Role of health beliefs in patient compliance with preventive dental advice

Behavioral Interventions on Periodontitis Patients to Improve Oral Hygiene: A Systematic Review

This systematic review aimed to investigate the impact of different psychological models, strategies, and methods to improve plaque control and/or gingival inflammation in patients with periodontal diseases. Methods: The PubMed/MEDLINE, Cochrane Library, and Embase online databases were explored to identify relevant studies published before October 2022. Articles investigating the effects of different psychological approaches and intervention strategies on periodontitis patients’ oral hygiene (OH) behavioral change were screened. Results: 5460 articles were identified, and 21 fulfilled the inclusion criteria. In total, 2 studies tested audio-visual modalities, and the remaining 19 publications involved six psychological models of health-related behavioral interventions, including Social Cognitive Theory, the Theory of Planned Behavior, the Health Action Process Approach, Leventhal’s self-regulatory theory, Motivational Interviewing, and Cognitive Behavioral Therapy. A meta-analysis of the results was not carried out due to the high heterogeneity among the interventions. Conclusions: Considering the limitations of the available studies, psychological interventions based on social cognitive models that combine some of the techniques of this model (goal setting, planning, self-monitoring, and feedback) may improve OH in periodontitis patients, having a positive impact on periodontal clinical outcomes. Delivering cognitive behavioral therapy in combination with motivational interviewing may result in an improvement in OH as evaluated by decreasing plaque and bleeding scores.

Psychologically informed oral health interventions in pregnancy and type 2 diabetes: A scoping review

Introduction

Oral health is a critical aspect of gestational diabetes management. Gestational diabetes is high blood glucose levels during pregnancy and is managed like type 2 diabetes with diet and physical activity interventions. This scoping review sets out to discuss why oral health support should also become part of gestational diabetes management.

Objectives

The primary objective was to synthesise the existing psychologically informed oral health interventions for pregnant women and individuals with type 2 diabetes, and the extent to which these interventions map on to the COM-B Model. No literature exists on oral health interventions in gestational diabetes, why studies with type 2 diabetes populations were selected instead. The secondary objective was to identify the precise outcomes targeted in the interventions.

Methodology

The Joanna Briggs Institute's Methodology for Scoping Reviews was used to conduct this review. The populations of interest were pregnant women and individuals with type 2 diabetes, and eligible concepts were psychologically informed oral health interventions. Quasi-experimental and experimental designs were considered. The Ovid Interface including Embase, Medline, Global Health, APA PsychInfo, Health Management Information, Maternity, Infant Care Database, the Cochrane Library, and CINAHL was used as information sources. The study selection followed the PRISMA guidelines. The first search was conducted on the week commencing the 25th of July 2022, with a follow-up search conducted on the 10th of October 2022.

Results

28 records were included for synthesis. The most frequently assessed psychological outcome was oral health knowledge and the most frequently assessed oral clinical outcome was Plaque Index. All studies used an educational intervention approach, while psychological capability in the COM-B Model was targeted in all interventions by increasing oral health knowledge among the participants. The Health Belief Model was the most frequently used theory in the interventions.

Conclusion

The results demonstrate that oral health is a recognised aspect of pregnancy and type 2 diabetes. The findings from this review and a qualitative interview study which is under development will inform the first oral health intervention for women with gestational diabetes in the United Kingdom.

Oral Health Literacy in Migrant and Ethnic Minority Populations: A Systematic Review

Cultural background influences how migrants and ethnic minority populations view and assess health. Poor oral health literacy (OHL) may be a hindrance in achieving good oral health. This systematic review summarizes the current quantitative evidence regarding OHL of migrants and ethnic minority populations. The PubMed database was searched for original quantitative studies that explore OHL as a holistic multidimensional construct or at least one of its subdimensions in migrants and ethnic minority populations. 34 publications were selected. Only 2 studies specifically addressed OHL in migrant populations. Generally, participants without migration background had higher OHL than migrant and ethnic minority populations. The latter showed lower dental service utilization, negative oral health beliefs, negative oral health behavior, and low levels of oral health knowledge. Due to its potential influence on OHL, oral health promoting behavior, attitudes, capabilities, and beliefs as well as the cultural and ethnic background of persons should be considered in medical education and oral health prevention programs.

The effect of dental health education on pregnant women's adherence with toothbrushing and flossing - A randomized control trial

OBJECTIVES

In a three-arm randomized control trial, this study compared the efficacy of dental health education (DHE) with or without a planning intervention on adherence to oral health-related behaviours.

