Motivational interviewing to prevent early childhood caries: A randomized controlled trial

Development of Chatbot-Based Oral Health Care for Young Children and Evaluation of its Effectiveness, Usability, and Acceptability: Mixed Methods Study

Background

Chatbots are increasingly accepted in public health for their ability to replicate human-like communication and provide scalable, 24/7 services. The high prevalence of dental caries in children underscores the need for early and effective intervention.

Objective

This study aimed to develop the 30-Day FunDee chatbot and evaluate its effectiveness, usability, and acceptability in delivering oral health education to caregivers of children aged 6 to 36 months.

Methods

The chatbot was created using the artificial intelligence (AI) chatbot behavior change model, integrating behavioral change theories into content designed for 3-5 minutes of daily use over 30 days. A pre-post experimental study was conducted from December 2021 to February 2022 in Hat Yai District, Songkhla Province, and Maelan District, Pattani Province, Thailand. Fifty-eight caregivers completed a web-based structured questionnaire at baseline and 2 months post baseline to evaluate knowledge, protection motivation theory-based perceptions, and tooth-brushing practices. Usability was assessed via chatbot logfiles and a web-based questionnaire at 2 months post baseline. Acceptability was evaluated through three methods: (1) open-ended chatbot interactions on day 30, (2) a web-based structured questionnaire at 2 months post baseline, and (3) semistructured telephone interviews with 15 participants 2 weeks post intervention. Participants for interviews were stratified by adherence levels and randomly selected from Hatyai and Maelan districts. All self-reported variables were measured on a 5-point Likert scale (1=lowest, 5=highest).

Results

The chatbot was successfully developed based on the 4 components of the AI chatbot behavior change model. Participants had a mean age of 34.5 (SD 8.6) years. The frequency of tooth brushing among caregivers significantly improved, increasing from 72.4% at baseline to 93.1% two months post baseline (P=.006). Protection motivation theory-based perceptions also showed significant improvement, with mean scores rising from 4.0 (SD 0.6) at baseline to 4.5 (SD 0.6) two months post baseline (P<.001). The chatbot received high ratings for satisfaction (4.7/5, SD 0.6) and usability (4.7/5, SD 0.5). Participants engaged with the chatbot for an average of 24.7 (SD 7.2) days out of 30. Caregivers praised the chatbot's content quality, empathetic communication, and multimedia design, but noted the intervention's lengthy duration and messaging system as limitations.

Conclusions

The 30-Day FunDee chatbot effectively enhanced caregivers' perceptions of oral health care and improved tooth-brushing practices for children aged 6-36 months. High user satisfaction and engagement demonstrate its potential as an innovative tool for oral health education. These findings warrant further validation through large-scale, randomized controlled trials.

Restorative and patient factors associated with repeat general anesthesia for dental treatments in young children: A case-control study

BACKGROUND

The aim of this study was to assess factors associated with higher odds of undergoing repeat general anesthesia (GA2) for dental treatments.

METHODS

The authors studied children up to age 48 months of age enrolled in Medicaid who underwent dental treatment under first general anesthesia (GA1). The authors used a case-control design to compare children who had a GA2 within 48 months of GA1 (case patients) with those who did not (control patients).

RESULTS

In total, 60 case patients were age and sex matched to 120 control patients. Mean (SD) age at GA1 was 38 (5.2) months for case participants and 40 (4.7) months for control participants (P = .08). Higher caries involvement of maxillary incisors (P = .04), and lower caries involvment of canines (P = .003), first molars (P = .012), and second molars (P < .001) at GA1 was associated with higher odds of occurrence of GA2. There was a significant inverse association between full-coverage restoration on canines (P = .003), first molars (P = .001), and second molars (P = .002) at GA1 and occurrence of GA2. There was a significant direct association between the use of composites or sealants on second molars in GA1 and occurrence of GA2 (P = .02). The number of extractions at GA1 was not associated significantly with the occurrence of GA2.

CONCLUSIONS

The use of full-coverage restorations on primary molars and canines under general anesthesia (GA) was associated with lower odds of occurrence of GA2. Resin restorations and sealants on primary second molars were associated with higher odds of occurrence repeat GA. The findings support preferential use of full-coverage restorations for young children undergoing dental GA.

PRACTICAL IMPLICATIONS

Full-coverage restorations should be considered strongly for young children undergoing GA for dental treatments to reduce the risk of requiring GA2.

A systematic review of caries risk in children <6 years of age

BACKGROUND

For caries risk assessment (CRA) tools for young children to be evidence-based, it is important to systematically review the literature to identify factors associated with the onset of early childhood caries (ECC).

AIM

This updated systematic review aimed to identify current evidence on caries risk in young children.

