Oral health education (advice and training) for people with serious mental illness

Importance of oral health in mental health disorders: An updated review

Background

Mental disorders are indeed an expanding threat, which requires raised awareness, education, prevention, and treatment initiatives nationally and globally. This review presents an updated review on the relationships between oral health and mental health disorders and the importance of oral health in mental health disorders.

Method

A literature search was done regarding mental disorders and oral health approaches in Google Scholar and PubMed from the year 1995 until 2023. All the English-language papers were evaluated based on the inclusion criteria. Publications included original research papers, review articles and book chapters.

Results

Common mental disorders include depression, anxiety, bipolar disorder, Schizophrenia, dementia, and alcohol and drug use disorders. The interplay of oral health and mental disorders involves dysregulated microbiome, translocated bacteria, and systemic inflammation, among others.

Conclusion

There is a complex relationship between mental disorders and oral diseases. Various oral health problems are associated with mental health problems. The interplay of oral health and mental disorders involves dysregulated microbiome, translocated bacteria, and systemic inflammation, among others. Mental health nurses including physicians and dental professionals should be involved in the oral health care of mental health disorder patients. Therefore, multidisciplinary should be involved in the care of mental health disorders, and they should consider oral health care as an essential part of their care for patients with mental health disorders. Future investigations should strive to elucidate the exact biological relationships, to develop new directions for treatment.

Exploring the contextual factors, behaviour change techniques, barriers and facilitators of interventions to improve oral health in people with severe mental illness: A qualitative study

People with severe mental illness (SMI) have significantly poorer oral health compared to people without SMI and interventions targetted to improve oral health in this population failed to show any long-term improvement. Interventions are influenced by many contextual factors ranging from individual to systems level. This study aimed to understand the contextual factors, behaviour change techniques of the available oral health interventions and explore the barriers to and facilitators for engagement with these interventions from the perspectives of people with SMI (service users) and related service providers. Intervention details were extracted from 12 intervention studies identified from a previous systematic review using the template for intervention description and replication checklist (TIDieR) and behaviour change techniques (BCTs) were coded using the behaviour change technique taxonomy v1. Sixteen individual BCTs were identified and out of which "4.1 instructions on how to perform the behaviour" (n = 9) and "6.1 demonstration of behaviour" (n = 6) were most frequently used BCTs. Video vignettes prepared from the different intervention components identified from existing studies were shown to service users and service providers in dyadic or one-to-one interview format to elicit their views on barriers and facilitators for engagement with the intervention components. Interviews were analysed using Framework analysis and were guided by theoretical domains framework (TDF); and capability, opportunity and motivation (COM-B) model of behaviour change. Main facilitators identified to increase capability, opportunity and motivation of service users were the involvement of carers/care coordinators and integration of dental and mental health care, provision of oral health/hygiene information/products at an appropriate level and provision of tailored support according to individual needs and preferences. Barriers identified were related to lack of communication skills of the service providers, provision of coordinated care, lack of support in visiting a dentist and navigating the payment system and long follow up times. Appropriate training was considered as a facilitator, and staff turnovers and workload were considered as main barriers by the service providers. The findings suggest that comprehensive interventions that target barriers and enhance facilitators from individual to systems level are needed to improve oral health outcomes of people with SMI.

Improving oral health in people with severe mental illness (SMI): A systematic review

BACKGROUND

Those with severe mental illness (SMI) are at greater risk of having poor oral health, which can have an impact on daily activities such as eating, socialising and working. There is currently a lack of evidence to suggest which oral health interventions are effective for improving oral health outcomes for people with SMI.

AIMS

This systematic review aims to examine the effectiveness of oral health interventions in improving oral health outcomes for those with SMI.

METHODS

The review protocol was registered with PROSPERO (ID CRD42020187663). Medline, EMBASE, PsycINFO, AMED, HMIC, CINAHL, Scopus and the Cochrane Library were searched for studies, along with conference proceedings and grey literature sources. Titles and abstracts were dual screened by two reviewers. Two reviewers also independently performed full text screening, data extraction and risk of bias assessments. Due to heterogeneity between studies, a narrative synthesis was undertaken.

RESULTS

In total, 1462 abstracts from the database search and three abstracts from grey literature sources were identified. Following screening, 12 studies were included in the review. Five broad categories of intervention were identified: dental education, motivational interviewing, dental checklist, dietary change and incentives. Despite statistically significant changes in plaque indices and oral health behaviours as a result of interventions using dental education, motivational interviewing and incentives, it is unclear if these changes are clinically significant.

CONCLUSION

Although some positive results in this review demonstrate that dental education shows promise as an intervention for those with SMI, the quality of evidence was graded as very low to moderate quality. Further research is in this area is required to provide more conclusive evidence.

