advisable in order to confirm the benefits of the described treatment.

Characterization and Pathogenic Speculation of Xerostomia Associated with COVID-19: A Narrative Review. Dent J (Basel) 2021; 9:dj9110130. [PMID: 34821594 PMCID: PMC8625834 DOI: 10.3390/dj9110130] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 11/06/2021] [Accepted: 11/08/2021] [Indexed: 12/23/2022] Open
Abstract
Patients with coronavirus disease 2019 (COVID-19) have become known to present with different oral symptoms. However, xerostomia remains poorly recognized compared with taste dysfunction. For better understanding of COVID-19 symptomatology, xerostomia associated withCOVID-19 was characterized and its possible pathogenesis was speculated by a narrative literature review. Scientific articles were retrieved by searching PubMed, LitCovid, ProQuest, Google Scholar, medRxiv and bioRxiv from 1 April 2020 with a cutoff date of 30 September 2021. Results of the literature search indicated that xerostomia is one of prevalent and persistent oral symptoms associated with COVID-19. In contrast to taste dysfunction, the prevalence and persistence of xerostomia do not necessarily depend on ethnicity, age, gender and disease severity of patients. COVID-19 xerostomia is pathogenically related to viral cellular entry-relevant protein expression, renin-angiotensin system disturbance, salivary gland inflammation, zinc deficiency, cranial neuropathy, intercurrent taste dysfunction, comorbidities and medications. Despite a close association with COVID-19, xerostomia, dry mouth and hyposalivation tend to be overlooked unlike ageusia, dysgeusia and hypogeusia. Although mouth dryness per se is not life-threating, it has an impact on the oral health-related quality of life. More attention should be paid to xerostomia in COVID-19 patients and survivors.

Abstract
With a reported prevalence between 20% and 30%, dry mouth is more common among older people than any other age group. The major risk factor for dry mouth is polypharmacy. Older people take more medications than any other age group, not only for symptomatic relief of various age-associated chronic diseases, but also to reduce the likelihood of the complications that may arise from those conditions. Most aged care residents take even more medications than older people who are living in their own homes. The greater the number of medications taken, the greater the associated anticholinergic burden, and the more likely it is that the individual will suffer from dry mouth. The condition not only affects the dentition and ability to wear dentures, but also the sufferers’ quality of life. Treating dry mouth is a considerable challenge for clinicians. As medication use is by far the most important risk factor, there is a need for pharmacists, doctors and dentists to work together to prevent this from occurring. Medication review and deprescribing is a key strategy, but there have not yet been any randomised control trials of its efficacy in reducing the occurrence of dry mouth.

COVID-19 Pandemic: Effect of Different Face Masks on Self-Perceived Dry Mouth and Halitosis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18179180. [PMID: 34501768 PMCID: PMC8431486 DOI: 10.3390/ijerph18179180] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/25/2021] [Accepted: 08/28/2021] [Indexed: 02/07/2023]
Abstract
Due to the COVID-19 pandemic, the use of face masks has increased, resulting in potential health-related side-effects. Therefore, the study aimed to analyse the effect of wearing face masks on self-perceived dry mouth and halitosis. A questionnaire addressing the daily wearing time of different face masks (community masks, surgical/medical masks and KN95-/N95-/FFP2-masks) and self-perceived dry mouth and halitosis was given to adults attending or working at a university hospital. Statistical analysis was performed using Wilcoxon signed-rank test and multiple linear regression analysis (p < 0.05). 3750 participants (age: 50.4 ± 15.5 years; 60.0% female) were included. During the pandemic, face masks were used for 4.7 ± 3.8 h per day: community masks: 0.9 ± 2.0 h, medical/surgical masks: 1.9 ± 2.8 h and KN95-/N95-/FFP2-masks: 1.9 ± 2.5 h per day. The use of face masks significantly increased self-perceived dry mouth and halitosis (both p < 0.001). Self-perceived dry mouth and halitosis increased with increasing wearing time (community masks: dry mouth: p < 0.001, halitosis: p = 0.014; medical/surgical masks: both: p < 0.001; KN95-/N95-/FFP2-masks: dry mouth: p < 0.001, halitosis: p = 0.011). The perception of dry mouth and halitosis was increased in females compared to males (both: p < 0.001). Participants used to wearing face masks prior to the pandemic perceived dry mouth to a higher extent (p = 0.043). Self-perceived halitosis was lower in older than in younger participants (p < 0.001). Due to the increased perception of dry mouth and halitosis, people might abstain from wearing face masks. Further studies need to analyse measurable changes in dry mouth or halitosis.

