The dental health of people with schizophrenia

Altered oral health and microbiota in drug-free patients with schizophrenia

BACKGROUND

The oral microbiota is associated with neuro-psychiatric disorders. However, there is presently inadequate comprehension regarding the correlation between schizophrenia and the oral microbiota. Moreover, patients with schizophrenia frequently exhibit poor oral health, potentially influencing research outcomes. Therefore, this study aims to investigate changes in the oral microbiota and oral health status in drug-free schizophrenia patients.

METHODS

Oral microbiota samples were collected from 50 drug-free patients with schizophrenia and 50 healthy controls (HCs). The downstream microbiota analysis was based on Illumina sequencing of the V3-V4 hypervariable region of the 16 S rRNA gene.

RESULTS

The alpha diversity of SCZ group is increased, such as the Shannon index (p < 0.001) and Simpson index (p = 0.004), while the community structure also displays variance compared to the HC group (p < 0.001). Key discriminative taxa were found in LEfSe analysis, including the phyla Fusobacteriota, Firmicutes, and Actinobacteriota. The differential taxa and microbial functions showed a strong correlation with clinical oral conditions. Further analysis demonstrated that models based on the entire oral microbiota effectively distinguished SCZ patients from HC (AUC = 0.97).

CONCLUSIONS

The significant changes in the microbiota of Drug-free SCZ patients appear to be closely associated with the poor oral environment.

Mind the gap: an administrative data analysis of dental treatment outcomes and severe mental illness

BACKGROUND

Oral health of people with severe mental illness (SMI) remains an important public health issue, despite evidence pointing suboptimal dental health outcomes in this population.

AIMS

We test the hypotheses that individuals with SMI have lower contact with dental services and higher levels of fillings and extractions. We also examine effect modification by age-group.

METHODS

We used linked administrative data from general practitioner (GP), hospital and dental records to examine dental service use and treatments (extractions, fillings, crowns and x-rays) among the Northern Ireland hospital population between January 2015 and November 2019 (N = 798,564).

RESULTS

After adjusting for available socio-demographic characteristics, analysis indicated lower levels of dental service use (OR = 0.80, 95% CI = 0.77, 0.84), including lower likelihood of fillings (OR = 0.81, 0.77, 0.84) and x-rays (OR = 0.77, 0.74, 0.81), but higher levels of extractions (OR = 1.23, 1.18, 1.29) among patients with SMI. We also found effect modification by age-group, with older individuals with SMI less likely to have each of the four dental treatments.

CONCLUSIONS

We suggest that in the general area of physical healthcare for people with SMI, oral healthcare is neglected. There is a need for improved understanding of the barriers to routine care and treatment, and development of psychoeducational interventions.

Postoperative evaluation of special needs and healthy patients with endodontic treatment under general anesthesia: a retrospective research

BACKGROUND

This retrospective clinical study was undertaken to comparatively evaluate the number of restorative treatments, endodontic treatments, and tooth extractions performed for patients under general anesthesia due to dental anxiety or special needs between 2015 and 2022 and to examine the pain, bleeding, nausea, and vomiting data of those patients.

METHODS

In total, 1165 patients underwent dental treatment under general anesthesia in the faculty hospital. Those under the age of 15 and with no endodontic procedure planned (n = 918) were excluded, followed by those with incomplete data (n = 25) and those without endodontic treatment (n = 25). Patients who underwent at least one endodontic treatment were finally included in the study (n = 184). Patients were divided into two groups: healthy and with special needs. Dental treatments were recorded as endodontic, restorative, and teeth extractions. Endodontic treatments were classified according to the tooth type (premolar, molar, and incisors). The composite restorations were classified as anterior, occlusal (O), occluso-distal (OD) or occluso-mesial (OM), and mesio-occluso-distal (MOD) restorations and patients' post-treatment pain, nausea, vomiting, and bleeding were recorded. The data were analyzed statistically.

RESULTS

Among the 184 patients included in the study, 70 (38%) were healthy, and 114 (62%) had special needs. Postoperative bleeding was observed more in patients with special needs (χ2 = 4.189, p < 0.05), whereas pain was observed more in healthy patients (U = 2922.00, p < 0.05). While the number of anterior, O, and MOD restorations was higher in patients with special needs, the number of OD or OM restorations was higher in healthy patients (χ2 = 74.877, p < 0.05).

CONCLUSIONS

Patients with special needs undergo a greater number of restorative treatments compared to control patients, which may be associated with the inadequate oral hygiene care of such patients. However, restorative treatment is mostly indicated for such patients in our faculty hospital, which may indicate that a conservative approach is taken. Additionally, the finding that postoperative bleeding was more severe in this group of patients compared to the control group in this study may emphasize the need to consider more possible complications after general anesthesia in these patients.

Decreased oral function in Japanese inpatients with schizophrenia

AIM

Oral function in patients with schizophrenia has not been well-characterized. To address this, we performed a cross-sectional study of oral function in Japanese inpatients with schizophrenia.

METHODS

We measured oral function, including occlusal force, tongue-lip motor function, tongue pressure, and masticatory function in 130 Japanese inpatients with schizophrenia. We then compared the frequency of clinical signs of oral hypofunction among 63 non-elderly and 67 elderly inpatients with schizophrenia, as well as data from 98 elderly control participants from a previous Japanese study.

RESULTS

The frequency of reduced occlusal force was significantly higher in the elderly inpatients (76.2%) than in the non-elderly inpatients (43.9%) and elderly controls (43.9%). The frequency of decreased tongue-lip motor function in non-elderly inpatients (96.8%) and elderly inpatients (97.0%) was significantly higher than that in elderly controls (56.1%). The frequency of decreased tongue pressure in non-elderly inpatients (66.1%) and elderly inpatients (80.7%) was significantly higher than that in elderly controls (43.9%). Finally, the frequency of decreased masticatory function was highest in elderly inpatients (76.5%), followed by non-elderly inpatients (54.8%) and elderly controls (15.3%).

CONCLUSION

Oral function was decreased in both non-elderly and elderly Japanese inpatients with schizophrenia compared with elderly controls.

The Development of an Oral Health Nursing Tool for Patients with a Psychotic Disorder: A Human-Centred Design with a Feasibility Test

Patients with psychotic disorders frequently report oral health problems, while mental health nurses (MHNs) seem not to be fully aware of these problems and the risk factors. Therefore, this study aimed to develop supportive tools for MHNs regarding oral health to increase sensitisation among MHNs and provide MHNs with the knowledge to recognise (potential) oral health problems in patients with a psychotic disorder. We used a human-centred design in which the user, MHNs and experts by experience were placed at the centre of the research process. Problems and needs in MHNs working with patients with a psychotic disorder were addressed. To identify key issues of problems as well as needs in terms of resources, we started with focus groups (n = 9). We analysed the data thematically based on the context of patients and MHNs in practice regarding oral health, preferred oral health tools focused on MHNs, and the intended outcomes of tools. A multi-criteria decision matrix was developed and analysed (n = 9) to identify the most optimal and viable solution based on established criteria and issues that are prevalent in the work of MHNs. The most promising result was the development of a brochure with an awareness screener. The brochure with the awareness screener was developed as a low-fidelity prototype for MHNs regarding oral health in patients with a psychotic disorder based on the latest scientific evidence. After testing it, the feasibility was tested through semi-structured interviews (n = 19). MHNs and experts by experience were satisfied with the tool and provided recommendations for adjustments to the content. Significant augmentations to the brochure included a clinical lesson and a toothbrush with toothpaste for patients. We can conclude that a brochure with an awareness screener is feasible for MHNs. Future steps aiming to further refine and optimise care processes for oral health tools in MHNs should take refining eligibility criteria for psychiatric populations and the language level of the target group of a tool into account.

