Nutritional Status is Associated with Permanent Tooth Eruption in a Group of Brazilian School Children

摘要

The present study aimed to investigate the association between nutritional status with delayed tooth eruption (DTE). Oral examination was performed in schoolchildren (8-11years old), and DTE was defined by absence of dental gingival emergence or when primary tooth was still present in the oral cavity after the expected time. BMI z-score of each child were collected and nutritional status was defined. Chi-square test and binary logistic regression adjusted by age and gender were performed. Odds ratio (OR) and 95% Confidence Interval (95% CI) were calculated. The established alpha was 5%. Among 353 included children, 247 were classified as eutrophic, 16 as underweight, 64 as overweight, and 26 as obese. Underweight was associated as a risk factor to DTE (P=.014; OR=3.5; 95% CI=1.3-9.8), and underweight girls had more chance to present DTE than eutrophic girls (P=.048; OR=4.4; 95% CI=1.1-17.2) in chi square test. In logistic regression, underweight was associated as a risk factor to DTE (OR=4.21; CI 95%=1.42-12.43; P=.009). Underweight children have a higher risk of DTE in permanents.
