Application of self-regulation theory and motivational interview for improving oral hygiene: a randomized controlled trial

Dynamics of Gingival Indices and Microbiological Findings During Treatment of Plaque-Induced Gingivitis in Children Aged 10-14 Years

BACKGROUND

The study analyzed the dynamics of the clinical periodontal status during the treatment of adolescents with generalized plaque-induced gingivitis.

AIM

Assessment of the predominant subgingival microflora in the case of a diagnosed inflammatory process in the gingiva in childhood.

METHODS

Full-mouth periodontal assessment of plaque accumulation and bleeding on probing with an electronic periodontal probe was performed during the treatment of 34 adolescents with generalized plaque-induced gingivitis. The treatment protocol includes five visits (1, 3, 7, 14, and 30 days). Subgingival biofilm sampling was performed by real-time PCR testing to identify, follow-up in dynamics, and determine the quantities of main subgingival periodontopathogens during treatment. Three samples per child were taken from five teeth with the most severe inflammation.

RESULTS

For children aged 10-14 years with generalized plaque-induced gingivitis, two weeks after the start of treatment, the index values for bleeding on probing decreased twice from 53 to 27%. C. gingivalis was isolated before the start of treatment in all children, followed by P. intermedia, P. micros (70,4%) and T. denticola, T. forsythia (52,9%). Representatives of the red complex according to Socransky showing greater resistance to the therapy performed in terms of frequency and amount.

CONCLUSION

The predominant subgingival microflora in adolescents with generalized plaque-induced gingivitis is representative of the orange and red Socransky complex, with index values decreasing smoothly at each subsequent visit during treatment.

Motivational Interviewing on Periodontal Treatment Outcomes: A Meta-Analysis

OBJECTIVES

This systematic review investigated the clinical efficacy of motivational interviewing (MI) in improving oral hygiene and periodontal health in patients with periodontal diseases.

METHODS

A comprehensive literature search was conducted across various databases up to May 2023. Randomised controlled trials (RCTs) evaluating the effects of MI on periodontal conditions in patients with gingivitis, periodontitis, and peri‑implantitis were included. After data screening, a risk-of-bias assessment was performed using the Cochrane risk of bias (RoB) tool. The meta-analysis was performed using random-effects models.

RESULTS

Out of 2108 records screened, 7 RCTs involving 474 patients were included in the qualitative synthesis, with 6 of these studies included in the meta-analysis. Amongst these, 5 studies had a high RoB and 2 had some concerns about bias. Although individual studies reported varied results regarding the effects of MI on different periodontal indices and parameters at different time points, the pooled results revealed no significant difference in the overall effect on plaque level, bleeding on probing, and gingival inflammation between the MI and control groups. In addition, there is insufficient evidence to suggest any significant effect on attachment loss or probing depth.

CONCLUSIONS

The current evidence is insufficient to support the effectiveness of MI as an adjunctive intervention for improving oral hygiene and periodontal outcomes. However, these results should be interpreted with caution. Additional high-quality studies with standardised MI interventions are required to derive definite conclusions.

Motivational interviewing for preventing oral morbidities in adults: Systematic review and meta-analysis

OBJECTIVE

This systematic review with meta-analysis was performed to assess whether motivational interviewing (MI) effectively prevents oral morbidities in adults.

METHODS

Studies considered were randomized controlled trials, cluster-randomized controlled trials and community-based randomized trials assessing interventions based on MI or indicating that a counselling technique based on the principles developed by Miller and Rollnick was used. Controls were any type of oral health education or negative controls. Participants were 18-60 years old. The main outcome was any oral morbidity. From 602 studies identified in MEDLINE, Scopus, Web of Science and LILACS databases, seven studies were included in the synthesis.

RESULTS

Studies included only evaluated periodontal outcomes, no studies were found for other oral morbidities. Patients' mean age was 43.7 years, and the follow-up time after MI or MI-based intervention varied between 1 month and 1 year. The total study population was 272 people with moderate-to-severe periodontitis; other groups analysed were pregnant women (n = 112) and patients with mental disorders and alcohol problems (n = 60). Meta-analysis for the plaque index (four studies, n = 267), bleeding on probing (two studies, n = 177) and gingival index (two studies, n = 166) were carried out. The summary effects for the random-effects model were estimated respectively as -3.59 percentage points (CI: [-11.44; 4.25] for plaque index, -6.41 percentage points (CI: [-12.18, -0.65]) for bleeding on probing and -0.70 (CI: [-1.87; 0.48]) for gingival index, marginally favouring the MI group. The reduced number of studies, the non-disclosure of some aspects of the data and the heterogeneity among them undermine the precision of the estimates.