Periodontal disease in people with a history of psychosis: Results from the UK biobank population-based study

OBJECTIVES

To test the hypotheses that: (1) Prevalence of periodontal disease would be higher in people with a history of psychosis when compared to the general population and (2) Demographic, life-style related factors and co-morbid medical conditions would predict periodontal disease in people experiencing psychosis.

METHODS

The authors performed cross-sectional analysis of baseline data from the UK Biobank study (2007-2010), identifying cases with psychosis using clinical diagnosis, antipsychotic medication, and self-report. Demographic (age, gender, ethnicity, socioeconomic status), lifestyle-related(BMI, blood pressure, smoking and alcohol intake, physical activity) and physical co-morbidities (cancer, cardiovascular, respiratory, inflammatory disease and metabolic conditions) were included as potential risk factors for periodontal disease among people with a history of psychosis using logistic regression analyses. The analysis sample included 502,505 participants.

RESULTS

Risk of periodontal disease was higher in people with psychosis, regardless of how cases were identified. Patients with a clinical diagnosis had the highest proportion of periodontal disease compared to the general population (21.3% vs. 14.8%, prevalence ratio 1.40, 95% CI: 1.26-1.56). Older and female cases were more likely to experience periodontal disease. Lifestyle factors (smoking) and comorbidities (cardiovascular, cancer or respiratory disease) were associated with periodontal disease among people with a history of psychosis.

CONCLUSIONS

The findings suggest that periodontal disease is more common in people with a history of psychosis, compared to the general population. Prevention and early diagnosis of periodontal disease should be a priority for oral health promotion programmes, which should also address modifiable risk factors like smoking which also contribute to co-morbid systemic disease.

A Human-Centered Design Approach to Develop Oral Health Nursing Interventions in Patients with a Psychotic Disorder

In mental health, oral health is often given little attention. Mental health nurses (MHNs) are professionally the appropriate target group to support maintaining and increasing oral health. We aimed to develop and validate personas that reflect the attitudes and needs of MHNs regarding oral health in patients with a psychotic disorder. We used a human-centered design with contextual interviews (n = 10) to address the key issues of the problems and needs of MHNs working with patients with a psychotic disorder. We analyzed the data thematically and reflected on insights into unique personas, which were then validated by conducting semi-structured interviews (n = 19) and member checking. Four personas were found based on attitudes and perspectives, barriers, needs, suggestions for interventions, and site conditions regarding practicing oral care in this patient group. Our findings were as follows: the attitudes and perspectives differed from not feeling any responsibility to a holistic obligation, including oral health; suggestions for interventions for MHNs ranged from interventions focusing on improving skills and knowledge to using practical tools; most MHNs recognized themselves within a persona that had a holistic obligation that included oral health; in addition, the MHNs indicated that they considered the issue of oral health in this patient group important, but, in practice, took little responsibility for that role. These findings suggest that a toolkit with interventions for MHNs that are tailored to the personas that emerged from our research should be developed by MHNs in co-creation with designers. The differences between the perceived role and MHNs' practice in oral health highlighted the need for role clarification and professional leadership of MHNs regarding oral health, which should be considered when developing interventions.

Mental health and periodontal and peri-implant diseases

Mental health disorders, particularly depression and anxiety, affect a significant number of the global population. Several pathophysiological pathways for these disorders have been identified, including the hypothalamic-pituitary-adrenal axis, autonomic nervous system, and the immune system. In addition, life events, environmental factors, and lifestyle affect the onset, progression, and recurrence of mental health disorders. These may all overlap with periodontal and/or peri-implant disease. Mental health disorders are associated with more severe periodontal disease and, in some cases, poorer healing outcomes to nonsurgical periodontal therapy. They can result in behavior modification, such as poor oral hygiene practices, tobacco smoking, and alcohol abuse, which are also risk factors for periodontal disease and, therefore, may have a contributory effect. Stress has immunomodulatory effects regulating immune cell numbers and function, as well as proinflammatory cytokine production. Stress markers such as cortisol and catecholamines may modulate periodontal bacterial growth and the expression of virulence factors. Stress and some mental health disorders are accompanied by a low-grade chronic inflammation that may be involved in their relationship with periodontal disease and vice versa. Although the gut microbiome interacting with the central nervous system (gut-brain axis) is thought to play a significant role in mental illness, less is understood about the role of the oral microbiome. The evidence for mental health disorders on implant outcomes is lacking, but may mainly be through behaviourial changes. Through lack of compliance withoral hygiene and maintenance visits, peri-implant health can be affected. Increased smoking and risk of periodontal disease may also affect implant outcomes. Selective serotonin reuptake inhibitors have been linked with higher implant failure. They have an anabolic effect on bone, reducing turnover, which could account for the increased loss.

A study of the association between psychiatric symptoms and oral health outcomes in a population-based birth cohort at 30-year-old follow-up

OBJECTIVE

Most studies of the association between psychiatric disorders and poor oral health have been conducted in clinical settings. Where available, data from community surveys have generally been cross-sectional or considered anxiety and depression as a consequence of poor oral health, not the other way round. This study therefore used a birth cohort to assess the association of mental health, measured both cross-sectionally and longitudinally, and oral health at 30-year follow-up.

METHODS

There were 2456 adults with data on dental outcomes and oral health care at 30-year follow-up. Psychiatric morbidity was measured at both 21- and 30-year follow-up using standardised instruments including the Centre for Epidemiological Studies-Depression (CES-D) scale and Composite International Diagnostic Interview (CIDI).

RESULTS

At follow-up, 850 participants (34.6%) had undergone a dental extraction for infection or decay, and 810 had experienced significant dental pain over their lifetime. One third had not visited a dental clinic in the previous two years and 40% failed to brush their teeth at least twice daily. On adjusted analyses, dental extraction and pain were significantly associated with psychiatric morbidity cross-sectionally at 30-year follow-up and also longitudinally when psychiatric symptoms were present at both 21 and 30 years old. Several cross-sectional measures of psychiatric morbidity were also associated with frequency of tooth brushing. There were no associations with dental clinic visits.

CONCLUSIONS

The study demonstrates there are associations between oral and mental health, which are not limited to clinical settings, but were observed at a population level.

Risk factors and oral health-related quality of life: A case-control comparison between patients after a first-episode psychosis and people from general population

WHAT IS KNOWN ON THE SUBJECT?: Oral health consists of more than having good teeth; it is an important factor in general health and well-being. Despite its importance, oral health care is still largely overlooked in mental health nursing. There is no research available about oral health risk factors and OHRQoL in patients diagnosed with a psychotic disorder with a psychotic disorder (first-episode). WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This study provides insight into the severity of the problem. It demonstrates the differences in risk factors and OHRQoL between patients diagnosed with a psychotic disorder (first-episode) and the general population. A negative impact on OHRQoL is more prevalent in patients diagnosed with a psychotic disorder (first-episode) (14.8%) compared to the general population (1.8%). Patients diagnosed with a psychotic disorder (first-episode) have a considerable increase in odds for low OHRQoL compared to the general population, as demonstrated by the odds ratio of 9.45, which supports the importance of preventive oral health interventions in this group. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The findings highlight the need for oral health interventions in patients diagnosed with a psychotic disorder (first-episode). Mental health nurses, as one of the main health professionals supporting the health of patients diagnosed with a mental health disorder, can support oral health (e.g. assess oral health in somatic screening, motivate patients, provide oral health education to increase awareness of risk factors, integration of oral healthcare services) all in order to improve the OHRQoL. ABSTRACT: Introduction No research is available about the oral health risk factors and oral health-related quality of life (OHRQoL) in patients diagnosed with a psychotic disorder. Aim To compare oral health risk factors and OHRQoL in patients diagnosed with a psychotic disorder (first-episode) to people with no history of psychotic disorder. Method A case-control comparison (1:2) multivariable linear regression analysis and an estimation of prevalence of impact on OHRQoL. Results Patients diagnosed with a psychotic disorder (first-episode) have lower OHRQoL with more associated risk factors. Of the patients diagnosed with a psychotic disorder (first-episode), 14.8% reported a negative impact on OHRQoL, higher than the prevalence of 1.8% found in people from the general population. Discussion The high prevalence rate of a negative impact on OHRQoL in patients diagnosed with a psychotic disorder (first-episode) shows the importance of acting at an early stage to prevent a worse outcome. Implications for practice The findings highlight the need for oral health interventions in patients diagnosed with a psychotic disorder (first-episode). Mental health nurses, as one of the main health professionals supporting the health of patients diagnosed with a mental health disorder, can support oral health (e.g. assess oral health in somatic screening) in order to improve the OHRQoL.

