Effectiveness of the school-based oral health promotion programmes from preschool to high school: A systematic review

Knowledge, attitudes, and behaviours of Irish preschool teachers regarding the oral health of preschool children

AIM

To assess the knowledge, attitudes, and behaviours of Irish preschool teachers regarding the oral health (OH) of preschoolers aged 3-5 years old.

METHODS

A validated 15-item questionnaire was completed by 90 preschool teachers in Dublin in January 2024. The questionnaire collected information on general demographics and assessed the knowledge and attitudes of teachers regarding early childhood OH. In addition, guided interviews were conducted to find out preschool teachers' awareness of OH training and resources, the challenges they face in organising OH education and their suggestions for improvement.

RESULTS

Out of a cohort of 90 respondents, the mean number of questions answered correctly was 5.32 out of 9. One-third (34.4%) of the teachers said they learnt their OH knowledge from school or college, 8.9% from early childhood care training, 22.2% from their own dentist and 24.4% from other sources. Most teachers implemented OH education in some form whilst others said they had no time or resources. Qualitative data revealed a lack of formal OH training and knowledge, ideas for integrated OH activities, importance of collaboration and community engagement, barriers and challenges in implementation and need for mandatory OH training.

CONCLUSION

There are gaps in OH knowledge and lack of OH training for Irish preschool teachers. By identifying barriers and facilitators around OH training and resources for preschool teachers, the preschool teachers can be encouraged to create more supportive environments for improved OH.

Effectiveness of a School-Based Oral Health Promotion Program on Dental Caries Among Iraqi School Children: A Cluster Randomised Controlled Trial

AIM

To assess the effectiveness of a school-based oral health promotion program on dental caries of permanent dentition among Iraqi children.

METHODS

A cluster randomised controlled trial was conducted with a parallel study group, comprising 8-10-year-old schoolchildren, 186 in each group. At the beginning of the study, subjects in the intervention group received oral health education and a single dose of 5% sodium fluoride varnish for all teeth surfaces while the control group only received oral health education. The primary outcome data in this study were caries increment and incidence after six months. The secondary outcome data was any change in oral health behaviors in the students of both groups after 3 months. The caries status was recorded according to International Caries Detection and Assessment System (ICDAS). Statistical analyses included the Chi-square test, McNemar test, independent t-test, simple and multiple logistic regression models.

RESULTS

Study participants included 372 children with no significant difference in baseline characteristics between intervention and control groups. An increase was evident in the mean scores of DMFS, DMFT, number of children with DMFT > 0, and DS > 0 for both control and intervention groups at six-month follow-up but this increase was significantly higher for the control than intervention group (P < .001). Among all variables included in the multiple logistic regression model, just being in the intervention group showed a significant effect in which children in the control group had a 4.2-fold (95% CI: 2.36-7.54) greater chance for developing new caries than children in the intervention group. There was a statistically significant increase in the percentage of children with favourable levels of behaviors between baseline and 3-month follow-up (P < .05, P < .001).

CONCLUSION

Providing access to oral health services such as oral examination, fluoride varnish application, and oral health education to reduce dental caries and improve oral health practices seems to be effective among primary schoolchildren.

Oral Health Promotion in Pediatric Age Groups: Habits and Behaviors of Italian and Spanish Parents and Children

Objectives: The aim of this study was to evaluate the level of knowledge and awareness among parents regarding oral hygiene habits in two different national groups and to raise awareness among parents about oral hygiene education. Methods: A sample of 640 parents from Rome (Italy) and Valencia (Spain) was collected. The survey involved children between 0 and 18 years of age. An online questionnaire was administered to gather information regarding demographic data, the level of knowledge about dental caries and its transmission, proper oral hygiene habits of parents with regard to their children, mothers' attitudes towards their own oral health before or during pregnancy, awareness of risk behaviors, such as the use of pacifiers or baby bottles, sharing cutlery, the use of the same toothbrush in the entire family, the role of schools, and oral health prevention techniques. Results: The comparison between the two groups shows that Spanish parents are more attentive to oral hygiene measures compared to Italian parents, especially about the knowledge of dental caries and its transmission, oral health check-ups during pregnancy, and proper oral hygiene habits. In both groups, there is still little knowledge about oral prevention methods. Conclusions: From the results of our survey, we can conclude that the knowledge regarding oral hygiene among parents from both countries is not yet optimal when compared to international health objectives. It is necessary to promote oral health prevention programs both in schools and within families in order to improve children's oral health.

Special education teachers' involvement and perceived barriers to delivering oral health education for students with disabilities-A cross-sectional study

BACKGROUND

Dental caries is prevalent among children, including those with disabilities. Although the World Health Organization recommends school-based oral health promotion (OHP) programmes involving teachers, limited research has explored teachers' roles and perspectives.

AIM

To assess special education teachers' involvement and difficulties regarding oral health education (OHE), attitudes towards OHP and barriers to oral healthcare access for students with disabilities (SWDs).

DESIGN

This descriptive cross-sectional study, conducted in Al-Ahsa, Saudi Arabia, involved 264 special education teachers using a validated, self-administered questionnaire, and descriptive and analytical statistics were used for data analysis.

RESULTS

Only 39% of teachers incorporated OHE into their teaching, and just 20.8% received training for OHE delivery. Teachers showed strong support for integrating OHE into the curriculum (84.1%) and a no-sugar policy (78%). There was, however, less support for school-based toothbrushing (39%). OHE barriers included insufficient resources (56.1%), limited knowledge (29.2%) and misconceptions about primary teeth removal (47.4%). The three most common barriers to oral healthcare access were extended waiting lists (75.0%), long waiting times (73.1%) and fear of dental equipment (67.4%).

CONCLUSION

This study highlights the need for collaboration between healthcare professionals, educators and parents to enhance OHE and reinforce OHP for SWDs within special education and beyond.