METHODS

Women (N=154) in their second trimester of pregnancy attending three maternal healthcare clinics in Kuwait completed an assessment of social cognitions and oral health behaviours before a debris and gingival assessment (Plaque Index [PI], Gingival Index [GI]) was undertaken; this was repeated at 1 month. In addition to treatment as usual (TAU), which was a demonstration of OH practices, intervention participants received one of two interventions: (i) DHE, which targeted social cognitions; or (ii) DHE and planning (DHE&P), which targeted social cognitions and intentions to undertake oral health behaviours. The TAU group was given a standard oral hygiene leaflet.

RESULTS

At Time one (T1) 154 women were eligible and randomly allocated to the three groups, respectively: treatment as usual (TAU)=53; DHE=53; DHE and planning=48. At Time two (T2), the number of women in each group completing the intervention (N=90) was, respectively, as follows TAU=28; DHE=30; DHE&P=32. There were no demographic differences between the groups at baseline. The mean age of women was 27.80±SD 5.40; 43% (n=38) had a high school level education. A mixed factor ANOVA analysis demonstrated that all women improved their PI (F=94.343 df=1 P=.001) and GI (F=73.138 df=1 P=.001) scores. There were no differences in self-reported oral hygiene and PI and GI by intervention group. The social cognition models (SCM) constructs changed over time in all women (N=90) except barriers to attendance (F=1.067 df=1 P=.305). There were no statistically significant differences in SCM constructs by intervention group at T2. All women reported increasing the frequency of toothbrushing and flossing.

CONCLUSIONS

The provision of information using a simple leaflet improved the adherence of Kuwaiti pregnant with toothbrushing and flossing advice, while the addition of DHE targeting social cognitions and planning conferred no additional benefits.

Using Intervention Mapping to Develop an Oral Health e-Curriculum for Secondary Prevention of Eating Disorders

Preventing oral-systemic health issues relies on evidence-based interventions across various system-level target groups. Although the use of theory- and evidence-based approaches has been encouraged in developing oral health behavior change programs, the translation of theoretical constructs and principles to behavior change interventions has not been well described. Based on a series of six systematic steps, Intervention Mapping provides a framework for effective decision making with regard to developing, implementing, and evaluating theory- and evidence-informed, system-based behavior change programs. This article describes the application of the Intervention Mapping framework to develop the EAT (evaluating, assessing, and treating) evidence-based intervention with the goal of increasing the capacity of oral health providers to engage in secondary prevention of oral-systemic issues associated with disordered eating behaviors. Examples of data and deliverables for each step are described. In addition, results from evaluation of the intervention via randomized control trial are described, with statistically significant differences observed in behavioral outcomes in the intervention group with effect sizes ranging from r=0.62 to 0.83. These results suggest that intervention mapping, via the six systematic steps, can be useful as a framework for continued development of preventive interventions.

Managing oral hygiene as a risk factor for periodontal disease: a systematic review of psychological approaches to behaviour change for improved plaque control in periodontal management

BACKGROUND

Plaque control in patients with periodontal disease is critically dependent upon self-care through specific oral hygiene-related behaviours.

OBJECTIVES

To determine the relationship between adherence to oral hygiene instructions in adult periodontal patients and psychological constructs. To determine the effect of interventions based on psychological constructs on oral health-related behaviour in adult periodontal patients.

DATA SOURCES

The Cochrane Oral Health Group's Trials Register, MEDLINE, EMBASE and PsycINFO.

STUDY APPRAISAL AND SYNTHESIS METHODS

Studies were grouped according to the study design, and appraised using an appropriate methodology, either the Newcastle-Ottawa assessment for observational studies, or the Cochrane criteria for trials.

RESULTS

Fifteen reports of studies were identified.

LIMITATIONS

There was a low risk of bias identified for the observational studies. Older trials suffered from high risk of bias, but more recent trials had low risk of bias. However, the specification of the psychological intervention was generally poor.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

The use of goal setting, self-monitoring and planning are effective interventions for improving oral hygiene-related behaviour in patients with periodontal disease. Understanding the benefits of behaviour change and the seriousness of periodontal disease are important predictors of the likelihood of behaviour change.

Association between dental prosthesis need, nutritional status and quality of life of elderly subjects

PURPOSE

To determine the effect of prosthesis need on nutritional status and oral health-related quality of life (OHrQoL) in elderly and to check the disparity between prosthesis need and prosthesis want in the Indian elderly.