Abstract
Background: Patients under palliative care and their caregivers often ignore the dental treatment and oral hygiene needs as a result of which they face many day to day problems, which include difficulty in chewing, halitosis, and dry mouth eventually deteriorating the quality of life. Objective: The aim of this study is to understand the oral needs and oral health-related concerns of the patients under palliative care. Methodology: A total of eight patients agreed to enroll in the study. A detailed interview with oral examination, including Sillness and Loe Plaque Index and Decayed Missing and Filled Teeth (dmft) Index, was recorded. Patients were also given the treatment needed if willing for the same. Results: In our study, we observed that the mean dmft scores of dentulous patients were 7.96 ± 3.35, and mean plaque score was 1.75 ± 2.12, which was significantly higher and further highlights the need for dental treatment. Conclusion: The patients under palliative care have many oral problems such as dry mouth, difficulty in eating, halitosis which needs to be addressed; hence, dental health plays an important role in improving the quality of life of these patients.

Determinants of patient-reported xerostomia among long-term oropharyngeal cancer survivors. Cancer 2021; 127:4470-4480. [PMID: 34358341 DOI: 10.1002/cncr.33849] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 06/03/2021] [Accepted: 06/05/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND This study was conducted to identify clinicodemographic risk factors for xerostomia among long-term oropharyngeal cancer (OPC) survivors. METHODS This cross-sectional study included 906 disease-free, adult OPC survivors with a median survival duration at the time of survey of 6 years (range, 1-16 years); self-reported xerostomia scores were available for 877 participants. Study participants had completed curative treatment between January 2000 and December 2013 and responded to a survey administered from September 2015 to July 2016. The primary outcome variable was cancer patient-reported xerostomia measured with the MD Anderson Symptom Inventory Head and Neck Cancer Module. Clinicodemographic risk factors for moderate to severe xerostomia were identified via multivariable logistic regression. RESULTS Moderate to severe xerostomia was reported by 343 of the respondents (39.1%). Female sex (odds ratio [OR], 1.82; 95% CI, 1.22-2.71; P = .003; Bayesian false-discovery probability [BFDP] = 0.568), high school or lower education (OR, 1.73; 95% CI, 1.19-2.52; P = .004; BFDP = 0.636), and current cigarette smoking at the time of survey (OR, 2.56; 95% CI, 1.19-5.47; P = .016; BFDP = 0.800) were risk factors for moderate to severe xerostomia, and bilateral intensity-modulated radiotherapy (IMRT) combined with proton therapy and ipsilateral IMRT were protective. CONCLUSIONS In this large xerostomia study, modern radiotherapy was a protective factor, and continued cigarette smoking at the time of survey, female sex, and high school or lower education were identified as other contributing risk factors associated with moderate to severe xerostomia. Importantly, these findings need to be confirmed in prospective studies. These results can inform future research and targeted patient-centered interventions to monitor and manage radiation therapy-associated xerostomia and preserve quality of life among patients with OPC.

Abstract
BACKGROUND Dry mouth syndrome or xerostomia is defined as decreased salivary flow or hypofunction of salivary glands. Its origins are multicausal and might be the result of a change in the salivary glands or a systemic imbalance. OBJECTIVE To ascertain the prevalence of self-reported xerostomia and to identify associated factors. DESIGN AND SETTING Cross-sectional study on the entire population of 293 elderly people over 60 years of age living in a Brazilian municipality. METHODS Data were gathered from a questionnaire that asked about demographic data, chronic diseases and use of continuous medications, and which used the Xerostomia Inventory (XI) to evaluate dry mouth sensation. Our analysis consisted of multivariate regression and estimation of odds ratios (OR) and their respective 95% confidence intervals (CI) in binary logistic regression models. RESULTS The prevalence of self-reported xerostomia was 19.1%. Elderly people with diabetes had higher odds of having self-reported xerostomia (OR: 3.59; 95% CI: 1.48-8.68; P < 0.001) as did those who had chronic diseases and used continuous medication (OR: 2.3; 95% CI: 1.19-4.67; P = 0.009). Elderly people who used continuous medication for the gastrointestinal tract were more likely to have xerostomia (OR: 2.14; 95% CI: 1.03-1.44; P = 0.030). CONCLUSIONS Elderly people with diabetes and chronic diseases who were using continuous medication were more likely to have dry mouth. Use of continuous medications for the gastrointestinal tract led to a greater chance of having self-reported xerostomia.