DESIGN

A comprehensive and systematic literature search of relevant databases was conducted to update a previous systematic review and identify risk factors associated with ECC. Potential risk factors were identified based on strength of association using odds ratios, hazard ratios, relative risk, etc. GRADE was used for rating quality evidence through consensus.

RESULTS

Twenty-two studies met inclusion criteria for the search from mid-2017 to 2021. Twenty-five publications from the prior systematic review, from 1997 to mid-2017, were also included. Several socioeconomic, behavioral, and clinical variables were identified as ECC risk factors. Factors included the following: age, socioeconomic status, frequency of and supervised toothbrushing, fluoride exposure, breast- and bottle-feeding, feeding habits, absence of a dental home, past caries experience, active non-cavitated lesions, visible plaque, enamel defects, and microbiome.

CONCLUSION

This study provides updated evidence of risk factors for ECC that could be included in CRA tools.

Barriers to prevention in oral health care for english NHS dental patients: a qualitative study of views from key stakeholders

BACKGROUND

Despite significant progress in the control of oral diseases since the discovery of fluoride in the 1940s, dental caries and periodontal diseases continue to affect a significant proportion of the population, particularly socially disadvantaged and lower socioeconomic groups. The National Health Service in England provides preventive advice and treatments as part of an oral health assessment, and evidence-based guidance recommends the use of fissure sealants and topical fluorides in addition to dietary and oral hygiene advice. Although oral health promotion and education have become expected parts of dental care, the need for restorative treatments remains relatively high. We aimed to explore how barriers to preventive advice and treatment for NHS patients may be hindering the provision of prevention in oral health to patients from the perspectives of multiple key stakeholders.

METHODS

Semi-structured interviews and focus groups were undertaken between March 2016-February 2017 with four groups of stakeholders: dentists, insurers, policy makers and patient participants. The interviews were analysed using deductive, reflexive thematic analysis.

RESULTS

Thirty-two stakeholders participated: 6 dentists, 5 insurers, 10 policy makers, and 11 patient participants. Four themes were developed: Perspectives on the clarity of oral health messaging and patient's knowledge, The variability of prioritising prevention, Influences of the dentist-patient relationship on effective communication and Motivation to enact positive oral health behaviours.

CONCLUSIONS

The findings from this research indicate that patients' knowledge of and priority placed on prevention is variable. Participants believed that more targeted education could be valuable in enhancing these. A patient's relationship with their dentist could also influence their level of knowledge through the information shared with them, their receptivity to the preventive messages and the value they place on it. However, even with knowledge, prioritising prevention and a good patient-dentist relationship, without motivation to engage in preventive behaviour the impact of these is reduced. Our findings are discussed in relation to the COM-B model of behaviour change.

The effectiveness of motivational interviewing on the oral health of leukemic children and oral health care knowledge, attitude and practice of their mothers: a hospital-based intervention

BACKGROUND

Some studies suggest a higher effectiveness of motivational interviewing compared to common oral health instruction in healthy individuals. As regards to higher prevalence of dental diseases like early childhood caries, oral mucositis, and gingivitis are reported for leukemic children, the present study aims to compare the effectiveness of educating mothers through MI with the common instruction (CI) for the oral health of children with leukemia under six years old.

METHOD

This quasi-experimental study was designed in Tehran University of Medical Sciences, School of Dentistry and conducted on 61 mothers with leukemic children under age six hospitalized in Mahak Hospital and Rehabilitation Complex which is a Pediatric Cancer Research and Hospital Center, in 2021. Mother and child pairs were allocated to MI or CI (using pamphlets) groups. Data was collected using a questionnaire of mothers' knowledge, attitude, motivation, and practice concerning oral health care in leukemic children. The children underwent clinical examination to assess plaque index before and three months after the intervention. The data were analyzed using SPSS version 25 (IBM, Armonk, NY, USA) by ANCOVA test.

RESULTS

The preschoolers mean ages were 4.23 ± 1.41 and 4.32 ± 1.33 (ranged from 2 to 6 years old) in the MI and CI group, respectively. There were 16 girls (53.3%) and 14 boys (46.7%) in the MI group, and 15 girls (48.4%) and 16 boys (51.6%) in the CI group. Significant differences were observed in the amount of plaque index between the MI group and the CI group (0.20 ± 0.04, p-value < 0.001). A significant increase was observed in the mean of changes in scores of knowledge, attitude, motivation, mother's practice concerning child's oral health, mother's practice concerning personal oral health in the MI group (p-value < 0.001).

CONCLUSIONS

Considering that instruction using MI showed to be effective in improving oral health adherence in mothers and reducing plaque in children with Leukemia, it may be recommended as a promising method to promote the oral health of such susceptible children in places that they are constantly present for treatment.

