The effectiveness of behaviour change interventions delivered by non-dental health workers in promoting children’s oral health: A systematic review and meta-analysis

A Systematic Review and Meta-Analysis of Interventions Targeted to Parents for Improving the Oral Health of Children from Culturally and Linguistically Diverse (CALD) Backgrounds

A high prevalence of dental caries is a significant health problem, especially in the pediatric population. Low-income minority groups, including the refugee and immigrant populations, are at higher risk of compromised oral health. It has been suggested that migrant parents do not have enough understanding of oral health, risk factors associated with dental caries, or the progress of dental decay. This systematic review aims to study quantitative literature on oral health interventions, health promotion programs, or behaviour change interventions targeting the parents/ caregivers of culturally and linguistically diverse (CALD) children. A systematic search of electronic databases, including MEDLINE, EMBASE, PUBMED, CINAHL, SCOPUS, WEB OF SCIENCE, COCHRANE, and PROQUEST, was conducted until August 2023. Randomised (RCT) or non-randomised controlled trials (NRCTs) were included. Two reviewers independently assessed the quality of the included studies using the Cochrane Risk of Bias (RoB) 2.0 and ROBINS-I tools. Meta-analysis was performed as appropriate. The initial search from the databases retrieved 2073 articles. After the removal of duplicates, 1683 articles remained. Finally, 69 articles were reviewed in full text, and 15 articles were considered eligible in this review. The RoB assessment for RCTs rated three as low-risk and three as high-risk. The serious RoB in these NRCTs mostly pertained to measurement bias based on self-reporting oral health behaviours. The meta-analysis pooling of results (for RCTs and NRCTs) favoured interventions for CALD parents' oral health knowledge [0.73 (95% CI, 0.08 to 1.38) for RCTs, 1.73 (95% CI; 1.45 to 2.02) for NRCTs] and attitudes [0.86 (95% CI, 0.31 to 1.42)]. Relatively high heterogeneity was observed. Oral health educational interventions can be effective in improving the oral health literacy of CALD parents' oral health knowledge and attitudes, especially when facilitated by lay health advisors. However, the low quality of evidence due to high heterogeneity and high RoB further highlighted the need for well-designed RCTs targeting CALD parents.

Knowledge, Attitudes, and Practices of Occupational Therapists in Promoting Oral Health: A Protocol for Mixed-Methods Systematic Review

BACKGROUND/OBJECTIVES

Poor oral health is a significant global public health concern that adversely affects an individuals' overall health and general well-being. Occupational therapists are well-suited to promote oral health by supporting activities of daily living (ADLs), thereby improving clients' oral health outcomes. However, there is limited evidence on the knowledge, attitudes, and practices (KAPs) of occupational therapists regarding oral health, as well as the barriers and facilitators they face in delivering oral healthcare.

METHODS

This paper outlines a protocol for a mixed-methods systematic review aimed at synthesizing the current evidence on the KAPs of occupational therapists related to oral health, as well as the barriers and facilitators they encounter in promoting it. The upcoming systematic review will follow the Joanna Briggs Institute (JBI) methodology for mixed-methods systematic reviews using a convergent integrated approach to synthesis and integration. The review will include quantitative, qualitative, and mixed-methods studies that report on KAP, barriers, and facilitators associated with occupational therapists' involvement in oral healthcare. A comprehensive search will be conducted across multiple databases, including MEDLINE (Ovid), CINAHL (EBSCO), SCOPUS, EMBASE (Ovid), and OTseeker to identify relevant studies. Two reviewers will independently screen the studies for eligibility, assess their methodological quality, and extract key data for synthesis. The protocol adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines and is registered with PROSPERO (CRD42024522136).

RESULTS

The findings from the planned systematic review are expected to provide valuable insights into the role of occupational therapists in promoting oral health, addressing barriers and facilitators, and shaping policies, training programs, and clinical practices.

CONCLUSIONS

Ultimately, these findings aim to enhance the integration of oral health into occupational therapy and improve client outcomes.