Hospital admissions for dental disorders in patients with severe mental illness in Southeast London: A register-based cohort study

In people with mental disorders, adverse general health is well recognized but dental diseases remain underinvestigated. The objective of this study was to investigate risk factors for hospital admissions for dental disorders in patients with severe mental illness (SMI) and/or depressive disorder. De-identified electronic mental health records from the South London and Maudsley NHS Foundation Trust (SLaM) were linked to national Hospital Episode Statistics (HES) data for analysis. Data were extracted for adults with a diagnosis of SMI (schizophrenia, schizoaffective disorder, bipolar disorder) and/or depression, who had received care at SLaM between 1 January 2010 and 31 March 2017. In the cohort of 18,999 patients thus obtained, the following factors were independently associated with hospital admission for dental disorders: female gender [odds ratio (OR) = 1.48, 95% CI: 1.31-1.68)], Health of the Nation Outcome Scales (HoNOS) problem drinking/drug taking (OR = 1.12, 95% CI: 1.05-1.19), HoNOS physical illness/disability (OR = 1.18, 95% CI: 1.12-.25), diabetes (OR = 1.24, 95% CI: 1.06-1.43), recorded current/past smoking (OR = 1.35, 95% CI: 1.06-1.43), treatment with antidepressant medication (OR = 1.48, 95% CI: 1.31-1.68), and depressive disorder (OR = 1.36, 95% CI: 1.11-1.68). Building on previous research in this population, which indicated a relatively high risk of acute care hospitalizations with dental disorders as discharge diagnoses, a number of demographic and clinical characteristics were found to be independent predictors over a 7-yr period. Further research into these predictors would facilitate a better understanding of how adverse dental outcomes might be prevented.

The Physical Health Care Fidelity Scale: Psychometric Properties

Mental health programs need an instrument to monitor adherence to evidence-based physical health care for people with serious mental illness. The paper describes the Physical Health Care Fidelity Scale and study interrater reliability, frequency distribution, sensitivity to change and feasibility. Four fidelity assessments were conducted over 18 months at 13 sites randomized to implementation support for evidence-based physical health care. We found good to excellent interrater reliability, adequate sensitivity for change, good feasibility and wide variability in fidelity across sites after 18 months of implementation. Programs were more successful in establishing Policies stating physical health care standards than in implementing these Policies. The Physical Health Care Fidelity Scale measures and guides implementation of evidence-based physical health care reliably.Trial registration: ClinicalTrials.gov Identifier: NCT03271242.

Effectiveness of oral health promotion program for persons with severe mental illness: a cluster randomized controlled study

OBJECTIVE

To evaluate the effectiveness of a composite oral health promotion program designed to reduce dental plaque among persons with severe mental illness in a psychiatric institution.

METHODS

A cluster randomized controlled study was carried out in chronic psychiatric wards of a general hospital in central Taiwan. Sixty-eight eligible male individuals admitted to 2 wards were randomly assigned to an experimental and a control group. Participants in the experimental group underwent an oral health promotion program that consisted of biweekly group education sessions, and a 12-week individual behavioral modification for oral hygiene course. The participants in the control group received usual care only. Dental plaque (measured by the Plaque Control Index) was examined by a single dentist before and after the experiment. Each participant responded to a questionnaire regarding oral health knowledge, attitude and behavior before and after the experiment.

RESULTS

Fifty-eight individuals completed the study. Before the experiment, the plaque index was similar between the intervention group (68.9; N = 27) and the control group (69.8; N = 31). After the experiment, the plaque index was significantly better in the intervention group than in the control group (42.6 vs. 61.8; P < 0.001). Participants in the intervention group also demonstrated better oral health knowledge, attitude and behavior than those in the control group after the experiment.

CONCLUSIONS

A composite oral health promotion program using both group education and individual behavioral methods over a 12-week period was effective in both reducing dental plaque and improving the oral health knowledge of persons with severe mental illness in the institution.

Assessment of risk factors for early childhood caries at different ages in Shandong, China and reflections on oral health education: a cross-sectional study

BACKGROUND

The high prevalence of early childhood caries (ECC) is widespread around the world, and oral health education (OHE) plays a vital role in preventing ECC. Numerous studies on ECC risk factor assessment have assisted us in enriching the content of OHE. The objective of this study was to further assess independent risk factors for ECC at different ages to provide evidence and insights for OHE.

METHODS

Children aged 3-5 years old (N = 1301) in Shandong Province were enrolled in this cross-sectional study. Data about oral health status and caregivers' oral health knowledge, attitude, and practice (KAP) were extracted from the 4th National Oral Health Survey of China. The associations between ECC prevalence and various KAP variables were tested with chi-square tests, bivariate analysis and multivariable logistic regression analyses.

