Early Childhood Caries and Primary Caregiver Oral Health Literacy in Western Australia: a Systematic Scoping Review

Background: Early childhood caries disproportionately affects vulnerable groups and remains a leading cause of preventable hospital admissions for Western Australian children. The Western Australia State Oral Health Plan seeks to improve child oral health through universal and targeted health promotion initiatives with primary caregivers. These initiatives require evidence of primary caregiver health literacy and baseline data on Early childhood caries. The objective of this systematic scoping review is to understand current oral health literacy of primary caregivers of children aged 0 to 4 years, identify influential socioecological determinants, and identify data on Early childhood caries in the Western Australian context. Methods A systematic scoping review framework identified articles published between 1980 and 2021, using Scopus, PubMed, Medline, CINAHL, PsycINFO, selected article reference lists, and oral health websites. Articles were screened via author consensus, with eight selected. Results Data on early childhood caries in Western Australia is limited; the suggested prevalence of 2.9% based on data over 15 years old, however national data suggests an Early childhood caries prevalence of 3.4–8% of children aged 18 months rising sharply by 36 months of age. Fewer than half the primary caregivers reported following evidence-based oral health recommendations for their young children. Engagement with dentists tended to be reactive. Knowledge of dietary and oral hygiene practices were inconsistent and awareness of the Child Dental Benefit Schedule low. Young children’s oral health status was clearly associated with socioecological factors including socioeconomic status. Conclusions Early childhood caries data and primary care-givers’ oral health literacy evidence are unavailable in Western Australia. To realise the Western Australia State Oral Health Plan, research is required to address this knowledge gap.