CONCLUSION

The current evidence available is limited to periodontal outcomes, and it is not possible to determine whether MI effectively prevents oral morbidities in adults.

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.

Health Coaching-Based Interventions for Oral Health Promotion: A Scoping Review

Background: Health coaching-based interventions can support behaviour change to improve oral health. This scoping review aims to identify key characteristics of health coaching-based interventions for oral health promotion. Methods: The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist and the Joanna Briggs Institute manual for evidence synthesis were used in this review. A search strategy using medical subject heading terms and keywords was developed and applied to search the following databases: CINAHL, Ovid, PubMed, Cochrane Library and Scopus. Thematic analysis was used to synthesise the data. Results: Twenty-three studies met the inclusion criteria and were included in this review. These studies were predominantly based on health coaching and motivational interviewing interventions applied to oral health promotion. The following are the characteristics of health coaching-based interventions extracted from themes of the included studies: (a) Health professionals should be trained on the usage of motivational interviewing/health coaching interventions; (b) oral health professionals should acquire motivational techniques in their practice to engage patients and avoid criticisms during the behaviour change process; (c) routine brief motivational interviewing/health coaching intervention sessions should be introduced in dental clinics; (d) traditional oral health education methods should be supplemented with individually tailored communication; and (e) for cost-effectiveness purposes, motivational interviewing/health coaching strategies should be considered. Conclusions: This scoping review reveals that health coaching-based techniques of health coaching and motivational interviewing can significantly impact oral health outcomes and behaviour change and can improve oral health professional–patient communication. This calls for the use of health coaching-based techniques by dental teams in community and clinical settings. This review highlights gaps in the literature, suggesting the need for more research on health coaching-based intervention strategies for oral health promotion.

A psychological intervention for caries active young adults, a randomized controlled trial

Objective

The aim of the present study was to evaluate the effect of a brief version of the behavioral intervention Acceptance and Commitment Therapy (ACT) on reducing gingivitis and plaque levels after 18 weeks.

Materials and methods

One hundred thirty‐five caries‐active young adults (18–25 years of age), recruited from two public dental clinics, participated in this parallel group randomized control trial (RCT). Participants in the intervention (n = 67) received two ACT sessions in combination with standard information on oral health, and participants allocated to the control group (n = 68) received standard information only. Gingivitis and plaque levels were recorded at baseline and at the 9‐ and 18‐week follow‐ups. The effect of the intervention versus standard information alone was analyzed by intention‐to‐treat and per protocol, applying the General Linear Model (GLM). Exploratory analyses for the intervention and control groups were conducted to evaluate the effect of gender and smoking habits on the gingivitis and plaque outcome. The CONSORT guidelines for RCT were followed.

Results

A significant decrease in gingivitis and plaque levels was observed over time, irrespective of treatment allocation. However, the ACT intervention was not significantly more effective at reducing gingivitis and plaque scores than standard information alone, even though the intervention participants had maintained their improvement to a greater extent. The exploratory analysis revealed that females improved their gingivitis and plaque levels significantly more than the males in the intervention group (p = 0.025 for gingivitis and p = 0.013 for plaque).

Conclusion

A brief ACT intervention was not proven to be more effective than standard information alone at improving oral health in a sample of young adults with poor oral health. However, ACT seems to have a positive effect on oral health among females. (TRN ISRCTN15009620).

A health promotion intervention to improve oral health of prisoners: results from a pilot study

Purpose

Prisoners have poorer oral health than the general population. Good oral health is essential for both social and physical well-being. For prisoners, poor oral health is also related to drug use after release, whereas good oral health is related to successful reintegration into society. The purpose of this study was twofold: to examine the effect of an intervention based on motivational interviewing (MI) on prisoners’ oral health-related behavior and to assess if the intervention is a good fit for this population.

