Improving children's oral health: an interdisciplinary research framework

Evaluating the type of pediatric dental care use in the context of neighborhood opportunity

BACKGROUND

Increasing evidence supports the influence of neighborhood factors on health care use and outcomes. This study measured the association between area-level social determinants of health (SDH) and type of dental care use among Ohio pediatric Medicaid beneficiaries.

METHODS

A retrospective dental claims analysis was completed for children aged 1 through 5 years enrolled in Ohio Medicaid with a dental visit in 2017. Dental care use was measured from 2017 through 2021 as 1 of 4 visit types: (1) preventive, (2) caries treatment, (3) dental general anesthesia (GA), and (4) dental emergency department. The Ohio Children's Opportunity Index defined area-level SDH at the census tract level. Exploratory analysis included descriptive statistics of area-level SDH for each outcome. Poisson regression models were developed to examine the associations between the number of each dental care use outcome and Ohio Children's Opportunity Index quintiles. Visualizations were facilitated with geospatial mapping.

RESULTS

Fifty-six percent of children (10,008/17,675) had caries treatment visits. Overall area-level SDH were positively associated with preventive (fifth vs first quintile incidence rate ratio [IRR], 1.09; 95% CI, 1.07 to 1.12), caries treatment (fifth vs first quintile IRR, 1.16; 95% CI, 1.08 to 1.24), and dental GA visits (fifth vs first quintile IRR, 2.13; 95% CI, 1.13 to 4.01).

CONCLUSIONS

Children with preventive, caries treatment, and dental GA visits were more likely to live in neighborhoods with better SDH. Future efforts should investigate the mechanisms by which area-level factors influence dental access and use.

PRACTICAL IMPLICATIONS

Neighborhood factors influence pediatric dental care use. Patient home addresses might add value to caries risk assessment tools and efforts by care networks to optimize efficient care use.

The importance of promoting oral health in schools: a pilot study

Promotion of oral health has an essential role in the maintenance of teeth in adults. However, health education must start from an early age, in order to monitor the child's growth and prevent pathologies. Schools are in charge of the overall education of children and of guidance to parents but could also be engaged in the promotion of oral health, supported and counseled by pediatricians and dentists. The purpose of this pilot study is to evaluate whether school age children could be taught, successfully, basic oral sciences and dental hygiene, by a professional, during school hours. In this pilot study, an anonymized test was administered to 45 children of age between 8 and 10, both before and after an interactive lecture on oral health, to assess the effectiveness of the lesson and acquisition by the children of knowledge on oral health. After the presentation, the majority of the children were able to answer correctly to the questionnaire that was given to them (test, retest) which was related to dental anatomy and pathology (number of teeth, cavities, halitosis), and dental hygiene tools and practices (brushes, floss, mouth wash, tongue scrapers). The children seemed to be receptive to learning while in school, and a specific educational session of dental hygiene and oral health seems to be the right approach to ensure children can identify dental hygiene tools and use them appropriately.

Guardian Reports of Children's Sub-optimal Oral Health Are Associated With Clinically Determined Early Childhood Caries, Unrestored Caries Lesions, and History of Toothaches

Background: Parents'/guardians' perceptions of their children's oral health are useful proxies of their clinically determined caries status and are known to influence dental care-seeking behavior. In this study, we sought to examine (1) the social and behavioral correlates of fair/poor child oral health reported by guardians and (2) quantify the association of these reports with the prevalence of early childhood caries (ECC), unrestored caries lesions and toothaches. Methods: We used guardian-reported child oral health information (dichotomized as fair/poor vs. excellent/very good/good) obtained via a parent questionnaire that was completed for n = 7,965 participants (mean age = 52 months; range = 36-71 months) of a community-based, cross-sectional epidemiologic study of early childhood oral health in North Carolina between 2016 and 2019. Social, demographic, oral health-related behavioral data, and reports on children's history of toothaches (excluding teething) were collected in the same questionnaire. Unrestored ECC (i.e., caries lesions) was measured via clinical examinations in a subset of n = 6,328 children and was defined as the presence of one or more tooth surfaces with an ICDAS ≥ 3 caries lesion. Analyses relied on descriptive and bivariate methods, and multivariate modeling with average marginal effect (A.M.E.) estimation accounting for the clustered nature of the data. Estimates of association [prevalence ratios (PR) and adjusted marginal effects (AME) with 95% confidence intervals (CI)] were obtained via multilevel generalized linear models using Stata's svy function and accounting for the clustered nature of the data. Results: The prevalence of fair/poor oral health in this sample was 15%-it increased monotonically with children's age, was inversely associated with parents' educational attainment, and was higher among Hispanics (21%) and African Americans (15%) compared to non-Hispanic whites (11%). Brushing less than twice a day, not having a dental home, and frequently consuming sugar-containing snacks and beverages were significantly associated with worse reports (P < 0.0005). Children with fair/poor reported oral health were twice as likely to have unrestored caries lesions [prevalence ratio (PR) = 2.0; 95% confidence interval (CI) = 1.8-2.1] and 3.5 times as likely to have experienced toothaches [PR = 3.5; 95% CI = 3.1-3.9] compared to those with better reported oral health. Conclusions: Guardian reports of their children's oral health are valuable indicators of clinical and public health-important child oral health status. Those with fair/poor guardian-reported child oral health have distinguishing characteristics spanning socio-demographics, oral-health related practices, diet, and presence of a dental home.

