Early Childhood Caries and Related Risk Factors among Myanmar Preschool Childre

다국어 초록 (Multilingual Abstract)

Objective: The purposes of this study were to investigate the prevalence of early childhood caries (ECC) in Myanmar preschool children and to assess the relationship between ECC and its potential risk factors. Methods: A cross-sectional epidemiological study was undertaken among 603 preschool children (3-4 years) from six kindergartens of Yangon city in 2015. Clinical oral examinations of children and questionnaire surveys to guardians were conducted. Results: Overall caries prevalence was 82.9% with mean dmft of 6.42±4.90. Caries prevalence and mean dmft by age were 78.9% and 5.69±4.66 in 3 year-olds, and 87.0% and 7.34±5.03 in 4 year-olds. Longer duration of breast or bottle feeding was significantly associated with higher dental caries experience. Children who took sweet foods or drinks had significantly higher dmft than those who took no sweet foods or drinks. Dental caries prevalence was significantly lower in children who started tooth brushing early. Tooth brushing once a day showed a significantly higher risk of dental caries than tooth brushing twice or more a day. Children who always rinsed after meals were significantly less likely to have dental caries than those who did not rinse at all. Conclusion: ECC is currently a serious oral health problem in Myanmar. Expansion of awareness of dental caries in both parents and oral health professionals would be likely to improve the condition among Myanmar preschool children.