METHODS

A total of 946 geriatric participants reporting to a geriatric medicine clinic were recruited in the study. Mini-nutritional assessment (MNA), geriatric oral health assessment (GOHAI) indices, prosthesis need according to WHO criteria, and prosthesis want was recorded along with age, gender, socioeconomic status and posterior occluding pair.

RESULTS

Significant associations exist between prosthesis need and age (p = 0.005), MNA (p = 0.006) and GOHAI (p = 0.000). Prosthesis demand too was influenced by age (p = 0.004), posterior occluding pairs (p = 0.000), MNA (p = 0.012) and GOHAI (p = 0.000). GOHAI was negatively correlated with upper (r = -0.445) and lower prosthesis need (r = -0.460). Participants with some prosthesis need had significantly lower MNA and GOHAI scores as compared to those with no prosthesis need. Though prosthesis need was high (79.7 %), demand was low (39.3 %).

CONCLUSION

Prosthesis need affects nutritional status and OHrQoL in elderly, and a wide gap exists between need and want of prosthesis.

The use of dental services for children: implications of the 2010 dental reform in Israel

Routine dental examinations for children are important for early diagnosis and treatment of dental problems. The level of dental morbidity among Israeli children is higher than the global average. A July 2010 reform of Israel's National Health Insurance Law gradually offers free dental services for children up to age 12. The study examines the use of dental services for children and the factors affecting mothers' decision to take their children for routine checkups. In addition, the study examines the impact of the reform on dental checkups for children in various populations groups. A national representative sample comprising 618 mothers of children aged 5-18 was surveyed by telephone. The survey integrated the principles of the health beliefs model and socio-demographic characteristics. The results show that mothers' decision to take their children for dental checkups is affected by their socio-demographic status and by their health beliefs with respect to dental health. After the reform, the frequency of children's dental checkups significantly increased among vulnerable populations. Therefore, the reform has helped reduce gaps in Israeli society regarding children's dental health. Raising families' awareness of the reform and of the importance of dental health care together with expanding national distribution of approved dental clinics can increase the frequency of dental checkups among children in Israel.

Health disparities and the multicultural imperative

Providing culturally and linguistically appropriate care is a crucial step toward the elimination of oral health disparities in the United States.

BACKGROUND

Health disparities, coupled with rapidly changing demographic trends, continue to plague healthcare, the health care workforce and population health. Consequently, there is still more work indicated to ensure individuals, regardless of race or ethnicity, receive quality health care at an affordable price. The purpose of this paper is to increase the awareness of oral health care practitioners about the causes and consequences of oral health disparities and to highlight promising strategies aimed at improving effective communication between health care providers and the patients they serve.

METHODS

A narrative utilizing key publications will explain the concept of the multicultural imperative, and its direct relationship to the elimination of health disparities including oral health disparities.

CONCLUSIONS

It is essential that oral health professionals strive to become culturally and linguistically proficient in communicating with and caring for all our patients. Members of professional organizations and academic institutions can also work to ensure that both students and current practitioners have access to a curriculum and continuing education with the intended outcome of increased cultural proficiency.

Interdisciplinary health promotion: a call for theory-based interventions drawing on the skills of multiple disciplines

Promoting the health of populations demands the adoption of a perspective exploring the societal, political, community, family and individual determinants of health. I will argue that to develop interventions to modify health-related behaviours and health risks requires collaboration with a range of disciplines, in order to draw upon their theoretical, empirical and oftentimes political knowledge. To illustrate this thesis, I will draw upon research in three areas: improving oral health-related behaviours in individuals with periodontal disease and childhood caries; encouraging early recognition in head and neck cancer; and managing dental anxiety. Reviews of oral health education in the early 1990 s suggested that approaches based on education were largely ineffective in the absence of the provision of fluoride supplementation. More recently, high-quality research has identified simple, theory-based interventions that can improve adherence to specific oral hygiene-related behaviours. Similarly, a range of studies have demonstrated the effectiveness of motivational interviewing for targeting caries-related behaviours in targeted groups. Dental anxiety remains a significant barrier to the uptake of dental services, and again, by working in multi-disciplinary teams, a proportionate and comprehensive range of interventions can be adopted to alleviate the burden of dental fear. Finally, head and neck cancer has potentially serious effects for sufferers, but often presents late for a variety of reasons. Through developing a theoretical model of help-seeking behaviour, psychologists have been able to identify targets for interventions and work together with the healthcare team to develop these.