Dietary and Hygiene-Related Knowledge Versus Reported Behaviors of Eighteen-Year-Olds: A Nationwide Cross-Sectional Study

Background/Objectives: The aim of the present study was to examine eighteen-year-olds' self-assessed knowledge about diet and hygiene, behaviors that they report, and education they receive during dental appointments. Methods: Questionnaires distributed among 1611 subjects included questions concerning sociodemographic factors, dietary and hygiene knowledge and behaviors, and dental visits. Spearman's rank correlation and a bivariate and multivariate logistic regression analysis was conducted; odds ratios (ORs) and adjusted odds ratios (AORs) were calculated (p ≤ 0.05). Results: Respondents self-assessed their oral health knowledge; 63.1% of them considered it to be limited, and 40.7% understood the cariogenic effect of frequent snacking. Dentists and a dental team (DT) were the main source of information (55.7%). Dietary advice was recommended by 10.8% of dentists and the DT, while check-up appointments were advised by 49.2%. Parents' higher education contributed to a lower intake of cariogenic food. This effect was stronger for the mother's education. Dental appointments scheduled twice a year increased the chances of consuming healthy food (A2OR = 1.21 (1.07-2.11); p = 0.0028). Being informed increased the chances of toothbrushing ≥ 2 times (OR: 1.21, CI 1.10-1.46), using fluoridated toothpaste (OR: 1.26 CI1.05-1.55), and the frequency of appointments (A1OR: 1.56 CI 1.21-1.87; A2OR: 1.78 CI 1.54-1.91). Conclusions: Knowledge and oral health related behaviors, as well as the involvement of the dental team in education, are inadequate. Education and instruction in the dental office has a favorable influence on oral-health-related behaviors. It is, therefore, necessary to undertake systemic solutions so that dental practitioners are more involved. Providing oral health knowledge should be the standard of care.

A scoping review on early childhood caries and inequalities using the Sustainable Development Goal 10 framework

BACKGROUND

Social inequalities contribute to health disparities. This study aimed to map evidence on early childhood caries (ECC) related to the United Nations' Sustainable Development Goal 10 (SDG 10).

METHODS

A scoping review was conducted in May 2024 following the PRISMA-ScR guidelines. A literature search was performed in PubMed, Web of Science, and CINAHL for studies published in English and addressing population level social inequalities. Studies measuring individual level of social inequalities were excluded as they were covered by other SDGs. However, studies incorporating individual measures as additional measures of population level social inequality were included. Retrieved papers were summarized, inductively analysed and a conceptual framework linking SDG 10 was developed.

RESULTS

Of 452 studies retrieved, 42 met the inclusion criteria. Studies measured inequality among groups (deprivation, family income, indigenous communities, ethnicity, minority status) [14 studies], institutions (type of school, nursery or school facility, school poverty index, public primary health care units) [five studies], and inequality in communities (neighbourhood socio-economic status, Human Development Index, employment rate, income inequality, sanitary sewer and water supply, residents/household ratio, urban vs rural vs remote rural, accessibility index, location index, the slope index of inequality) [24 studies]. These levels of social inequalities were linked to higher prevalence of ECC; social and economic policies contributed to widening inequalities in ECC severity; and although effective interventions targeted at at-risk populations could reduce dental health disparities, study interventions differed by deprivation status. Six studies (14.3%) addressed SDG 10.1, 33 (78.6%) addressed SDG 10.2, 11 (26.2%) addressed SDG 10.3, and three (7.1%) addressed SDG 10.4. Fourteen studies (33.3%) addressed a combination of SDGs. The conceptual framework highlights the role of structural inequalities stemming from the cumulative impact of institutional decisions and systemic inequalities.

CONCLUSION

This scoping review underscores the profound influence of social inequality on ECC through interactions between multi-level factors. Further research is needed to explore the links between ECC and other SDG 10 targets, especially in low- and lower-middle-income countries.

Evaluation of Broccoli Extract for Enhancing Primary Tooth Enamel Microhardness: An In Vitro Study

Background and Aims

Dental caries remains highly prevalent among children. This study aimed to evaluate the efficacy of aqueous broccoli extract in enhancing the microhardness of demineralized primary tooth enamel compared to a standard fluoride treatment.

Methods

An in vitro study was conducted using 30 extracted primary second molars, which were sectioned and polished. Baseline enamel microhardness was assessed using a Vickers hardness tester. Demineralization was induced using a cola drink (pH 4.5) for 8 min. The broccoli extract was prepared by air-drying fresh florets, stems, and leaves at room temperature, followed by aqueous extraction with distilled water and filtration. The samples were randomly assigned to receive a 10-min treatment with either aqueous broccoli extract (Group B) or 1.23% acidulated phosphate fluoride (APF) gel (Group F). Microhardness was measured posttreatment, and percentage changes between time points were compared using statistical analysis.

Results

After demineralization, broccoli extract, and fluoride gel significantly improved enamel microhardness. The broccoli extract group exhibited a greater recovery in microhardness (+44.95% vs. +20.78%, p = 0.008) compared to the fluoride gel group. However, the overall reduction in microhardness from baseline to final measurement showed no statistically significant difference between the two groups (p = 0.077).

Conclusion

Aqueous broccoli extract demonstrated comparable overall efficacy to fluoride gel in enhancing demineralized primary tooth enamel microhardness despite showing different patterns of demineralization and recovery. These findings suggest that broccoli extract may be a natural and effective alternative for enhancing enamel remineralization in pediatric caries prevention, warranting further clinical investigation.

Effectiveness of school-based oral health education interventions on oral health status and oral hygiene behaviors among schoolchildren: an umbrella review

OBJECTIVE

To summarize evidence of the effectiveness of school-based oral health education interventions on oral health status and oral hygiene behaviors among schoolchildren.

METHODS

A comprehensive search was conducted across seven databases MEDLINE Ovid, Google Scholar, Web of Science, Scopus, EBSCO-APA PsycInfo, ProQuest, and CINAHL, with two independent reviewers screening titles and abstracts including full texts. Data extraction procedure and quality appraisal of this umbrella review adhered to the JBI critical appraisal checklist. Systematic reviews of RCTs in which schoolchildren of 5 to 18 years of age received oral health education in a classroom-based school setting from dentists, schoolteachers, or caregivers were included. Key outcome measures included distinct oral health indices, as well as knowledge, attitudes, and practices.

