The relationships among oral health practices, early childhood caries, and oral health-related quality of life in Indonesian preschool children: A cross-sectional study

Objectives: This study aimed at evaluating the relationships among oral health practices, early childhood caries (ECC), and oral health-related quality of life (OHRQoL) in five-year-old children in Indonesia. Materials and Methods: Overall, 266 parent-child pairs (PCPs) from preschools in Jakarta participated in a cross-sectional study. The ECC was clinically assessed by two calibrated screeners using the decayed, missing, and filled teeth (dmft) and the pufa index, which records the presence of severely decayed teeth with visible pulpal involvement (p), ulceration caused by dislocated tooth fragments (u), fistula (f), and abscess (a). The parents of the participating children completed the self-Administered questionnaire comprising SOHO-5p and their oral health practices. The SOHO-5c questionnaire was used to interview the children. Results: The prevalence of ECC was 88.7%, with 35% having pufa index scores greater than 0. There were significant relationships among oral health practices, ECC, and the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) scores. There was also a significant relationship between cariogenic food consumption and the dmft and SOHO-5p scores. There was a significant relationship between ECC and the SOHO-5 scores. All the SOHO-5p variables except smile avoidance because of appearance had a significant relationship with the dmft and pufa variables. Eating and sleeping difficulties were significantly related to the dmft and pufa scores. Conclusion: OHRQoL was found to be related to the dmft and pufa scores, and the parents' perceptions were more strongly correlated than the children's. No significant difference was found in the perceptions indicated by the SOHO-5p and SOHO-5c scores. This suggests that parents can be used as proxies regarding their children's OHRQoL.