Cohort Profile: ZOE 2.0-A Community-Based Genetic Epidemiologic Study of Early Childhood Oral Health

Early childhood caries (ECC) is an aggressive form of dental caries occurring in the first five years of life. Despite its prevalence and consequences, little progress has been made in its prevention and even less is known about individuals' susceptibility or genomic risk factors. The genome-wide association study (GWAS) of ECC ("ZOE 2.0") is a community-based, multi-ethnic, cross-sectional, genetic epidemiologic study seeking to address this knowledge gap. This paper describes the study's design, the cohort's demographic profile, data domains, and key oral health outcomes. Between 2016 and 2019, the study enrolled 8059 3-5-year-old children attending public preschools in North Carolina, United States. Participants resided in 86 of the state's 100 counties and racial/ethnic minorities predominated-for example, 48% (n = 3872) were African American, 22% white, and 20% (n = 1611) were Hispanic/Latino. Seventy-nine percent (n = 6404) of participants underwent clinical dental examinations yielding ECC outcome measures-ECC (defined at the established caries lesion threshold) prevalence was 54% and the mean number of decayed, missing, filled surfaces due to caries was eight. Nearly all (98%) examined children provided sufficient DNA from saliva for genotyping. The cohort's community-based nature and rich data offer excellent opportunities for addressing important clinical, epidemiologic, and biological questions in early childhood.

Design and sample characteristics of COordinated Oral health Promotion (CO-OP) Chicago: A cluster-randomized controlled trial

COordinated Oral health Promotion (CO-OP) Chicago is a two-arm cluster-randomized trial with a wait-list control. The primary aim is to evaluate the efficacy of an oral health community health worker (CHW) intervention to improve oral health behaviors in low-income, urban children under the age of three years. Exploratory aims will determine cost-effectiveness, and if any CHW intervention impact on child tooth brushing behaviors varies when CHWs are based out of a medical clinic compared to a community setting. This paper describes progress toward achieving these aims. Participating families were recruited from community social service centers and pediatric primary care medical clinics in Cook County, Illinois. Sites were cluster-randomized to CHW intervention or usual services (a wait-list control). The intervention is oral health support from CHWs delivered in four visits to individual families over one year. The trial sample consists of 420 child/caregiver dyads enrolled at the 20 participating sites over 11 months. Participant demographics varied across the sites, but primary outcomes values at baseline did not. Data on brushing frequency, plaque, and other oral health behaviors are collected at three timepoints: baseline, 6-, and 12-months. The primary analysis will assess differences in caregiver-reported child brushing frequency and observed plaque score between the two arms at 12-months. The trial is currently in the active intervention phase. The trial's cluster-randomized controlled design takes a real-world approach by integrating into existing health and social service agencies and collecting data in participant homes. Results will address an important child health disparity. ClinicalTrials.gov identifier: NCT03397589. CLINICAL TRIAL REGISTRATION: University of Illinois at Chicago Protocol Record 2017-1090.

The policy implementation gap of school oral health programmes in Tshwane, South Africa: a qualitative case study

BACKGROUND

School going children across the world continue to experience high levels of untreated dental diseases. The South African Oral Health policy documents present measures to address the oral health needs of children in school settings, yet the burden of oral disease in the country is over 50% among primary school children.