RESULTS

A total of 27 relevant systematic reviews were included for the umbrella review. Methodological quality was substantial among most systematic reviews, thus enhancing the strength of reliability of findings. Nineteen were graded excellent (scores 30 to 33), four were classified as good quality (scores 26 to 29), four rated as fair quality (scores 21 to 25) and none rated as poor-quality (scores 20 or below). Numerous studies from various nations were identified, with reviews peaking in 2019 and 2021. The overlap assessment reveals slight degree of overlap (3.73% overlap, -0.45% CCA-corrected covered area). Meta-analyses show that oral health education interventions had a favorable impact on a number of outcomes, such as reduced plaque and gingivitis, enhanced knowledge, attitude, and behavior, and improved oral cleanliness.

CONCLUSION(S)

This umbrella review provides a comprehensive synthesis of the effectiveness of oral health education interventions in school settings. Positive outcomes in plaque reduction and gingivitis prevention affirm the benefits of these programs, though the evidence for caries prevention remains inconclusive. The findings highlight the broader impact of these interventions on students' knowledge, attitudes, and behaviors, emphasizing the need for tailored approaches and further research to optimize oral health education. This review serves as a valuable resource for educators, healthcare professionals, and policymakers dedicated to improving pediatric oral health.

Parental perceptions of an oral health promotion program in early childhood education and care settings: A qualitative study

OBJECTIVES

Early Childhood Caries is a global health problem. The Bright Smiles Bright Futures (BSBF) program seeks to equip educators, children, and parents with skills and knowledge about oral health promotion habits early in life. The aim of this study was to examine parental perceptions of the BSBF program and identify key facilitators and barriers for its implementation.

METHODS

Twelve mothers of children who participated in the BSBF program in five Early Childhood Education and Care (ECEC) settings in NSW, Australia were recruited in this qualitative study. Data were collected via focus groups and interviews, transcribed verbatim and coded to categorize for inductive thematic analysis.

RESULTS

Five major themes emerged: Promoters of the BSBF oral health program, barriers to the BSBF oral health program implementation and participation, online resources, impact of the BSBF oral health program, and strategies for enhancing the BSBF oral health program. While participants reported that the program encouraged their children's toothbrushing, they found issues with the program's materials, ECEC center attendance, and communication about the oral health program with their children. The program improved message retention, attitudes, routines, and family perceptions toward oral health. Participants recommended oral health literacy, changed delivery formats, increased dental access, and inclusion of interactive elements to enhance the program.

CONCLUSIONS

The findings from this study provide insight to improve parents' experiences and engagement in oral health promotion. This can help to raise awareness of the importance of child oral health among policymakers, healthcare professionals, and the public to inform public health policy discussions.

Effectiveness of school oral health programs in children and adolescents: an umbrella review

AIM

To evaluate the systematic reviews assessing the effectiveness of any type of school-based oral health programs in children and adolescents.

METHODOLOGY

A two-staged search strategy comprising electronic databases and registries based on systematic reviews was employed to evaluate the effectiveness of school-based interventions. The quality assessment of the systematic reviews was carried out using the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) tool. The Corrected Covered Area was used to evaluate the degree of overlap.

RESULTS

Nine reviews were included in this umbrella review. The Critical Covered Area reported moderate overlap (5.70%) among the primary studies. The assessment of risk of bias revealed one study with a high level confidence; one with moderate whereas all other studies with critically low confidence. Inconclusive evidence related to improvements in dental caries and gingival status was reported whereas, plaque status improved in a major proportion of the reviews. Knowledge, attitude, and behavior significantly increased in students receiving educational interventions when compared to those receiving usual care.

CONCLUSIONS

The evidence points to the positive impact of these interventions in behavioral changes and clinical outcomes only on a short term basis. There is a need for long-term follow-up studies to substantiate the outcomes of these interventions.

Toothbrushing programme in Saudi Arabia 'TOPS': a study protocol for a cluster randomised controlled trial in kindergartens, Riyadh

INTRODUCTION

Dental caries among children is a major global health problem and is a particular public health challenge in Saudi Arabia. Dental caries cause pain, infection and negatively impact quality of life. As part of population oral health improvement efforts in Saudi Arabia, this project aims to evaluate the effectiveness of a supervised toothbrushing programme in kindergartens.

METHODS AND ANALYSIS

This study is a cluster randomised controlled trial. Enrolment began in September 2022, for two academic years (2022-2024) on 20 randomly selected kindergartens in Riyadh. The data collection phase will be completed in September 2024. Ten kindergartens are randomly allocated to supervised toothbrushing and 10 to treatment as usual, which is an annual oral health awareness visit. The primary endpoint will be the worsening of obvious decay experience as measured by decayed (into dentine), missing and filled teeth (d3mft) from baseline to the second year of follow-up. The secondary endpoint will be the increase in the number of teeth affected. A priori subgroups of the region of Riyadh, school type (public, private), child sex and presence/absence of prior decay at baseline, will be analysed. We require 244 evaluable endpoints using a power of 80% to meet the sample size requirement. In addition, questionnaires on behaviours, quality of life, process monitoring and cost analysis are being deployed.

ETHICS AND DISSEMINATION

Ethics approval for this study was given by the King Fahad Medical City Institutional Review Board in the Saudi Ministry of Health (22-083E/March 2022). The data analysis has been approved by the University of Glasgow Medical Veterinary and Life Sciences Research Ethical Committee (200220194/March 2023). The results of this study will be disseminated through presentations at scientific conferences and in scientific journals.

A Qualitative Study of Preschool Children's Perspectives on an Oral Health Promotion Program in New South Wales, Australia

In Australia, dental caries are observed in almost half of children starting school. Oral health promotion programs are being implemented in early childhood education and care (ECEC) settings to promote oral health. This study examined children's perceptions of one such program, the Bright Smiles Bright Futures (BSBF) program in ECEC settings in New South Wales, Australia. Data were collected using focus group discussions from 15 children aged 3-5 years, transcribed verbatim, and analysed through inductive thematic analysis. Three themes were identified as follows: (i) oral health knowledge of children, (ii) oral hygiene practices routine and skills development, and (iii) evaluation of the oral health promotion kit and opportunities for improvement. Children's perspectives highlight the BSBF program's success in communicating key messages to promote oral health. The integration of family-centric approaches, acknowledgement of children's preferences, and the use of interactive tools collectively enhance the overall effectiveness of the oral health promotion program.

