Impact of tobacco habits on poor oral health status among bone-factory workers in a low literacy city in India: A cross-sectional study

Oral health is a vital indicator of well-being that is influenced by various habits and lifestyles of individuals. Oral diseases are the bottleneck in the effective control of non-communicable diseases (NCDs) due to chronic in nature and reciprocal relationship as sharing the common risk factors and habits such as sugar, tobacco, and alcohol consumption that increase the risk of developing various inevitable diseases. However, there is a lack of literature highlighting the relationship between risk factors for oral diseases and general health among individuals. This cross-sectional study was carried out among 500 study participants aged 20 to 64 years who gave written informed consent and were recruited by Multistage Stratified Cluster Sampling technique among workers in five bone factories, working for at least one year since January 2001 to March 2022 in Sambhal city, Uttar Pradesh. WHO-Basic Oral Health Survey-1997 was used to record the data regarding sociodemographic and oral health status variables. We used the modified WHO-STEPWISE pre-structured questionnaire to record tobacco consumption habits and oral health-seeking behavior. We scheduled a clinical intra-oral examination to record the Decayed Missing Filled Teeth (DMFT) index and the interview on the premises of five bone factories. Among the 500 bone-factory workers, the total number of males was 342 (68.40%) and 158 (31.60%) were females. The mean age (Standard Deviation) was 33.18 (10), and the mean DMFT score of factory workers was 2.84 (3.12). Production workers had the highest mean DMFT score of 4.60 (3.25). More than half of the factory workers (53.2%) were tobacco users. Tobacco users were 3.52 times more likely to have a severe DMFT index. Most common pre-cancerous lesions were oral submucous fibrosis and leukoplakia. Compared to non-tobacco users, mild tobacco users have 6.80 folds higher odds of oral lesions. Tobacco consumption is not only harmful for oral health but also leads to several non-communicable and systemic diseases. NCDs and dental caries are chronic and preventable conditions with a bidirectional relationship implicated by modifiable major risk factors such as tobacco consumption. Decreasing the consumption of tobacco use may improve oral health and reduce the risk of the development of NCDs. Also, regular dental visits should be scheduled to monitor the oral health status of factory workers. Additionally, tailored intervention for tobacco cessation should be implicated to maintain the general and oral health of industrial workers.

Oncogenic Oral Human Papillomavirus Clearance Patterns over 10 Years

BACKGROUND

Effective screening for oropharyngeal cancer is lacking. Four oncogenic HPV clearance definitions were explored to understand long-term natural history for persistent oncogenic oral HPV (oncHPV), the precursor of oropharyngeal cancer.

METHODS

Prospective multicenter cohort of participants living with/at-risk for HIV, with oral rinse and gargle samples collected every 6 to 12 months for up to 10 years and tested for oncHPV. HPV clearance definitions included 1 (clear1), 2 (clear2), 3 (clear3) consecutive negatives, or being negative at last two visits (clearlast).

RESULTS

Median time to clearance of oncHPV exceeded 2 years for conservative definitions (clear3: 2.38, clearlast: 2.43), but not lenient (clear1: 0.68, clear2: 1.15). By clear3, most incident infections cleared at 2, 5, 8 years (55.1%, 75.6%, 79.1%), contrary to prevalent infections (37.1%, 52.5%, 59.5%, respectively). In adjusted analysis, prevalent oncHPV, older age, male sex, and living with HIV were associated with reduced clearance. Of 1,833 subjects screened, 13.8% had prevalent oncHPV and 47.5% of those infections persisted ≥5 years, representing 6.5% of persons screened. Two men with prevalent oral HPV16 developed incident oropharyngeal cancer [IR = 1.62 per 100 person-years; 95% confidence interval (CI), 0.41-6.4]. Many with oral HPV16 persisted ≥5 years (and/or developed HPV-oropharyngeal cancer) among those with 2 (72.2%), ≥2 of first 3 (65.7%), or 3 (80.0%) consecutive positive oHPV16 tests, but not after 1 (39.4%).

CONCLUSIONS

In our 10-year study, most incident infections cleared quickly. However, half of prevalent oncHPV persisted ≥5 years, suggesting increased risk with persistent oncHPV at >2 visits.

IMPACT

We identified groups with persistent oncHPV at increased risk of oropharyngeal cancer and contextualized risk levels for those with oral HPV16 infection.

A Patient With Oral Discomfort and Reduced Oral Aperture

A patient had burning and pain in the mouth, reduced oral aperture, white-tan plaques on the oral mucosa, and thickened buccal mucosae bilaterally; biopsy of the lower labial mucosa showed subepithelial fibrosis. She had no history of cigarette smoking or use of chewing tobacco but had current and past history of chewing areca nuts. What is the diagnosis and what would you do next?

Phage therapy: A renewed approach against oral diseases caused by Enterococcus faecalis infections

Antibiotics play an important role in the treatment of infectious diseases. Long-term overuse or misuse of antibiotics, however, has triggered the global crisis of antibiotic resistance, bringing challenges to treating clinical infection. Bacteriophages (phages) are the viruses infecting bacterial cells. Due to high host specificity, high bactericidal activity, and good biosafety, phages have been used as natural alternative antibacterial agents to fight against multiple drug-resistant bacteria. Enterococcus faecalis is the main species detected in secondary persistent infection caused by failure of root canal therapy. Due to strong tolerance and the formation of biofilm, E. faecalis can survive the changes in pH, temperature, and osmotic pressure in the mouth and thus is one of the main causes of periapical lesions. This paper summarizes the advantages of phage therapy, its applications in treating oral diseases caused by E. faecalis infections, and the challenges it faces. It offers a new perspective on phage therapy in oral diseases.

The impact of osteogenesis imperfecta severity on oral health-related quality of life in Spain: a cross-sectional study

BACKGROUND

Osteogenesis imperfecta (OI) affects dental and craniofacial development; therefore, it can influence oral health-related quality of life (OHRQoL). The objective of this study was to explore the influence of the severity of OI on OHRQoL in adults older than eighteen years residing in Spain.

METHOD

Adults with OI were recruited from the Spanish Association of Crystal Bone (AHUCE) foundation. OHRQoL was evaluated using the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14sp), oral hygiene habits, and a dental care survey. Clinical and radiological dental examinations were performed to evaluate the patients' oral conditions.

RESULTS

A total of 65 adults (n = 46 females) aged between nineteen and sixty-two years who were diagnosed with OI and classified as type I, III, and IV (n = 20, 14, and 31, respectively) participated in this research. The total OHIP-14sp scores were significantly greater (worse) for type III (23 [SD = 10]) and type IV (21.4 [SD = 12]) than for type I (13.8 [SD = 6]) (P < 0.05). The negative impact of OHRQoL was due to the association of type III OI with all domains except for the handicap domain, while type IV OI was associated with the physical disability, social disability, and handicap domains (P < 0.05 for all).

CONCLUSION

The severity of OI negatively impacted OHRQoL in adults. This association was statistically significant.

Sugar intake above international recommendations and oral disease burden: A population-based study

OBJECTIVE

To evaluate the association between added sugar intake above the daily limit for the risk of noncommunicable diseases (NCDs) and the Chronic Oral Disease Burden in adolescents.

METHODS

This was a population-based study using cross-sectional data nested to RPS Cohorts Consortium, São Luís, Brazil, from the 18-19-year-old follow-up (n = 2515). High consumption of added sugars was estimated according to the limits of the World Health Organization guidelines (WHO) (≥5% of total energy/day) and the American Heart Association statement (AHA) (≥25 g/day). The Chronic Oral Disease Burden was a latent variable (number of decayed teeth, periodontal probing depth ≥4 mm, clinical attachment level ≥3 mm, and bleeding on probing). Models were adjusted for Socioeconomic Status, sex, obesity, and plaque index and analyzed through structural equation modeling.

RESULTS

Adolescents had high sugar consumption according to the WHO (78.6%) and AHA (81.4%) recommendations. High sugar intake, according to WHO (SC = 0.096; p = 0.007) and AHA (SC = 0.056; p = 0.027), was associated with a heavier Chronic Oral Disease Burden. Even half of the recommended dose was sufficient to affect some oral disease indicators.

