App-based oral health promotion interventions on modifiable risk factors associated with early childhood caries: A systematic review.

Background: Early childhood caries (ECC) is a preventable chronic disease. Parents' knowledge and attitudes toward oral healthcare have been associated with higher caries experience in their children. Mobile apps within the context of mHealth interventions are a potential tool for raising awareness and informing parents about their children's oral health. Objectives: The aim of this systematic review was to examine the effectiveness of mobile health apps, targeted at parents and caregivers, for the prevention of ECC. Data sources: A systematic search was carried out in five scientific databases; Embase, CINAHL, MEDLINE, PsycINFO and Web of Science. Study selection and data extraction: Original studies, delivering oral health interventions to parents of children <6 years via smartphones, were included. Both quantitative and qualitative findings from the included studies were extracted. Synthesis: A convergent segregated approach was used to integrate the quantitative and qualitative evidence, followed by side-by-side display and narrative synthesis. Results: Out of 5,953 retrieved articles, five met the inclusion criteria and were included in the review. Three articles reported quantitative findings, while two reported both quantitative and qualitative findings. Four studies reported that a mobile app can be an effective tool to improve the oral health knowledge of parents/caregivers, aiding them in incorporating good oral health habits into their children's daily routines. Conclusion: This review demonstrated that oral health promotion programs delivered through mobile apps to parents could be effective in improving child oral health awareness among parents. There is a need for more high-quality studies with a large number of participants to find out which features of mHealth interventions with parents could effectively be employed to reduce the prevalence of ECC. Further studies and apps should be developed based on evidence-based behaviour change techniques and incorporate features such as gamification to increase the effectiveness and engagement of the target population.

The "Neglected" Relationship Between Child Maltreatment and Oral Health? An International Scoping Review of Research.

Globally, the oral health needs of children who have, or are suspected of having, experienced abuse or neglect has become a focus of concern. It is thus valuable and timely to map the contemporary nature of the research landscape in this expanding field. This review reports the findings of a scoping review of the international empirical literature. The aim was to explore the relationship between child maltreatment and oral health and how this complex issue is addressed in contemporary dental, health, and social work practice. The review identified 68 papers, analysis of which identified three themes: (1) There is a relationship between poor oral health and child maltreatment that is well evidenced but conceptually underdeveloped. (2) There are discrepancies between the knowledge of members of the dental team about child maltreatment and their confidence and aptitude to identify and report child protection concerns. (3) There are areas of local-level policy and practice development that seek to improve working relationships between dentists and health and social work practitioners; however, there is widespread evidence that the oral health needs of this group of vulnerable children are not consistently met. To orientate critical discussion and planning for future research and practice, we present the Patterns, Advances, Gaps, Evidence for practice and Research recommendations (PAGER) framework. The review's findings are likely to be of interest to researchers, practitioners, and policy makers working across dentistry, health and social work.

Childhood obesity and dental caries: an ecological investigation of the shape and moderators of the association.

BACKGROUND: Despite sharing a common risk factor in dietary sugars, the association between obesity and dental caries remains unclear. We investigated the association between obesity and dental caries in young children in England in an ecological study. METHODS: We analysed data from 326 lower tier English local authorities. Data on obesity and dental caries were retrieved from 2014/15 to 2016/17 National Child Measurement Programme and 2016/17 National Dental Epidemiology Programme. We used fractional polynomial models to explore the shape of the association between obesity and dental caries. We also examined the modifying effect of deprivation, lone parenthood, ethnicity, and fluoridation. RESULTS: Best fitting second order fractional polynomial models did not provide better fit than the linear models for the association between obesity and prevalence and severity of dental caries; therefore, the linear model was found suitable. Despite significant association, after adjusting for the effect of deprivation, obesity was neither associated with prevalence (coefficient = 0.2, 95% CI - 0.71, 0.75), nor with severity (coefficient = 0.001, 95% CI - 0.03, 0.03) of dental caries. In fully adjusted models, the proportion of white ethnicity and being in fluoridated areas were associated with a decrease in dental caries. The association between obesity and dental caries was moderated by the effect of deprivation, white ethnicity, and lone parenthood. CONCLUSIONS: The association between obesity and dental caries was linear and moderated by some demographic factors. Consequently, interventions that reduce obesity and dental caries may have a greater impact on specific groups of the population.

Area-level deprivation and oral cancer in England 2012-2016.

BACKGROUND: The relationship between deprivation and oral cancer is complex. We examined magnitude and shape of deprivation-related inequalities in oral cancer in England 2012-2016. METHODS: Oral cancer was indicated by cancers of the lip and oral cavity (ICD10 C00-C06) and lip, oral cavity and pharynx (C00-C14) and deprivation by the Index of Multiple Deprivation. Deprivation inequality in incidence and mortality rates of oral cancer outcomes was measured using the Relative Index of Inequality (RII). Fractional polynomial regression was used to explore the shape of the relationships between deprivation and oral cancer outcomes. Multivariate regression models were fitted with the appropriate functions to examine the independent effect of deprivation on cancer adjusting for smoking, alcohol and ethnicity. RESULTS: Incidence rate ratios (IRRs) and mortality rate ratios (MRRs) were greater for more deprived areas. The RII values indicated significant inequalities for oral cancer outcomes but the magnitude of inequalities were greater for mortality. The relationships between deprivation and oral cancer outcomes were curvilinear. Deprivation, Asian ethnicity and alcohol consumption were associated with higher incidence and mortality rates of oral cancer. CONCLUSION: This is the first study, to our knowledge, exploring the shape of socioeconomic inequalities in oral cancer at neighbourhood level. Deprivation-related inequalities were present for all oral cancer outcomes with a steeper rise at the more deprived end of the deprivation spectrum. Deprivation predicted oral cancer even after accounting for other risk factors.