An examination of predisposing and enabling factors that predict dental utilization among individuals with serious mental illness in Detroit, Michigan

OBJECTIVES

This study evaluated which predisposing and enabling factors prospectively predicted dental utilization over 6 months among people with serious mental illness.

METHODS

A sample of individuals with serious mental illness (86.3% African American; 97.4% with public health insurance) was recruited from community mental health centres in Detroit, Michigan, and responded to questionnaires at baseline and at least one follow-up visit at 3 or 6 months (N = 190). Baseline assessments included demographic and clinical information, established measures of health literacy, health insurance literacy, stigma related to mental illness, experiences of racial discrimination and medical mistrust. Insurance coverage for dental care and the availability of dental services at the participants' mental health centres was recorded. At follow-up visits, participants reported healthcare utilization, including dental and primary care, since baseline.

RESULTS

Three factors emerged as meaningful predictors of having a dental visit in bivariate and multivariate analyses: more medical comorbidities and dental care co-located with mental health care predicted increased likelihood of a dental visit, whereas having experienced racial discrimination in a medical setting predicted lower odds of having a dental visit in the follow-up period. Co-location of dental care with mental health care was the strongest predictor of having a dental visit.

CONCLUSIONS

Co-locating dental care with mental health care may increase dental utilization among people with serious mental illness, possibly by mitigating known barriers to dental care for this population. Among African Americans, the co-location of dental care with mental health care may also attenuate the negative effect of prior racial discrimination in a medical setting on dental utilization.

Oral health self-care behaviours in serious mental illness: A systematic review and meta-analysis

AIM

To understand the relationship between serious mental illness and oral health self-care behaviours using meta-analytic methods and a narrative synthesis of available literature.

METHOD

The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines [PROSPERO reference: CRD42020176779]. Search terms pertaining to serious mental illness and oral health were entered into EMBASE, PsycINFO, Medline and CINAHL. Eligible studies included a sample of people with a serious mental illness and a quantitative measure of an oral health self-care behaviour (eg dental visits, toothbrushing). The Effective Public Health Practice Project tool was utilised to appraise the quality of the literature. Studies in the meta-analysis contained a non-clinical or general population comparator sample.

RESULTS

People with a serious mental illness were significantly less likely to visit the dentist (OR 0.46, 95% CI 0.32-0.065, p > 0.001) or brush their teeth (OR 0.19, 95% CI 0.08-0.42, p < 0.001) when compared to non-clinical comparator samples. Few studies explored other oral health self-care behaviours (eg flossing and mouth washing), but uptake was generally low in people with a serious mental illness. The study quality of included studies was variable.

CONCLUSIONS

The research showed a reduced uptake of oral health self-care behaviours in people with a serious mental illness. Suboptimal oral health can negatively impact on physical, social and psychological functioning. Further research is needed to understand the reasons for low rates of oral health self-care behaviours in this population.

Schizophrenia and Dental Health: A Systematic Review

ABSTRACT

Schizophrenia is characterized not only by psychopathological symptoms but also by medical comorbidities. Among the latter, there are limited data on dental health. We conducted a systematic review with the primary aim of clarifying the extent of the relationship between dental diseases and schizophrenia. The second aim was to delineate an intervention program based on illness-related factors that influence dental health. The preferred reporting items for systematic reviews and meta-analyses statement for reporting systematic reviews was used. Only articles published in English language peer-reviewed journals were considered; we excluded case reports, meta-analyses, and systematic reviews, as well as studies that did not clearly report statistical analysis, diagnostic criteria, or the number of patients included. Twenty-one studies comprising 13,110 patients with schizophrenia and 9025 healthy controls were included. Negative symptomatology, long duration of illness, smoking habit, drug-induced xerostomia, and neuroinflammation are the most critical areas. We suggest an intervention program for prevention and treatment of dental diseases in schizophrenia.

Oral Health Interventions in Patients with a Mental Health Disorder: A Scoping Review with Critical Appraisal of the Literature

Poor oral health affects quality of life and daily functioning in the general population and especially in patients with mental health disorders. Due to the high burden of oral health-related quality of life in patients with a mental health disorder, it is important for nurses to know how they can intervene in an early phase. The aim of this systematic scoping review was to identify and appraise oral health interventions in patients with a mental health disorder. A systematic scoping review with a critical appraisal of the literature was conducted using the Joanna Briggs Institute (JBI) methodology for scoping reviews and their checklists. MEDLINE, CINAHL, PsycINFO and reference lists were searched from their inception until December 2020. Results: Eleven quantitative studies were included in the review: four randomized controlled trials, six quasi-experimental studies and one cohort study. Studies focused on interventions for patients (n = 8) or focused on patients together with their professionals (n = 3). Four types of oral health interventions in mental health were found: (I) educational interventions; (II) physical interventions; (III) interventions combining behavioural and educational elements and (IV) interventions combining educational and physical elements. All studies (n = 11) had an evaluation period ≤12 months. Nine studies showed an effect on the short term (≤12 months) with regard to oral health knowledge, oral health behaviour, or physical oral health outcomes (e.g., plaque index). Two studies showed no effects on any outcome. Overall, the methodological insufficient to good. Conclusion: Four types of interventions with positive effects (≤12 months) on oral health knowledge, oral health behaviour, and physical oral health outcomes in different diagnostic patient groups were found. Due to the heterogeneity in both interventions, diagnostic groups and outcomes, one golden standard oral health intervention cannot be advised yet, although the methodological quality of studies seems sufficient. Developing an integrated oral health toolkit might be of great importance in mental health considering its potential effect on oral health-related quality of life.

A qualitative study on experiences of persons with schizophrenia in oral-health-related quality of life

Our study aimed to explore the views and experiences in oral health and oral-health-related quality of life (OHRQoL) of persons with schizophrenia (PWS) in order to expand the understanding of the factors that either limit or facilitate their healthcare pathway, which can ultimately optimize their oral health and/or OHRQoL. A qualitative study was conducted in France in the Côte d'Or department (530 000 in habitants) centered on PWS's perceived meanings regarding oral health or OHRQoL, and semi-structured individual interviews were used. A conventional content analysis approach was chosen in order to highlight unrevealed themes. A sample of 20 PWS (12 males; 8 females) with a median age was 45.8 (± 9.5) were recruited to assess views and experiences regarding OHRQoL, which were focused on three dimensions: an individual dimension related to experience of "oral symptoms", a second dimension related to experience of "stress and its management", and a third related to "Autonomy dimension in oral health". We showed that PWS clearly expressed their mental representations of oral health and OHRQoL. This study supports that PWS were able to define their needs and had the ability to discuss their oral health and OHRQoL. These finding could be used to support specific interventions for this population to better manage the negative impact of antipsychotics and help them to consult dentists on a regular basis.