Charting the Future of Oral Health: A Bibliometric Exploration of Quality-of-Life Research in Dentistry

In recent decades, the focus of health research has shifted to the impact of disease or impairment on how people proceed, behave, and experience quality of life. People's lives are affected by oral diseases in various ways. Oral health-related quality of life (OHRQoL) is inextricably linked to general health and well-being, and it has far-reaching consequences for clinical practice and dentistry research. Particularly in Indonesia, increasing attention to OHRQoL is related to several concerning oral conditions, such as the extremely high number of cases of tooth decay and inflammation of dental supportive tissue that inexplicably lowers the population's OHRQoL. To date, there has yet to be a bibliometric study of OHRQoL research in Indonesia. We intend to map the existing scientific literature on OHRQoL research in Indonesia during the last five years and investigate its research gaps. Scopus and the Sinta Database (a national database through Google Scholar) were used to retrieve Indonesian OHRQoL research publications from 2018 to 2023. Bibliographic data were analyzed using SPSS Statistics 25.0 and VOS Viewer 1.6.19. The data demonstrate that the number of OHRQoL-related publications in Indonesia and the number of local writers have increased over time. More of these publications were published in prestigious national journals than foreign ones. The study found that local researchers tended to conduct OHRQoL research on children and older populations, raising the issue of tooth decay or tooth loss. Exploring other subjects, such as dental anxiety, patient satisfaction, chewing performance, aesthetics, and appearance, and other populations (people with oral cancer and other systemic conditions) could broaden the environment of OHRQoL research in Indonesia.

Effectiveness of theory-based educational interventions of promoting oral health among elementary school students

BACKGROUND

The aim of the present study was to determine the effect of oral health education programs on the oral health of primary school students.

METHODS

In this randomized controlled trial study, 190 elementary fifth-grade female students were chosen using the multistage cluster sampling method. In this study, the Plaque Index (PI), Simplified Oral Hygiene Index (OHI-S), Community Periodontal Index (CPI), tooth brushing using fluoride toothpaste, dental flossing frequency and factors affecting them were determined according to social cognitive theory (SCT). Interventions were implemented using the play method and with the help of three pamphlets, five posters, a celebration of oral health, and the creation of a Telegram group. Data were analyzed using descriptive statistics indexes, t tests, paired sample t tests, chi-square tests, and Pearson correlation tests.

RESULTS

The results showed that 3 months after the intervention, compared to before the intervention, the percentage of participants in the intervention group who brushed their teeth twice or more per day increased by 48.5%, and the percentage of participants who used dental floss at least once per day increased by 64.2%. The rate of gum bleeding decreased by 6.3%. The good OHI-S rate increased by 44.4%. Dental plaque decreased by 38.1%.

CONCLUSION

The results demonstrated that a gamification design can be effective and useful in promoting the oral health of students.

The gamification and development of a chatbot to promote oral self-care by adopting behavior change wheel for Taiwanese children

Background

Oral health is closely related to general health and quality of life. School-aged children are at a critical stage for developing their self-care ability in oral health. Digital interventions can encourage and facilitate oral self-care in children.

Objective

This study aims to present the development of an educational chatbot for school-aged children to address their oral self-care and evaluate its usability.

Methods

The development and evaluation of the chatbot for oral self-care consisted of four stages: target behavior analysis, intervention design, system development, and the chatbot evaluation. The target behavior analysis identified barriers to children's engagement in oral self-care based on dentists' clinical observations; hence, the requirements for achieving the desired behavior were categorized according to the capability-opportunity-motivation behavior model. Interventional functions were created following the behavior change wheel. A menu-driven chatbot was created and evaluated for usability as well as likeability.

Results

The barriers and requirements for achieving good behavior in school-aged children's oral self-care were identified by the dental professionals. Intervention strategy incorporated specific functions enriched with gamification features to support school-aged children in developing their abilities for engaging in oral self-care. The intervention functions consist of capability establishment, motivation enhancement, and opportunity creation, which were designed to support children in their oral self-care practices. The designed chatbot was piloted with a convenient sample of 30 school-aged children and their accompanying parents at the pediatric dental clinic. The results indicated good usability, with a mean usability score of 79.91, and high likeability with a mean score of 4.32 out of 5 for the designed chatbot.

Conclusions

The educational chatbot incorporated a combination of clinical dentistry practice and guidelines, aiming to promote oral self-care behavior in school-aged children. The designed chatbot achieved high scores for its usability and user likability.

Improvement of parents' oral health knowledge by a school-based oral health promotion for parents of preschool children: a prospective observational study

BACKGROUND

Parents of preschool children have inadequate oral health knowledge in Hong Kong. Parents play a critical role in preschool children's dietary patterns and oral health behaviors. A school-based oral health promotion (OHP) for parents of preschoolers was developed and investigated.

OBJECTIVES

The objective of this study was to evaluate effects of the school-based OHP for parents of preschool children on parents' oral health knowledge and preschool children's early childhood caries (ECC).

MATERIALS AND METHODS

This was a quasi-experimental study. Parents of preschool children were divided into the intervention group (IG) and the control group (CG) according to their own selection. Parents in the IG participated in a structured school-based OHP workshop, while those in the CG did not attend the OHP workshop. Parents in both groups were invited to complete a questionnaire assessing their oral health knowledge before (T0), one month after (T1), and twelve months after (T2) the OHP workshop. Preschool children's caries was examined via dmft score at T0 and T2.

RESULTS

Parents' oral health knowledge was negatively correlated with preschool children's dmft scores (R = -0.200, P < 0.001). Oral health knowledge was significantly improved in IG (P < 0.001) but not in CG (P = 0.392) at T1. Both groups experienced a significant improvement in oral health knowledge from T0 to T2 (P < 0.001). Parents' oral health knowledge in the IG was significantly higher compared to the CG at T1 (P < 0.001), but difference in the scores at T2 between the two groups showed no significant difference (P = 0.727). No significant difference was found in changes in children's dmft score from T0 to T2 between the IG and CG (p = 0.545).