Design/methodology/approach

In total, 16 prisoners in a Norwegian prison were offered a brief MI-based intervention focusing on changing their oral health-related behavior. An oral examination was also performed and the prisoners received a small package containing oral hygiene aids. Two weeks later, a second oral examination and a semi-structured interview were conducted to explore the effect of the intervention and examine the prisoners’ responses to the intervention. Qualitative data analyzes were guided by thematic analysis.

Findings

The findings indicate that the intervention had positive effects on both the prisoners’ motivation to use oral health-related behavior and their performance of oral health-related behavior. The findings also indicate that the intervention was well adapted to the target population.

Originality/value

This is one of the first studies that explore the effect of an intervention in improving prisoners’ oral health and bridges a knowledge gap in the literature. The findings may increase the understanding of how dental services should be organized and offered to provide dental health care to this vulnerable group.

Periodontal health education session can improve oral hygiene in patients with gingivitis: A masked randomized controlled clinical study

BACKGROUND

The aim of this clinical trial was to evaluate the effect of a periodontal health education session (PHES), which included education on the pathogenesis and consequences of periodontal diseases on oral hygiene motivation in patients with gingivitis.

METHODS

A randomized controlled clinical trial was conducted on 50 (26 females and 24 males) patients with gingivitis who underwent periodontal treatment. Subjects were randomly allocated into the PHES group (experimental group) and standard oral hygiene education group (control group). The Rustogi Modified Navy Plaque Index (RMNPI) and Papillary Bleeding Index (PBI) were used to evaluate oral hygiene at baseline and were repeated after 1, 3, and 6 months. Knowledge about periodontal disease was measured and the participants' motivation was determined using the Oral Hygiene Motivation Scale.

RESULTS

Although baseline knowledge levels and motivation scores were not different between the groups, following the educational motivational interviewing (MI) session, levels were higher in the experimental compared with the control group. The subjects' RMNPI and PBI scores at the 1-, 3-, and 6- month re-examinations were statistically higher in the control group than the experimental group. Furthermore, the level of knowledge and intrinsic and total motivation scores were moderately positively correlated with a reduction in clinical indices at 6 months compared with baseline.

CONCLUSIONS

The results of this study indicated that increased knowledge and awareness about periodontal diseases and its consequences, including systemic effects, via educational MI session increased intrinsic motivation and improved oral hygiene of patients with gingivitis, especially regarding interproximal surfaces.

The Effect of a Personalized Oral Health Education Program on Periodontal Health in an At-Risk Population: A Randomized Controlled Trial

While periodontal disease is associated with many risk factors, socioeconomically disadvantaged communities experience the highest disease burden. The aim of this study was to evaluate the effectiveness of a personalized oral health education program, in combination with routine dental treatment, in participants from a low socioeconomic community. We used a randomized, controlled, examiner-blinded clinical trial. A total of 579 participants (aged 18–60 years) were randomly grouped: the intervention group (n = 292) received a personalized oral health education program in combination with routine dental care and the control group (n = 287) received routine dental care. All participants were assessed for improvement in oral health care behaviors, dental plaque, and periodontal status at baseline, 12 months, and 24 months. We found a significant drop (p < 0.001) in the plaque indices, Periodontal Probing Depths (PPD) and Bleeding on Probing (BOP) between baseline and the 12-month follow-up for both groups. For BOP, the number of sites positive was significantly different between baseline and the 24-month follow-up (p = 0.037). No differences were found between the two groups for any evaluated clinical outcome. The personalized oral health education program used in the current study did not appear to add significant improvement to clinical outcomes of periodontal health compared with routine restorative dental care per se.

Effect of a motivational video on flossing behaviour: A pilot study

OBJECTIVES

Motivational interviews used for health behavioural change requires several sessions and expert consultations. A practical method is needed to promote oral hygiene habits. The aim of the study was to develop a video as a new motivational intervention method combining several health behaviour change theories to improve flossing behaviour.