TRIAL REGISTRATION

The study was registered in the Iranian Registry of Clinical Trials (IRCT) on 11.03.2021 (code: IRCT20131102015238N5).

Correlation of the Oral Health Scoring-based Pregnant Oral Self-Care – package (POSC-p) Model with the Motivation to Seek Oral Health Treatment in Pregnant Women

Background:

Uncomprehensive oral health evaluation instruments and measurement and the low motivation for seeking dental and oral treatment for pregnant women; all require comprehensive measurement instruments that will increase the motivation for seeking oral health treatment for pregnant women. POSC-p model was developed for the Oral Health Scoring (OHS) to assess pregnant women's perceived needs, clinical examination, and salivary state.

Objectives:

The research objective was to analyse the correlation between the POSC-p model with the motivation for seeking oral health care in pregnant women.

Methods:

Cross-sectional research was conducted by a non-probability sampling technique using the consecutive sampling method. The sample size was determined based on the correlation analysis sample size calculation formula. The study variables were POSC-p model built with three dimensions; POSC-p score section 1 was felt needs, POSC-p score section 2 was normative needs, and POSC-p score section 3 was saliva condition. In addition, motivation to seek treatment with intrinsic and extrinsic motivation dimensions. All data were analysed using the Spearman rank correlation test.

Results:

A significant correlation was found between the POSC-p model with intrinsic and a combination of treatment-seeking motivation (p=0.026); a combined score of the POSC-p model with intrinsic (p=0.008) and a combination of treatment-seeking motivation (p=0.032).

Conclusion:

There is a correlation between the POSC-p with motivation for seeking oral health treatment in pregnant women.

Motivational interviewing versus conventional caries prevention strategies in high-caries-risk children and families: a non-randomised trial

Background This study compared the effectiveness of motivational interviewing (MI) and conventional caries prevention (CCP) for primary (caries increment) and secondary outcomes (caries intensity, gingival health, caregiver-reported oral health-related knowledge, behaviours and attitudes) over 12 months.Methods High-caries-risk children and caregivers received CCP or MI with comprehensive dental care. Fidelity was monitored using MI treatment integrity code 4.2.1. Caries increment, intensity and gingival health were measured at baseline, six and twelve months. Readiness Assessment of Parents Concerning Infant Dental Decay questionnaires recorded oral health-related knowledge, behaviours and attitudes.Results In total, 86 caregiver-child dyads (CCP = 51; MI = 35) were recruited. The mean difference (95% confidence interval [CI]) in caries increment (ΔdICDAS1-6mfs + DICDAS1-6MFS) was significantly higher with MI compared to CCP at six (MI 2.3 [1.2, 3.5] vs CCP 0.6 [0.1, 1.0]; p <0.001) and twelve (MI 4.3 [2.5, 6.0] vs CCP 1.2 [0.6, 1.8]; p <0.001) months. Multivariate analysis with CCP as reference group, odds ratio (95% CI) for new/progressed caries (Δdecayed, missing and filled surface score [permanent] + decayed, missing and filled surface score [primary] >0) at six and twelve months were 18.2 (4.0, 81.7); p <0.001 and 12.6 (3.3, 47.8); p <0.001, respectively. The MI group reported positive behaviours and attitudes.Conclusions CCP was more effective in reducing caries increment when behaviour change technique was incorporated into the preventative strategies as per current paediatric dentistry guidelines.

Novel Giomers Incorporated with Antibacterial Quaternary Ammonium Monomers to Inhibit Secondary Caries

The objective of this study was to develop novel modified giomers by incorporating the antibacterial quaternary ammonium monomers (QAMs), dimethylaminododecyl methacrylate (DMADDM) or dimethylaminohexadecyl methacrylate (DMAHDM) into a commercial giomer. The material performances including mechanical properties, surface characteristics, color data, cytotoxicity and fluoride release of the novel giomers were evaluated. Antibacterial activity against severe early childhood caries (S-ECC) saliva-derived biofilms was assessed by lactic acid production measurement, MTT assay, biofilm staining and 16S rRNA sequencing. A rat model was developed and the anti-caries effect was investigated by micro-CT scanning and modified Keyes’ scoring. The results showed that the material properties of the QAMs groups were comparable to those of the control group. The novel giomers significantly inhibited lactic acid production and biofilm viability of S-ECC saliva-derived biofilms. Furthermore, caries-related genera such as Streptococcus and Lactobacillus reduced in QAMs groups, which showed their potential to change the microbial compositions. In the rat model, lesion depth, mineral loss and scoring of the QAMs groups were significantly reduced, without side effects on oral tissues. In conclusion, the novel giomers incorporated with antibacterial QAMs could inhibit the cariogenic biofilms and help prevent secondary caries, with great potential for future application in restorative treatment.