Self-efficacy and oral hygiene beliefs about toothbrushing in dental patients: a model-guided study

Building on previous research on psychosocial variables associated with oral hygiene behavior, this study examined the ability of Health Belief Model variables (perceived benefits, barriers, susceptibility, severity) and self-efficacy beliefs about toothbrushing to inform prevalence of dental caries and toothbrushing frequency. To accomplish this goal, a sample of 125 dental patients completed self-report questionnaires and provided data on demographic and behavioral factors. A path analysis model with manifest variables was tested. Oral hygiene beliefs emerged as a multidimensional construct. Results suggested that stronger self-efficacy beliefs (β = .81) and greater perceived severity of oral diseases (β = .18) were related to increased toothbrushing frequency, which in turn was associated with better oral health status, as indicated by the total number of decayed, missing, and filled teeth due to dental caries (β = -.39). Possible strategies for improving oral health are discussed.

Prevention and therapeutic approaches to gingival inflammation

The most important preventive and therapeutic effort to reduce inflammation is to remove the dental plaque thoroughly. Oral self-care is thus of crucial importance to achieve and maintain oral health. There is a scarcity of scientific evidence on the most effective models for behavioural change aimed to improve oral hygiene. There is a need for randomized-controlled trials, based on behavioural sciences and performed with great methodological rigour, to investigate the usefulness of these proposed behavioural changes. Oral hygiene regimens for patients with natural teeth as well as dental implants should include brushing twice daily, inter-dental cleaning once daily and rinsing with efficient rinses as an adjunct to mechanical infection control. Power toothbrushes are preferable as they are more effective than manual toothbrushes. Inter-dental brushes seem to be most effective and useful for inter-dental cleaning. Scaling and root planing is effective in reducing inflammation and probing depths in patients with periodontitis.

Self reported dental health attitude and behavior of dental students in India

The aim of the present study was to evaluate the oral health attitudes and behavior of undergraduate dental students in India according to age, sex and level of dental education, and to compare it with those of other countries with different socioeconomic conditions. A self-administered questionnaire based on the Hiroshima University - Dental Behavior Inventory (HU-DBI) was distributed among 372 dental students at Darshan Dental College and Hospital (DDCH). The response rate was 75.8% with 44% males and 56% females. The mean HU-DBI score showed a significant relationship (P < 0.05) with age by one way-analysis of variance (ANOVA). The students were considerably concerned about the appearance of their teeth and gums and halitosis. The total mean score was not markedly higher in the clinical years (years 3 and 4) than in the non-clinical years (years 1 and 2), indicating that the students were almost equally aware. Although there were no statistically significant differences in gender and academic year for the mean score of HU-DBI, the present study showed that dental students in India generally had poorer oral health awareness compared to several other countries. The oral health behavior of Indian dental students has to be improved in order to serve as a positive model for their patients, family, and friends.

Multicultural issues in oral health

Demographic changes over the coming decades will heighten the challenges to both the dental profession and the nation. The expected growth in the numbers of racial and ethnic minorities and the concomitant growth of immigrant populations are likely to lead to worsening of oral health disparities. Their consequences are becoming increasingly evident, as the profession strives to improve the oral health of all Americans. The increasing diversity of the population, together with the importance of cultural beliefs and behaviors that affect health outcomes, will require ways to enhance provider-patient communications and oral health literacy. One important means by which to promote oral health in diverse populations is to develop a dental workforce that is both culturally and linguistically competent, as well as one that is as culturally diverse as the American population.

Verifiable CPD paper: factors that influence the dental attendance pattern and maintenance of oral health for people with multiple sclerosis

OBJECTIVE

To determine the impact of multiple sclerosis (MS) on patient attendance at dental practices and maintenance of oral health.

DESIGN

A cross-sectional postal questionnaire-based study.

SETTING

Leicestershire, United Kingdom.

SUBJECTS AND METHODS

People with MS in Leicestershire identified from local health authority records (n = 476).

MAIN OUTCOME MEASURES

Number registered at dental practice, frequency of attendance, issues and perspectives relating to attendance and maintenance of oral health.

RESULTS

A response rate of 61% (n = 289) was obtained. When compared to the general population, a higher number of people with MS were registered with a dentist (49%:88%) and displayed more frequent practice attendance (71%:81%) in the past year. People with MS reported difficulties in attending a dentist and maintaining oral health, which were exacerbated by deterioration in general health. Problems relating to reduced personal mobility had the greatest impact on attendance.