CONCLUSION

Preschool children's high ECC is associated with the limited oral health knowledge of their parents. The school-based OHP workshop for parents increased parents' oral health knowledge within one month. This positive effect was maintained for twelve months and can be extended to a larger scale in the school setting.

Is Parental Rating of Child's Oral Health Associated with Caries Experience in Children? A Cross-Sectional Study

Aim

The Parents' view to the oral health of their children is a significant factor that can impact oral health practices and behaviors. The aim of this research was to investigate how parental assessment of their child's oral health associates with caries experience in children receiving dental treatment at the hospital of Taibah University Dental College.

Materials and Methods

This cross-sectional study enrolled 127 children who underwent dental treatment at Taibah University Dental College and Hospital during 2020-2021. Dental caries experience was assessed using the dmft/DMFT index, and parental rating of oral health was obtained through a questionnaire. Three logistic regression models were used to assess the correlation between dental caries experience and parental rating of oral health while controlling for sociodemographic and behavioral factors.

Results

Most parents rated the oral health of their child as good (60.4%), followed by excellent (18.8%) and very good (15.6%). The mean dmft/DMFT score was 3.47 ± 3.46, with 43.8% of children having high/very high dental caries experience. Logistic regression analysis showed that children whose parents rated their oral health as poor were more likely to have high/very high dental caries experience compared to those rated as excellent/very good/good/fair (adjusted odds ratio = 4.45, 95% confidence interval 1.23-16.07).

Conclusion

This study suggests a link between parental assessment of their child's oral health and an elevated prevalence of dental caries in children. The study found that children whose parents rated their oral health as suboptimal had higher odds of having high dental caries experience. These findings emphasize the significance of parental perception of their child's oral health and suggest a necessity for customized interventions to enhance parental knowledge and practices concerning children's oral health.

Cost components of school-based oral health-promoting programs: A systematic review protocol

INTRODUCTION

Oral health-promoting school programs play a crucial role in achieving universal coverage of oral health care, by addressing oral diseases and promoting the well-being and quality of life of children and adolescents. However, a lack of studies has evaluated the costs associated with implementing these programs, which hinders decision-makers in adopting them on a large scale. This review aims to assess the cost components involved in school-based oral health-promoting programs.

METHODS

This review will include studies that have conducted either partial or full economic evaluations, focusing on describing the cost components of oral health-promoting programs implemented in primary schools involving students aged 6 to 14. A systematic search was conducted across multiple databases: MEDLINE, The Cochrane Library, the Virtual Health Library, the NHS Economic Evaluation Database, Web of Science, Scopus, and EMBASE. Additionally, gray literature was searched using the Health Technology Assessment Database. Two independent reviewers will screen the titles and abstracts, followed by a full-text review based on predefined inclusion criteria. Data extraction and critical appraisal evaluation will also be carried out independently by two reviewers. In case of disagreements, the reviewer team will resolve them through discussion.

DISCUSSION

The systematic review resulting from this protocol aims to provide evidence regarding the cost components and necessary resources for implementing and maintaining oral health-promoting school programs. This information can assist decision-makers in adopting these programs on a larger scale and effectively addressing oral diseases among children and adolescents.

Cost-effectiveness of Dental Workforce Expansion Through the National Health Service Corps and Its Association With Oral Health Outcomes Among US Children

Importance

Despite considerable efforts to improve oral health for all, large disparities remain among US children. A dental professional shortage is thought to be among the determinants associated with oral health disparities, particularly for those residing in underserved communities.

Objective

To evaluate the cost-effectiveness of expanding the dental workforce through the National Health Service Corps (NHSC) and associations with oral health outcomes among US children.

Design, Setting, and Participants

A cost-effectiveness analysis was conducted to estimate changes in total costs and quality-adjusted life years (QALYs) produced by increasing the NHSC funding for dental practitioners by 5% to 30% during a 10-year period. A microsimulation model of oral health outcomes using a decision analytic framework was constructed based on oral health and dental care utilization data of US children from 0 to 19 years old. Data from the nationally representative National Health and Nutrition Examination Survey (NHANES, 2011-2016) were linked to county-level dentist supply and oral health professional shortage areas (HPSAs) information. Changes in prevalence and cumulative incidence of dental caries were also estimated. Sensitivity analyses were conducted to assess the robustness of results to variation in model input parameters. Data analysis was conducted from August 1, 2021, to November 1, 2022.

Exposures

Expanding dental workforce through the NHSC program.

Main Outcomes and Measures

Changes in total QALYs, costs, and dental caries prevalence and cumulative incidence.

Results

This simulation model informed by NHANES data of 10 780 participants (mean [SD] age, 9.6 [0.1] years; 5326 [48.8%] female; 3337 [weighted percentage, 57.9%] non-Hispanic White individuals) found that when funding for the NHSC program increased by 10%, dental caries prevalence and total number of decayed teeth were estimated to decrease by 0.91 (95% CI, 0.82-1.00) percentage points and by 0.70 (95% CI, 0.62-0.79) million cases, respectively. When funding for the NHSC program increased between 5% and 30%, the estimated decreases in number of decayed teeth ranged from 0.35 (95% CI, 0.27-0.44) to 2.11 (95% CI, 2.03-2.20) million cases, total QALY gains ranged from 75.76 (95% CI, 59.44-92.08) to 450.50 (95% CI, 434.30-466.69) thousand QALYs, and total cost savings ranged from $105.53 (95% CI, $70.14-$140.83) to $508.23 (95% CI, $598.91-$669.22) million among children residing in dental HPSAs from a health care perspective. Benefits of the intervention accrued most substantially among Hispanic children and children in low-income households.

Conclusions and Relevance

This cost-effectiveness analysis using a decision analytic model suggests that expanding the dental workforce through the NHSC program would be associated with cost savings and a reduced risk of dental caries among children living in HPSAs.

The impact of dentists' availability in delivering dental care in Florida Elementary Schools

OBJECTIVE

This study evaluates the dentists' availability to deliver preventive dental care to children in schools and the impact of school-based programs on access.

METHODS

The study population included Florida elementary-school children, differentiated by dental insurance (Medicaid, CHIP, private, or none). We considered the implementation of school-based programs using optimization modeling to (re)allocate the dentists' caseload to schools to meet demand for preventive care under resource constraints. We considered multiple settings for school-based program implementation: (i) school prioritization; and (ii) dentists' participation in public insurance. Statistical inference was used to identify communities to improve access and reduce disparities.