METHODS

A questionnaire about individual psychosocial characteristics was conducted to 30 volunteer dental patients. Plaque index (PI) scores were calculated and a video about flossing was shown the patients. The second PI measurements were performed after 2 months. The video including flossing instructions and expressions of performers acting dental patients was produced to test as a motivational method. Cues used in the video were generated according to health behaviour change theories and models under the supervision of an expert team. Content validity ratio (CVR) and content validity index (I-CVI) of the video and reliability of the questionnaire was determined. First and second PI scores were compared to assess the effect of the video. Correlation between answers of the questionnaire and PI changes were tested.

RESULTS

The average I-CVIs of the video was 0.93, CVR of video items was 1, I-CVIs of 5 items was 80% and of 10 was 100%. Cronbach's alpha of the questionnaire was 0.93. PI scores significantly decreased after 2 months (p < 0.001).

CONCLUSION

A single session motivational intervention via a video based on health psychological models and theories was efficacious in improving oral hygiene and flossing behaviour in the short term.

The effect of a behavioural management tool in adults with mild to moderate periodontitis. A single-blind, randomized controlled trial

OBJECTIVE

To compare a behavioural management program (test) to a standard communication approach (control) to reduce plaque, improve clinical outcomes and patient's compliance with oral self-care.

BACKGROUND

Since psychological factors affect oral health-related behaviours, approaches directed at changing behaviours and improving compliance might improve the effect of oral health education.

MATERIALS AND METHODS

This was a randomized, single-blind, parallel-design trial involving 71 patients with mild to moderate periodontitis. During a run-in period, all participants began using a power toothbrush. Two sessions of non-surgical periodontal therapy were performed post-baseline, along with one of the two oral healthcare communication approaches. Plaque and bleeding scores, probing pocket depth (PPD) and clinical attachment level (CAL) were recorded at the screening visit, baseline visit and at 8 and 14 weeks post-baseline. Patients were asked to fill in oral self-care diaries. Experience questionnaires were administered to both clinicians and patients to assess subjective experience of the clinician-patient interactions during the visits.

RESULTS

In both groups, a significant reduction in plaque and bleeding scores was observed from baseline to 8 weeks after baseline, which then remained stable at week 14, but no differences between the groups were noted. An improvement in CAL and PPD was recorded at week 8 post-baseline in the test compared to the control group. No inter-group differences in the clinician's and subject's experience questionnaires were observed.

CONCLUSION

Both approaches significantly promoted periodontal health. However, changing lifestyle requires repeated communication/engagement over time and a behavioural management program based upon two visits did not provide additional benefit compared to a standard approach.

GoPerio - impact of a personalized video and an automated two-way text-messaging system in oral hygiene motivation: study protocol for a randomized controlled trial

Background

Oral hygiene is of paramount importance for the preservation of oral health, and for patients affected by periodontal disease establishing an effective oral hygiene routine is the first step of therapy. Several clinical frameworks have been developed to foster behavior change, such as motivational interviewing. However, two obstacles can be identified. First, patients tend to forget the advice they were given during the consultation. Second, it is hard to maintain motivation in the long term, thus leading to relapse. An innovative eHealth solution was designed with the aim to tackle both obstacles and supplement the current clinical standard of care. The primary objective is to compare the full mouth plaque scores of study groups (eHealth plus standard of care versus standard of care only) at 8 weeks of follow up. The main secondary objective is to compare the full mouth bleeding score at 8 weeks of follow up.

Methods/design

The “GoPerio” study is a multicenter, randomized, controlled trial assessing the impact of a novel eHealth concept for oral hygiene motivation (personalized video of oral hygiene routine available for the patient via a cloud server plus interactive text messages) in addition to the current standard of care (motivational interviewing plus tooth scaling and polishing). The minimum sample size required is 86 patients. Participants will be randomized (allocation ratio 1:1): test group (eHealth plus standard of care) versus control group (standard of care only). The primary outcome is oral hygiene as measured by the full mouth (six sites per tooth) plaque control record (PCR) index. The main secondary outcome is gingival inflammation as measured by the full mouth (six sites per tooth) bleeding on probing (BOP) index. Both the primary and the main secondary outcomes are evaluated by blinded and calibrated examiners at 8 weeks of follow up. The other secondary outcomes are patient satisfaction and patient behavior change and motivation.

Discussion

The study will investigate the value of an innovative eHealth approach to strengthen patient motivation for oral hygiene. If proven effective, such an approach would supplement the current clinical standard of care, resulting in improved clinical outcomes with negligible impact on productivity in a dental practice.