CONCLUSION

Sugar intake over international statements to prevent NCDs is associated with higher Chronic Oral Disease Burden among adolescents.

Outreach dental care programme for older adults using long-term care services in Hong Kong: A qualitative study

OBJECTIVES

To explore the effects and improvement needs of an outreach dental care programme (ODCP) for older adults using residential care or daycare services from the perspectives of the caregivers, the dentists and administrative staff involved in the implementation of the ODCP.

METHODS

A qualitative study was conducted through semi-structured interviews with three stakeholders, long-term care (LTC) facility caregivers, administrative staff and dentists working for the ODCP. Combined maximum variation and snowball sampling strategies were adopted, and 22, 9 and 7 participants were interviewed from each stakeholder, respectively. The interviews were conducted via telephone, which were audio-recorded and transcribed verbatim for analysis. NVivo software was used for storing and analysing the data. Data analysis was conducted continuously during the study.

RESULTS

Most participants opined that the ODCP benefited older adults by raising their oral health conditions and awareness. However, they complained of the complicated administrative procedures, unmet dental treatment needs, inefficient coordination, unclear work guidelines and shortage of dental manpower. More advanced dental treatment options, better coordination among different parties, simpler administrative processes and better incentives for dentists were proposed to further improve the programme.

CONCLUSIONS

According to the stakeholders, ODCP seems beneficial to older adults using LTC services. Further improvements in the scope of dental treatments, cooperation between the outreach dental teams and caregivers, and streamlining of the administrative process are needed for the provision of effective outreach dental care to satisfy the unmet treatment needs of older adults who use LTC services. Better incentives are needed to attract and retain dentists.

Oral active matrix metalloproteinase-8 immunotest may be less accurate in haemato-oncologic patients

OBJECTIVES

This study examines the associations of active matrix metalloproteinase-8 (aMMP-8) point-of-care immunotest (Periosafe) outcomes with oral health of patients with haemato-oncologic diseases.

METHODS

Adult patients diagnosed with haematological diseases aimed to be treated with haematopoietic stem cell transplantation (HSCT) between 2018 and 2019 were included in the study. Clinical and radiological dental examination were taken immediately prior to transplantation. The presence of oral foci of infections, caries or periodontitis was examined and compared with the outcomes of aMMP-8 immunotest.

RESULTS

Acute oral infection foci were present in 11.9%, chronic in 44.1% and periodontitis in 42.0% of the 143 subjects. aMMP-8 immunotest was positive in 13.3% of all the 143 subjects. Among subjects with periodontitis (n = 60), the aMMP-8 immunotest was also positive in 13.3% of these subjects. However, the subjects with positive aMMP-8 immunotest (n = 19) had more often acute or chronic infection foci and more than one of the examined dental treatment needs compared with subjects with negative immunotest (all p < 0.05). There were no differences in age, sex, hyposalivation, DMFT-index values nor with plasma levels of leukocytes, neutrophils or C-reactive protein between subjects with positive or negative aMMP-8 immunotest.

CONCLUSIONS

aMMP-8 immunotest accuracy might be reduced, in relation to periodontitis, in haemato-oncologic patients.

Oral cancer and oral potentially malignant disorders in patients with Fanconi anemia - A systematic review

The purpose of the present study was to perform a systematic review focusing on oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) in Fanconi anemia (FA) individuals. Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature. Case reports and/or cases series were included. The searches yielded 55 studies describing 112 cases of OSCC (n = 107) and/or OPMD (n = 5) in FA individuals. The mean age at diagnosis of OSCC/OPMD was 27.1 (±9.6) years, and females (51.8 %) were slightly more affected. Ulcer (n = 37) or mass (n = 25) were described as clinical presentations for OSCC and OPMD. White lesions (n = 4) were the most common manifestation in OPMD. Tongue (47.2 %) was the most frequent location. Sixty-one (54.5 %) individuals underwent HSCT. Surgical resection (n = 75) was the main treatment adopted. The estimated rate of OPMD malignant transformation was 1.8 % and recurrences following OSCC excision occurred in 26.8 % of individuals. Overall, at 60 months of follow-up, the probability of survival fell to 25.5 % and at 64 months the probability of recurrence increased to 63.2 %. The present data support the need for strict surveillance of patients with FA, even in the absence of OPMD, for early OSCC detection and reduction of mortality.

[Bionic design, preparation and clinical translation of oral hard tissue restorative materials]

Oral diseases concern almost every individual and are a serious health risk to the population. The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour. Based on the principle of "learning from the nature", Deng Xuliang's group of Peking University School and Hospital of Stomatology has proposed a new concept of "microstructural biomimetic design and tissue adaptation of tooth/jaw materials" to address the worldwide problems of difficulty in treating dentine hypersensitivity, poor prognosis of restoration of tooth defects, and vertical bone augmentation of alveolar bone after tooth loss. The group has broken through the bottleneck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects, and invented key technologies such as crystalline/amorphous multi-level assembly, ion-transportation blocking, and multi-physical properties of the micro-environment reconstruction, etc. The group also pioneered the cationic-hydrogel desensitizer, digital stump and core integrated restorations, and developed new crown and bridge restorative materials, gradient functionalisation guided tissue regeneration membrane, and electrically responsive alveolar bone augmentation restorative membranes, etc. These products have established new clinical strategies for tooth/jaw defect repair and achieved innovative results. In conclusion, the research results of our group have strongly supported the theoretical improvement of stomatology, developed the technical system of oral hard tissue restoration, innovated the clinical treatment strategy, and led the progress of the stomatology industry.

A scoping assessment of dental services at designated head and neck cancer centres in Ontario, Canada

BACKGROUND

Dentists serve a crucial role in managing treatment complications for patients with head and neck cancer, including post-radiation caries and oral infection. To date, dental services for head and neck cancer patients in Ontario, Canada have not been well characterized and considerable disparities in allocation, availability, and funding are thought to exist. The current study aims to describe and assess the provision of dental services for head and neck cancer patients in Ontario.

METHODS

A mixed methods scoping assessment was conducted. A purposive sample of dentist-in-chiefs at each of Ontario's 9 designated head and neck cancer centres (tertiary centres which meet provincially-set quality and safety standards) was invited to participate. Participants completed a 36-item online survey and 60-minute semi-structured interview which explored perceptions of dental services for head and neck cancer patients at their respective centres, including strengths, gaps, and inequities. If a centre did not have a dentist-in-chief, an alternative stakeholder who was knowledgeable on that centre's dental services participated instead. Thematic analysis of the interview data was completed using a mixed deductive-inductive approach.

RESULTS

Survey questionnaires were completed at 7 of 9 designated centres. A publicly funded dental clinic was present at 5 centres, but only 2 centres provided automatic dental assessment for all patients. Survey data from 2 centres were not captured due to these centres' lack of active dental services. Qualitative interviews were conducted at 9 of 9 designated centres and elicited 3 themes: (1) lack of financial resources; (2) heterogeneity in dentistry care provision; and (3) gaps in the continuity of care. Participants noted concerning under-resourcing and limitations/restrictions in funding for dental services across Ontario, resulting in worse health outcomes for vulnerable patients. Extensive advocacy efforts by champions of dental services who have sought to mitigate current disparities in dentistry care were also described.

CONCLUSIONS

Inequities exist in the provision of dental services for head and neck cancer patients in Ontario. Data from the current study will broaden the foundation for evidence-based decision-making on the allocation and funding of dental services by government health care agencies.

The most common types of nontraumatic dental conditions among emergency department visits in North Carolina before and during the COVID-19 pandemic

BACKGROUND

This study aimed to identify the most common types of nontraumatic dental conditions (NTDCs) before and during the COVID-19 pandemic and assess the variations in the most common NTDCs by patient age groups and rural or urban locations and the impact of COVID-19 on emergency department (ED) visits for NTDCs in North Carolina.

METHODS

The authors conducted a retrospective data analysis of ED data from the North Carolina Disease Event Tracking and Epidemiology Collection Tool. The authors estimated the proportions of NTDCs of all ED visits in 2019 and 2021 and ranked the proportions of the major categories of NTDCs by age groups and rural or urban locations. They used a multiple logistic regression model to assess the impact of COVID-19 on NTDCs.