Potential Cross-Links of Inflammation With Schizophreniform and Affective Symptoms: A Review and Outlook on Autoimmune Encephalitis and COVID-19

Based on current implications of the SARS-CoV-2 pandemic with regards to mental health, we show that biological links exist between inflammation and mental illness in addition to psychoreactive effects. We describe key principles of the biological interaction of the immune system and the mind, as well as the possible routes of viral entry into the brain. In addition, we provide a stepwise scheme for the diagnosis and therapy of autoimmune-encephalitis with schizophrenia-like symptomatology as a general guide for clinical practice and in the specialized scenario of infections, such as those caused by the SARS-CoV-2 virus.

Prevalence and Clinical Correlation of Decayed, Missing, and Filled Teeth in Elderly Inpatients With Schizophrenia

Introduction: Schizophrenia is a mental disease with a profound impact on human health. Patients with schizophrenia have poor oral hygiene, increasing their risk of systemic diseases, such as respiratory infections, and declining their quality of life. Therefore, this study aims to assess the oral health status of inpatients with schizophrenia, analyze its related factors, and thus provide scientific evidence for further exploration of corresponding control strategies. Methods: A total of 425 inpatients older than 50 years with a diagnosis of schizophrenia from two psychiatric hospitals (mean age 58.49 ± 5.72 years) were enrolled. The demographic data of the patients were checked on admission. Two independent dentists examined caries, missing teeth, and fillings. Mini-Mental State Examination (MMSE) and Global Deterioration Scale were performed as cognitive tests. Positive and Negative Syndrome Scale and Repeatable Battery for the Assessment of Neuropsychological Status rating scale were used to determine their mental status. Results: The average decayed, missing, and filled teeth index was 12.99 ± 8.86. Linear regression analysis showed that the decayed, missing, and filled teeth index had a significantly positive relationship with age (p < 0.001) and smoking (p < 0.001) and a negative relationship with MMSE (p = 0.029). The missing teeth index had a positive relationship with age (p < 0.001), smoking (p < 0.001), and Global Deterioration Scale (p = 0.014) and a negative relationship with MMSE (p = 0.004). Conclusion: The oral health of elderly patients with schizophrenia is poor, which may be related to the cognitive level of patients and affect their quality of life. The focus should be provided to the oral care of patients with schizophrenia, and investment in their specialized oral treatment should be increased.

Oral health perception and plight of patients of schizophrenia

OBJECTIVE

To assess the oral health status, perception and dental treatment needs in patients of schizophrenia in the hospital set-up in Rohtak district, Haryana.

METHODS AND RESULT

A cross-sectional study was conducted to assess the oral health in patients of schizophrenia at Postgraduate Institute of Medical Sciences, Rohtak, Haryana amongst patients with ≤48 score on BPRS. A modified Dental Coping Belief Scale along with a structured questionnaire and clinical examination were recorded. Descriptive and inferential statistics were used in relation to demographic variables. Amongst 111 subjects, 74.4% were males and the mean age was 34.73 ± 9.9 years. Around 77.5% had habit of regular mouth rinsing, 72% and 3% brushed their teeth once and twice daily, respectively. Subjects had high negative oral health beliefs and external locus of control for oral health. Compared to the general population, mean OHI (8.4 ± 2.5) and DMFT (3.09 ± 2.9) scores were higher. Nearly, 66% patients had gingival pockets and around 7% showed attachment loss above 3 mm or gingival recession.

CONCLUSION

Patients with schizophrenia have much poorer oral health as compared to general population. They are aware of their poor oral hygiene but are not motivated enough to take care of their oral health. A multifaceted approach is required to plan and undertake effective oral health preventive and rehabilitative measures for this special group.

Oral health among student veterans: Effects on mental and physical health

Objective: The purpose of this study was to explore differences in oral health among students by military service status in postsecondary settings. Participants: Secondary data were obtained from the American College Health Association's 2011-2014 National College Health Assessment II. Method: Demographic characteristics of the study sample were explored by calculating frequencies and percentages by military service status. Research questions were explored with maximum likelihood multiple logistic regression. Results: Service member and veteran students are at greater risk for neglecting health behaviors associated with positive oral health, including that they were less likely to get dental exams and that those who deployed in the past were the least likely to be practicing good oral health. Conclusions: The results suggest that improving oral health will contribute to improving health and mental health outcomes in this population, and provide important information for health specialists working with service members and veterans on college campuses.

Multiple implant therapy with multiple inductions of general anesthesia in non-compliant patients with schizophrenia: A case report

The effectiveness of dental implants in patients with disability, who are non-compliant during treatment, is controversial because of their poor oral health. Thus, oral health-care and management in such patients is concerning. Moreover, limited information is available on prognosis after implant placement. Herein, we describe a patient with schizophrenia who underwent dental implantation under multiple inductions of general anesthesia (5 times) and required conservative treatment and tooth extraction for multiple dental caries and retained roots because of inadequate oral health-care. Postoperatively, fracture of the prosthodontics and progression of dental caries were observed, and with 3 additional inductions of general anesthesia, conservative treatment, implant surgery, and prosthesis implantation were conducted. Postoperative 12-month follow-up since the last prosthesis implantation showed successful results. For patients with schizophrenia, multiple implantation can reduce horizontal bone loss and achieve aesthetic results compared to treatment with removable prosthodontics and could serve as an alternative treatment modality.

Dental treatment under general anesthesia in adults with special needs at the University Hospital of Dental Prosthetics and Restorative Dentistry of Innsbruck, Austria: a retrospective study of 12 years

OBJECTIVES

Special needs patients are prone to insufficient oral care and subsequent caries or periodontitis. The aim of this retrospective study was the assessment of demand for restorative therapy and tooth extractions under general anesthesia in adults with intellectual and/or physical disablement (IPD) or psychiatric disorders (PDs) with inherent dentist phobia at the University Hospital of Innsbruck with regard to demographic factors.

MATERIALS AND METHODS

A total of 444 consecutive cases of scheduled dental general anesthesia (DGA) in adults from 2003 to 2014 were included. From patient files, demographic data, the presence of either IPD or a PD, attested by a mandatory certificate, and restorative therapy and tooth extractions performed under DGA were obtained. Data analysis was carried out by means of descriptive and comparative statistics.

RESULTS

Four hundred two cases (mean age 37.5 ± 13.87 years) assigned to 283 individuals with IPD and 42 cases (mean age 36.09 ± 13.03 years) assigned to 39 individuals with PDs arose in the observed period. Patients with PDs required significantly more restorations (in 7.98 ± 5.4 versus 5.34 ± 4.41 teeth; p = 0.002; Mann-Whitney U test) and extractions (of 4.86 ± 4.51 versus 2.6 ± 3.96 teeth; p < 0.001; Mann-Whitney U test) than patients with IPD.

CONCLUSIONS

Demand for dental treatment was high in the collective of special needs patients. Oral health status was worse in patients with PDs than in patients suffering IPD.

CLINICAL RELEVANCE

While in patients with severe disablement, DGA presents the only treatment option, specific preventive programs should be implemented for patients with minor disablement or dentist phobia. In these patients, alternative approaches should be promoted.