Perioperative changes in knowledge and attitude toward oral health by oral health education

OBJECTIVES

Perioperative oral health care can prevent postoperative complications, but it is also important to maintain oral health afterward to avoid later adverse events. This study examined (a) the relationship between knowledge and attitude toward oral health (KAOH) and oral/periodontal status (OPS) in patients receiving surgery, and (b) the changes in KAOH by perioperative oral health care and education.

METHODS

Patients receiving surgery who visited our hospital's dental clinic beforehand were prospectively recruited. All participants received oral health care and education. In questionnaires assessing KAOH before and after surgery, respondent answers were generally classified as positive or negative. OPS was assessed before surgery. Associations between KAOH and OPS and perioperative changes in KAOH were statistically tested.

RESULTS

A total of 507 patients answered the questionnaire before surgery, among whom 324 patients also completed it afterward. Preoperative OPS was significantly worse in the negative than in the positive KAOH group. Positive answers for KAOH increased significantly from 68.6% to 92.2% during the perioperative period.

CONCLUSIONS

We found that patients with poor KAOH also had poor OPS, but KAOH could be improved by perioperative oral health care and education, suggesting that perioperative oral health management could improve oral health knowledge and attitudes.

The role of psychological theories in oral health interventions: A systematic review and meta-analysis

OBJECTIVE

In the present study, we attempted to assess how psychological theories (health belief model [HBM], theory of planned behaviour [TPB], social cognitive theory [SCT], clinical theories [CT] and other theories [OT]) influence oral health interventions.

METHODS

PubMed, Scopus, Cochrane and Web of Knowledge databases from 2000 to 2017 were searched. We defined psychological theories based on five subgroups: (A) HBM, (B) TPB, (C) SCT, (E) CT and (F) OT.

RESULTS

From the 156 identified studies, 19 studies based on PICO were included. Our findings indicated that the standardized mean difference (SMD) of HBM was 0.37 (95% CI: 0.24, 0.51), which was statistically significant in improving oral health. The SMD of SCT was not significant (0.05 [95% CI: -0.33, 0.44]) in improving oral health. The SMD of TPB was significant (1.66 [95% CI: 1.06, 2.27]) in improving oral health. The SMD of CT (-4.6 [95% CI: -6.49, -2.71]) and OT (2.93 [95% CI: 1.55, 4.32]) revealed significant differences in improving oral health.

CONCLUSION

The current meta-analysis showed that in general, psychological interventions that used OT, CT, HBM and TPB were effective in enhancing oral health status, and interventions that used SCT did not have an effect on improving oral health status. Oral health care providers who work with patients to take methods and improve behaviours that are related to appropriate oral health need to comprehend their applicability and strengths.

Characteristics of dental patients determining their compliance level in dentistry: relevance for predictive, preventive, and personalized medicine

This article centers on the relationship between psychological specifics of dental patients and their adherence to treatment. It describes clinical and personality specifics of periodontal patients and presents personality characteristics of patients with positive and negative dynamics of the therapy, as well as patients without periodontal diseases. The study findings highlight the importance of building confidential relationships with the patient and the need for a client-oriented approach to developing treatment plans and strategies for different types of dental patients. In the future, based on the study results, we find it necessary to elaborate more specific criteria for assessing personality characteristics of patients which determine their ability to comply with the doctor's recommendations. The dentist should not expect the success of their work without applying individual psychological approach to each particular patient. This knowledge means to help in further prognosis of the prescribed treatment and also can make the treatment more personalized and prevent non-compliance complications.

Behavioural interventions that have the potential to improve self-care in adults with periodontitis: a systematic review

AIM

To evaluate behavioural and educational interventions used to improve self-care in adult periodontitis patients in comparison with conventional instruction.

METHODS

A systematic electronic search of empirical studies that were published up to June 2017 using the MEDLINE database was performed. The reference lists of all of the included studies and articles from six separate journals were manually searched.