RESULTS

School-based programs reduced unmet demand (3%-12%), being more efficient if prioritizing schools in communities targeted to improve access. The access improvement varied by insurance status and geography. Uninsured urban children benefited most from school-based programs, with 15%-75% unmet need reduction. The percentage of urban communities targeted to improve access decreased by 12% against no-school program. Such percentage remained large for suburban (15%-100%) and rural (50%-100%) communities. Disparity in access for public-insured vs. private-insured children persisted under school-based programs (32%-84% identified communities).

CONCLUSION

School-based programs improve dental care access; the improvement was however different by insurance status, with uninsured children benefiting the most. Accounting to the dentists' availability in prioritizing schools resulted in effective resource allocation to school-based programs. Access disparities between public and private-insured children did not improve; school-based programs shifted resources from public-insured to uninsured. School-based programs are effective in addressing access barriers to those children experiencing them most.

Effectiveness of an oral health curriculum in reducing dental caries increment and improving oral hygiene behaviour among schoolchildren of Ernakulam district in Kerala, India: study protocol for a cluster randomised trial

INTRODUCTION

Children's learning abilities suffer when their oral health is compromised. Inadequate oral health can harm children's quality of life, academic performance, and future success and achievements. Oral health problems may result in appetite loss, depression, increased inattentiveness, and distractibility from play and schoolwork, all of which can lower self-esteem and contribute to academic failure. An oral health curriculum, in addition to the standard school curriculum, may instil preventive oral hygiene behaviour in school students, enabling them to retain good oral health for the rest of their lives. Because most children attend school, the school setting is the most effective for promoting behavioural change in children. A 'health-promoting school' actively promotes health by enhancing its ability to serve as a healthy place to live, learn and work, bringing health and education together. Making every school a health-promoting school is one of the joint objectives of the WHO and UNICEF. The primary objective of this proposed study is to assess the effectiveness of an oral health curriculum intervention in reducing dental caries incidence and improving oral hygiene behaviour among high school children in grades 8-10 of the Ernakulam district in Kerala, India. If found to be effective in changing children's behaviour in a positive way, an oral health curriculum may eventually be incorporated into the school health curriculum in the future. Classroom interventions can serve as a cost-effective tool to increase children's oral health awareness.

METHODS AND ANALYSIS

This protocol presents a cluster randomised trial design. It is a parallel-group comparative trial with two arms having a 1:1 distribution-groups A and B with oral health curriculum intervention from a dental professional and a schoolteacher, respectively. High schools (grades 8-10) will be selected as clusters for the trial. The minimum cluster size is 20 students per school. The total sample size is 2000 high school children. Data will be collected at three time points, including baseline, after 1 year (mid-term) and 2 years (final), respectively. The outcome measures are Decayed, Missing and Filled Teeth Index; Oral Hygiene Index-Simplified; and knowledge, attitude and behaviour. Data collection will be done by clinical oral examination and questionnaire involving oral health-related knowledge, attitude and behaviour items.

Do Right, Be Bright: A Protocol on the Development of an Inter-Professional Health Intervention Model for Pre-School Children Through a Community-Based Service-Learning Initiative

An inter-professional project with a collaborative endeavor between the programs of Dentistry, Nutrition and Medicine was carried out with the aim to emphasise oral health maintenance, making the right nutritional choices and effective hand washing among pre-school children. The purpose of this paper is to share a detailed description of the design, development process, implementation, and planned evaluation of an interprofessional school-based health promotion intervention model "Do Right, Be Bright". This model is part of a quasi-experimental study, targeting pre-school children as the "Targets of Change" through the empowerment of school teachers as the "Agents of Change". The program design was based on Bartholomew's Intervention Mapping Approach, which proposes a direction for developing a theory-based health promotion intervention and on the most extensively applied theories of health behavior, the Health Belief Model. Therefore, based on a thorough literature review and needs assessment, three key areas of needs were identified for the targeted preschool children: oral hygiene, hand hygiene and nutrition. The efficacy of this model will be pilot tested in a preschool in Kuala Lumpur Malaysia.

Effectiveness of an integrated model of oral health-promoting schools in improving children's knowledge and the KAP of their parents, Iran

INTRODUCTION

The aim of our study was to investigate the effect of an Oral Health Promoting School (OHPS) model on children's oral health in Iran.

METHODS

This interventional quasi-experimental study was conducted in the academic year 2019-20 among 354 primary school students and their parents. A questionnaire including 17 questions was distributed among children before and 5 months after the program (The ranges of possible scores = 0-17). Training workshops for the parents based on the theoretical domains framework were designed. Using educational sessions, pamphlets, tooth brushing dairies, assignments to do at home, educational videos and messages as reminders in social networks, parents were educated about dental caries, its risk factors and prevention principles. Best recommended oral health behaviors including tooth brushing and the use of fluoridated tooth paste were also educated. A questionnaire consisting of 18 knowledge (The ranges of possible scores = 0-18), 13 attitude and 10 practice questions were distributed among parents before and after the workshops. The data were fed into SPSS and analyzed by descriptive and analytic statistics such as T-test, ANOVA and Correlation Coefficients (α = 0.05).

RESULTS

The mean pre-test knowledge (7.8 ± 1.7) was increased significantly in three schools after program, p < 0.001. In the post-test, girls gained significantly higher scores (9.61 ± 1.98 vs. 9.06 ± 1.4, p = 0.025). Among 147 parents, the mean knowledge was raised from 12.3 ± 3.1 (5-18) to 15 ± 3.03 (6-18), p < 0.001. Knowledge score of the parents attending both sessions was higher. Practice of the parents regarding the use of fluoridated tooth-paste was significantly improved (p < 0.001). Also, their attitude toward the ability of children to take care of their teeth was improved (p = 0.029). Based on the self-report of parents, 71.4% (n = 47) of mothers and 45.6% (n = 67) of their children used to brush once or two times daily and there was a correlation between their behaviors (p < 0.001, Spearman Correlation Coefficient = 0.4).