METHODS

Our study therefore sought to assess the implementation of school oral health programmes in Tshwane in line with policy recommendations using the Walt & Gilson policy analysis triangle. A qualitative explanatory case study was undertaken using a combination of data from direct observations and interviews. The case analysis involved assessing the processes of providing school oral health programmes that were offered at 10 schools in Tshwane. The measuring tools included process maps and an interview guide.

RESULTS

The results found that policy implementation was affected by poor prior planning, inadequate resources, poor school infrastructure and lack of support from key stakeholders. Furthermore, inconsistencies in policy interpretation by management, coupled with the fact that the oral hygienists were not conversant with the policy hampered delivery of the policy content. The variations in policy implementation observed were often at the discretion of the oral hygienist in response to contextual challenges.

CONCLUSION

There was policy and practice misalignment and variations in the processes of implementing oral health programmes across the 10 schools. Hence regular monitoring, evaluation and root cause analysis is recommended for such programmes in order to make informed decisions on contextually relevant and standardised programme modifications.

The building blocks of precision oral health in early childhood: the ZOE 2.0 study

Improving children's oral health is a long-standing area of priority and sustained efforts by many stakeholders. Despite these efforts, dental caries, particularly early childhood caries (ECC), persists as a clinical and dental public health problem with multilevel consequences. Despite recent successes in the non-restorative management of dental caries, remarkably little has been done in the domain of ECC prevention. There is promise and expectation that meaningful improvements in early childhood oral health and ECC prevention can be made via the advent of precision medicine in the oral health domain. We posit that precision dentistry, including genomic influences, may be best examined in the context of well-characterized communities (versus convenience clinical samples) and the impact of contextual factors including geography and social disadvantage may be explainable via mechanistic (i.e., biological) research. This notion is aligned with the population approach in precision medicine, which calls for the latter to be predictive, preventive, personalized, and participatory. The article highlights research directions that must be developed for precision dentistry and precision dental public health to be realized. In this context, we describe the rationale, activities, and early insights gained from the ZOE 2.0 study - a large-scale, community-based, genetic epidemiologic study of early childhood oral health. We anticipate that this long-term research program will illuminate foundational domains for the advancement of precision dentistry and precision dental public health. Ultimately, this new knowledge can help catalyze the development of effective preventive and therapeutic modalities via actions at the policy, community, family, and person level.

Follow-up of an Intervention to Reduce Dental Caries in Indigenous Australian Children: A Secondary Analysis of a Randomized Clinical Trial

Importance

Testing the long-term usefulness of a childhood intervention and determining the best age of implementation are important for translation and policy change.

Objectives

To investigate among children aged 3 years the long-term effectiveness an intervention that aimed to reduce dental caries among South Australian Aboriginal children and to assess if children in the delayed intervention (DI) group had any benefit from the intervention from ages 2 to 3 years and if the intervention usefulness was greater when delivered between pregnancy and age 2 years (immediate intervention [II] vs ages 2 to 3 years [DI]).

Design, Setting, and Participants

Secondary analysis of a randomized clinical trial. The study enrolled 448 pregnant women across South Australia, Australia, at baseline (February 1, 2011, to May 30, 2012), with 223 randomly allocated to the II group and 225 to the DI group. Three-year follow-up data were collected November 2014 to February 2016.

Interventions

The intervention comprised dental treatment to mothers, fluoride varnish application to children, and motivational interviewing delivered together with anticipatory guidance. This was delivered during pregnancy and at child ages 6, 12, and 18 months for the II group and at child ages 24, 30, and 36 months for the DI group.

Main Outcomes and Measures

The mean number of decayed teeth measured at child age 3 years.

Results

There were 324 children at age 3 years (52.3% male). The mean number of decayed teeth at age 3 years was 1.44 (95% CI, 1.38-1.50) for the II group and 1.86 (95% CI, 1.89-2.03) for the DI group (mean difference, -0.41; 95% CI, -0.52 to -0.10). The predicted mean number of decayed teeth at age 3 years for the DI group was 2.15. Between ages 2 and 3 years, the caries increment for the II group was 0.82 (95% CI, 0.75-0.89), compared with 0.97 (95% CI, 0.87-1.17) for the DI group (P = .05).

Conclusions and Relevance

At the 3-year follow-up, II children had less dental caries than DI children, DI children developed dental caries at a lower trajectory than predicted had the intervention not been received at ages 2 to 3 years, and the caries increment was less between ages 2 to 3 years among II children compared with DI children. This study suggests that the best time to implement the intervention is earlier rather than later infancy.