RESULTS

A total of 1806 articles were identified. Six articles fulfilled the inclusion and exclusion criteria. The interventions used in periodontal treatment had theoretical backgrounds of cognitive behavioural approach, self-regulation theory of Leventhal, motivational interviewing and a client self-care commitment model. The control group in each study was described receiving conventional information. The outcomes of the interventions were classified into three categories: 1) clinical findings 2) self-reported self-care and 3) patient evaluations of the intervention. The behavioural intervention groups seemed to perform slightly better than the control groups when clinical outcome measures such as the presence of plaque or number of periodontal pockets were used. Furthermore, behavioural interventions increased patient reported compliance (e.g. effectiveness of self-care and frequency of interdental cleaning). The different behavioural techniques all seemed to work more effectively than conventional instruction. No behavioural technique could be identified superior to the other.

CONCLUSIONS

The behavioural interventions seem to be beneficial for patient adherence and may therefore improve periodontal treatment success. However, there is a need to further explore the use of different methods in studies with larger sample sizes, longer follow-up times and both behavioural and clinical outcome measures.

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.

Can a brief psychological intervention improve oral health behaviour? A randomised controlled trial

Background

Dental caries is a major public health issue affecting a large proportion of the general population. The disease is associated with behavioural factors and is thus preventable to a high degree. Individuals may need assistance to be able to change their oral health behaviour. There is a lack of such interventions for adults affected by severe caries. The aim of the study was to evaluate the effect of Acceptance and Commitment Therapy (ACT), a form of cognitive behavioural therapy, on oral health behaviour in young adults with poor oral health.

Methods

The study included a two group parallel randomised controlled trial at general dental clinics, with young adults, 18–25 years of age, ≥ two manifest proximal dental caries lesions (n = 135); 67 were treated with ACT and 68 with standard disease information only, respectively. Primary outcomes: oral health behaviours (tooth-brushing, flossing, use of toothpicks, and additional fluoride use). The CONSORT principles for RCTs were used, including intention-to-treat and per protocol analyses. The Chi-square, Mann-Whitney, and Wilcoxon Signed Rank tests were applied, including effect sizes.

Results

The study groups did not differ with regard to oral health behaviour variables at baseline. The intervention group improved all their oral health behaviours significantly over time (effect sizes, 0.26–0.32), while the control group showed improved behaviours on two measures (flossing and additional use of fluoride, effect sizes, 0.22–0.23).

Conclusions

By testing a psychological intervention on young adults (18–25 years of age) with a high prevalence of caries, we found an immediate positive effect with improved oral health behaviours.

Effective strategies to motivate nursing home residents in oral care and to prevent or reduce responsive behaviors to oral care: A systematic review

BACKGROUND

Poor oral health has been a persistent problem in nursing home residents for decades, with severe consequences for residents and the health care system. Two major barriers to providing appropriate oral care are residents' responsive behaviors to oral care and residents' lack of ability or motivation to perform oral care on their own.

OBJECTIVES

To evaluate the effectiveness of strategies that nursing home care providers can apply to either prevent/overcome residents' responsive behaviors to oral care, or enable/motivate residents to perform their own oral care.

MATERIALS AND METHODS

We searched the databases Medline, EMBASE, Evidence Based Reviews-Cochrane Central Register of Controlled Trials, CINAHL, and Web of Science for intervention studies assessing the effectiveness of eligible strategies. Two reviewers independently (a) screened titles, abstracts and retrieved full-texts; (b) searched key journal contents, key author publications, and reference lists of all included studies; and (c) assessed methodological quality of included studies. Discrepancies at any stage were resolved by consensus. We conducted a narrative synthesis of study results.

RESULTS

We included three one-group pre-test, post-test studies, and one cross-sectional study. Methodological quality was low (n = 3) and low moderate (n = 1). Two studies assessed strategies to enable/motivate nursing home residents to perform their own oral care, and to studies assessed strategies to prevent or overcome responsive behaviors to oral care. All studies reported improvements of at least some of the outcomes measured, but interpretation is limited due to methodological problems.

CONCLUSIONS

Potentially promising strategies are available that nursing home care providers can apply to prevent/overcome residents' responsive behaviors to oral care or to enable/motivate residents to perform their own oral care. However, studies assessing these strategies have a high risk for bias. To overcome oral health problems in nursing homes, care providers will need practical strategies whose effectiveness was assessed in robust studies.