Poor oral health in patients with schizophrenia: A systematic review and meta-analysis

Increased rates of comorbid physical illness have been commonly reported in patients with schizophrenia. However, there are fewer data on dental disease in these patients. We systematically evaluated existing data on the oral health survey of schizophrenia patients through meta-analysis. Using the available databases, we performed a systematic search to identify the studies examining the oral health in schizophrenia patients from January 1997 to June 2017, based on the inclusion and exclusion criteria. Two investigators extracted the related data independently. The meta-analysis was performed by using the RevMan 5.3 software after data extraction and quality assessment. We compared the oral health results between the schizophrenia patients and the general population, including the following measures: the mean number of decayed, missing and filled teeth (DMFT). Eight studies comprising 2640 patients with schizophrenia and 19,698 healthy controls were included in the meta-analysis. The patients with schizophrenia had significantly higher scores of dental caries (mean difference [MD] = 7.77, 95% confidence interval [CI] = 3.27 to 12.27), missing teeth (MD = 7.61, 95% CI = 3.44 to 11.77), and decayed teeth (MD = 3.44, 95% CI = 2.06 to 4.82) compared to controls (all p < 0.01). By contrast, the schizophrenia patients had fewer score of filled teeth (MD = -3.06, 95% CI, -4.82 to -1.30) than the controls (p < 0.01), indicating decreased access to dental care. Our systematic review suggests that patients with schizophrenia have worse oral health than the general population, but have received less dental care services. Hence, the oral health services should be taken into account in the patients with schizophrenia.

Providing oral care for adults with mental health disorders: Dental professionals' perceptions and experiences in Perth, Western Australia

OBJECTIVE

To explore dental professionals' perceptions and experiences of providing oral health care for adults with mild to moderate mental health disorders (MHD) in Perth, Western Australia.

METHODS

A grounded theory approach guided this research which comprised semi-structured interviews with oral health professionals working in private and/or public dental facilities attended by adults with MHD. An iterative analysis of transcripts identified emerging issues that were organized into categories under which key themes were noted, coded, compared, discussed, reviewed and revised independently by two researchers to ensure rigour.

RESULTS

Sixteen interviews were conducted with six general dentists, three dental specialists, four oral health therapists (OHT) and three dental assistants. Barriers to providing oral health care for adults with MHD included limitations of the current model of care, often focused on treating advanced disease; limited inter-professional collaboration; an over-burdened public dental system and the financial constraints of private practice. Personal barriers included perceptions that people with MHD had limited capacity for self-care and preventing oral disease. Factors that would enable oral health care included training and professional development for dental professionals to work effectively with people with MHD and a more flexible, inter-professional approach that involved prevention and inviting family to consultations about oral health in primary health care settings.

CONCLUSIONS

Our study reveals structural barriers where services often appear to be inadequately prepared to meet the oral health needs of people with MHD. This suggests the need for strategies to review current models of care and encourage and support dental professionals to provide oral health care that is inclusive, inter-professional, focused on prevention and sensitive to the social context and lived experience of people with MHD.

Oral health experiences and needs among young adults after a first-episode psychosis : a phenomenological study

WHAT IS KNOWN ON THE SUBJECT?: Substance abuse, poor lifestyle and side effects of medication often occur and cause oral health problems in patients diagnosed with severe mental illness (SMI). Oral health in SMI is related to quality of life, self-esteem, and daily functioning. Despite its importance, oral health in mental health care is still a postponed healthcare pathway. Treatment guidelines on patients after a first episode psychosis (FEP) indicate that interventions are recommended, but clinical advice is lacking. However, no research on the experiences of young adults' oral health after FEP has been conducted. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This study is the first study to gain insight into most important experiences in patients after FEP regarding oral health. After FEP, participants experience many risk factors, for example substance use, poor diet and financial problems, and participants are not able to adequately attend to their oral health. There is a lack of awareness among participants after FEP about oral health and participants do have high burden. After FEP, participants need support and help from their environment to maintain their oral health. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: In FEP, oral health needs more attention to avoid the negative consequences in a later phase of the illness. To fill the gap between patients' needs regarding oral health care and the attention of mental healthcare professionals, the awareness of patients and mental health professionals concerning oral health should be heightened, and clinical interventions to support these needs should be developed.

ABSTRACT

Introduction Oral health affects quality of life, self-esteem, physical health and daily functioning. Treatment guidelines on patients after first episode psychosis (FEP) recommend interventions, but clinical interventions are lacking. No research on the experiences of young adults' oral health after FEP has been conducted. Aims This study aimed to explore the lived experiences and needs of patients after FEP with regard to their oral health. Design and Methods Single-centre phenomenological study using open interviews (N = 30). Data were analysed using the Colaizzi method. Results Patients reported oral health problems since their FEP. The problems that patients encountered were dental care in general (e.g., a lack of awareness), risk factors (e.g., substance use, poor diet and financial problems), overall experiences with dentists/dental hygienists and the gap between needs and interventions. Discussion There is a lack of awareness among patients after FEP about oral health while patients are not able to adequately attend to their oral health and patients have high burden on this topic. Implications for mental health nursing To bridge the gap between patients' needs regarding oral health, the awareness of patients and mental health professionals should be heightened, and patients should be better supported by mental health professionals.

Oral Health Needs and Experiences of Medicaid Enrollees With Serious Mental Illness

INTRODUCTION

Chronic dental diseases are among the most prevalent chronic conditions in the U.S., despite being largely preventable. Individuals with mental illness experience multiple risk factors for poor oral health and need targeted intervention. This study investigated experiences of Kansas Medicaid enrollees with serious mental illness in accessing dental services, examined their oral health risk factors, and identified oral health needs and outcomes.

METHODS

Survey data were collected from October 2016 through February 2017 from 186 individuals in Kansas with serious mental illness enrolled in Medicaid. Data were analyzed quantitatively (descriptive and bivariate statistics) and qualitatively (for major themes).

RESULTS

Despite Medicaid coverage of dental cleanings, 60.2% of respondents had not seen a dentist in the last 12 months. Reasons included out-of-pocket costs, lack of perceived need, uncertainty about coverage, difficulty accessing providers, fear of the dentist, and transportation issues. High rates of comorbid physical health conditions, including diabetes and cardiovascular disease, and current or former tobacco use were also observed.

CONCLUSIONS

Medicaid dental benefits that cover only dental cleanings and low levels of oral health knowledge create barriers to utilizing needed preventive dental care. Lack of perceived need for preventive dental services and lack of contact with dentists necessitates the development of targeted oral health promotion efforts that speak to the specific needs of this group and are disseminated in locations of frequent contact. The Medicaid population with serious mental illness would be an ideal group to target for the integration of chronic oral, physical, and mental health prevention services and control.

The oral health of long-term psychiatric inpatients in Singapore

This cross-sectional study aims to describe the dental caries experience, treatment needs, and experience of dry mouth of 191 long-term psychiatric inpatients in Singapore. Medical history, dental caries experience [represented by the Decayed Missing or Filled Teeth index (DMFT)], salivary flow, and treatment needs were recorded. Information on brushing, pain (when eating), and xerostomia was gathered. Bivariate analysis was used to examine the associations of DMFT, saliva flow, the presence of salivary gland hypofunction (SGH), and xerostomia. Simple linear regression was used to examine the association between SGH and DMFT. The sample comprised 143 men (74.9%) and 48 women (25.1%), aged 24 to 80 years old. 169 patients (88.5%) had schizophrenia. DMFT ranged from 0 to 32, with a mean of 21.6 (SD 9.7). Mean DMFT scores were significantly higher among males and older patients. 77 of 176 patients (43.8%) were found to have SGH. SGH was associated with a higher mean DMFT. Those taking classical antipsychotics and anticholinergics had significantly lower mean saliva flow and tended to have SGH. 107 of 165 patients (64.8%) were found to experience xerostomia. Long-term psychiatric inpatients in Singapore have poor oral health, unmet treatment needs, and suffer from dry mouth.

Eating Behaviors and Related Factors in Psychiatric Patients

The aim of this study was to determine the risk of eating disorders and associated risk factors in individuals with psychiatric disorders. Patients who were hospitalized in a psychiatry clinic of the university hospital between the dates of February 2014 and July 2014 constitute sample for the study. The study sample consisted of a total of 216 patients. Data were collected using a questionnaire form and the Eating Attitude Test. The mean age of the patients was 37±0.5, and 56.9% of the patients were female. Problems in eating behavior were observed in 11.6% of the patients, and a statistically significant relationship was found between the risk of eating disorders and diagnosis, gender, exercise and self-perception of weight. The risk of eating disorders was more frequently observed in patients diagnosed with depression, in female patients with a self-perceived weight problem and do not exercise.