RESULTS

By the first diagnosis, the proportion of NTDCs dropped from 1.1% in 2019 to 0.99% in 2021 (P < .001). Caries was specified as the third most common NTDC. Oral infection was the top NTDC among young (≤ 17 years) and older patients (≥ 65 years). No significant differences were found in NTDCs between rural and urban areas (P = .68). Children younger than 2 years (adjusted odds ratio, 4.36) and adults aged 18 through 44 years (adjusted odds ratio, 4.54) were more likely to visit the ED for NTDCs than those 75 years and older.

CONCLUSIONS

The proportion of NTDCs seen at the ED was lower during the COVID-19 pandemic in 2021 than in 2019. The common NTDCs varied by age group but were similar in rural and urban areas. The most common NTDCs were related to toothache, oral infection, and caries.

PRACTICAL IMPLICATIONS

More efforts are needed to reduce ED visits for NTDCs.

Topical applications of heterologous platelet rich plasma (PRP) for refractory gingival lesions in autoimmune blistering diseases

BACKGROUND

Recalcitrant gingival erosions, blisters and desquamative gingivitis are common features in oral autoimmune blistering diseases (AIBD). First line treatments include high-dosage corticosteroids and other immunosuppressive drugs, with several side effects and elevated number of recurrences. Autologous platelet-rich plasma (PRP) has been recently introduced as an alternative treatment and its use seems to be promising and safe.

METHODS

In this study we describe the use of topical application of heterologous PRP in nine patients affected by mucous membrane pemphigoid, with gingival lesions refractory to previous treatments. Topical applications of PRP were performed once a week for 2 months and the endpoint for clinical evaluation was set 3 months after the last session. Oral disease severity score (ODSS) and VAS scores for pain measurement were recorded before and after treatment.

RESULTS

The procedure was painless, well accepted, and free from adverse reactions. All patients (100%) reported a reduction in VAS whereas reduction in ODSS was observed in 89% of patients.

CONCLUSIONS

Within the limits of the study, topical heterologous PRP is a safe and promising procedure to be studied in future controlled randomized trials as adjuvant treatment for refractory gingival lesions in patients with AIBDs.

Reported physical examination methods for screening of oral cancer and oral potentially malignant disorders: a systematic review

OBJECTIVE

This systematic review aimed to describe the method followed during physical examination and the anatomical structures of the head and neck assessed in screening for oral cancer and oral potentially malignant disorders (OPMDs).

STUDY DESIGN

An extensive literature search was carried out using MEDLINE/PubMed, EMBASE, Scopus, LILACS, Web of Science, Cochrane databases, and gray literature. The risk of bias was available in all papers included.

RESULTS

Of 9,688 records identified, 27 were included in this review, reporting data from 356,250 individuals screened and distributed across 11 countries. Most of these (n = 19) were based on 1 round of screening conducted by a dental professional or other health care workers. Most screening programs included visual inspection and palpation of the lips, oral cavity, and the most visible oropharyngeal sites, but the descriptions reported were imprecise. Additional inspection and palpation of the neck (submental, submandibular, cervical, and supraclavicular regions) to assess for the presence of swellings and any palpable neck nodes were also performed in 15 programs.

CONCLUSION

In conclusion, there was considerable heterogeneity in the method of physical examination in screening programs for oral cancer and OPMDs among the included studies.

A brief review of cytology in dentistry

Oral cytology is a non-invasive adjunctive diagnostic tool with a number of potential applications in the practice of dentistry. This brief review begins with a history of cytology in medicine and how cytology was initially applied in oral medicine. A description of the different technical aspects of oral cytology is provided, including the collection and processing of oral cytological samples, and the microscopic interpretation and reporting, along with their advantages and limitations. Applications for oral cytology are listed with a focus on the triage of patients presenting with oral potentially malignant disorders and oral mucosal infections. Furthermore, the utility of oral cytology roles across both expert (for example, secondary oral medicine or tertiary head and neck oncology services) and non-expert (for example, primary care general dental practice) clinical settings is explored. A detailed section covers the evidence-base for oral cytology as a diagnostic adjunctive technique in both the early detection and monitoring of patients with oral cancer and oral epithelial dysplasia. The review concludes with an exploration of future directions, including the integration of artificial intelligence for automated analysis and point of care 'smart diagnostics', thereby offering some insight into future opportunities for a wider application of oral cytology in dentistry.

Self-assessment of dental health status, behaviours and oral health risk factors among adolescents from public schools in Maputo City-Mozambique

Self-assessment of dental health status may have an impact on the oral health behaviour of adolescents which could impact their oral health. Oral health has been linked to various medical health conditions, thus eliminating oral health diseases can improve general health. The present study aimed to assess the association between behaviours and risk factors (oral hygiene habits, sugar intake, urban/rural status) and negative self-perception of dental health status among adolescents attending public schools in Maputo City.Method An analytic cross-sectional study, conducted in three Primary public schools from urban and peri-urban areas in Maputo City selected by convenience due to their geographic location was included. The size of the sample was 236 12-year-olds. Data was collected using a self-completion questionnaire designed by the World Health Organization (WHO). Chi-square tests or Fishers' Exact tests were used for associations. A simple and multiple logistic regression was used to determine the strength of these associations using backward elimination (p < 0.05). Results: The sample consisted of 221 adolescents, with 114 (51.6%) residing in urban areas and 107 (48.4%) in peri-urban areas. More than half of the participants (111 individuals) reported having a negative perception of their dental health. In the urban location, a higher percentage of participants had a "negative" perception of dental health (57.9%, n = 66), while in the peri-urban location, more participants perceived their dental health as "positive" (57.9%, n = 62). Participants residing in an urban setting were 82% more likely to have a negative perception of dental health (AOR = 1.82 [95% C.I.: 1.05 to 3.14]). Those who had experienced dental pain tended to report a higher proportion of negative dental perception (57.2%, n = 91), with 2.7 times more likely to report a negative perception of dental health (AOR = 2.72 [95% C.I.: 1.46 to 5.08]). The majority (n = 139; 63.2%) claimed to clean their teeth twice a day.Conclusion There was a higher negative perception of dental health in urban areas. The need to strengthen oral health promotion in urban schools is high since schools play such a significant role in oral health promotion.

Salivary metabolomics in oral potentially malignant disorders and oral cancer patients-a systematic review with meta-analysis

OBJECTIVES

The aim of this systematic review and meta-analysis is to assess the diagnostic potential of salivary metabolomics in the detection of oral potentially malignant disorders (OPMDs) and oral cancer (OC).

MATERIALS AND METHODS

A systematic review was performed in accordance with the 3rd edition of the Centre for Reviews and Dissemination (CRD) and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Electronic searches for articles were carried out in the PubMed, Web of Science, and Scopus databases. The quality assessment of the included studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale (NOS) and the new version of the QUADOMICS tool. Meta-analysis was conducted whenever possible. The effect size was presented using the Forest plot, whereas the presence of publication bias was examined through Begg's funnel plot.

RESULTS

A total of nine studies were included in the systematic review. The metabolite profiling was heterogeneous across all the studies. The expression of several salivary metabolites was found to be significantly altered in OPMDs and OCs as compared to healthy controls. Meta-analysis was able to be conducted only for N-acetylglucosamine. There was no significant difference (SMD = 0.15; 95% CI - 0.25-0.56) in the level of N-acetylglucosamine between OPMDs, OC, and the control group.

CONCLUSION

Evidence for N-acetylglucosamine as a salivary biomarker for oral cancer is lacking. Although several salivary metabolites show changes between healthy, OPMDs, and OC, their diagnostic potential cannot be assessed in this review due to a lack of data. Therefore, further high-quality studies with detailed analysis and reporting are required to establish the diagnostic potential of the salivary metabolites in OPMDs and OC.

CLINICAL RELEVANCE

While some salivary metabolites exhibit significant changes in oral potentially malignant disorders (OPMDs) and oral cancer (OC) compared to healthy controls, the current evidence, especially for N-acetylglucosamine, is inadequate to confirm their reliability as diagnostic biomarkers. Additional high-quality studies are needed for a more conclusive assessment of salivary metabolites in oral disease diagnosis.