What really happens in the home: a comparison of parent-reported and observed tooth brushing behaviors for young children

Background

Most studies of tooth brushing behaviors rely on self-report or demonstrations of behaviors conducted in clinical settings. This study aimed to determine the feasibility of objective assessment of tooth brushing behaviors in the homes of high-risk children under three years old. We compared parent self-report to observations to determine the accuracy of self-report in this population.

Methods

Forty-five families were recruited from dental and medical clinics and a community social service agency. Research staff asked questions about oral health behaviors and observed tooth brushing in the homes. Brushing was also video-recorded. Video-recordings were coded for brushing behaviors by staff that did not collect the primary data; these abstracted data were compared to those directly observed in homes.

Results

Most families were Hispanic (76%) or Black (16%) race/ethnicity. The majority of parents had a high school education (42%) or less (24%). The mean age of children was 21 months. About half of parents reported brushing their child’s teeth twice a day (58%). All parents tried to have their children brush, but three children refused. For brushing duration, 70% of parents reported differently than was observed. The average duration of brushing was 62.4 s. Parent report of fluoride in toothpaste frequently did not match observations; 39% said they used toothpaste with fluoride while 71% actually did. Sixty-eight percent of parents reported using a smear of toothpaste, while 61% actually did. Brushing occurred in a variety of locations and routines varied. Abstracted data from videos were high in agreement for some behaviors (rinse with water, floss used, brushing location, and parent involvement: Kappa 0.74–1.0). Behaviors related to type of brushing equipment (brushes and toothpaste), equipment storage, and bathroom organization and clutter had poor to no agreement.

Conclusions

Observation and video-recording of brushing routines and equipment are feasible and acceptable to families. Observed behaviors are more accurate than self-report for most components of brushing and serve to highlight some of the knowledge issues facing parents, such as the role of fluoride.

Oral Health Knowledge and Behavior among Adults in the United Arab Emirates

Background

The prevalence of periodontal diseases is increasing in the United Arab Emirates (UAE) despite a worldwide decline in the prevalence of dental caries among children and adolescents. The aims of this study were to determine the levels of oral health knowledge and health-related behavior in adult UAE residents, and the relationship between these variables and oral health.

Methods

A descriptive cross-sectional survey with nonprobability sampling was used in this study. A sample of 630 adults residing in the UAE completed an oral health survey to assess their oral health knowledge and behavior. Mean oral health knowledge and behavior scores were calculated and correlated with population demographic and behavioral variables.

Results

Participants were found to have an acceptable oral health knowledge score (OHKS) of 10.50 (2.36) where 62 % of participants answered the questions correctly. Results showed that age, gender, nationality, smoking, and physical activity were significantly associated with the knowledge score. However, only gender, nationality, and smoking predicted oral health knowledge scores after further regression analysis. On the other hand, the mean oral health behavior score (OHBS) for all participants was 8.91 (2.29); 98% of all participants practiced at least an acceptable level of oral behavior and 53% practiced a good to perfect level. Age, gender, educational level, employment status, insurance status, marital status, nationality, smoking, and physical activity showed significant statistical association with the score of behaviors related to oral health. Only gender, number of diabetes sessions attended, and health information sources used remained significant after further regression analysis.

Conclusion

Further efforts are required to spread awareness about oral health and encourage the UAE population to develop healthy oral habits. Such programs will decrease the occurrence and burden of many chronic oral diseases especially periodontal diseases.

Measurement of Early Childhood Oral Health for Research Purposes: Dental Caries Experience and Developmental Defects of the Enamel in the Primary Dentition

Epidemiological investigations of early childhood oral health rely upon the collection of high-quality clinical measures of health and disease. However, ascertainment of valid and accurate clinical measures presents unique challenges among young, preschool-age children. The paper presents a clinical research protocol for the conduct of oral epidemiological examinations among children, implemented in ZOE 2.0, a large-scale population-based genetic epidemiologic study of early childhood caries (ECC). The protocol has been developed for the collection of information on tooth surface-level dental caries experience and tooth-level developmental defects of the enamel in the primary dentition. Dental caries experience is recorded using visual criteria modified from the International Caries Detection and Assessment System (ICDAS), and measurement of developmental defects is based upon the modified Clarkson and O'Mullane Developmental Defects of the Enamel Index. After a dental prophylaxis (toothbrushing among all children and flossing as needed), children's teeth are examined by trained and calibrated examiners in community locations, using portable dental equipment, compressed air, and uniform artificial light and magnification conditions. Data are entered directly onto a computer using a custom Microsoft Access-based data entry application. The ZOE 2.0 clinical protocol has been implemented successfully for the conduct of over 6000 research examinations to date, contributing phenotype data to downstream genomics and other "omics" studies of ECC and DDE, as well as traditional clinical and epidemiologic dental research.

