Objective. To evaluate if nutritional status is associated with caries and gingivitis in Brazilian schoolchildren. Material and methods. Children of both genders, age ranging from 8 to 11 years old, were included in this study. Caries was diagnosed using ICDAS (International System for Detection and Assessment of Carious Lesions) and gingivitis was diagnosed using the Community Periodontal Index. The nutritional status of each child was defined by BMI Z-score calculation. Data on oral health behavior and dietary habit were collected through parent’s questionnaires. Parametric analyzes were performed to compare the groups. The established alpha was 5%. Results. The sample consisted of 353 schoolchildren: 16 underweight children, 247 eutrophic children, 64 overweight children, and 26 were obese children. Overweight, Obese and Overweight + Obese children presented less cavitated caries lesion than Eutrophic children ( P < .05). Gingivitis was not associated with nutritional status ( P > .05). Conclusion. Caries was associated with overweight and obesity in Brazilian schoolchildren.

Vitamin D is a liposoluble secosteroid essential for the maintenance of the body's mineral balance. 1 Vitamin D participates in the enamel and dentin calcification 2-7 and the correct immune response to oral microbial infections. 2-7 Vitamin D acts by binding an intra-cellular receptor, the vitamin D receptor (VDR). 8 VDR is a nuclear transcription

The present study aimed to investigate the association between nutritional status with delayed tooth eruption (DTE). Oral examination was performed in schoolchildren (8-11 years 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.

The aim of this study was to evaluate the distribution profile of childhood bruxism using Geographic Information System in the city of Alfenas, in southwest Brazil. The study included schoolchildren of both sex attending public schools in the city of Alfenas - Minas Gerais, Brazil. During clinical examination, the presence or absence of bruxism for each child was recorded. For statistical analysis, Chi-square test and t test was used to compare sex and age distribution according to the groups, with an established alpha of 5%. A Geographic Information System was used to perform the geoprocessing procedures. The home addresses were geocoded on a map to apply the kernel density estimator. The final sample includes 353 children, in which 44 presented signs of bruxism. Age and gender were not associated with bruxism (p>0.05). The spatial analysis of the distribution of childhood bruxism in the city of Alfenas indicated an occurrence of a hotspot. In conclusion, there is an intra­urban differentials in childhood bruxism in the city.