Fidelity of motivational interviewing in an oral health intervention with caregivers of young children

The aim of this study was to assess the fidelity of a motivational interviewing (MI) intervention with caregivers of young children in primary healthcare in Southern Brazil. Seven trained interventionists conducted one MI session with each caregiver at their home. The sessions were audio-recorded and a randomly selected subset (n = 109) was coded by a single reviewer using the Motivational Interviewing Treatment Integrity 3.1.1. criteria (MITI 3.1.1.). This instrument establishes parameters of MI proficiency for beginners and experts measuring the global ratings of five MI principles (evocation, collaboration, autonomy/support, direction and empathy), the global MI spirit score, and the behavior counts of MI basic skills: to inform, to ask, and to listen. The mean global MI spirit rating was 4.0 (95%CI 3.9-4.1). Mean MI principle scores ranged from 3.8 (95%CI 3.7-3.9) to 4.3 (95%CI 4.2-4.4). The overall reflection-to-question ratio was 0.9 (95 CI 0.8-1.0), % open questions was 76.3 (95%CI 73.1-79.6), % complex reflections was 66.1 (95%CI 63.1-69.1), and % MI-adherent information was 94.1 (95%CI 93.5-94.5). Interventionists with higher scores conducted more and longer sessions than those with lower scores (p = 0.012). Those with beginner proficiency had a higher proportion of caregivers changing their oral health knowledge (p = 0.005). In conclusion, a good degree of MI fidelity was found, with higher fidelity among interventionists who conducted more interviews and spent more time talking with caregivers.

Fidelity of motivational interviewing with families in high-caries-risk children

OBJECTIVES

Motivational interviewing (MI) is a promising behavioural intervention for prevention of dental caries in children. Few studies have reported on fidelity of MI delivered in dental settings. The aim of this paper is to explore the fidelity of implementing MI in a clinical dental practice setting, as part of an intervention study investigating caries-preventive effects of MI delivered to high-caries-risk children and their primary caregivers.

METHODS

Three oral health therapy clinicians trained in MI (counsellors) provided MI to high-caries-risk children and their primary caregivers. All MI sessions (n = 34) were audio-recorded and analysed using the MI Treatment Integrity code 4.2.1. Qualitative analysis of counsellor self-reflections identified barriers to MI delivery.

RESULTS

All counsellors were found to adhere to the MI process and demonstrated fair to good MI proficiency for global scores, with a mean (95% CI) of 3.3 (3.1-3.4) recorded for technical scores and 3.6 (3.5-3.8) for relational scores. The mean (95% CI) per cent complex reflections was 23% (19.4-27.1) and the mean reflection:question ratio was 0.7 (0.6-0.9). No significant differences were observed between counsellors for MI proficiency. Cultural barriers, environmental distractions, participant dental anxiety and counsellor tendency towards prescriptive advice-giving were identified by counsellors as hindrances to effective MI.

CONCLUSIONS

Motivational interviewing is a skill which requires multifaceted training, practice and mentoring to meet accepted proficiency thresholds. Monitoring of MI using a validated tool is essential to ensure delivery as intended and accurately attribute outcomes to the intervention. Dental organizations intending to implement MI for caries prevention should be aware of the demands on time and resources required to deliver proficient MI and monitor fidelity.

Parental-oriented educational mobile messages to aid in the control of early childhood caries in low socioeconomic children: A randomized controlled trial

OBJECTIVES

To evaluate the effectiveness of educational messages as an aid in the control of early childhood caries (ECC) in low socioeconomic children.

METHODS

A single-blinded, randomized, and parallel-group study was conducted with 104 dyads of parents and children aged between 36-60 months, recruited in preschools from Bauru, Brazil. The participants were randomly allocated into control and intervention groups (1:1), stratified by parental eHealth literacy scores (eHEALS) and children's caries experience. Every 2 weeks, text messages were sent to parents of intervention group via WhatsApp. Visible plaque index (VPI) and the International Caries Detection and Assessment System (ICDAS) were assessed at baseline, 3- and 6-month follow-ups, while eHEALS and dietary habits were determined at baseline and 6-month follow-up. Statistical analysis was performed to intra and intergroup comparisons through Fischer's exact and McNemar tests, and Mann-Whitney U and Friedman tests, respectively (P < 0.05).

RESULTS

Despite similarities between groups, intervention increased parental eHEALS scores, influencing the reports about the children's consumption of sugar-free sweets and controlling the severity of ECC.

CONCLUSION

Therefore, mobile text messages were effective to control the severity of ECC in low socioeconomic preschoolers, improving parental eHealth literacy and changing children's dietary patterns.

CLINICAL SIGNIFICANCE

These findings demonstrate that parental-oriented WhatsApp messages can contribute to oral health education of socioeconomic vulnerable parents towards risk behavior changes to control ECC.