Formative research implications on design of a randomized controlled trial for oral health promotion in children

BACKGROUND

The COordinated Oral health Promotion (CO-OP) Chicago trial will test the efficacy of a community health worker (CHW) intervention to improve oral health behaviors for children at high risk for early childhood caries. Before implementing the cluster-randomized controlled trial, we conducted a formative assessment to determine the final design. We used qualitative methods to assess the feasibility and acceptability of the proposed recruitment, data collection, and intervention plan.

METHODS

Key informant interviews (N = 37) and site observations were conducted at 10 pediatric primary care clinics and 10 Special Supplemental Nutrition Program for Women Infant and Children (WIC) centers to gain insight from providers and administrators at the locations where recruitment and intervention will occur. Eight focus groups (N = 68) were conducted with caregivers of children to capture the parent perspective. Conceptual coding methods from grounded theory were applied to organize the data into the final themes.

RESULTS

Families, clinics, and WIC centers were all very interested in additional supports for oral health and were enthusiastic about CHWs. Challenges included competing family priorities that might interfere in study enrollment and intervention efficacy. Physical space for enrollment and intervention delivery was a major barrier for some sites. Home visits for data collection and intervention delivery would be unacceptable for some families. These challenges and barriers prompted us to make major changes in our trial design. We opened the option for data collection to occur in multiple locations. We eliminated the home-only arm of the trial. Clinics and WIC centers that are randomized to the non-intervention arm will now have CHWs available at the study conclusion. Finally, we aligned the CHW oral health topics to the needs of families.

CONCLUSIONS

We conducted this comprehensive formative assessment to determine the feasibility and acceptability of the CO-OP Chicago trial. While overall acceptance of the trial was high, the results highlighted specific issues with the proposed trial implementation plan and led to several critical design changes. This type of formative work requires a significant upfront investment but we expect it will translate into savings through better recruitment, retention, intervention implementation and adherence, and result dissemination.

Prenatal Maternal Factors, Intergenerational Transmission of Disease, and Child Oral Health Outcomes

This article reviews maternal prenatal risk factors for caries in children and intergenerational transmission of caries, emphasizing early interventions for pregnant women and mother-infant pairs. A growing body of evidence focuses on maternal interventions. Studies suggest that early prenatal clinical and educational interventions are effective at reducing mother-child mutans streptococci (MS) transmission and delaying colonization and caries in young children. Dental screenings and anticipatory guidance about maternal and infant oral health should be included in prenatal care and pediatric well visits. Dental care during pregnancy is safe and recommended and can reduce maternal MS levels. Infants should visit a dentist by age 1.

Exploring the genomic basis of early childhood caries: a pilot study

OBJECTIVE

A genetic component in early childhood caries (ECC) is theorized, but no genome-wide investigations of ECC have been conducted. This pilot study is part of a long-term research program aimed to: (1) determine the proportion of ECC variance attributable to the human genome and (2) identify ECC-associated genetic loci.

METHODS

The study's community-based sample comprised 212 children (mean age=39 months; range = 30-52 months; males = 55%; Hispanic/Latino = 35%, African-American = 32%; American Academy of Pediatric Dentistry definition of ECC prevalence = 38%). Approximately 2.4 million single nucleotide polymorphisms (SNPs) were genotyped using DNA purified from saliva. A P < 5 × 10^-8 criterion was used for genome-wide significance. SNPs with P < 5 × 10^-5 were followed-up in three independent cohorts of 921 preschool-age children with similar ECC prevalence.

RESULTS

SNPs with minor allele frequency ≥5% explained 52% (standard error = 54%) of ECC variance (one-sided P = 0.03). Unsurprisingly, given the pilot's small sample size, no genome-wide significant associations were found. An intergenic locus on 4q32 (rs4690994) displayed the strongest association with ECC [P = 2.3 × 10^-6 ; odds ratio (OR) = 3.5; 95% confidence interval (CI) = 2.1-5.9]. Thirteen loci with suggestive associations were followed-up - none showed evidence of association in the replication samples.