Enhancing oral health for better mental health: Exploring the views of mental health professionals

The association between oral health, self-esteem and quality of life is well established yet there is limited research on the impact of addressing the poor oral health of people living with mental health disorders. Greater consideration is warranted on how enhancing oral health in the course of mental healthcare might reduce the burden of a person's ill health. The role of mental health professionals is important in this regard yet uncertainty persists about the role these providers can and should play in promoting oral health care for people with mental health disorders. This qualitative study explored the issue of oral health and mental health with community based mental health professionals in Perth, Western Australia. It examined their views on the oral health status and experiences of their clients, and the different and alternative ways to improve access to care, knowledge and preventative regimens. Findings indicated participants' ambivalence, reluctance and lack of training in raising oral health issues, despite its acknowledged importance, indicating a siloed approach to care. Findings offer an opportunity to reflect on whether a more integrated approach to oral health care for people with mental health disorders would improve health outcomes.

Dental implants placement in paranoid squizofrenic patient with obsessive-compulsive disorder: A case report

Background

Paranoid schizophrenia is a mental illness that involves no observable anatomical alteration. Main characteristic affects the personality of the individual, as well as areas of his own psychology.

Case Report

A 33-year-old man with paranoid schizophrenia and obsessive-compulsive disorder in treatment with Haloperidol, Oxcarbazepine, Olanzapine and Seroquel is presented. Dental exploration showed widespread decay mostly cervical with numerous root fragments, agenesis of lateral incisors, impacted wisdom teeth, missing teeth and malocclusion. Treatment plan included restoration of teeth decay, extractions of root fragments and implant-supported prostheses in bilateral upper lateral incisors for aesthetics reason. A previous consultation with a psychiatric specialist was performed and no contraindication were observed. A preliminary radiological examination was performed previous dental treatment and implant placement. Due to patient refusal to replace dental abscenses with implants, inform consent was signed up from his parents. After local anesthesia, first implant was placed at upper right lateral positions (Straumann Bone Level Ø 3.3 mm, length 10 mm). Two weeks later a second implant was placed at upper left lateral position (Straumann Bone Level Ø 3.3 mm, length 12 mm). The patient showed no postoperative complications. After implant placement, the patient attended scheduled review appointments. The prosthesis was placed after a 3-month period of osseointegration.

Conclusions

Implant placement can be considered a suitable option for people with mental disorders. A previous consultation with psychiatric specialists for conducting a good patient management is necessaire.

Key words:Paranoid schizophrenia, obsessive-compulsive disorder, dental implants.

Parity of esteem: Addressing the inequalities between mental and physical healthcare

Parity of esteem means valuing mental health as much as physical health in order to close inequalities in mortality, morbidity or delivery of care. There is clear evidence that patients with mental illness receive inferior medical, surgical and preventive care. This further exacerbated by low help-seeking, high stigma, medication side-effects and relatively low resources in mental healthcare. As a result, patients with severe mental illness die 10–20 years prematurely and have a high rate of cardiometabolic complications and other physical illnesses. Many physical healthcare guidelines and policy recommendations address parity of esteem, but their implementation to date has been poor. All clinicians should be aware that inequalities in care are adversely influencing mental health outcomes, and managers, healthcare organisations and politicians should provide resources and education to address this gap.

Learning Objectives

• Understand the concept of parity of esteem

• Be aware of the current inequalities in mental healthcare

• Appreciate how parity of esteem may be improved

The Porphyromonas gingivalis/Host Interactome Shows Enrichment in GWASdb Genes Related to Alzheimer's Disease, Diabetes and Cardiovascular Diseases

Periodontal disease is of established etiology in which polymicrobial synergistic ecology has become dysbiotic under the influence of Porphyromonas gingivalis. Following breakdown of the host's protective oral tissue barriers, P. gingivalis migrates to developing inflammatory pathologies that associate with Alzheimer's disease (AD). Periodontal disease is a risk factor for cardiovascular disorders (CVD), type II diabetes mellitus (T2DM), AD and other chronic diseases, whilst T2DM exacerbates periodontitis. This study analyzed the relationship between the P. gingivalis/host interactome and the genes identified in genome-wide association studies (GWAS) for the aforementioned conditions using data from GWASdb (P < 1E-03) and, in some cases, from the NCBI/EBI GWAS database (P < 1E-05). Gene expression data from periodontitis or P. gingivalis microarray was compared to microarray datasets from the AD hippocampus and/or from carotid artery plaques. The results demonstrated that the host genes of the P. gingivalis interactome were significantly enriched in genes deposited in GWASdb genes related to cognitive disorders, AD and dementia, and its co-morbid conditions T2DM, obesity, and CVD. The P. gingivalis/host interactome was also enriched in GWAS genes from the more stringent NCBI-EBI database for AD, atherosclerosis and T2DM. The misregulated genes in periodontitis tissue or P. gingivalis infected macrophages also matched those in the AD hippocampus or atherosclerotic plaques. Together, these data suggest important gene/environment interactions between P. gingivalis and susceptibility genes or gene expression changes in conditions where periodontal disease is a contributory factor.

A Rasch Analysis between Schizophrenic Patients and the General Population

Background

The aim of this study was to test the General Oral Health Assessment Index Questionnaire (GOHAI) items for differential item functioning (DIF) according to demographic characteristics (gender, age) and mental health status (schizophrenic disorders versus general population) using Rasch analysis.

Methods

This is a cross-sectional study using aggregated baseline data from a validation study of the GOHAI in the French general population (GP) and similar validation study in persons with schizophrenia (PWS). DIF was tested using the Partial Credit Model. DIF were estimated in different groups of patients.

Results

The cohort comprised 363 persons: 65% were female, 83% were 25-45 years old and 30% were PWS.Five of the 12 items exhibited DIF. DIF effects were observed with schizophrenia for 3 items, with age for 3 items and with gender for 1 item. The variable “age” gave a significant explanation of the latent variable: the latent variable decreased with age (-0.40±0.08-p<0.001 for each increase of the age of 10 years). This decrease represented an effect size of 0.27 which can be qualified of a small to medium effect. The status of the individuals (GP versus PWS) and the gender did not significantly explain differences in the values of the latent variable.

Conclusion

The GOHAI scores may not be comparable across sub-groups defined by health status, age and gender without accounting for DIF. In the future, other studies should explore this way with other Oral Health related Quality of Life assessment tools and populations with mental illness.

Patients with Psychiatric Disorders: What the General Dental Practitioner Needs to Know

Psychiatric illness is extremely common and the general dental practitioner (GDP) will inevitably encounter patients with such an illness. This article outlines common psychiatric conditions that the GDP should be familiar with alongside its impact on oral health. It also gives a systematic approach to dealing with a patient who presents to practice with an undiagnosed psychiatric illness, whereby the illness interferes with delivery of suitable dental care.

Necessity of oral health intervention in schizophrenic patients - A review

Individuals with mental illness often cannot perform day to day activities due to a psychiatric or emotional disorder. Schizophrenia is one such psychiatric disorder characterized by worsening self-care ability with progressing mental illness. This disease may potentially deteriorate oral health by affecting the subject's ability to perform oral hygiene measures. Literature on oral disease manifestations in schizophrenia is limited. Lack of desire for oral health care as well as generally poor awareness of oral health issues in these patients, compounded further by side effects of medications, may complicate dental management in schizophrenic patients. The present review explores clinical features and possible factors associated with oral health status among those with Schizophrenia.