Optimizing mHealth Interventions for Children's Oral Hygiene: A Factorial Trial

Behavioral interventions can improve children's oral hygiene practices. The multiphase optimization strategy (MOST) offers a framework to prepare, optimize, and evaluate behavioral interventions. This optimization trial tested 3 intervention components-brief motivational interviewing (MI), storytelling videos (STVs), and oral health promotion messages (OHPMs)-in enhancing mother's self-reported brushing of their preschool children's teeth. A total of 128 mothers with children <5 y old were included in a 23 factorial trial. The primary outcome was children's plaque accumulation, assessed using the modified Plaque Index of Silness and Löe, with scores ranging from 0 to 3. The secondary outcome was mothers' self-reported frequency of brushing their children's teeth, categorized as at least once daily or less than once daily. Mothers were randomized to 8 experimental conditions based on combinations of on-off levels of the 3 components. Linear regression and generalized linear regression with logit link function were used to assess the impact of the components and their interactions on plaque score and daily toothbrushing after 3 mo. Multiple imputation was used for missing values. The principle of effect hierarchy guided the selection of components for inclusion in the optimized package, giving priority to main effects and 2-way over 3-way interactions. Plaque was reduced from mean = 1.8 at baseline to mean = 1.5 and daily toothbrushing increased from 50.8% to 69.5% after 3 mo. MI led to non-significantly less plaque and non-significantly more daily toothbrushing. Combining OHPMs and STVs together without MI canceled each other. Neither the main effects nor the 2- or 3-way interactions significantly affected the 2 outcomes. Individual or combined components did not significantly reduce plaque or increase daily toothbrushing. MI had the greatest promise for behavior change, and the m-oral health components need modification before they can be combined with MI in a health promotion package.

Evaluation of oral health services and challenges faced by oral health practitioners working in Nyarugenge, Rwanda

OBJECTIVE

Oral healthcare professionals encounter considerable challenges while providing services to curb the oral disease burden. The aim of this study was to explore the challenges faced by oral health practitioners providing oral health services in Nyarugenge, Rwanda and to appraise the availability and adequacy of oral hygiene equipment, instruments, and materials.

METHODS

This was a cross-sectional concurrent mixed methods study. The quantitative and qualitative parts were independent during data collection and analyses and merged during the interpretation phase. All seven public health facilities and 14 dental professionals working in Nyarugenge were included in the study. Data were collected using an audit checklist and an in-depth interview guide. Descriptive statistics were used to analyze the quantitative data. The interviews were analyzed using thematic content analysis.

RESULTS

Most of the dental health professionals were dental therapists (n = 11), women (n = 9), aged 31-40 years (n = 7), and with 11-20 years' experience as oral health practitioners (n = 6). There were five health centers and two hospitals that were audited for equipment, instruments, and materials. The audit of the facilities revealed that most facilities have dental equipment and instruments, but none have adequate preventive dental instruments and materials. Four broad themes emerged from the interviews with the oral health practitioners, namely human resources, supply chain management, patients' oral health awareness and service rendering, and strategic management and administration. The most significant challenges oral health practitioners faced included high dental practitioner/patient ratios, lack of adequate and appropriate equipment and materials, patients' lack of oral health awareness, and a lack of administrative support.

CONCLUSIONS

Well-established community preventive interventions, such as a mobile oral health App, could reduce the patient/provider ratio by increasing population awareness of oral health and encouraging healthy behaviours. The management of the health facilities should address the human resource challenges and equipment supply chain issues.

The role of community health workers in promoting oral health at school settings: A scoping review

OBJECTIVES

The scoping review aimed to examine the literature on the role of Community Health Workers (CHW) in oral health interventions within school settings. The objectives were to identify the characteristics of school oral health interventions where CHWs played a role; and to assess the outcomes derived from CHW participation in school oral health.

METHODS

The scoping review was guided by the Levac et al (2010) framework. Articles selected for this review included all forms of study designs and gray literature. The search strategy included CHW and other non-dental personnel providing oral health activities within schools and the outcomes of these interventions from 1995. Databases included Pubmed, ProQuest, Scopus and EBSCO Host.