RESULTS

The ECC prevalence in Shandong Province was 64.6%, and the dmft mean was 3.15. The independent variables with an increased risk for ECC were age, feeding method within 6 months of birth, bedtime sugar frequency, experience of toothache over the past year and dental visits (P < 0.05, chi-square tests). Complete breastfeeding within 6 months of birth primarily contributed to the high ECC risk of the 3-year-old group (OR: 3.39, 95% CI: 1.41-8.17), while high frequency bedtime sweet consumption mainly contributed to that of the 5-year-old group (OR: 3.22, 95% CI: 1.03-10.06; logistic regression analysis). Tooth brushing was not associated with ECC in this study, and some positive knowledge and attitude variables were positively correlated with a high risk of ECC.

CONCLUSION

These data provide evidence to suggest that the ECC-related risk factors at different ages are inconsistent, which provides some insights for OHE. We should highlight the effects of feeding methods in the early stages of deciduous dentition and sugar habits in the late stages of deciduous dentition on ECC, as well as encourage preventive dental visit and supplemental training for oral health practices.

One-to-one oral hygiene advice provided in a dental setting for oral health

BACKGROUND

Effective oral hygiene measures carried out on a regular basis are vital to maintain good oral health. One-to-one oral hygiene advice (OHA) within the dental setting is often provided as a means to motivate individuals and to help achieve improved levels of oral health. However, it is unclear if one-to-one OHA in a dental setting is effective in improving oral health and what method(s) might be most effective and efficient.

OBJECTIVES

To assess the effects of one-to-one OHA, provided by a member of the dental team within the dental setting, on patients' oral health, hygiene, behaviour, and attitudes compared to no advice or advice in a different format.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 10 November 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 10) in the Cochrane Library (searched 10 November 2017); MEDLINE Ovid (1946 to 10 November 2017); and Embase Ovid (1980 to 10 November 2017). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were also searched for ongoing trials (10 November 2017). No restrictions were placed on the language or date of publication when searching the electronic databases. Reference lists of relevant articles and previously published systematic reviews were handsearched. The authors of eligible trials were contacted, where feasible, to identify any unpublished work.

SELECTION CRITERIA

We included randomised controlled trials assessing the effects of one-to-one OHA delivered by a dental care professional in a dental care setting with a minimum of 8 weeks follow-up. We included healthy participants or participants who had a well-defined medical condition.

DATA COLLECTION AND ANALYSIS

At least two review authors carried out selection of studies, data extraction and risk of bias independently and in duplicate. Consensus was achieved by discussion, or involvement of a third review author if required.

MAIN RESULTS

Nineteen studies met the criteria for inclusion in the review with data available for a total of 4232 participants. The included studies reported a wide variety of interventions, study populations, clinical outcomes and outcome measures. There was substantial clinical heterogeneity amongst the studies and it was not deemed appropriate to pool data in a meta-analysis. We summarised data by categorising similar interventions into comparison groups.Comparison 1: Any form of one-to-one OHA versus no OHAFour studies compared any form of one-to-one OHA versus no OHA.Two studies reported the outcome of gingivitis. Although one small study had contradictory results at 3 months and 6 months, the other study showed very low-quality evidence of a benefit for OHA at all time points (very low-quality evidence).The same two studies reported the outcome of plaque. There was low-quality evidence that these interventions showed a benefit for OHA in plaque reduction at all time points.Two studies reported the outcome of dental caries at 6 months and 12 months respectively. There was very low-quality evidence of a benefit for OHA at 12 months.Comparison 2: Personalised one-to-one OHA versus routine one-to-one OHAFour studies compared personalised OHA versus routine OHA.There was little evidence available that any of these interventions demonstrated a difference on the outcomes of gingivitis, plaque or dental caries (very low quality).Comparison 3: Self-management versus professional OHAFive trials compared some form of self-management with some form of professional OHA.There was little evidence available that any of these interventions demonstrated a difference on the outcomes of gingivitis or plaque (very low quality). None of the studies measured dental caries.Comparison 4: Enhanced one-to-one OHA versus one-to-one OHASeven trials compared some form of enhanced OHA with some form of routine OHA.There was little evidence available that any of these interventions demonstrated a difference on the outcomes of gingivitis, plaque or dental caries (very low quality).

AUTHORS' CONCLUSIONS

There was insufficient high-quality evidence to recommend any specific one-to-one OHA method as being effective in improving oral health or being more effective than any other method. Further high-quality randomised controlled trials are required to determine the most effective, efficient method of one-to-one OHA for oral health maintenance and improvement. The design of such trials should be cognisant of the limitations of the available evidence presented in this Cochrane Review.

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.
