Maternal Factors in Relation to Early Childhood Caries Among Preschool Children in Myanmar.

A cross-sectional study was conducted among 3- to 5-year-old preschool children in Yangon City in 2016-2017 to investigate the association between their caries experience and maternal factors. Children's oral examination and questionnaire surveys to their mothers were conducted. Children's caries prevalence was 82.9% with mean dmft of 6.4 ± 4.9. Mean oral health knowledge score of their mothers was 8.5 ± 2.8. Mother's educational level and oral health knowledge were significant predictors of childhood caries. Third- or later-born children were twice more likely to have dental caries than first-born children (P = .022). Mother's regular dental check-up resulted in significantly lower odds ratios for caries development in her child. Children's caries experience was high and mother's oral health knowledge regarding the importance of primary teeth was unsatisfactory. It is, therefore, necessary to improve awareness and attentiveness for prevention of childhood caries among parents and guardians in Myanmar.