Motivational Interviewing As an Adjunct to Periodontal Therapy-A Systematic Review

Aim: Periodontal therapy is highly dependent on a patient's long-term adherence with regard to oral hygiene, diet, and regular check-ups at the dentist. Motivational Interviewing (MI) is a client-centered, directive method for encouraging a patients' behavioral health change. The aim of this systematic review was to reveal the effects of MI as an adjunct to periodontal therapy.

Methods: Three databases (PubMed, Cochrane Library, and Web of Science) were reviewed for randomized controlled clinical trials. Articles were included when using MI as an adjunct to periodontal therapy and presenting clinical periodontal and oral hygiene related parameters. Two authors independently coded the relevant articles.

Results: The search yielded 496 articles. After analysis and exclusion, a total of five papers could be included. The quality of the articles ranged between 72–88%. The two independent raters showed a high inter-rater reliability (Cohens-Kappa = 0.89). In two studies MI showed a significant positive effect on bleeding on probing and plaque values. One study showed improvement of self-efficacy in interdental cleaning. Two studies showed no influence of MI on periodontal parameters of the patients.

Conclusion: The use of MI as an adjunct to periodontal therapy might have a positive influence on clinical periodontal parameters (plaque values, gingival, and periodontal inflammation) and psychological factors related to oral hygiene (self-efficacy). Due to the low body of evidence further studies are needed. Future studies should include fidelity measures of the applied MI, a high number of counselors, several MI sessions, and long-term study follow-up to show potential effects.

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.

Psychological Interventions for Poor Oral Health

The aim of this systematic review and meta-analysis was to study the effectiveness of psychological interventions in adults and adolescents with poor oral health. The review follows the PRISMA guidelines for systematic reviews. The PICO format (population, intervention, comparison, and outcome) was used to define eligible studies. The populations were adults or adolescents (≥13 y of age and independent of others) with poor oral health (defined as dental caries, periodontal disease, and/or peri-implantitis). The interventions were psychological and/or behavioral models and theories, in comparison with traditional oral health education/information. The primary outcomes were dental caries, periodontitis, gingivitis, and peri-implantitis. Secondary outcomes were dental plaque, oral health–related behavior, health-related quality of life, health beliefs and attitudes, self-perceived oral health, and complications/risks. The systematic literature search identified 846 articles in December 2013 and 378 articles in July 2015. In total, 11 articles on 9 randomized controlled trials were found to meet the inclusion criteria. These reported on adults with periodontal disease, and several used motivational interviewing (MI) as their mode of intervention. The CONSORT guidelines and the GRADE approach were used for study appraisal and rating of evidence. The meta-analysis showed no statistically significant differences in gingivitis or plaque presence. In addition, a meta-analysis on MI compared with education/information found no statistically significant differences in gingivitis presence. Only 1 meta-analysis—on psychological interventions versus education/information regarding the plaque index—showed a small but statistically significant difference. There were also statistically significant differences reported in favor of psychological interventions in oral health behavior and self-efficacy in toothbrushing. However, the clinical relevance of these differences is difficult to estimate. The certainty of evidence was low. Future research needs to address several methodological issues and not only study adults with periodontal disease but also adolescents and patients with dental caries and peri-implantitis.

Face-to-face individual counseling and online group motivational interviewing in improving oral health: study protocol for a randomized controlled trial

BACKGROUND

Motivational interviewing (MI) has great potential in changing health-related behaviors. In addition to delivery in face-to-face individual counseling, MI can be delivered through online groups, a method that is particularly appealing to adolescents and may offer several benefits. This randomized controlled trial compares the effectiveness of prevailing health education (HE), face-to-face individual MI and online group MI in improving adolescents' oral health behaviors (diet and toothbrushing) and in preventing dental caries and periodontal diseases.