CONCLUSION

It seems that the education provided in OHPS had positive effects on increasing students' awareness and to some extent, the knowledge, attitude and practice of the parents.

Implementação do Programa Saúde na Escola: relação com aspectos da saúde bucal dos estudantes

RESUMO O estudo objetivou investigar a associação entre a implementação do Programa Saúde na Escola (PSE) e aspectos relacionados com a saúde bucal de adolescentes escolares que frequentam escolas públicas no Brasil. Foi realizado estudo transversal exploratório utilizando dados da Pesquisa Nacional de Saúde Escolar (PeNSE) 2015 em uma amostra de 81.154 estudantes de 13 a 15 anos frequentando escolas públicas das capitais, Distrito Federal e interior. Os dados foram obtidos por meio de questionários respondidos pelos alunos e responsáveis pelas escolas. Foi realizada análise bivariada de associação entre a variável ‘implementação das ações do PSE pela escola’ (Sim/Não) e aspectos relativos à saúde bucal dos estudantes. Em comparação com escolas sem implementação do PSE, as que haviam implementado o Programa apresentavam melhores indicadores de comportamento (consumo de alimentos com açúcar adicionado, cigarro e álcool); venda de alimentos saudáveis ou com açúcar adicionado; existência de grupo/comitê de saúde, ações do Programa Mais Educação e ações em conjunto com a Unidade Básica de Saúde (p<0,05). Concluiu-se que houve associação entre a implementação do PSE e aspectos mais favoráveis relacionados com a saúde bucal, referentes a alimentação, uso de cigarro e álcool entre os escolares, e ações de saúde e educação nas escolas.

Implementation of the School Health Program: relationship with aspects of students’ oral health

ABSTRACT This study aimed to investigate the association between the School Health Program (PSE) implementation and aspects related to the oral health of adolescent students attending public schools in Brazil. An exploratory cross-sectional study was conducted using data from the 2015 National School Health Survey (PeNSE) in a sample of 81,154 students aged 13 to 15 in the capitals, Federal District, and inland cities. Data were retrieved from questionnaires answered by students and those responsible for the schools. We performed a bivariate analysis of the association between the variable ‘implementation of PSE actions by the school’ (Yes/No) and aspects related to the students’ oral health. Compared to schools without PSE implementation, those that had implemented the Program had better behavioral indicators (consumption of sugar-added foods, cigarettes, and alcohol); selling healthy or sugar-added foods; availability of a health group/committee, and actions of the More Education Program and with Primary Health Care Units (p<0.05). We concluded that there was an association between the implementation of the PSE and more favorable aspects related to oral health regarding the students’ diet, tobacco use, and alcohol consumption, and school health and education actions.

Effectiveness of a Training Program in School Teachers on the Role of Sugars in Oral and General Health

Background: Schools have a powerful influence on children's development and well-being, and school teachers are considered role models to transmit life values and instill health-related behaviors. The effectiveness of a training program for school teachers in understanding the role of sugars and their impact on oral and overall health has not been previously reported.

Aim: The present study aimed to assess the effectiveness of a training program for school teachers on the role of sugars in oral and general health.

Methods: An interventional study was carried out on 308 Kendriya Vidyalaya Sangathan school teachers to evaluate the effectiveness of a training program in improving school teachers' knowledge of the role of sugars in oral and overall health. The training program was carried out using a training module, and a validated questionnaire was utilized to assess school teachers' knowledge before and after the training program.

Results: The overall evaluation of mean knowledge change scores revealed significantly higher scores after the training program (8.12 ±1.58) when compared with the pre-training scores (6.84±1.66)

Conclusion: A training program on the role of sugars in oral and general health effectively improved school teachers' knowledge. 

“Oral health as an important milieu for social and mental health”: Perspectives of adolescents emerging from a qualitative study

Background

Recent evidence showed that the prevalence of oral diseases is still high among adolescents in many developing countries, including Nigeria. It therefore has becomes pertinent to focus on appropriate oral health interventions to promote oral health among them. This necessitates investigating the perspectives of adolescents, who are the major stakeholders, on the importance of oral health as baseline data needed in planning appropriate primary interventions.

Aim

The aim of the study was to explore the perspectives of adolescents on the importance of oral health.

Methods

An explorative qualitative study was conducted among adolescents attending senior secondary school I (grade 10) in the metropolis of Ibadan, Nigeria. A total of 12 focus group discussions were conducted among 120 adolescents aged 14 to 19 years. The discussions were transcribed verbatim, and triangulation and organization, as well as thematic analysis, of data were carried out.

Results

Some adolescents had positive perceptions of oral health and valued it as highly important, although some had contrary views and believed oral health was unimportant. Oral health is described as being integral to general health, is associated with eating and communication, is a means of survival and confidence building, and is a prelude to attract the opposite gender. Adolescents perceived the need for oral health education and dental treatment.

Conclusion

Adolescents have mixed perspectives on the importance of oral health; while some valued it as highly important, others believed it was of no significance. Those who valued oral health as important described it as a milieu for general health, human survival, and social and mental health and thus requested for oral health promotion in schools.

Peer-led oral health education model for elementary school-aged children in British Columbia, Canada

Objective

To examine the effectiveness of peer-led preventive oral health education for elementary school-aged children.

Methods

A controlled, non-randomized interventional study included children in grades 4 to 6 (N = 372) from 6 schools in British Columbia, Canada. The control group (3 schools) received a class-based lecture on oral health. In the intervention group (3 schools), each sixth grader mentored a small group of fourth and fifth graders. The study outcomes were 1) need for oral care referrals (visual screening); 2) oral health knowledge (self-reports); 3) oral self-care practice (OSC-P); and 4) oral self-care skills (OSC-S). Assessments of OSC-P and OSC-S were based on disclosed dental biofilm levels. Study group comparisons were done at baseline and 8 to 12 months.

Results

A high need for oral care referrals was found, with a substantial reduction achieved during the study period. Dietary knowledge improved minimally in the intervention group. In both study groups and within age groups, there was a wide variation in OSC-P and OSC-S. Overall, children's OSC-P scores were substantially higher than their OSC-S scores. Oral self-care outcomes improved over time in both groups (except for fourth graders in the control group), with a more substantial improvement in the intervention group. From baseline to study end, the mean OSC-P improved by 11.9% (intervention group) and 5.9% (control group). Improvement values for OSC-S were 12.8% and 5.2%.