Abstract
Initially, it was reported that coronavirus 2019 disease (Covid-19) affects respiratory, gastrointestinal and neurological systems, but the oral, olfactory and integumentary systems are also involved. This review discusses various oral manifestations of Covid-19 reported in the literature along with possible underlying mechanisms. The reported manifestations include taste impairment, oral mucosal changes (petechiae, ulcers, plaque-like lesions, reactivation of herpes simplex virus 1(HSV1), geographical tongue and desquamative gingivitis) and dry mouth. The prominent location for mucosal lesions are tongue, palate and labial mucosa. The exact pathogenesis of these oral symptoms is not known. Angiotensin-converting enzyme 2 (ACE2) cell receptors are expressed in abundance on oral mucosa allowing severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) to infect them. Gustatory impairment along with olfactory changes is now listed as a symptom of Covid-19 by the World Health Organization, but further research is needed to confirm a link between reported additional oral symptoms and Covid-19. Dental professionals may encounter individuals with Covid-19 and be called upon to identify various oral manifestations of this disease.

Abstract
Primary SS (pSS) is a systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands leading to glandular dysfunction, resulting in dryness of the eyes, mouth and other mucosal surfaces. Systemic manifestations also occur in the majority of patients. There has been increasing interest in recent years, with a number of publications regarding the classification criteria, diagnostic tools, disease activity, damage, impact and potential treatments. This article reviews recent advances in the diagnosis and treatment of ocular and oral involvement in pSS. Recent stand-out developments include measurement of tear osmolarity as a marker in dry eye disease diagnosis, new devices measuring tear constituents and meibomian gland structure and treatment of its dysfunction. Lip biopsy is still valuable despite emerging evidence of non-invasive diagnostic techniques, notably salivary gland ultrasound.

Abstract
Objective Non‐surgical scaling and root planing (SRP), as an initial form of periodontal treatment, followed by ongoing periodontal maintenance appointments is necessary to manage periodontal disease and prevent tooth loss. Saliva also has an essential role in oral health though the relationship between low salivary flow and periodontal outcomes has not been extensively investigated. This study determined if patients with dry mouth have similar clinical outcomes as patients without dry mouth when receiving regular periodontal maintenance after SRP. Materials and methods This is a retrospective study that investigated clinical periodontal outcomes in patients with (n = 34) or without (n = 85) dry mouth who had undergone SRP 1 to 5 years prior and had routine periodontal maintenance. The presence of dry mouth was established based on a patient's unstimulated salivary flow rate. Results Probing depth for both patients with or without dry mouth was similar between groups and maintained 1 to 5 years following initial SRP. Improved probing depth achieved post‐SRP was sustained regardless of dry mouth status. Conclusion Patients with or without dry mouth did not exhibit different probing depths.

Abstract
BACKGROUND Medication-induced xerostomia is common in older people. We investigated medication use and xerostomia in dependent older New Zealanders. METHODS Medication and xerostomia data analysed from a nationally representative survey of dependent older people. Automatic interaction detection analysis identified medications combinations most strongly associated with xerostomia, and then xerostomia was modelled. RESULTS Just over half were taking five to nine different medications; one in five was taking 10+. Xerostomia prevalence (29.4%; 95% confidence interval 26.5, 32.5) was higher among the latter and lowest in psychogeriatric patients. After controlling for age and sex, it was higher among people taking any antidepressant, and higher still with a tricyclic antidepressant and either a steroid or an anticholinergic, or among people taking a bronchodilator without prophylactic aspirin. CONCLUSIONS Health practitioners should work together to ensure that those with xerostomia are managed in a timely and appropriate manner. Medication review is an important component of that.