Oral Hygiene - A Challenge in Everyday Life for People with Schizophrenia

The aim of the study is to explore how adults with schizophrenia describe their lived experiences with oral hygiene. 23 adults with schizophrenia were interviewed within a period of four months in late 2015. Transcriptions of the interviews were analysed using the Reflective Lifeworld Research phenomenological approach of Dahlberg, Dahlberg, and Nyström. The essence of the phenomenon, oral hygiene, is described as a challenge: a mixture of ability and assigning priority; a challenge in which significant others, for better or worse, play an important role. We recommend a systematic cooperation between health care professionals and adults with schizophrenia in order to improve oral health, well-being and recovery.

Effects of an educational intervention on oral hygiene and self-care among people with mental illness in Japan: a longitudinal study

Background

The oral hygiene of patients with a mental illness is an important concern in psychiatric care, and it is necessary to increase the level of self-care among these patients. In this study, we administered an oral care questionnaire to people with mental illness in Japan and compared their answers before (baseline) and at 1 week and 1, 3 and 6 months after they participated in an educational program.

Methods

The questionnaire was distributed to 390 patients. It included questions about age, education, income, between-meal snacks, number of teeth, frequency of tooth brushing, and other items. The educational program was developed for the purposes of improving self-care.

Results

Before the program, the proportion of male patients who had had a mental illness for ≥ 10 years was significantly higher among those patients who did not brush their teeth before bed. In addition, such patients did not have primary care dentists, and a significantly higher proportion of male patients, compared with female patients, did not undergo routine dental checkups more than once per year. The educational program resulted in an improvement in the use of fluoride toothpaste from baseline to 6 months after the intervention (p = 0.001). The daily use of interdental brushes or floss was significantly different 6 months after the intervention.

Conclusions

Male and long-term inpatients need oral hygiene instructions. Our educational program showed the effects of using oral hygiene tools. Future studies should include a control group to measure the impact of the educational program.

Psychometric characteristics of the "General Oral Health Assessment Index (GOHAI) » in a French representative sample of patients with schizophrenia

BACKGROUND

The "General Oral Health Assessment Index" (GOHAI) was widely used in clinical or epidemiological studies worldwide, as it was available for use in different languages. Therefore, the aim of this study was to evaluate the psychometric characteristics of the GOHAI in a representative sample of patients with schizophrenia.

METHODS

A total of 90 schizophrenic patients (in-patients and out-patients) were recruited from the participants of the "buccodor study" (NCT02167724) between March and September 2015. They were selected using a random stratified sampling method according to their age, sex, or residential area (urban/rural area). GOHAI validity (construct, predictive, concurrent and known group validity) and internal consistency (reliability) were tested. Test-retest reliability was evaluated in 32 subjects.

RESULTS

The mean age was 47.34 (SD = 12.17). Internal consistency indicated excellent agreement, with a Cronbach's α value of 0.82 and average inter-item correlation of 0.65. Intraclass correlation coefficients for test-retest reliability with 95% confidence intervals were not significantly different (p > 0.05). Construct validity was supported by three factor that accounted for 60.94% of the variance observed. Predictive validity was corroborated as statistically significant differences were observed between a high GOHAI score, which was associated with self-perceived satisfaction with oral health, lower age and high frequency of toothbrushing. Concurrent validity was corroborated as statistically significant relationships were observed between the GOHAI scores and most objective measures of dental status. For known group validity, they was no significant difference of the mean GOHAI score between out or in-patients (p > 0.05).

CONCLUSION

Acceptable psychometric characteristics of the GOHAI could help caregivers to develop ways to improve the Oral Health related Quality Of Life of schizophrenic patients.

Severity of illness and extra pyramidal symptoms as predictors for oral diseases among patients with schizophrenia

OBJECTIVE

The study explores the association between severity of illness (positive, negative, depressive and cognitive symptoms) and extra pyramidal symptoms (EPS) with dental caries, periodontal disease and prosthetic needs among patients with schizophrenia.

MATERIAL AND METHODS

A total of 71 schizophrenic patients diagnosed based on ICD-10 criteria participated in the study. Clinical Global Impression - Schizophrenia (CGI-SCH) scale was used to evaluate positive, negative, depressive, cognitive symptoms and overall severity of schizophrenia. Simpson-Angus Scale (SAS) was used for assessment of EPS. Dental examinations were conducted as per WHO (1997) criterion.

RESULTS

Mean DMFT and CPI scores with periodontal pockets were 5.57 ± 2.12 and 2.37 ± 0.74; significant differences being noted among those with and without EPS (p < 0.001). Positive and EPS associated with dental caries with odds ratio of 5.26 (1.05, 26.2) and 8.52 (2.31, 31.4) (p < 0.001). Depressive and EPS were associated with periodontal disease with odds ratio of 4.19 (1.53, 32.5) and 5.27 (1.29, 21.5), respectively (p < 0.001). Cognitive and EPS were associated with dental prosthetic needs with odds ratio of 4.33 (1.47, 31.2) (p < 0.001) and 7.78 (1.43, 42.2), respectively (p < 0.001).

CONCLUSIONS

Patients with schizophrenia had high dental caries, periodontal disease and unmet dental prosthetic needs. Severity of the schizophrenic and EPS was associated with poor oral health. Efforts need to be focused on strengthening the evidence of its association with oral health indicators through further studies including cohort investigations.

Barriers and enablers for oral health care for people affected by mental health disorders

BACKGROUND

People with mental health disorders are reported to have poorer access to dental services and poorer oral health outcomes. The aim of this paper is to analyze current published work regarding barriers and enablers for oral health outcomes and access to dental care for adults with mental health disorders which will be addressed from individual, organizational and systemic perspectives METHODS: A narrative review based on a search of the relevant published work regarding oral health for people with mental health disorders was undertaken using Medline, Web of Science, ERIC and Psychlit. Any relevant systematic reviews were highlighted in this process along with primary studies.

RESULTS

The published work repeatedly verified poorer oral health and inadequate access to dental services in people with mental health disorders. The published work identified barriers at individual, organizational and systemic levels. Much of the published work focused on barriers with less focus on enablers and interventions.

CONCLUSIONS

Considerable investigation of barriers had not elucidated options to improve care or outcomes.

Dental caries status of patients with schizophrenia in Seville, Spain: a case-control study

BACKGROUND

The aim of this study was to assess the dental status (DMFT) in patients with schizophrenia compared with a control group.

MATERIAL

In this case-control study, 50 patients with schizophrenia attended in the Psychiatric Unit at the Virgen Macarena University Hospital of Seville were compared with 50 people (without systemic diseases and not taking psychotropic drugs) in a control group attended in the School of Dentistry of Seville. Decayed, missing and filled teeth (DMFT) were assessed according to the World Health Organization WHO criteria.

RESULTS

Patients with schizophrenia showed a decayed teeth (DT) score of 7.26 ± 5.69 compared with 6.50 ± 4.37 for patients the control group. These differences were significant and suggest that dental caries are most prevalent in patients with schizophrenia. People who smoked showed significantly higher DT scores in both groups. Among patients with schizophrenia, smokers scored 9.34 ± 5.42 compared with 4.38 ± 4.82 for non-smokers. Among the healthy controls, smokers scored 6.88 ± 4.85 compared with 6.12 ± 3.85 for non-smokers (p < 0.05). Patients with schizophrenia showed a missing teeth (MT) score of 9.10 ± 8.56 compared with 5.38 ± 5.14 in control patients. MT scores increased significantly with age and with smoking in both groups of patients (p < 0.05). Patients with schizophrenia showed a filled teeth (FT) score of 1.38 ± 2.70 compared with 2.34 ± 3.48 in control patients. FT differences in gender and smoking habits between patients with schizophrenia and healthy control subjects were statistically significant (p < 0.05). This data, along with the DT scores, suggests that patients with schizophrenia have extensive untreated dental disease.