Conclusions

The need for oral care referrals was reduced, but improvement in oral health knowledge was minimal. Oral self-care outcomes improved more in the intervention than in the control group.

Regional Disparities in Caries Experience and Associating Factors of Ghanaian Children Aged 3 to 13 Years in Urban Accra and Rural Kpando

(1) The objective of this socio-epidemiologic cross-sectional study was to investigate caries burdens in Ghanaian children aged 3 to 13 years. The main focus was the analysis of urban-rural disparities and associating socio-demographic and behavioural factors. (2) Standardized caries examination with documentation of decayed, missing, filled deciduous (dmft) and permanent teeth (DMFT) was conducted in 11 school facilities according to WHO guidelines. A parental questionnaire gathered data considering associating factors. Descriptive statistics were used to evaluate their influence on caries prevalence and experience using mean dmft+DMFT, Significant Caries Index (SiC), and Specific Affected Caries Index (SaC). (3) In total, 313 study participants were included (mean age 7.7 ± 3.8 years; 156 urban, 157 rural). The urban region showed slightly higher caries prevalence (40.4% vs. 38.9%). The rural region had higher caries experience in mean dmft+DMFT (1.22 ± 2.26 vs. 0.96 ± 1.58), SiC (3.52 ± 2.73 vs. 2.65 ± 1.71), and SaC (3.15 ± 2.68 vs. 2.37 ± 1.68). Lower education and occupation level of parents and rural residence were associated to higher caries values. Sugary diet showed an inverse relation with caries prevalence and oral hygiene practices supported the generally known etiologic correlation. (4) This study highlights the importance of targeting children vulnerable to caries due to social inequality with adequate preventive means. The implementation of regular dental screening and education, e.g. in schools, may be helpful.

Development and Initial Validation of the Oral Health Activities Questionnaire

Background: The purpose of this study was to introduce a new Oral Health Activities Questionnaire (OHAQ, hereinafter) that examines different activities and behaviours related to the oral hygiene regimen of each analysed subject. Methods: A sample of 658 students was analysed to determine the OHAQ scale’s basic metric characteristics. To determine the construct validity of the OHAQ, descriptive statistics and correlation analysis, as well as differences testing, were applied to groups of subjects on the basis of self-reported oral status measures. Results: The dimensions of oral health activities were determined, and the scales for their measurement were constructed. Females and males differed in the OHAQ questionnaire measures. Significant but low intercorrelations were found among the measures. In the female and male subsample, four different oral health (OH, hereinafter) types of subjects were identified, exhibiting different characteristic behaviours regarding oral health. OHAQ scales showed good discriminant validity, revealing the differences related to specific self-reported oral status measures (e.g., frequency of toothache and the number of filled teeth). Conclusions: The OHAQ represents a satisfactory measurement instrument for determining the level of OH activities and for doing quick and reliable classifications of the participating subjects according to their OH activities and behaviours. The process of further validation and advancements of the OHAQ scales and measures should be continued through a clinical examination of subjects.

OBJECTIVE

The aim: Is an adaptation, determination of psychometric properties, and approbation of the use of COHIP-SF 19 for the needs of dental public health in the Ukrainian sample of children and teenagers.

PATIENTS AND METHODS

Materials and methods: A cross-sectional validation study was conducted on a sample of 236 Ukrainian children aged 6 to 18. The psychometric indicators of the questionnaire were evaluated; analysis of the reliability and internal structure of the methodology based on correlation and factor analysis, calculation of Chronbach's alpha; reliability of re-testing (Intraclass Correlation Coefficient); assessment of convergent and discriminant validity (Mann-Whitney U test, ROC analysis, and correlation analysis). STATISTICA 6.1 (StatSoftInc., № AGAR909E415822FA) was used to analyze the results. The ethics of the study was confirmed by the conclusion of the relevant commission.

RESULTS

Results: After cultural direct and reverse translation of the original version, the Ukrainian version of COHIP-SF 19 UK was obtained. The internal consistency of the subscales and COHIP-SF 19 UK was generally sufficient (Cronbach's alpha is greater than 0.7). Sufficient reliability of retesting, convergent and discriminant validity of the methodology was proved. The presence of a correlation between COHIP-SF 19 UK indicators and self-assessment of children's health and quality of life was determined.

CONCLUSION

Conclusions: The study proved that COHIP-SF 19 UK is a reliable valid method for assessing the quality of life-related to oral health among Ukrainian children and adolescents, and its good psychometric properties are sufficient for research in the field of dental public health.

Impact of Oral Health Educational Interventions on Oral Hygiene Status of Children with Hearing Loss: A Randomized Controlled Trial

Introduction

Oral health is considered as one of the essential components of the overall health of every individual. Maintaining oral health is a gradual process that requires commitment. Children who require special care such as hearing impairment experience difficulty in maintaining oral health primarily due to communication difficulties. This study is aimed at using different interventions to evaluate the improvement of oral hygiene in hearing impaired children.

Materials and Methods

Fifty-nine children were recruited in this study that were allocated randomly into each group with twenty children as follows: group 1: pictorial, group 2: video, and group 3: control. Mean plaque and gingival scores were noted before and after the use of different interventions. Oral hygiene was categorized as “excellent,” “good,” and “fair.” Gingival health was categorized as “healthy,” “mild gingivitis,” and “moderate gingivitis.”

Results

Thirty-four children (57.6%) were from 12-13 years of age bracket, and 25 (42.4%) belonged to 14-16 years of age. Regarding gender, there were 37 (62.7%) males and 22 (37.3%) females. About comparison of mean gingival and plaque scores before and after interventions in each group, a significant difference was found in group 1 (p < 0.001) and group 2 (p < 0.001), as compared to group 3 where the difference in scores was not significant (p > 0.05).

Conclusion

Maintaining oral health requires the compliance of individuals to perform different methods of preventive dentistry, such as tooth brushing and use of dental floss. The use of different oral hygiene educational interventions such as pictorial and video methods have been proven and useful for hearing impaired children in improving oral health.