Abstract
OBJECTIVES To determine the subjective effectiveness of oilpulling on medication-induced xerostomia with regard to symptom relief, quality of life, taste, mucosal moisture and oral parameters. MATERIALS AND METHODS In a randomized, single-blind, crossover trial in participants with medication-induced xerostomia (n = 26; mean age 64.71 (standard deviation (SD) 15.60) years), we investigated oilpulling efficacy (sunflower oil) versus mineral water after one-week use. Xerostomic burden (visual analogue scale, VAS), symptom relief and oral examinations (gingivitis index, plaque index, whole stimulated and unstimulated salivation rates) were investigated at baseline and the end of the follow-up. RESULTS Oilpulling reduced the xerostomic burden (baseline value 6.46 (SD 1.80), decreasing to 4.93 (SD 2.97)) (p = .003), without difference between oil versus water (p = .067). Baseline values for water were 6.08 (SD 2.17) decreasing to 5.72 (SD 2.17) (p = .124). Compared to water, oil made swallowing easier (p = .031), caused a pleasant mouthfeel (p = .031) and caused less waking up at night (p = .031). Effectiveness (p = .002) and duration (p = .007) of symptom relief showed differences between products in favour of oil. CONCLUSIONS Oil pulling alleviated the overall xerostomic burden. In the comparison between oil and water, no difference regarding symptom relief could be shown. Patients should be informed of possibilities and limitations of oilpulling as inexpensive and easy-to-obtain alternative to commercially available products for short-term symptom relief.

Dry mouth diagnosis and saliva substitutes-A review from a textural perspective. J Texture Stud 2020; 52:141-156.

Abstract
The aim of this review is to assess the objective and subjective diagnosis, as well as symptomatic topical treatment of dry mouth conditions with a clear focus on textural perspective. We critically examine both the current practices as well as outline emerging possibilities in dry mouth diagnosis and treatment, including a patent scan for saliva substitutes. For diagnosis, salivary flow rates and patient-completed questionnaires have proven to be useful tools in clinical practice. To date, objective measurements of changes in mechanical properties of saliva via rheological, adsorption, and tribological measurements and biochemical properties of saliva such as assessing protein, mucins (MUC5B) are seldom incorporated into clinical diagnostics; these robust diagnostic tools have been largely restricted to application in non-clinical settings. As for symptomatic treatments of dry mouth, four key agents including lubricating, thickening, adhesive, and moisturizing agents have been identified covering the overall landscape of commercial saliva substitutes. Although thickening agents such as modified celluloses, polysaccharide gum, polyethylene glycol, and so forth are most commonly employed saliva substitutes, they offer short-lived relief from dry mouth and generally do not provide boundary lubrication properties of real human saliva. Innovative technologies such as self-assembly, emulsion, liposomes, and microgels are emerging as novel saliva substitutes hold promise for alternative approaches for efficient moistening and lubrication of the oral mucosa. Their adoption into clinical practice will depend on their efficacies, duration of relief, and ease of application by the practitioners and patient compliance.

Abstract
Sjögren's syndrome (SS) is a systemic autoimmune disorder affecting approximately 3% of the population in the United States. This disease has a female predilection and affects exocrine glands, including lacrimal and salivary glands. Dry eyes and dry mouths are the most common symptoms due to the loss of salivary and lacrimal gland function. Symptoms become more severe in secondary SS, where SS is present along with other autoimmune diseases like systemic lupus erythematosus, systemic sclerosis, or rheumatoid arthritis. It is known that aberrant activation of immune cells plays an important role in disease progression, however, the mechanism for these pathological changes in the immune system remains largely unknown. This review highlights the role of different immune cells in disease development, therapeutic treatments, and future strategies that are available to target various immune cells to cure the disease.