CONCLUSIONS

Patients with schizophrenia constitute a high risk population for dental health. This group showed a greater prevalence of decayed and missing teeth and more extensive treatment needs.

Study protocol: a cluster randomized controlled trial to assess the effectiveness of a therapeutic educational program in oral health for persons with schizophrenia

BACKGROUND

Schizophrenia is a severe mental disorder that affects 1 % of the world's population, including 600,000 people in France. Persons with schizophrenia (PWS) have excess mortality (their life expectancy is reduced by 20 %) and excess morbidity. In addition, such persons may have a large number of missing or decayed teeth. Dental caries and periodontal measurement indexes are often twice as high as the level found in the general population. Poor oral health can also affect quality of life and oral health is inseparable from general health. The management of oral health problems needs a multidisciplinary approach. According to the World Health Organization, the aim of therapeutic education (TE) is to help patients take care of themselves and to improve empowerment and recovery. In this educational approach, it is important to take into account the patient's personal experience. Though rarely investigated, the personal experience of PWS in oral health quality of life (OHRQoL) must be used to build a therapeutic educational programme in oral health (TEPOH) in a multidisciplinary approach, and the effectiveness of this program must be evaluated.

METHODS/DESIGN

We report the protocol of a randomized controlled cluster study. This study will be conducted in twelve hospitals in France. We hypothesized that a decrease of 20 % in the proportion of patients with CPI ≥ 3 would establish the effectiveness of TEPOH. Therefore, 12 hospitals will be randomly allocated to either TEPOH or no TEPOH. Altogether, they will have to recruit 230 PWS, who will be randomly allocated with a ratio of 1:1 to one of two conditions: control without intervention versus the group benefitting from TEPOH.

DISCUSSION

If successful, the study will generate methodologically sound results that provide knowledge on the effectiveness of a TEP in oral health for PWS. The results can be used to promote OHRQoL in a global health approach and develop appropriate strategies to encourage and facilitate financial support for healthcare, the multidisciplinary treatment of dental disorders, and the development of training in oral and mental health for caregivers.

Utilization of dental care among patients with severe mental illness: a study of a National Health Insurance database

Background

The oral health of patients with severe mental illness is poor, in general, and this may be attributed, in part, to inadequate dental care. This study investigated dental care utilization among patients with severe mental illness using a national representative sample.

Methods

This study used Taiwan’s National Health Insurance Research Dataset for 2009. Patients with the diagnosis of severe mental illness (ICD-9-CM: 290–298) were recruited as the study sample, and others comprised the control. Any visit to a dentist was defined as positive in terms of dental care utilization. Regression analyses were applied to determine the odds of dental care utilization for each diagnostic entity of severe mental illness, compared with the general population and controlling for potential covariates.

Results

Only 40 % of 19,609 patients with severe mental illness visited the dentist within 12 months. This was significantly lower than the dental visit rate of 48.3 % for the control population (odds ratio [OR] = .72, 95 % confidence interval [CI] = .69–.74; P <0.0001). The odds of dental care utilization differed among the severe mental illness diagnostic categories; e.g., the odds were lowest among those with alcohol psychoses (OR = .54, CI = .43–.68), senile dementia (OR = .55, CI = .52–.59) and other organic psychoses (OR = .58, CI = .52–.65), and highest among those with mood disorder (OR = .89, CI = .85–.94), with schizophrenic patients occupying a mid-level position (OR = .63, CI = .59–.67).

Conclusions

Patients with severe mental illness received less dental care than the general population. Health care providers and caregivers of patients with severe mental illness should encourage them to visit the dentist regularly, in order to improve the oral health of these vulnerable patient groups.

The oral health of people with anxiety and depressive disorders - a systematic review and meta-analysis

BACKGROUND

Many psychological disorders are associated with comorbid physical illness. There are less data on dental disease in common psychological disorders such as depression and anxiety in spite of risk factors in this population of diet, lifestyle or antidepressant-induced dry mouth.

METHODS

We undertook a systematic search for studies of the oral health of people with common psychological disorders including depression, anxiety and dental phobia. We searched MEDLINE, PsycInfo, EMBASE and article bibliographies. Results were compared with the general population. Outcomes included partial or total tooth-loss, periodontal disease, and dental decay measured through standardized measures such as the mean number of decayed, missing and filled teeth (DMFT) or surfaces (DMFS).

RESULTS

There were 19 papers on depression and/or anxiety, and seven on dental phobia/anxiety (total n=26). These covered 334,503 subjects. All the psychiatric diagnoses were associated with increased dental decay on both DMFT and DMFS scores, as well as greater tooth loss (OR=1.22; 95%CI=1.14-1.30). There was no association with periodontal disease, except for panic disorder.

LIMITATIONS

Cross-sectional design of included studies, heterogeneity in some results, insufficient studies to test for publication bias.

CONCLUSION

The increased focus on the physical health of psychiatric patients should encompass oral health including closer collaboration between dental and medical practitioners. Possible interventions include oral health assessment using standard checklists that can be completed by non-dental personnel, help with oral hygiene, management of iatrogenic dry mouth, and early dental referral. Mental health clinicians should also be aware of the oral consequences of inappropriate diet and psychotropic medication.

The oral health of people with chronic schizophrenia: A neglected public health burden

OBJECTIVE

People with chronic schizophrenia have high rates of physical ill-health such as heart disease. However, there has been less attention to the issue of poor oral health including dental caries (tooth decay) and periodontal (gum) disease, although both have consequences for quality of life and systemic physical health. We therefore measured tooth decay and gum disease in Malaysians with schizophrenia.

METHODS

We recruited long-stay inpatients with schizophrenia from June to October 2014. Four dental specialists assessed oral health using the decayed-missing-filled teeth index, the Community Periodontal Index of Treatment Needs and the Debris Index of the Simplified Oral Hygiene Index. Results were compared with the 2010 Oral Health survey of the general Malaysian population.

RESULTS

A total of 543 patients participated (66.7% males, 33.3% females; mean age = 54.8 years [standard deviation = 16.0]) with a mean illness duration of 18.4 years (standard deviation = 17.1). The mean decayed-missing-filled teeth was 20.5 (standard deviation = 9.9), almost double that of the general population (11.7). Higher decayed-missing-filled teeth scores were associated with both older age (p < 0.001) and longer illness duration (p = 0.048). Only 1% (n = 6) had healthy gums. Levels of decay and periodontal disease were greatest in those aged between 45 and 64 years, coinciding with the onset of tooth loss.

CONCLUSION

Dental disease in people with schizophrenia deserves the same attention as other comorbid physical illness. The disparity in oral health is most marked for dental decay. Possible interventions include oral health assessments using standard checklists designed for non-dental personnel, help with oral hygiene, management of iatrogenic dry mouth and early dental referral.

Oral Hygiene in Patients With Severe Mental Illness: A Pilot Study on the Collaboration Between Oral Hygienists and Mental Health Nurses

PURPOSE

To test (a) the effects of an educational intervention about oral hygiene on the knowledge of mental health nurses, and (b) the effects of an oral care intervention on oral health in patients with severe mental illness (SMI).

DESIGN AND METHODS

We applied a pretest/posttest design to test improvements in nurses' knowledge and the oral health of SMI patients.

FINDINGS

The nursing staff's knowledge increased significantly after the educational intervention. The oral health of the patients improved significantly after the oral health intervention.

PRACTICE IMPLICATIONS

Oral health of SMI patients can improve significantly with basic oral health interventions carried out by collaborating oral hygienists and mental health nurses.
