RESUMO
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.
RESUMO
BACKGROUND & AIM: To investigate the association between the genetic polymorphisms FokI (rs2228570) and BglI (rs739837) in vitamin D receptor (VDR) with dental caries and gingivitis susceptibility. DESIGN: This study included 353 Brazilian children (8 to 11 years old). Dental caries was assessed using ICDAS (International System for Detection and Assessment of Carious Lesions) and gingival bleeding using Community Periodontal Index (CPI). The presence of visible biofilm was also evaluated. DNA was extracted from saliva, and real-time PCR was used to evaluate genetic polymorphisms in VDR: rs2228570 (FokI, A>G/Met>Thr) and rs739837 (BglI, G>T). Dental caries was evaluated as a continuous data (mean and standard deviation-SD) and was also categorized (ICDAS0 versus ICDAS1-6 or ICDAS1-2 versus ICDAS3-6). Gingivitis was categorized in with and without. One-way ANOVA was used for comparisons of caries among genotypes. Chi-square test, logistic regression, and haplotype analysis were performed (P < .05). RESULTS: Biofilm was associated with dental caries susceptibility and gingivitis (P < .05). The mean distribution of the caries lesions and cavitated caries lesions among FokI and BgII genotypes were not statistically significant (P > .05). Genotype distributions among caries groups (in the two different cut-offs) and among gingivitis and non-gingivitis groups were not statistically significant (P > .05). CONCLUSION: The polymorphisms FokI and BglI in VDR were not associated with dental caries or gingivitis.