Detection of SARS-CoV-2 in saliva and characterization of oral symptoms in COVID-19 patients. Cell Prolif 2020; 53:e12923. [PMID: 33073910 PMCID: PMC7645955 DOI: 10.1111/cpr.12923] [Citation(s) in RCA: 105] [Impact Index Per Article: 26.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/16/2020] [Accepted: 09/20/2020] [Indexed: 01/08/2023] Open
Abstract
OBJECTIVES In order to provide a more comprehensive understanding of the effects of SARS-CoV-2 on oral health and possible saliva transmission, we performed RNA-seq profiles analysis from public databases and also a questionnaire survey on oral-related symptoms of COVID-19 patients. MATERIALS AND METHODS To analyse ACE2 expression in salivary glands, bulk RNA-seq profiles from four public datasets including 31 COVID-19 patients were recruited. Saliva and oropharyngeal swabs were collected. SARS-CoV-2 nucleic acids in saliva were detected by real-time polymerase chain reaction (RT-PCR). Additionally, a questionnaire survey on various oral symptoms such as dry mouth and amblygeustia was also carried out on COVID-19 patients. RESULTS ACE2 expression was present at detectable levels in the salivary glands. In addition, of four cases with positive detection of salivary SARS-CoV-2 nucleic acids, three (75%) were critically ill on ventilator support. Furthermore, we observed the two major oral-related symptoms, dry mouth (46.3%) and amblygeustia (47.2%), were manifested by a relatively high proportion of 108 COVID-19 patients who accepted the questionnaire survey. CONCLUSIONS This study confirms the expression of ACE2 in the salivary glands and demonstrates the possibility of SARS-CoV-2 infection of salivary glands. Saliva may be a new source of diagnostic specimens for critically ill patients, since it can be easily collected without any invasive procedures. In addition, dry mouth and amblygeustia can be considered as initial symptoms of COVID-19 infection.

Evaluation of the Saxon test for patients with hyposalivation without Sjögren's syndrome. J Oral Rehabil 2020; 47:1550-1556. [PMID: 32965698 DOI: 10.1111/joor.13093] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 08/20/2020] [Accepted: 09/04/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Dry mouth is associated with salivary gland hypofunction, which may result from several conditions such as Sjögren's syndrome (SS), head and neck cancers, and side effects of medications. The Saxon test is a useful diagnostic method for hyposalivation in clinical settings. However, previous reports indicate that the test has mostly been used for patients with SS. OBJECTIVE(S) In the present study, we focused on patients with dry mouth who were not diagnosed with SS (patients without SS). METHODS For patients without SS (n = 302), we examined the factors affecting Saxon test scores using multiple regression analysis. Additionally, we performed a correlation analysis comparing the Saxon test with other diagnostic methods. RESULTS In 57.6% patients, the Saxon test score was more than 2.00 g/2 min, which is considered negative for hyposalivation. Multiple regression analysis revealed that the age and sex of patients significantly influenced test scores. The mean Saxon test score was less than 2.00 g/2 min in older patients and women. Moreover, the test showed a significant correlation with other methods used to measure salivary flow. CONCLUSION The Saxon test is useful not only for patients with SS but also for patients without SS.

Abstract
BACKGROUND Little is known of the occurrence of dry mouth among Australians. AIM To describe the prevalence and associations of xerostomia in a nationally representative sample of Australian adults. METHODS Dentate persons aged 15+ years were asked 'How often does your mouth feel dry?' (response options 'never', 'occasionally', 'frequently' or 'always'). Those responding 'frequently' or 'always' were classified as xerostomic. RESULTS The prevalence of xerostomia was 13.2% (95% CI 12.4, 14.0). It ranged from 9.3% (95% CI 7.9, 10.8) among 15-to-34-year-old to 26.5% (95% CI 23.3, 30.0) among those aged 75+ years. Prevalence was higher in the lowest income tertiles (24.5%, 95% CI 22.6, 26.5), lowest SEIFA tertiles (15.7%, 95% CI 14.2, 17.3), those who were dentally uninsured (16.6%, 95% CI 15.4, 17.8) and those with unfavourable dental visiting patterns (18.1%, 95% CI 16.2, 20.1). CONCLUSIONS More than one in ten Australians experience dry mouth. Among older Australians, this estimate is one in four. With an ageing, medicated population that is increasing in size, xerostomia is a condition that needs to be better understood, recognized and managed by both dental and general health practitioners.