The use of E-cigarettes as a risk factor for oral potentially malignant disorders and oral cancer: a rapid review of clinical evidence

BACKGROUND

The popularity of e-cigarettes has increased rapidly in the last decade, particularly among teens and young adults, being advertised as a less harmful alternative to conventional tobacco products. However, in vitro and in vivo studies have evidenced a variable quantity of potentially harmful components and some recognized carcinogens which may cause DNA damage in oral cells. Additionally, evidence suggests that e-cigarettes may play active roles in the pathogenesis of other malignancies, such as lung and bladder cancers. Therefore, this rapid review aimed to assess the available clinical evidence about using e-cigarettes as a risk factor for oral potentially malignant disorders (OPMD) and oral cancer.

MATERIAL AND METHODS

A systematic search for English language articles published was performed in PubMed (MEDLINE), Embase, Scopus, and Web of Science. After the study selection process, the authors included twelve clinical studies about OPMD and oral cancer risk in e-cigarette users.

RESULTS

The main findings showed the presence of carcinogenic compounds in saliva and morphologic changes, DNA damage, and molecular pathways related to carcinogenesis in the oral cells of e-cigarette users. However, results were inconsistent compared to tobacco smokers and control groups.

CONCLUSIONS

the current clinical evidence on this topic is limited and insufficient to support using e-cigarettes as a risk factor for OPMD and oral cancer. Nevertheless, dental care professionals should advise patients responsibly about the potentially harmful effects of e-cigarettes on the oral mucosa cells. Future long-term and well-designed clinical studies are needed.

Proliferative verrucous leukoplakia/multifocal leukoplakia in patients with and without oral submucous fibrosis

BACKGROUND

Oral submucous fibrosis (OSF) and proliferative verrucous leukoplakia (PVL) are established as oral potentially malignant disorders. Dual pathology of the two conditions is not commonly encountered in clinical practice. This study aims to present a case series of multifocal leukoplakia in patients with and without OSF to outline the clinical behavior and challenges in the management of this high-risk group in clinical practice.

MATERIAL AND METHODS

We retrospectively analyzed cases of six Indian patients (four with OSF) managed over a period of 5.5 to 13 years at the Government Dental College, Nagpur. Patient data consisting of age, gender, medical history, habits, clinical findings, and biopsy reports were recorded at the initial visit. During follow-up visits, the clinicopathological data were reassessed. When surgical intervention failed to arrest the disease or when surgery was contraindicated metronomic therapy with Folitrax 15 mg once a week and Celecoxib 100mg twice daily was initiated.

RESULTS

All patients developed PVL after the initial pathology diagnosis of OSF or oral leukoplakia. Initial lesions were either homogenous or non-homogenous leukoplakia. All patients developed multiple recurrences, regional or systemic metastasis. Despite thorough interventions, the patients died of, or with the disease.

CONCLUSIONS

The occurrence of two or more oral potentially malignant disorders poses challenges in patient management and possibly presents a higher risk of malignant transformation. More clinical trials are necessary to assess the benefits of metronomic therapy for patients diagnosed with aggressive PVL concurrently found with OSF.

Guideline for the Diagnosis and Clinical Management of Oral Submucous Fibrosis

Oral submucous fibrosis (OSF) is a chronic, progressive and potentially malignant oral mucosal disease. Patients often have a habit of chewing betel nuts. Areca catechu has been listed as a Class 1 carcinogen by the International Agency for Research on Cancer (IARC), and its main active component, arecoline, is classified as a Group 2B carcinogen by the IARC. The World Health Organization (WHO) categorises OSF as an oral potentially malignant disorder (OPMD). The present guideline describes the risk factors, clinical symptoms and clinical signs of OSF. Clinical staging, auxiliary examination methods, basis for diagnosis and differential diagnosis and the need to improve bad lifestyle habits are proposed and addressed, and local treatment drugs, therapies, dosage and course of treatment, possible adverse reactions, and oral treatment drugs, dosage and course of treatment are proposed. The guideline also addresses the indications for surgical treatment, alternative non-drug treatment methods, selection of treatment plans for different clinical stages, criteria for efficacy evaluation, and preventive measures.

Pathogenesis and preventions of denture stomatitis

Denture stomatitis (DS) is one of the frequent oral diseases caused by multiple factors among denture wearers and is an erythematous lesion of the mucosa in the denture-bearing area, which is a limited and non-specific damage that seriously endangers the oral health of denture wearers. Traditional drug treatment for DS is effective, but it is prone to the development of drug-resistant strains. Therefore, it is important to find new treating options. For the prevention and treatment of DS, there are various methods such as direct administration of azole and polyene antibiotics to the mucosal lesions, extra-oral cleaning of the denture by cleansers and physical disinfection, and modification of denture materials. Natural ingredient preparations that have emerged in recent years are safe, convenient, inexpensive, and less likely to produce drug-resistant strains, and are seen as new sources of drugs for DS treatment. Photodynamic therapy has shown superior antibacterial properties and is also considered promising due to the convenience and safety of the treatment process and the ease of developing drug resistance. Antibacterial agents endow dentures with new characteristics, and denture modification will be a new way to treat DS. In addition, combining different prevention and control methods has shown better antibacterial activity against Candida albicans, which also provides new ideas for prevention and treatment of DS in the future.

An Exploratory Research Comparing Oral Health, Pattern of Substance Abuse and Nicotine Dependence among LGBT, Female Sex Workers and Heterogenders

AIM

Lesbian, gay, bisexual, transgender, and queer (LGBTQ), female sex workers (FSW), and heterogenders are those unconventional groups of the society who are identified with major unacceptance. Thus, the present study is conducted to assess and compare the oral health status, substance abuse pattern and nicotine dependence using Fagerstrom nicotine dependence scale (FNDP) among the LGBTQ, FSW, and heterogender in a defined location of Gautam Buddha Nagar, district in West U.P.

MATERIALS AND METHODS

The present exploratory research included three study groups, the LGBTQ, FSW, and heterogenders (HG) residing in the same habitat. Purposive snowball sampling was conducted for the accessibility of the unapproachable population in the defined geographical location at Gautam Budha Nagar, district in West Uttar Pradesh. The data collection of a total of 177 participants was done using a pre-validated, pretested proforma consisting of three different parts including WHO oral health assessment form for adults, 2013, questionnaire regarding pattern of substance abuse and FNDS. Data were recorded and statistically analyzed using SPSS.

RESULTS

Prevalence of oral health disorders including dental caries, periodontal disease as well as oral mucosal lesions were more commonly found among the LGBTQ participants followed by FSW and the differences were found to be statistically significant. In context of altered habits, 100% of the participants in the present study were reported with smokeless tobacco habits whereas majority of the FSW were reported with a habit of smoking tobacco.

CONCLUSION

In addition to belonging to ethnic and sexual minority, and having minimal or low education status, and low socioeconomic status, the present study groups are reported to have suboptimal access to quality healthcare and are further reported with high level of substance abuse as well as nicotine dependence.

CLINICAL SIGNIFICANCE

The present study is an attempt to provide base line data for further research and provide data to the policy makers so as to increase the healthcare access to the present groups.

Oral mucosal diseases and psychosocial factors: progress in related neurobiological mechanisms

The aetiology of oral mucosal diseases, such as recurrent aphthous ulcer (RAU), oral lichen planus (OLP) and burning mouth syndrome (BMS), involves many factors, and it remains difficult for clinicians to effectively relieve disease symptoms and formulate coping strategies. With the rapid development of psychology, the role of mental and psychological factors in RAU, OLP and BMS has gradually attracted researchers attention, but the specific mechanism has not been completely determined. This narrative review describes the potential neurobiological mechanism of oral mucosal diseases and detailed psychological factors after introducing relevant research into psychological factors and oral mucosal diseases. Future research strategies and innovations needed to understand and treat oral mucosal diseases and psychological factors, as well as how to prevent oral mucosal diseases by regulation of the neuroendocrine system, are also discussed.

