چکیده

Background and aim: Early loss of deciduous teeth has negative effects on chewing function, aesthetics, self-esteem and permanent dentition. This study aimed to evaluate the prevalence of premature primary tooth loss and the contributing factors in children aged ۳۶ -۷۱ months in Babol city (North of Iran).Methods: In this cross-sectional study, ۵۵۸ heathy preschool children underwent oral examination to record the type and frequency of premature tooth loss and Silness-Loe plaque index. The parents were then asked to fill out a questionnaire about the related factors. Data were evaluated by SPSS (v۲۳) and were analyzed using one-way ANOVA and independent-samples t-test and multiple linear regression analysis. The level of significance was set at p ≤ ۰.۰۵.Results: The frequency rate of missing primary teeth was ۱.۵۶% estimated in ۱۳.۶۲% of children. The mean number of missing teeth showed a significant difference among different subgroups of children classified based on parent’s education (p=۰.۰۰۱), socio-economic status (p=۰.۰۰۱), child's age (p=۰.۰۲), plaque index (p=۰.۰۰۱), frequency of consumption of cariogenic snacks (p=۰.۰۰۱) and brushing (p=۰.۰۰۱). According to multiple linear regression test, Father's educational level, socio-economic status, plaque index, and frequency of consumption of cariogenic snacks were correlated with the number of missing teeth.Conclusion: Less than one-seventh of children had at least one premature missing primary tooth. Child's age, parent’s educational level, socio-economic status, frequency of consumption of cariogenic snacks, plaque index and brushing are related to premature primary tooth loss.