METHODS/DESIGN

In each of Hong Kong's main districts (Hong Kong Island, Kowloon and the New Territories), three secondary schools will be recruited and randomly assigned to three groups (HE, face-to-face individual MI, and online group MI). A total of 495 adolescents (aged 12 to 13 years) with unfavorable oral health behaviors ("snacking twice or more a day" and/or "brushing teeth less than twice a day") will be recruited: 165 in each group. Two dental hygienists will be trained to deliver the interventions. HE will be provided through an oral health talk. Participants in the "face-to-face individual MI" group will join a one-on-one counseling session. For "online group MI," participants will form groups of 6 to 8 and join a synchronous text-based online counseling session. At baseline and after 6, 12 and 24 months, clinical outcomes (caries increment and gingival health) and oral health self-efficacy and behaviors (toothbrushing and snacking) will be recorded through an oral examination and a questionnaire, respectively. Effectiveness of the interventions will be evaluated and compared. The primary outcomes will be the "number of new carious surfaces" and "gingival bleeding score" (% of surfaces with gingival bleeding). The secondary outcomes will be changes in oral health self-efficacy and behaviors (toothbrushing and snacking frequencies). A preliminary economic evaluation and a process evaluation will be included to analyze the cost of the interventions and the interactions in MI sessions.

DISCUSSION

Since online group MI is expected to be more convenient, accessible, and time efficient, it might address the practicality issues and pave the way for the application of MI in dental practice. The findings will assist public health workers and dental practitioners to choose effective and viable approaches in delivering behavioral interventions. Since unhealthy diet and poor personal hygiene are common risk factors accountable for many systemic diseases, the intervention scheme identified in this study can also contribute to advancing general health.

Effectiveness of motivational interviewing at improving oral health: a systematic review

OBJECTIVE

To analyze the effectiveness of motivational interviewing (MI) at improving oral health behaviors (oral hygiene habits, sugar consumption, dental services utilization or use of fluoride) and dental clinical outcomes (dental plaque, dental caries and periodontal status).

METHODS

A systematic search of PubMed, LILACS, SciELO, PsyINFO, Cochrane and Google Scholar bibliographic databases was conducted looking for intervention studies that investigated MI as the main approach to improving the oral health outcomes investigated.

RESULTS

Of the 78 articles found, ten met the inclusion criteria, all based on randomized controlled trials. Most studies (n = 8) assessed multiple outcomes. Five interventions assessed the impact of MI on oral health behaviors and nine on clinical outcomes (three on dental caries, six on dental plaque, four on gingivitis and three on periodontal pockets). Better quality of evidence was provided by studies that investigated dental caries, which also had the largest population samples. The evidence of the effect of MI on improving oral health outcomes is conflicting. Four studies reported positive effects of MI on oral health outcomes whereas another four showed null effect. In two interventions, the actual difference between groups was not reported or able to be recalculated.

CONCLUSIONS

We found inconclusive effectiveness for most oral health outcomes. We need more and better designed and reported interventions to fully assess the impact of MI on oral health and understand the appropriate dosage for the counseling interventions.

Improving oral hygiene skills by computer-based training: a randomized controlled comparison of the modified Bass and the Fones techniques

BACKGROUND

Gingivitis and other plaque-associated diseases have a high prevalence in western communities even though the majority of adults report daily oral hygiene. This indicates a lack of oral hygiene skills. Currently, there is no clear evidence as to which brushing technique would bring about the best oral hygiene skills. While the modified Bass technique is often recommended by dentists and in textbooks, the Fones technique is often recommended in patient brochures. Still, standardized comparisons of the effectiveness of teaching these techniques are lacking.

METHODOLOGY/PRINCIPAL FINDINGS

In a final sample of n = 56 students, this multidisciplinary, randomized, examiner-blinded, controlled study compared the effects of parallel and standardized interactive computer presentations teaching either the Fones or the modified Bass technique. A control group was taught the basics of tooth brushing alone. Oral hygiene skills (remaining plaque after thorough oral hygiene) and gingivitis were assessed at baseline and 6, 12, and 28 weeks after the intervention. We found a significant group×time interaction for gingivitis (F(4/102) = 3.267; p = 0.016; ε = 0.957; η(2) = 0.114) and a significant main effect of group for oral hygiene skills (F(2/51) = 7.088; p = 0.002; η(2) = 0.218). Fones was superior to Bass; Bass did not differ from the control group. Group differences were most prominent after 6 and 12 weeks.

CONCLUSIONS/SIGNIFICANCE

The present trial indicates an advantage of teaching the Fones as compared to the modified Bass technique with respect to oral hygiene skills and gingivitis. Future studies are needed to analyze whether the disadvantage of teaching the Bass technique observed here is restricted to the teaching method employed.
