Abstract

Background: Numerous factors contribute to variation in tooth size. This is broadly described as genetic, epigenetic, and environmental factors. A strong genetic contribution has been shown, but environmental factors may also play a role. Aim: The aim of this study was to determine the relationship between nutritional status and tooth crown size. Design: An observational cross-sectional survey was conducted among 100 school-going children of 6–9 years. The value obtained was plotted on age- and gender-specific percentile curves chart given by the Centers for Disease Control and Prevention; individuals were categorized based on body mass index criteria. The participants were examined for the mesiodistal width of primary second molar and permanent first molar by three different observers using a Vernier Caliper. Data obtained were statistically analyzed. Results: total of 45, 40, and 15 belonged to underweight, normal, and overweight category, respectively. The tooth size of primary molar between healthy, overweight, and underweight children was 9.87 ± 0.23, 9.47 ± 0.48, and 9.61 ± 0.7, respectively, and for permanent molar between healthy, overweight, and underweight children was 10.63 ± 0.2, 10.56 ± 0.5, and 10.57 ± 0.6, respectively. Conclusion: The correlation between tooth crown size with an exogenous chronic stressor, i.e., malnutrition, was found to be nonsignificant when compared with the healthy individuals. The findings indicate that nutritional status does not significantly influence the determination of tooth size in humans.