Community-based Screening of Oral Cancer in Selected Districts of Nepal: A Cross-Sectional Study

OBJECTIVE

Oral cancer screening plays a vital role in the prevention and control of oral cancer. This study aimed to determine the prevalence of oral potentially malignant disorders (OPMDs) in the Nepalese community.

METHODS

A cross-sectional study was conducted in six purposively selected districts in Nepal from May to December 2019. It utilized a camp-based approach, where a standardized questionnaire was administered through face-to-face interviews. Screening of oral cancer was performed by direct visualization and palpation. The study included adults aged 18 years and above, while those already diagnosed with oral cancer were excluded. Logistic regression was used to find out the association between OPMDs and the related variables.

RESULTS

A total of 1930 participants with a mean age of 44.3 years (SD=15.1) underwent oral cancer screening. Among them, 32% were current tobacco users, 2% were ex-users, and 11% were alcohol consumers. OPMDs, including suspected cancer, were identified in 139 (7.2%, 95% CI=6.1-8.4) participants. The most common lesion detected was leukoplakia (4.2%), followed by submucous fibrosis (1.5%), erythroplakia (0.9%), and palatal changes due to reverse smoking (0.1%). Additionally, 10 participants were suspected of having oral cancer. Older age group (AOR=7.00; 95% CI=2.76-17.77), male gender (AOR=2.52; 95% CI=1.58-4.02), tobacco chewers (AOR = 14.30; 95% CI=8.82-23.19), and smokers (AOR=4.67; 95% CI=2.88-7.57)) were identified as predictors of OPMDs.

CONCLUSION

This study revealed a high prevalence of OPMDs in Nepal, highlighting the need for oral cancer screening. The findings emphasize the importance of developing strategies to reduce tobacco use and implementing tobacco cessation intervention programs in Nepal to alleviate the burden of oral cancer.

Inter-observer agreement among specialists in the diagnosis of oral potentially malignant disorders and oral cancer using store-and-forward technology

OBJECTIVES

Oral cancer is a leading cause of morbidity and mortality. Screening and mobile Health (mHealth)-based approach facilitates early detection remotely in a resource-limited settings. Recent advances in eHealth technology have enabled remote monitoring and triage to detect oral cancer in its early stages. Although studies have been conducted to evaluate the diagnostic efficacy of remote specialists, to our knowledge, no studies have been conducted to evaluate the consistency of remote specialists. The aim of this study was to evaluate interobserver agreement between specialists through telemedicine systems in real-world settings using store-and-forward technology.

MATERIALS AND METHODS

The two remote specialists independently diagnosed clinical images (n=822) from image archives. The onsite specialist diagnosed the same participants using conventional visual examination, which was tabulated. The diagnostic accuracy of two remote specialists was compared with that of the onsite specialist. Images that were confirmed histopathologically were compared with the onsite diagnoses and the two remote specialists.

RESULTS

There was moderate agreement (k= 0.682) between two remote specialists and (k= 0.629) between the onsite specialist and two remote specialists in the diagnosis of oral lesions. The sensitivity and specificity of remote specialist 1 were 92.7% and 83.3%, respectively, and those of remote specialist 2 were 95.8% and 60%, respectively, each compared with histopathology.

CONCLUSION

The diagnostic accuracy of the two remote specialists was optimal, suggesting that "store and forward" technology and telehealth can be an effective tool for triage and monitoring of patients.

CLINICAL RELEVANCE

Telemedicine is a good tool for triage and enables faster patient care in real-world settings.

Human Papillomavirus-Associated Oral Epithelial Dysplasia: Report of 5 Illustrative Cases from Latin America

BACKGROUND

Human papillomavirus-associated oral epithelial dysplasia (HPV-OED) is a distinct oral epithelial disorder characterized by viral cytopathic changes caused by transcriptionally active high-risk HPV. The aim of the present study was to report 5 additional cases from Latin America.

METHODS

Clinical data from five patients with HPV-OED were obtained from the archives of three oral pathology services from Brazil and Chile. All cases were submitted to morphological, p16 expression and in situ hybridization (ISH) for HPV analyses.

RESULTS

Four patients were male and one patient was female, with a mean age of 55.4 years. Four patients were HIV seropositive and two were smokers. Three cases affected the buccal mucosa and commissure, one of which had an additional plaque in the soft palate, and one case each occurred on the floor of mouth and lower labial mucosa. Most cases presented as well-demarcated white plaques with a verrucous surface. One case presented multiple lesions ranging from normal to white-colored slightly elevated plaques with a cobblestone surface. Peripheral mucosal pigmentation was observed in two cases. All five cases presented with the characteristic microscopic features of HPV-OED, including severe dysplasia with numerous karyorrhectic and apoptotic cells, full-thickness "block positivity" for p16 and high Ki-67 index (> 90%) sharply demarcated from the adjacent non-dysplastic epithelium. Wide-spectrum DNA ISH-HPV was positive in 4 cases. All patients were treated with conservative surgical excision with no signs of recurrence after a mean of 39-month follow-up.

CONCLUSION

This represents the first series of HPV-OED from Latin America; most cases presented as well-demarcated papillary white plaques affecting the buccal mucosa and commissure of HIV-positive middle-aged men, two of them exhibiting peripheral pigmentation caused by reactive melanocytes. The typical microscopic findings of HPV-OED were observed in all cases, which also showed strong p16 positivity in a continuous band through the full thickness of the epithelium and high Ki67.

Oral erythroplakia and oral erythroplakia-like oral squamous cell carcinoma - what's the difference?

BACKGROUND

Oral erythroplakia (OE) is a rare oral potentially malignant disorder, that has a high rate of malignant transformation. The definition of OE still lacks uniformity. In particular, lesions that look clinically like erythroplakias, but are histopathologically diagnosed as squamous cell carcinomas are still sometimes called erythroplakias. The purpose of this study is to present demographic and clinicopathologic features of a series of OEs and clinically oral erythroplakia -like squamous cell carcinomas (OELSCC), to study their differences and to discuss the definition of OE.

METHODS

A multicenter retrospective case series of OEs and OELSCCs. Descriptive statistics were used to analyze the data.

RESULTS

11 cases of OEs and 9 cases of OELSCCs were identified. The mean age of the OE patients was 71 years and 72.7% were female, while the mean age of the OELSCC patients was 69 years, and all were female. 9% of the OE and 22% of the OELSCC patients had smoked or were current smokers. 72.7% of the OEs and 55.5% of OELSCCs were uniformly red lesions. 63.6% of the OE and 22% of the OELSCC patients had a previous diagnosis of oral lichenoid disease (OLD). The malignant transformation rate of OE was 9% in a mean of 73 months.

CONCLUSIONS

OE and OELSCC may arise de novo or in association with OLD. Tobacco and alcohol use were not prevalent in the present cases. The clinical features of OEs and OELSCC are similar, but symptoms, uneven surface and ulceration may be more common in OELSCCs than in OEs. Clinical recognition of OE is important since it may mimic other, more innocuous red lesions of the oral mucosa. The diagnosis of OE requires biopsy and preferably an excision. Clarification of the definition of OE would aid in clinical diagnostics.

Geroscience: Aging and Oral Health Research

Research in aging has significantly advanced; scientists are now able to identify interventions that slow the biologic aging processes (i.e., the "hallmarks of aging"), thus delaying the onset and progression of multiple diseases, including oral conditions. Presentations given during the 3-part session "Geroscience: Aging and Oral Health Research," held during the 2023 American Association for Dental, Oral, and Craniofacial Research meeting, are summarized in this publication. Speakers' topics spanned the translational research spectrum. Session 1 provided an overview of the geroscience and health span (disease-free and functional health throughout life) concepts. The common molecular mechanisms between oral cancer and aging were discussed, and research was presented that showed periodontal microflora as a potential factor in Alzheimer's disease progression. Session 2 focused on behavioral and social science aspects of aging and their oral health significance. The keynote provided evidence that loneliness and isolation can have major health effects. These social conditions, along with poor oral health, tooth loss, and cognitive decline, could potentially affect healthy eating ability and systemic health in older adults. Research could help elucidate the directions and pathways connecting these seemingly disparate conditions. Session 3 focused on the delivery of oral care in different settings and the many barriers to access care faced by older adults. Research is needed to identify and implement effective technology and strategies to improve access to dental care, including new delivery and financing mechanisms, workforce models, interprofessional provider education and practice, and use of big data from medical-dental integration of electronic health records. Research to improve the "oral health span," reduce oral health disparities, and increase health equity must be tackled at all levels from biologic pathways to social determinants of health and health policies.