CONCLUSION

This study's findings support a heritable component of ECC and demonstrate the feasibility of conducting genomics studies among preschool-age children.

Lessons learnt in recruiting disadvantaged families to a birth cohort study

BACKGROUND

Dental decay in early childhood can be prevented by a model based on shared care utilising members of primary care team such as Child and Family Health Nurses (CFHNs) in health promotion and early intervention. The aims of this study were to identify the facilitators and barriers faced by CFHNs in recruiting research participants from disadvantaged backgrounds to a birth cohort study in South Western Sydney, Australia.

METHODS

Child and Family Health Nurses recruited mothers-infants dyads (n = 1036) at the first post-natal home visit as part of Healthy Smiles Healthy Kids Study, an ongoing birth cohort study in South Western Sydney. The nurses (n = 19) were purposively selected and approached for a phone based in-depth semi-structured interview to identify the challenges faced by them during the recruitment process. Interviews were audio-recorded, subsequently transcribed verbatim and analysed by thematic analysis.

RESULTS

The nurses found the early phase of parenting was an overwhelming stage for parents as they are pre-occupied with more immediate issues such as settling and feeding a newborn. They highlighted some key time-points such as during pregnancy and/or around the time of infant teething may be more appropriate for recruiting families to dental research projects. However, they found it easier to secure the family's attention by offering incentives, gifts and invitations for free oral health services. The use of web-based approaches and maintaining regular contact with the participants was deemed crucial for long-term research. Cultural and linguistic barriers were seen as an obstacle in recruiting ethnic minority populations and the need for cultural insiders in the research team was deemed important to resolve the challenges associated with conducting research with diverse cultures. Finally, nurses identified the importance of inter-professional collaboration to provide easier access to recruiting research participants.

CONCLUSIONS

This study highlighted the need for multiple time-points and incentives to facilitate recruitment and retention of disadvantaged communities in longitudinal research. The need for cultural insiders and inter-professional collaboration in research team are important to improve research participation.

Road to the Future: Priorities for Child Health Services Research

BACKGROUND

Prior health services research (HSR) agendas for children have been published, but major ones are now over 15 years old and do not reflect augmented understanding of the drivers and determinants of children's health; recent changes in the organization, financing, and delivery of health care; a growing emphasis on population health; and major demographic shifts in the population. A policy-relevant research agenda that integrates knowledge gained over the past 2 decades is essential to guide future child HSR (CHSR). We sought to develop and disseminate a robust, domestically focused, policy-oriented CHSR agenda.

METHODS

The new CHSR agenda was developed through a series of consultations with leaders in CHSR and related fields. After each round of consultation, the authors synthesized the previous experts' guidance to help inform subsequent discussions. The multistep process in generation of the agenda included identification of major policy-relevant research domains and specification of high-value research questions for each domain. Stakeholders represented in the discussions included those with expertise in child and family advocacy, adult health, population health, community development, racial and ethnic disparities, women's health, health economics, and government research funders and programs.

RESULTS

In total, 180 individuals were consulted in developing the research agenda. Six priority domains were identified for future research, including both enduring and emerging emphases: 1) framing children's health issues so that they are compelling to policy-makers; 2) addressing poverty and other social determinants of child health and wellbeing; 3) promoting equity in population health and health care; 4) preventing, diagnosing, and treating high priority health conditions in children; 5) strengthening performance of the health care system; and 6) enhancing the CHSR enterprise. Within these 6 domains, 40 specific topics were identified as the most pertinent for future research. Three overarching and crosscutting themes that affect research across the domains were also noted: the need for syntheses to build on the current, and sometimes extensive, evidence base to avoid duplication; the interrelated nature of the domains, which could lead to synergies in research; and the need for multidisciplinary collaborations in conducting research because research studies will look beyond the health sector.

CONCLUSIONS

The priorities presented in the agenda are policy-oriented and include a greater emphasis on how findings are framed and communicated to support action. We expect that the agenda will be useful for immediate uptake by investigators and research funders.

