ObjectivesEarly Childhood Caries (ECC) can negatively impact the lives of young children, despite being preventable. The purpose of this study was to utilize available data in Alaska to describe changes in parent reports of ECC, and identify factors related to ECC.MethodsThe Childhood Understanding Behaviors Survey (CUBS) is a population‐based survey of parents of 3‐year‐old children and was utilized to describe changes in: parent‐reported ECC among children with a dental visit, access to and or utilization of dental care, and consumption of three or more cups of sweetened beverages between 2009–2011 and 2016–2019. Logistic regression modeling was used to explore factors associated with parent‐reported ECC among children with a dental visit.ResultsOver time, a significantly smaller proportions of parents whose 3‐year‐old child had seen a dental professional reported ECC. Additionally, a smaller proportion of parents reported three or more cups of sweetened beverage consumption by their child, while larger proportions had seen a dental professional by age 3. Factors associated with parent‐reported ECC included consumption of three or more cups of sweetened beverages, and enrollment in Medicaid or Tribal health care insurance, while protective factors included a parent earning a college degree, and military insurance.ConclusionsAlthough at the statewide level, improvements were observed in parent‐reported measures over time, regional disparities were apparent. Social and economic factors as well as excessive consumption of sweetened beverages appear to play important roles in ECC. CUBS data can help identify trends in ECC within Alaska.
