AbstractObjectivesRoutine preventive dental care is important to overall child health and well‐being. However, the experience of adversity in childhood may prevent children from getting adequate preventive care. This study seeks to explore how the prevalence of adverse childhood experiences (ACEs) and the role of a protective adult may be associated with dental care utilization in childhood.MethodsData from the 2016 South Carolina Behavioral Risk Factor Surveillance System (SC BRFSS), which interviews adults eighteen year of age and older, were used in this study. Dental care utilization in childhood was measured as the adult retrospectively reported frequency of dental care in childhood: at least once every 2 years (adequate dental care) or less often than every 2 years (inadequate dental care). ACEs were determined by asking about each of respondent's childhood exposure to eleven childhood experiences, including divorce, parental incarceration, domestic violence, drug and alcohol abuse, mental illness and emotional, physical or sexual abuse. The presence of a protective adult in childhood included respondents who had an adult who made them feel safe and protected during childhood. Descriptive and bivariate statistics explored differences in the adequacy of child dental care by ACE exposure, the presence of a protective adult and selected demographic characteristics. Multivariate regression models were used to examine the impact of counts and types of ACEs and the presence of a protective adult with inadequate childhood dental care.ResultsThe unweighted study sample included 7079 respondents ageing from 18 to 79 years of age Sampling weights were used for all analyses. Among all respondents, 71.7% reported receiving adequate dental care during childhood; 28.3% responded that they received inadequate dental care. Adjusting for sociodemographic characteristics, respondents who experienced four or more ACEs had a higher likelihood of inadequate dental care than respondents who reported no ACEs (aOR 2.79; 95% CI 2.77‐2.82). The odds of reporting inadequate dental care were lower among those grew up with an adult who made them feel safe and protected (aOR 0.38; 95% CI 0.37‐0.39).ConclusionsThe presence of protective factors may mitigate the effects of ACEs on paediatric dental care. This research contributes to the literature through the further identification of the role of dentists in identifying signs of abuse and neglect.