CONCLUSIONS

MS has a negative impact on perceived patient attendance and maintenance of oral health. Patients with a progressive disability could benefit greatly from the provision of preventive oral health care. The importance of seeking care earlier rather than later needs to be emphasised to both professionals and patients alike. Further efforts are required to increase awareness of the importance of oral health to the quality of life of people with MS and ensure that individuals with physical disabilities receive the same access to dental services as the able-bodied.

Stress, oral health behaviour and clinical outcome

OBJECTIVE

Several studies indicate that stress adversely affects various health behaviours. Oral hygiene behaviour, however, has been rarely studied in this context. The present study thus aims to assess the effects of stress on oral hygiene behaviour and clinical outcome.

DESIGN

In a prospective matched controlled design 12 pairs of medical students, each consisting of 1 student participating in a major academic exam and 1 student not participating in any exams (control) were studied.

METHODS

A professional tooth cleaning was performed 4 weeks prior to exams to obtain plaque levels of 0 at all sites. Immediately prior to professional tooth cleaning and 4 weeks after exams plaque levels (as indicator of oral hygiene behaviour) and bleeding on probing (an indicator of gingivitis) were assessed.

RESULTS

No group differences were observed at the beginning of the exam period; after exams significant higher rates of plaque (p=.0005, d=1.74) and gingivitis (p=.016, d=1.01) were observed in exam students as compared with controls.

CONCLUSIONS

The study illustrates the clinical significance of stress effects on health behaviour. Stress should be included as a factor in models of patient compliance and health behaviour.

Relationship between attitudes toward oral health at initial office visit and compliance with supportive periodontal treatment

OBJECTIVES

The objectives of the present study include investigation of the relationship between attitudes and desires with respect to oral health at initial office visit and compliance with supportive periodontal treatment (SPT) and identification of prognostic factors with respect to low-compliance with SPT.

MATERIALS AND METHODS

Four hundred thirty-one patients were evaluated. Subjects completed a questionnaire concerning attitude and desire with respect to oral health and subjective symptoms prior to periodontal treatment. Survival probabilities of SPT were estimated by the Kaplan-Meier method and compared between answers for each item of the questionnaire via the Cox-Mantel test. Finally, a multivariate Cox proportional hazards regression model was constructed, which included age and gender.

RESULTS

Greater than 95% of participants desired toothbrushing proficiency and lifelong retention of teeth at the initial office visit; however, the overall survival probabilities of SPT were only 52.7% after about 5 years. Patients exhibiting unfavourable attitudes toward oral health at the initial office visit, in comparison with those displaying favourable attitudes, exhibited greater tendency to abandon SPT. A Cox regression model revealed that lack of brushing on the gingival margin, non-use of an inter-dental brush or dental floss, non-use of fluoride toothpaste and frequent consumption of sugar-containing drinks were significant independent prognostic factors for low-compliance with SPT (p<0.05; Hazard ratios=2.27, 2.00, 2.56 and 2.06, respectively).

CONCLUSIONS

Desire for satisfactory oral health is not related consistently to continuation of SPT. Unfavourable attitudes toward oral health were correlated to low-compliance with SPT. Clinicians may wish to establish methods for improvement of patient compliance employing behavioural approaches applicable to the attitudes of potential low-compliance individuals.

Attitudes to and perceptions of oral health and oral care among community-dwelling elderly residents of Stockholm, Sweden: an interview study*

The aim of this study was to document perceptions of oral health of community-dwelling elderly people and how it had been affected through life. Twelve individuals (mean age 78.2 years) were gradually recruited to an interview study. The interviews were conducted as conversations, and the topics in a guide model were introduced only if they did not arise spontaneously. The interviews lasted 60-90 min and were tape-recorded and transcribed verbatim and analysed by the phenomenological-hermeneutic method. The interviews dealt with perceptions of growing old, life style, general health, former dental experiences, dental care in adult life, current oral health, general medical care, dental care, oral hygiene, dental hygienist care and the level of participation in treatment decisions. The interviewees were generally satisfied with their present oral health and often referred to their parents' oral problems as deterrents. Dental experiences from childhood, in association with the welfare state and personal financial security, were factors which influenced attitudes and perceptions of oral health and oral care. Although dental care was regarded as very expensive, it had been given priority over other expenses in adult life. The results confirm that the dental hygienist must take into account the importance of oral health to well being in old age and be aware that in elderly people, perception of personal oral health is multifactorial, influenced by life-long experience.