Abstract
Insufficient retention of water in adsorbed salivary conditioning films (SCFs) because of altered saliva secretion can lead to oral dryness (xerostomia). Patients with xerostomia sometimes are given artificial saliva, which often lacks efficacy because of the presence of exogenous molecules with limited lubrication properties. Recombinant supercharged polypeptides (SUPs) improve salivary lubrication by enhancing the functionality of endogenously available salivary proteins, which is in stark contrast to administration of exogenous lubrication enhancers. This novel approach is based on establishing a layered architecture enabled by electrostatic bond formation to stabilize and produce robust SCFs in vitro. Here, we first determined the optimal molecular weight of SUPs to achieve the best lubrication performance employing biophysical and in vitro friction measurements. Next, in an ex vivo tongue-enamel friction system, stimulated whole saliva from patients with Sjögren syndrome was tested to transfer this strategy to a preclinical situation. Out of a library of genetically engineered cationic polypeptides, the variant SUP K108cys that contains 108 positive charges and two cysteine residues at each terminus was identified as the best SUP to restore oral lubrication. Employing this SUP, the duration of lubrication (Relief Period) for SCFs from healthy and patient saliva was significantly extended. For patient saliva, the lubrication duration was increased from 3.8 to 21 min with SUP K108cys treatment. Investigation of the tribochemical mechanism revealed that lubrication enhancement is because of the electrostatic stabilization of SCFs and mucin recruitment, which is accompanied by strong water fixation and reduced water evaporation.

Abstract
Oral lubrication mediated by mucin and protein containing salivary conditioning films (SCFs) with strong water retainability can get impaired due to disease such as xerostomia, that is, a subjective dry mouth feel associated with the changed salivary composition and low salivary flow rate. Aberrant SCFs in xerostomia patient cause difficulties in speech, mastication, and dental erosion while the prescribed artificial saliva is inadequate to solve the complications on a lasting basis. With the growing aging population, it is urgently needed to propose a new strategy to restore oral lubrication. Existing saliva substitutes often overwhelm the aberrant SCFs, generating inadequate relief. Here we demonstrated that the function of aberrant SCFs in a patient with Sjögren syndrome can be boosted through mucin recruitment by a simple mucoadhesive, chitosan-catechol (Chi-C). Chi-C with different conjugation degrees (Chi-C7.6%, Chi-C14.5%, Chi-C22.4%) was obtained by carbodiimide chemistry, which induced a layered structure composed of a rigid bottom and a soft secondary SCF (S-SCF) after reflow of saliva. The higher conjugation degree of Chi-C generates a higher glycosylated S-SCF by mucin recruitment and a lower friction in vitro. The layered S-SCF extends the "relief period" for Sjögren patient saliva over 7-fold, measured on an ex vivo tongue-enamel friction system. Besides lubrication, Chi-C-treated S-SCF reduces dental erosion depths from 125 to 70 μm. Chi-C shows antimicrobial activity against Streptococcus mutans. This research provides a new key insight in restoring the functionality of conditioning film at articulating tissues in living systems.

In vitro three-dimensional culture systems of salivary glands. Pathol Int 2020; 70:493-501. [PMID: 32367629 DOI: 10.1111/pin.12947] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 04/20/2020] [Accepted: 04/22/2020] [Indexed: 12/18/2022]
Abstract
Dry mouth can be caused by salivary gland hypofunction due to Sjögren's syndrome (SS) or radiation therapy for head and neck cancer, and it can also be a side effect of medications. The use of sialagogues effectively increases saliva secretion in patients with dry mouth. However, the application of sialagogues is not always satisfactory because of their side effects, such as sweating, nausea, runny nose and diarrhea. Two-dimensional (2D) cell cultures have been used not only for drug screening and discovery but also to clarify disease mechanisms. However, three-dimensional (3D) cell cultures are expected to be even more advantageous than 2D cell cultures. Therefore, we have tried to develop an in vitro cell culture system that can reconstitute 3D salivary glands. Sox9 and Foxc1 were identified as important genes that differentiate mouse embryonic stem cell-derived oral ectoderm into salivary gland placode. Using these genes and organoid culture systems, we succeeded in generating salivary gland organoids that exhibited a morphology and gene expression profile that were similar to those of the embryonic rudiment from which salivary glands arise in normal mice. These organoids are expected to be a promising tool for disease modeling, drug discovery and regenerative medicine in salivary glands.