Precision Dentistry in Early Childhood: The Central Role of Genomics

Pediatric oral health is determined by the interaction of environmental factors and genetic influences. This is the case for early childhood caries, the most common disease of childhood. The complexity of exogenous-environmental factors interacting with innate biological predispositions results in a continuum of normal variation, as well as oral health and disease outcomes. Optimal oral health and care or precision dentistry warrants comprehensive understanding of these influences and tools enabling intervention on modifiable factors. This article reviews the current knowledge of the genomic basis of pediatric oral health and highlights known and postulated mechanistic pathways of action relevant to early childhood caries.

Healthy Futures: Engaging the oral health community in childhood obesity prevention - Conference summary and recommendations

Childhood obesity is a major public health problem. An association between obesity and dental caries, the most prevalent disease of childhood, has been identified. One explanation for the association is that consumption of sugar-sweetened beverages and frequent snacking on carbohydrate-rich foods are common risk factors for development of both obesity and caries. The Robert Wood Johnson Foundation (RWJF) has been at the forefront of national efforts to promote healthy weight in children. As part of these efforts, RWJF sponsored the Healthy Futures: Engaging the Oral Health Community in Childhood Obesity Prevention National Conference, held on November 3-4, 2016, at Georgetown University in Washington, DC. The aim of the conference was to increase awareness of evidence-based recommendations; identify strategies; and promote collaborative efforts that oral health professionals, oral-health-related organizations, and others can employ to prevent childhood obesity. This report summarizes the findings presented at the conference and discusses their implications. The report also reviews recommendations made in the areas of research, education, and policy that resulted from the conference.

Framing Young Childrens Oral Health: A Participatory Action Research Project

BACKGROUND AND OBJECTIVES

Despite the widespread acknowledgement of the importance of childhood oral health, little progress has been made in preventing early childhood caries. Limited information exists regarding specific daily-life and community-related factors that impede optimal oral hygiene, diet, care, and ultimately oral health for children. We sought to understand what parents of young children consider important and potentially modifiable factors and resources influencing their children's oral health, within the contexts of the family and the community.

METHODS

This qualitative study employed Photovoice among 10 English-speaking parents of infants and toddlers who were clients of an urban WIC clinic in North Carolina. The primary research question was: "What do you consider as important behaviors, as well as family and community resources to prevent cavities among young children?" Five group sessions were conducted and they were recorded, transcribed verbatim and analyzed using qualitative research methodology. Inductive analyses were based on analytical summaries, double-coding, and summary matrices and were done using Atlas.ti.7.5.9 software.

FINDINGS

Good oral health was associated with avoidance of problems or restorations for the participants. Financial constraints affected healthy food and beverage choices, as well as access to oral health care. Time constraints and occasional frustration related to children's oral hygiene emerged as additional barriers. Establishment of rules/routines and commitment to them was a successful strategy to promote their children's oral health, as well as modeling of older siblings, cooperation among caregivers and peer support. Community programs and organizations, social hubs including playgrounds, grocery stores and social media emerged as promising avenues for gaining support and sharing resources.

CONCLUSIONS

Low-income parents of young children are faced with daily life struggles that interfere with oral health and care. Financial constraints are pervasive, but parents identified several strategies involving home care and community agents that can be helpful. Future interventions aimed to improve children's oral health must take into consideration the role of families and the communities in which they live.

Predicting Dental Caries Outcomes in Children: A "Risky" Concept

In recent years, unprecedented gains in the understanding of the biology and mechanisms underlying human health and disease have been made. In the domain of oral health, although much remains to be learned, the complex interactions between different systems in play have begun to unravel: host genome, oral microbiome with its transcriptome, proteome and metabolome, and more distal influences, including relevant behaviors and environmental exposures. A reasonable expectation is that this emerging body of knowledge can help improve the oral health and optimize care for individuals and populations. These goals are articulated by the National Institutes of Health as "precision medicine" and the elimination of health disparities. Key processes in these efforts are the discovery of causal factors or mechanistic pathways and the identification of individuals or population segments that are most likely to develop (any or severe forms of) oral disease. This article critically reviews the fundamental concepts of risk assessment and outcome prediction, as they relate to early childhood caries (ECC)-a common complex disease with significant negative impacts on children, their families, and the health system. The article highlights recent work and advances in methods available to estimate caries risk and derive person-level caries propensities. It further discusses the reasons for their limited utility in predicting individual ECC outcomes and informing clinical decision making. Critical issues identified include the misconception of defining dental caries as a tooth or surface-level condition versus a person-level disease; the fallacy of applying population-level parameters to individuals, termed privatization of risk; and the inadequacy of using frequentist versus Bayesian modeling approaches to derive individual disease propensity estimates. The article concludes with the notion that accurate caries risk assessment at the population level and "precision dentistry" at the person level are both desirable and achievable but must be based on high-quality longitudinal data and rigorous methodology.