High-Risk Human Papillomavirus in Patients with Oral Carcinoma and Oral Potentially Malignant Disorders in Serbia-A Pilot Study

Background and Objectives: Oral squamous cell carcinoma (OSCC) accounts for about 95% of oral cancers. It represents a serious public health problem due to the high degree of morbidity and mortality, as well as multifactorial etiology. Human papillomavirus (HPV) infection is a well-documented risk factor for oropharyngeal carcinoma, but its role in oral carcinogenesis is still debatable. Our aim was to investigate the differences in the prevalence of high-risk HPV genotypes (HR-HPV) in patients with OSCC and oral potentially malignant disorders (OPMD) from that of healthy subjects. Materials and Methods: A total of 90 subjects were included in the cross-sectional study and divided into three groups of 30 patients each: (1) patients with OSCC, (2) patients with OPMD, and (3) healthy subjects. We examined the presence of 12 HR-HPV genotypes in the obtained biological material (oral swabs) using real-time PCR. Results: One or more of the 12 tested HR-HPV genotypes were detected in 5/30 patients with OSCC and 2/30 with OPMD, whereas no healthy subjects were positive for any of the tested genotypes. There was a statistically significant difference in nodal involvement between HPV-positive and HPV-negative patients with OSCC. Conclusions: Oral HR-HPV was detected in patients with oral premalignant and malignant lesions but not in healthy individuals, suggesting a possible role in oral carcinogenesis. Broad HR-HPV panel testing could increase the sensitivity of risk assessment and screening for OSCC.

The Magic Triangle in Oral Potentially Malignant Disorders: Vitamin D, Vitamin D Receptor, and Malignancy

OPMDs (oral potentially malignant disorders) are a group of disorders affecting the oral mucosa that are characterized by aberrant cell proliferation and a higher risk of malignant transformation. Vitamin D (VitD) and its receptor (VDR) have been extensively studied for their potential contributions to the prevention and therapeutic management of various diseases and neoplastic conditions, including oral cancer. Observational studies suggest correlations between VitD deficiency and higher cancer risk, worse prognosis, and increased mortality rates. Interestingly, emerging data also suggest a link between VitD insufficiency and the onset or progression of OPMDs. Understanding the role of the VitD-VDR axis not only in established oral tumors but also in OPMDs might thus enable early detection and prevention of malignant transformation. With this article, we want to provide an overview of current knowledge about OPMDs and VitD and investigate their potential association and ramifications for clinical management of OPMDs.

Influence of an oral health promotion program on the evolution of dental status in New Caledonia: A focus on health inequities

New Caledonia is a sui generis collectivity of overseas France situated in the south Pacific Ocean. Geographical and social inequalities are superimposed on ethnic disparities with high prevalence of chronic diseases such as oral diseases. In 2012, the health agency has evaluated the children's health status. Then, an oral health promotion program was developed in 2014. Another study was conducted in 2019 in New Caledonia to appreciate the evolution of children's oral health. A sample of 488 9-years-old children was randomly selected. Dental status was clinically recorded, families and children answered questionnaires about oral health determinants. The methodology (sampling, study variables…) was similar to the one used in the 2012 study. Multivariate mixed-models were conducted to compare 2012 and 2019 dental status and to explore the determinants of caries experience in 2019. Results indicated that caries prevalence and experience decreased between 2012 and 2019, with nonetheless various trends depending on the province or type of indexes. The number of carious lesions (d3t + D3T) in 2019 was used as an outcome variable in four models. Model 1 integrated social variables; ethnicity was found to be the only significant determinant. Model 2 was related to oral health care; participation in the program & and access to oral health care was found to be significant. For oral health behaviours (model 3), tooth brushing frequency and consumption of sugary snacks were significant risk factors. In a final model with significant variables from the previous models, ethnicity, accessibility of oral health care, number of sealed molars, consumption of sugary snacks remained explanatory factors. Five years after the implementation of the oral health promotion program, positive changes in oral health have been observed. However, health equity is still an issue with varying health status depending on ethnicity, behavioural factors and accessibility to oral health care.

[Oral health and hygiene behavior in chronic renal failure patients]

PURPOSE

To investigate the oral health and hygiene behavior of chronic renal failure(CRF) patients in Shenzhen, so as to provide basis for formulating education for them.

METHODS

The history of renal failure, oral health status and oral health care behavior of 336 patients with chronic renal failure(CRF) in the hemodialysis center of Shenzhen Second People's Hospital were investigated by questionnaire and oral examinations.

RESULTS

At an average, dialysis was required for 3.2 years. The main cause of renal failure was glomerulonephritis in 49.11% of patients, hypertensive kidney lesion in 19.35% and diabetic nephropathy in 15.77% of patients; 77.8% of them kept brushing teeth two or more than two times every day; 72.9% patients suffered from oral problems such as toothache in recent 12 months. The rate of visiting a dentist when having complaints was 21.7%.

CONCLUSIONS

The state of oral health of CRF is worse than the general population of comparable age in China, while their hygiene behavior is better than the corresponding reference general population. However, their consciousness of dental treatment is poor. Therefore, health education for CRF patients should include knowledge about oral diseases complicated with CRF and correct medical philosophy.

Progression to malignancy in oral potentially malignant disorders: a retrospective study of 5,036 patients in Ontario, Canada

OBJECTIVES

Determine the rate of malignant transformation (MT) of oral potentially malignant disorders (OPMDs) and risk factors for transformation.

STUDY DESIGN

The OPMD database (2001-2015) from 2 biopsy services in Ontario, Canada, was linked to the Ontario Cancer Registry to determine the rate of progression to oral squamous cell carcinoma (OSCC). Clinical and histologic features of progressed and non-progressed cases were compared to determine risk factors for progression.

RESULTS

The MT rate was 6.4% (322/5,036 cases). The mean time for cancer development was 51.2 months. 33.6% of cases (107/322) progressed after over 60 months. The risk of cancer increased with age and was higher in non-smokers. The MT rate was highest in the tongue (11.4%), followed by the floor of mouth (7.1%) and gingiva (6.5%). Histologic grade was associated with progression to cancer (P < .0001). Atypical verrucous-papillary lesions with no or mild dysplasia predominantly affected older patients' gingiva, and the progression rate was significantly higher than conventional mild dysplasia (9.2% vs 3.2%, P = .0002).

CONCLUSIONS

Our population-based retrospective study showed that <10% of OPMDs progressed to cancer, which could take many years. Atypical papillary-verrucous proliferation without high-grade dysplasia is a subtype of OPMD requiring further study.

Dental implants for patients with oral mucosal diseases: A narrative review and clinical guidance

Oral mucosal diseases are a group of conditions that affect the oral mucosa with variable severity and include recurrent aphthous stomatitis (RAS), oral lichen planus (OLP), pemphigus vulgaris (PV), mucous membrane pemphigoid (MMP), and systemic lupus erythematosus (SLE). These may manifest clinically as painful oral ulcerations, reticulations and/or erosions, with differences between each. Management protocols often include initial topical and/or systemic corticosteroid (CS) therapy to control the patient's acute symptoms, followed by CS-sparing agents for long-term maintenance therapy. Patients with oral mucosal diseases often require dental implants to replace missing teeth. However, data on potential complications and success rates for these cases is still lacking. Considering the steady increase in the incidence of immune-related systemic conditions in the general population globally, dentists are expected to have the needed knowledge and ability to safely place dental implants in this group of patients. Therefore, this review aims to discuss the underlying pathogeneses of common oral mucosal diseases, clinical presentations, best practice approaches, and recommendations for the placement of dental implants in patients with similar conditions.