Therapeutic compliance methodologies in HIV-infection treatment: A comparative study

Compliance with HIV treatment has been studied extensively. Following the introduction of tritherapy, its importance and implications have changed. Antiretroviral treatments entail taking up to 20 pills a day at set hours, for which there are often numerous undesirable and even toxic side effects. These therapeutic constraints lead to what is labeled greater or lesser compliance. Certain factors such as side effects, modes of contamination, and trust in physicians appear to be more closely linked to noncompliance than others. A recurring problem is how to assess this compliance. There are two types of measures that serve this purpose: direct (biological) or indirect (interviews, questionnaires). It is often very difficult to know how authors actually proceed in assessing their patients' compliance. To determine this, we analyzed 27 of the 310 studies published between 1990 and 2000 on therapeutic compliance in HIV-infected patients. These 27 studies were not chosen because they are a statistically representative sample of the related literature, but because they account quite well for the different types of methods used to measure compliance with HIV treatment. Our analysis shows that compliance measures are quite diverse and can be either a combination of direct and indirect measures, or consist of one or more direct measures or only indirect measures. These three methodological orientations are discussed first. The limits and biases of self- and hetero-compliance assessment, so often neglected, are studied next. Finally, problems related to the temporal facet of compliance behavior are analyzed, namely definition of the concept, need for a more precise theoretical elaboration, and the place of health psychology in relation to the medical sciences.

Health beliefs in oral cancer: Malaysian estate Indian scenario

This is a study to describe the health beliefs related to oral cancer (OC) in a high-risk group in Malaysia, a predominantly Indian community living in an agricultural setting called an estate. The study population was a convenient sample of 112 adults, above 20 years of age, attending oral cancer screening in two estates. The subjects consisted of 106 (94.6%) Indians and six (5.4%) Malays. Using the Health Belief Model, the perceptions of susceptibility to OC, its severity, and the benefits of and barriers to preventive actions, as well as beliefs underlying OC aetiology were investigated. About half of the subjects (n=57, 50.9%) felt susceptible to oral cancer. A majority of subjects (n=93, 83.0%) felt that oral cancer is a severe disease. Thirty four people (30.4%) perceived OC as a preventable disease, while 56 (50%) did not, and the remaining 22 (19.6%) did not know if OC was preventable or not. The majority of subjects (84.8%) believed that modifications to the betel quid habit could be beneficial. The information solicited can be used as a starting point to design health-education activities aimed at this group in particular and the population in general.

Auto-eficácia, acúmulo de placa dental e relato de comportamento de higiene oral

O presente estudo investigou a relação de variáveis de auto eficácia com o acúmulo de placa e o relato de comportamento de higiene oral (HO). Os 94 participantes tiveram o acúmulo de placa medido, responderam a um questionário sócio-demográfico e de comportamentos de HO e escalas para a medida de auto-eficácia (AE). Os resultados indicaram que a AE percebida se correlacionou significativamente com a freqüência de escovação (rho=0,25,p=0,014) e de uso de fio dental (rho=0,40, p<0,0001). No entanto, a AE percebida não se correlacionou significativamente com a placa. A eficácia de auto-regulação (EAR) não se associou significativamente com a placa ou com o relato de comportamento de HO. São discutidas possíveis explicações para as baixas associações das variáveis de AE com a placa e da EAR com o relato de comportamento de HO.

The relationship of health beliefs and psychological mood to patient adherence to oral hygiene behaviour

Patient adherence to oral hygiene instructions (compliance) is important for the success of periodontal treatment. However, there are many different definitions and measures of what constitute patient adherence. Also, many different models of patient behaviour have been studied, with inconsistent or conflicting findings. The purpose of this study was to explore the relationships between health beliefs (three aspects of dental health locus of control, health values and adherence intent), psychological mood and periodontal outcomes. Complete periodontal data were obtained for 47 untreated patients prior to instruction in oral hygiene, and again 4-6 weeks later. Psychological variables were measured by questionnaire and adherence was measured by reductions in clinical variables (plaque and inflammation). Data were analysed using an item analysis of the questionnaire to assess the internal consistency of the subscales. The results showed overall stability in the psychological variables and reductions in the clinical variables. The main result was a series of negative associations between plaque scores and adherence intent. Inflammatory variables showed some association with psychological constructs related to dependence on external factors.