RESULTS

There were eleven (n = 11) peer reviewed articles included. Only one study in this review related to CHW involvement in school oral health settings. The remaining involved teachers (n = 4), peer learners (n = 3) or a combination of both (n = 3). Characteristics of the interventions ranged from oral health screenings, education, supervised brushing, and community engagements. Three outcomes emerged; widening access to oral health services, acceptability of non-oral health personnel and learners in promoting oral health and improvement of oral health self-care.

CONCLUSIONS

The review brought to light the benefits of utilizing non-dental personnel such as teachers and peer learners in augmenting staff capacity for school oral health interventions. In addition, the findings highlighted the need to further research on the feasibility and acceptability of integrating CHW in school oral health settings.

Cost-effectiveness of dental caries prevention strategies in South African schools

BACKGROUND

In South Africa, an estimated 85% of the population relies on the public sector for oral health services. With poor infrastructure and inadequate personnel, over 80% of children with dental caries remain untreated. To reduce this burden of disease, one key goal is to promote good oral health and address oral diseases through prevention, screening, and treatment among children. While all policies have been proven to be effective in the control and prevention of dental caries, it is unclear which of those strategies provide value for money. This study evaluated five caries preventative strategies in terms of the cost and benefits among South African school children.

METHODS

The study uses a hypothetical South African population of school aged learners aged 5-15. The context and insights of the strategies utilized at the schools were informed by data from both grey and published literature. Using Markov modeling techniques, we conducted a cost-effectiveness analysis of Acidulated Phosphate Fluoride (APF) application, atraumatic restorative treatment (ART), sugar-reduction and fissure sealants. Markov model was used to depict the movement of a hypothetical patient cohort between different health states over time. We assessed both health outcomes and costs of various interventions. The health outcome metric was measured as the number of Decayed, Missing, Filled Tooth (DMFT). The net monetary benefit was then used to determine which intervention was most cost-effective.

RESULTS

The results showed that school-based caries prevention strategies are cost-effective compared to the status quo of doing nothing. The average cost per learner over the 10-year period ranged from ZAR4380 to approx. ZAR7300 for the interventions considered. The total costs (including screening) associated with the interventions and health outcome (DMFT averted) were: sugar reduction (ZAR91,380, DFMT: 63,762), APF-Gel (ZAR54 million, DMFT: 42,010), tooth brushing (ZAR72.8 million, DMFT: 74,018), fissure sealant (ZAR44.63 million, DMFT: 100,024), and ART (ZAR45 million, DMFT: 144,035). The net monetary benefits achieved for APF-Gel, sugar reduction, tooth brushing, fissure sealant and ART programs were ZAR1.56, ZAR2.45, ZAR2.78, ZAR3.81, and ZAR5.55 billion, respectively.

CONCLUSION

Based on the net monetary benefit, ART, fissure sealant and sugar-reduction appear to be the most cost-effective strategies for preventing caries in South Africa. In a resource-scarce setting such as South Africa, where there is no fluoridation of drinking water, this analysis can inform decisions about service packages for oral health.

Factors predicting oral health behaviors among students age 13-15 years in Shushtar city, Iran

BACKGROUND

Tooth decay and other oral health (periodontal) diseases are highly prevalent worldwide and present a significant economic burden. Oral health is particularly important for adolescents, as the World Health Organization has identified tooth decay as one of the most pressing global health issues. This study aims to identify predictors of oral health behaviors among students aged 13-15 years in the city of Shushtar, Iran.

METHODS

The present research is a cross-sectional study that was conducted during the summer of 2022 on 415 adolescents from the first secondary school in Shushtar. Two standard questionnaires were used to collect data, consisting of demographic information and questions related to measuring awareness, attitude, performance, and self-efficacy regarding oral health behaviors among adolescents. The collected data was analyzed using SPSS 22 statistical software through descriptive statistics, Pearson correlation, and regression analysis.

RESULTS

The average scores for awareness, attitude, self-efficacy in brushing teeth, self-efficacy in flossing, self-efficacy in going to the dentist, and adolescents' performance on oral health behaviors are 5.72 ± 2.06, 36.40 ± 6.36, 25.40 ± 7.49, 14.15 ± 6.06, 15.80 ± 5.59, and 14.01 ± 4.02, respectively.