Head and neck exam practices of dental professionals

OBJECTIVE

Periodic examination of the head and neck includes screening for oral cancer, which is largely performed in dental offices by vigilant oral healthcare providers. The aim of this study was to assess practice patterns among Virginia dentists in performing head and neck exams and the referral rates of biopsies after completion of head and neck exams. We hypothesized that not all dentists perform head and neck exams and there is a difference between dentists who refer patients for a biopsy and those that perform biopsies.

METHODS

General dentists and dental specialists who are members of the Virginia Dental Association were invited to participate in a cross-sectional survey study through REDCap to self-report their head and neck exam protocols.

RESULTS

A total of 224 providers completed the survey. The majority of respondents were general dentists with more than 20 years in practice, who practice in a private setting, and see more than 10 patients in a day. All respondents stated they perform intraoral examinations, but 10 respondents stated they do not perform extraoral examinations. Nearly a third of respondents reported doing their own biopsies.

CONCLUSIONS

Although only 8.5% of oral healthcare providers in Virginia responded to our survey, respondents are following the 2017 ADA good practice statement by providing their patients with head and neck exams to screen for oral cancer. Additional education pertaining to extraoral anatomy, malignant transformation of oral potentially malignant disorders, and pathology procedures may be helpful to clinicians.

Periodontitis in individuals with few remaining teeth and a high gingival bleeding index increases the probability of dyslipidemia

BACKGROUND

Dyslipidemia, a silent multifactorial condition, is characterized by changes in blood lipid levels, affecting all socioeconomic strata, increasing the risk for atherosclerotic diseases. This study investigated whether there is an association between dyslipidemia and the combined exposure of periodontitis plus the number of remaining teeth, gingival bleeding, or caries.

METHODS

A two-center cross-sectional study was conducted involving 1270 individuals, with a minimum age of 18 years. Socioeconomic and demographic data, health conditions, lifestyle parameters, and anthropometric, biochemical, and oral clinical examinations were performed. The exposures considered were the presence of periodontitis, dental caries, number of remaining teeth, and gingival bleeding. The outcome was dyslipidemia as defined by the Brazilian Guidelines on Dyslipidemia and Prevention of Atherosclerosis. The combined associations between periodontitis plus other oral health conditions and dyslipidemia were estimated using confounder-adjusted prevalence ratios (PRsingle , PRmultiple , for single and multiple covariable adjustments) with 95% confidence intervals (95% CIs), in a Poisson regression model with robust variance.

RESULTS

The occurrence of dyslipidemia was 70.1% and periodontitis was 84.1%. A positive association between periodontitis and dyslipidemia existed: PRsingle  = 1.13; 95% CI: 1.01-1.26. Combined exposure of periodontitis plus <11 remaining teeth (PRmultiple  = 1.23; 95% CI: 1.05-1.43), as well as combined exposure of periodontitis plus ≥10% gingival bleeding and <11 remaining teeth (PRmultiple  = 1.22; 95% CI: 1.03-1.44), represented greater probabilities of 23% and 22% of individuals having a diagnosis of dyslipidemia.

CONCLUSION

Periodontitis combined with fewer than 11 teeth doubled the likelihood of being diagnosed with dyslipidemia.

Treatment strategies for periodontitis patients with systemic disease

Periodontitis is a chronic inflammatory disease that destroys the integrity of tooth-supporting tissue. Periodontitis is listed as a major oral disease by the World Health Organization and is a public-health problem affecting global oral and systemic health. The fourth national oral health epidemiological survey has revealed that periodontitis is one of the most common oral problems in China. With the development of science and medicine, increased attention is being paid to the importance of oral health and its influence on general health. Accordingly, stomatologists are required to master more relevant information on clinical diagnosis and treatment, as well as to pay more attention to the diagnosis and treatment methods of patients with different systemic diseases. This article expounds the diagnosis and treatment strategy of patients with systemic disease periodontitis. We aimed to help stomatologists make more reasonable diagnosis and treatment decisions.

An Appreciation of a Giant in Orofacial Sciences Research-John Greenspan

Professor John S. Greenspan died on March 31, 2023. He was a renowned and accomplished academic, dentist/scientist, pathologist, and administrator who made sustained and significant international impacts on numerous fields over half a century. John was arguably best known for his work with his wife, Dr. Deborah Greenspan, on the oral aspects of AIDS and the role of viruses in oral epithelial and salivary gland lesions. He had a lifelong interest in Sjögren's syndrome, culminating in the leadership of the Sjögren's International Collaborative Clinical Alliance. He was also widely recognized as one of the leading investigators into the understanding of oral mucosal diseases, including recurrent aphthous stomatitis. He and his colleagues' major contributions to HIV research and care included the discovery of the oral lesion "hairy leukoplakia," its etiological association with Epstein-Barr virus, and other oral lesions in the natural history of HIV disease. In recent years, John turned his attention to global oral health inequalities, helping to establish the International Association for Dental Research's Global Oral Health Inequalities Research Network and serving as its first president. He led many organizations with humble authority, knowledge, wit, and wisdom and mentored colleagues from all over the world, especially from lower- and middle-income countries. John leaves a very special legacy based on example and scientific curiosity, and his work has not only made a lasting impact on his colleagues but also translated to abiding benefit for patients.

Dementia and the history of disease in older adults in community

INTRODUCTION

Many studies have revealed the effect of medical history on dementia. The aim of this study was to explore the relationship between the history of disease and onset of dementia.

METHODS

This was a multi-center, cross-sectional study, with 2595 older adults enrolled. The onset of dementia was evaluated with Revised Hasegawa Dementia Scale (HDS-R). The diagnosed diseases after the age of 40 of the participants were investigated, including respiratory system diseases, digestive system diseases, cardiovascular diseases, endocrine disorders, genitourinary system diseases, nervous system disease, sensory system diseases, dental/oral diseases, bone/joint diseases and mental illnesses.

RESULTS

Data of 2458 older adults were analyzed. Univariate analysis showed that diabetes, thyroid disease, mental illness, hearing loss, stroke, dental/oral disease, Denture use, fracture/osteoporosis, kidney disease and number of diseases were risk factors for dementia. After controlling for demographic sociological variables, diabetes, dental/oral disease, and denture use were independent risk factors for dementia. Thyroid disease (P = 0.313), mental illnesses (P = 0.067), hearing loss (P = 0.595), stroke (P = 0.538), fractures/osteoporosis (P = 0.069), kidney disease (P = 0.168) were no longer significant to dementia.

CONCLUSION

Diabetes, dental/oral disease and denture use were main risk factors for dementia.

Burnout: A predictor of oral health impact profile among Nigerian early career doctors

There have been reported association of oral health disorders with burnout, stress, and mental health. Arguably, with these reported associations, and the current prevalence of burnout amongst Nigerian doctors, exploring the role of burnout on oral health amongst Nigerian doctors is timely. This study aims to determine the relationship between burnout and oral health-related quality of life amongst Early Career Doctors (ECDs) in Nigeria, while also identifying the role other possible predictors plays in this relationship. This was a cross-sectional study conducted amongst Nigerian ECDs as part of Challenges of Residency Training in Nigeria (CHARTING) II project. A total of 632 ECDs were recruited across thirty-one tertiary hospitals in the 6 geopolitical zones of the country using a multistage cluster sampling technique. A self-administered paper-based semi-structured questionnaire was given to each participant that consented. The tools used to assess burnout and Oral health-related quality of life (OHRQoL) were Copenhagen Burnout Inventory (CBI) and Oral Health Impact Profile (OHIP-14) respectively. Independent samples T-test, ANOVA and Multiple linear regression were used to draw inferences from the data collected. Overall mean OHIP-14 score of all participants was 11.12 (±9.23). The scores for the 3 dimensions of burnout were below 50% with CBI-Personal Burnout having the highest score of 49.96 (±19.15). Significant positive correlations (p < 0.001) were found between OHIP-14 and all the dimensions of burnout, as the burnout scores were increasing, there was a corresponding increase in the OHIP scores thus poorer OHRQoL. The regression model shows that the predictors of OHIP were CBI-PB (p = 0.003), use of fluoride paste (p = 0.039), use of tobacco (p = 0.005) and being a denture user (p = 0.047). This study shows a positive correlation between burnout and OHIP of ECDs. We found that as burnout was increasing, OHIP increased thus implying poorer oral health related quality of life amongst ECDs. The use of fluoride toothpaste, tobacco and denture are other factors we found that could affect the OHIP of ECDs.