Family Access to a Dentist Study (FADS): A multi-center randomized controlled trial

INTRODUCTION

Many low-income parent/caregivers do not understand the importance of cavity-free primary (baby) teeth and the chronic nature of dental caries (tooth decay). As a consequence, dental preventive and treatment utilization is low even when children are screened in schools and referred for care. This study aims to test a referral letter and Dental Information Guide (DIG) designed using the Common-Sense Model of Self-Regulation (CSM) framework to improve caregivers' illness perception of dental caries and increase utilization of care by children with restorative dental needs.

METHODS

A multi-site randomized controlled trial with caregivers of Kindergarten to 4th grade children in urban Ohio and rural Washington State will compare five arms: (1) CSM referral letter alone; (2) CSM referral letter+DIG; (3) reduced CSM referral letter alone; (4) reduced CSM referral letter+DIG; and (5) standard (control) referral. At baseline, children will be screened at school to determine restorative dental needs. If in need of treatment, caregivers will be randomized to study arms and an intervention packet will be sent home. The primary outcome will be dental care based on a change in oral health status by clinical examination 7 months post-screening (ICDAS sealant codes 1 and 2; restoration codes 3-8; extraction). Enrollment commenced summer 2015 with results in summer 2016.

CONCLUSION

This study uses the CSM framework to develop and test behavioral interventions to increase dental utilization among low-income caregivers. If effective this simple intervention has broad applicability in clinical and community-based settings.

Cultural aspects of ageing and health promotion

The emphasis of Australian Government policy is on the promotion of good health in later life and positive experiences with ageing. Conceptually, a new gerontology framework has replaced the study of disease, decline, loss and disability. Within this framework, health promotion offers a mechanism by which individuals can be assisted to create environments that offer better opportunities for continued participation in society and improved quality of health and self-care. Oral health is instrumental to older people's health, life satisfaction, quality of life and perception of self. Australia is culturally diverse, composed of numerous ethno-cultural groups coexisting within a larger, predominant culture, creating a multicultural and multiracial society. However, despite this cultural diversity, the well documented ageing profile of the Australian population and repeated calls for comprehensive geriatric assessment, the oral health of older adults remains a challenge for oral health providers and for society. A major challenge will be to translate existing knowledge and experience of disease prevention and health promotion into appropriate programmes for older adults. Health promotion is the key to improving oral health in later life as it encourages older adults to be proactive in regard to their health. Therefore, increased efforts should be directed towards identifying opportunities for health promotion activities and the development of community based models that encourage older people to improve and maintain their oral health. Ignoring opportunities for health promotion may increase inequalities in oral health and may lead to even greater demands for curative and oral rehabilitative services from these groups This article firstly provides a brief rationale for oral health promotion. Its second part explores the influence of culture on health beliefs, behaviours and outcomes in older adults and how oral health can relate to cultural background. The last section presents the results of an oral health promotion programme for older adults.

The impact of social determinants on schoolchildren's oral health in Brazil

The aim of this study was to evaluate the impact of socioeconomic status, home environment, and self-perception of health conditions on schoolchildren's dental caries experience. A total of 515 twelve-year-old schoolchildren from Juiz de Fora, State of Minas Gerais, Brazil, were selected into a random multistage sample. The schoolchildren were examined for the presence of caries lesions using the decayed/missing/filled teeth (DMFT) index and categorized as caries-free (DMFT = 0) or with caries experience (DMFT > 0). The participants and their parents were asked to answer a questionnaire about socioeconomic status, home environment, and self-perception of their health conditions. The hierarchical multiple regression model was used to assess the associations, since a binary response variable was assumed. The bivariate analysis revealed that variables at four levels, such as type of school, monthly family income, parents' education, home ownership, number of people living in the household, household overcrowding, parents' perception of their children's oral health, and schoolchildren's self-perception of their oral health (p < 0.05), were significantly associated with children's worse dental caries conditions. The regression model results showed that type of school and monthly family income had a strong negative effect on schoolchildren's dental caries experience (p < 0.05) in the final statistical model, where all levels were included. It was observed that socioeconomic factors were considered a strong risk indicator of schoolchildren's caries experience among the investigated social determinants of oral health.