CONCLUSION

Based on the results of this study, it can be concluded that adolescents have low levels of awareness, performance, self-efficacy, and a positive attitude towards oral health. Considering the significance of adolescence as a stage for shaping oral health behaviors and their impact on adulthood, it is recommended to increase awareness among adolescents and improve their health behaviors by conducting educational classes in schools.

A randomized double-blind clinical trial evaluating comparative plaque and gingival health associated with commercially available stannous fluoride-containing dentifrices as compared to a sodium fluoride control dentifrice

BACKGROUND

Gingivitis is a non-specific inflammatory lesion in response to the accumulation of oral biofilm and is a necessary precursor to periodontitis. Enhanced oral hygiene practices, including utilization of a dentifrice that could significantly improve plaque accumulation and gingival inflammation, is desirable to prevent and treat gingivitis and potentially prevent progression to periodontitis. This clinical study aimed to investigate the effect of a new stannous fluoride-containing dentifrice with 2.6% ethylenediamine tetra acetic acid (EDTA) as an anti-tartar agent to reduce plaque index and gingival index over a 3-month study period compared to other commercially-available fluoride-containing dentifrices.

METHODS

This double-blind, randomized controlled clinical study evaluated plaque, gingival inflammation, and sulcular bleeding in patients using one of five commercially available fluoride-containing dentifrices The dentifrices tested contained: 0.454% stannous fluoride and 2.6% EDTA (D1), 0.24% sodium fluoride (C), and 0.454% stannous fluoride (D2-D4). One hundred fifty subjects participated over a 3-month period. Co-primary endpoints were improvements in plaque index (PI) and modified gingival index (mGI) from baseline values. No professional cleaning was performed during the study period.

RESULTS

All subjects in the study demonstrated statistically significant improvements in all measures of oral hygiene over the 3-month study period. Subjects using dentifrice 1 (D1) showed statistically significantly greater reductions in PI, mGI, and modified sulcular bleeding index (mSBI) compared with all other commercially-available dentifrices tested (p < 0.00001).

CONCLUSIONS

A new dentifrice with 0.454% stannous fluoride and 2.6% EDTA demonstrated significant improvements in clinical parameters associated with gingivitis compared to other sodium and stannous fluoride containing dentifrices.

Better living through chemistry? A randomized, double-blind controlled study evaluating the efficacy of plaque control and gingival health impacts of a novel stannous fluoride-containing gel

BACKGROUND

Gingivitis is a nonspecific inflammatory lesion in response to the accumulation of oral biofilm and is a necessary precursor to periodontitis. Enhanced oral hygiene practices are necessary to reverse gingivitis and a dentifrice that could provide significant clinical reductions in plaque accumulation and gingival inflammation would be desirable to treat gingivitis and potentially prevent progression to periodontitis. This clinical study aimed to investigate the effect of a novel stannous fluoride-containing dentifrice with 2.6% ethylenediamine tetra-acetic acid (EDTA) as an antitartar agent to reduce Plaque Index (PI) and Gingival Index over a 3-month study period.

METHODS

This double-blind, randomized controlled clinical study evaluated plaque, gingival inflammation, and sulcular bleeding in patients using either a novel dental gel containing 0.454% stannous fluoride and 2.6% EDTA or a dentifrice with 0.24% sodium fluoride. Sixty subjects participated over a 3-month period. Co-primary endpoints were improvements in PI and Modified Gingival Index (mGI) from baseline values. No professional cleaning was performed during the study period.

RESULTS

All subjects in the study demonstrated statistically significant improvements in all measures of oral hygiene over the 3-month study period. Subjects using the novel dental gel showed statistically significantly greater reductions in PI (ΔPI) [(-1.43 ± 0.34; -0.49 ± 0.13) (p < 0.00001)], mGI (ΔmGI) [(-1.11 ± 0.22; -0.16 ± 0.12) (p < 0.00001)], and modified sulcular bleeding index (ΔmSBI) [(-1.15 ± 0.18; -0.20 ± 0.07) (p < 0.00001)].

CONCLUSIONS

The novel dental gel demonstrated significant improvements in clinical parameters associated with gingivitis compared to a commercially available sodium fluoride dentifrice.