Evaluation of crystallization patterns in oral potentially malignant disorders and oral malignancies: A prospective study

Background

Oral cancers are often detected at late stages, and patients usually had a 50% chance of a 5-year survival rate. Oral cancer usually has an early precancerous stage before its actual malignant transformation. Although there are various approaches to diagnose the early stages of cancer, there is one less explored, cost-effective, and simple technique known as the crystallization test. The aim of the study was to evaluate the crystallization patterns in tobacco users, oral potentially malignant disorders (OPMDs), and oral malignancies.

Materials and Methods

Fifteen patients with oral malignancies, 15 patients with oral potentially malignant disorders, 15 tobacco users, and 15 healthy individuals participated in the crystallization test. Single blood drop was used to perform this test and the obtained crystal patterns were analyzed.

Results

This test had a sensitivity of 93.3%, 80.0%, and 20.0% for oral malignancies, oral Potentially Malignant Disorders (PMDs), and tobacco users, respectively. Chi-square analysis revealed a highly significant transverse form between OPMDs and oral malignancies (P < 0.05).

Conclusion

Crystallization test was found to be a sensitive, reliable, economical, and less invasive procedure for screening of oral PMDs and oral malignancies under strictly maintained physical conditions.

Oral health equity for rural communities: where are we now and where can we go from here?

Oral health is embedded in overall health and contributes to physical, social and mental wellbeing. Most diseases are preventable, and yet, oral diseases pose a significant public health problem and an economic burden globally. Poor oral health is a risk factor for certain systemic diseases, such as cardiovascular disease, diabetes and lung pathologies. Rural populations are disproportionately affected by oral disease, with higher levels of periodontal disease, caries and the loss of teeth. These issues are worsened by barriers in access to oral healthcare services and minimal promotion of healthy behaviours in rural communities. Certain interventions, including mobile dental clinics, teledentistry, dental outreach camps and educational initiatives, have been successful in addressing rural challenges. Policies and action plans should be considered by public health officials to reduce the disparities in oral health among rural communities, reduce the overall burden of oral health and promote health equity.

Characterization of the oral microbiota among middle-aged men with and without human papillomavirus infection

OBJECTIVES

To characterize the oral microbiota among middle-aged men and identify differences between men with a prevalent oral high-risk (oncogenic) HPV infection and those without.

MATERIALS AND METHODS

This was a case-control study nested within a prospective screening study for HPV-related cancers among middle-aged men. 16S rRNA sequencing was used to characterize the oral microbiota and the cobas HPV Test was used to detect presence of oral high-risk HPV types. We determined the overall composition of the oral microbiota and assessed differences in relative abundance of bacterial taxa as well as alpha and beta diversity among men with a prevalent oral high-risk HPV infection compared to men who were HPV-negative.

RESULTS

Among 13 high-risk HPV-positive and 30 HPV-negative men, we found significant differences in beta diversity but not alpha diversity. Fretibacterium, F0058, Kingella, Treponema, and Prevotella were more abundant among the high-risk HPV-positive men while Neisseria and Lactobacillus were more abundant among the HPV-negative men.

CONCLUSION

This study adds to the evidence that the oral microbiota varies according to oral HPV infection status and may be associated with the natural history of oral HPV infection.

Acetic acid versus toluidine blue as screening tools for oral potentially malignant disorders

Background

Diagnostic adjuncts such as toluidine blue have been investigated as screening tools that improve visual examination of potentially malignant disorders (PMD) and oral cancer. Acetic acid has been reported to be of value in the early detection of cervical cancers. This study assessed the utility of 5% acetic acid as a diagnostic adjunct in oral PMD and compared the accuracy of acetic acid with toluidine blue in the detection of dysplastic PMD and high-risk lesions.

Materials and Methods

This cross-sectional study was conducted at a dental hospital in a rural setting. Thirty-one patients with oral PMD formed the study group. Five percent acetic acid was applied to the lesions, followed by toluidine blue application and biopsy. Sensitivity, specificity, and positive and negative predictive values were computed considering true positives as stain uptake in dysplastic and high-risk PMD.

Results

The sensitivity, specificity, and positive and negative predictive values of acetic acid for identifying dysplastic or malignant lesions were 100%, 13.3%, 51.2%, and 100%, respectively, and that for toluidine blue were 75%, 100%, 100%, and 78.9%, respectively. The corresponding values for identifying high-risk PMD (lesions with moderate and severe dysplasia) using acetic acid were 100%, 9.1%, 25.9%, and 100%, respectively, and for toluidine blue were 85.7%, 81.8%, 60%, and 94.7%, respectively.

Conclusion

The utility of acetic acid in detecting dysplasia and high-risk PMD is severely limited due to its poor specificity. Compared with acetic acid, toluidine blue is a superior screening tool.

Clinical and Subjective Oral Health Status of Care Home Residents in Europe: A Systematic Review

OBJECTIVE

Several studies demonstrated the poor oral health of care home residents in Europe but there is no systematic overview of the relevant literature. The objective of this study was to systematically review the evidence on the clinical and subjective oral health outcomes of care home residents in Europe.

DESIGN

The study design is a systematic review.

METHODS AND PARTICIPANTS

All included publications presented data on clinical and/or subjective oral health outcomes in care home residents in Europe with no restrictions for language or study design. MEDLINE, Embase, and CINAHL were searched, including publications from January 2010 onward. Data extraction and quality assessment (Qualsyst tool) was performed by 2 researchers independently. Findings were synthesized narratively, lack in data homogeneity restricted the relevance of a meta-analysis.

RESULTS

Eighty-three papers from 18 countries were included in the systematic review, with a sample size ranging from 39 to 92,827 participants. Their mean age was older than 80 years. The residents had few natural teeth, with fewer than a third a functional natural dentition. Removable dentures were present in half to 80% of residents. A high prevalence of dental caries was reported. Oral hygiene was insufficient, for both natural teeth and removable dentures. Few residents had a healthy periodontium. Clinical treatment needs were found in most residents. Perceived treatment needs were high with at least one-third of care home residents reporting a need for care due to poor oral health. A fifth to half of the residents reported negative impacts of their oral condition on their everyday lives.

CONCLUSION AND IMPLICATIONS

This systematic review clearly highlights the poor oral health and high burden of oral conditions among care home residents across Europe, irrespective of country or health care system. There is need for substantial policy actions to improve oral health in care homes.

Prevalence and determinants of oral potentially malignant disorders in rural areas of South India

Purpose

Oral potentially malignant disorders are associated with a risk of undergoing malignant transformation and a concomitant increase in morbidity and mortality. Moreover, epidemiological studies, especially from rural areas, are important in assessing their prevalence and the identification of determinants of these disorders so that preventive strategies can be employed in tackling them.

Methods

Cross-sectional descriptive study was conducted based on guidelines of the World Health Organization's Guide Epidemiology and Diagnosis of Oral Mucosal Disease and Conditions 1995 in rural areas of south India.

Results

Prevalence of oral potentially malignant disorders (OPMDs) in the studied population was 13.28%, with oral submucous fibrosis (OSMF) accounting to 6.21% and erythroplakia at 1.3%. Regression analysis revealed, age 40-54 years (odds ratio [OR] = 3.8, confidence interval [CI] at 95%-1.5-4.0, P < 0.05), lower socioeconomic groups (OR = 2.1, CI at 95%-1.4-3.1, P < 0.05), habits (OR = 3.2, CI at 95%-1.9-3.8, P < 0.05), smoke form of tobacco-beedi (OR = 2.5, CI at 95%-1.6-2.8, P < 0.05), smokeless form of tobacco-areca nut lime and leaf and tobacco (OR = 3.1, CI at 95%-1.9-3.4, P < 0.05) to be the possible determinants for OPMDs.

Conclusions

The overall prevalence of OPMDs in the studied population was 13.28%. The most common OPMDs were OSMF. Identified determinants were age, socioeconomic group, ethnicity, diet, body mass index, and associated harmful habits.
