Correlation between body mass index with anterior crowding and enamel hypoplasia of sundanese children in Bandung

Abstract

Background: Nutrition affects the growth of bones and teeth. Malnutrition can cause teeth to become irregular and undergo enamel hypoplasia (EH). To assess malnutrition, the body mass index (BMI) can be used. Objective: This study aims to analyze the correlation of BMI with anterior crowding and EH in Sundanese children aged 9–12 years. Method: This analytic observational study with a cross-sectional design was done in four public elementary schools in Bandung taken by random cluster sampling. The study subjects comprised 208 children, with 90 boys and 118 girls. Data analysis used correlation coefficients with the Kolmogorov–Smirnov normality test. Result: The probability value of the correlation between BMI and anterior crowding was 0.24, which meets the significance level (α <0.05). The probability value between the BMI and EH was 0.102, which is not significant (α >0.05). Conclusion: There is a correlation between BMI and anterior crowding, but there is no correlation between BMI and EH.
