ABSTRACT
OBJECTIVES: The study aimed to determine the relationship between the eruption timing of permanent teeth and anthropological assessments (height and weight) in children from Chennai, India.
MATERIALS AND METHODS: A cross-sectional study was designed, and 12650 children were selected using a multistage random sampling method. The clinical eruption status of all permanent teeth was evaluated using a novel grading system, and correlational analysis determined the relationship between height/weight and tooth eruption age.
RESULTS: The study found statistically significant associations between tooth eruption ages and both height and weight. While the correlation for height was weak and non-significant (r = -0.023 to 0.151, including zero), the correlation for weight was more pronounced (r = 0.044 to 0.519).
CONCLUSION: The study suggests that both height and weight are significantly associated with tooth eruption ages, but weight has a stronger and more consistent influence. Individuals with obesity tend to experience delayed tooth eruption.
