ABSTRACT
The present cross-sectional study was conducted to assess and compare the prevalence of dental caries of 229 deaf adolescents in a special senior high school and to identify factors related to dental caries, with a match group of 196 healthy adolescents in a normal senior high school, in Jiangsu province of East China. In this study the prevalence of dental caries was 55.9%, Decayed, Missing and Filled Teeth (DMFT) index in deaf students was 1.40±1.89; in healthy students was 13.8% and 1.36±1.72, respectively. Relatively lower proportion of awareness on dental health knowledge and lower proper practice of dental health behavior have been observed among deaf students compared with the control group. Multiple logistic regressions showed that the risk factors of dental caries in deaf students involved high frequency of consuming dessert and carbonated beverage. Poor oral health, lack of oral health knowledge and proper oral health practice could be found in deaf students. The dental treatment for the two groups was urgently needed. The dental health education concerning dietary behavior and prevention program to the deaf students and their parents should be reinforced; the supervision of oral health behavior for deaf and healthy students needs to be strengthened.

BACKGROUND: In epidemiological studies, tuberculosis (TB) appears intimately with vitamin D insufficiency whereas its relationship with vitamin D receptor (VDR) polymorphism caused by radical difference remains unspecified. This study aimed to investigate the relationship between vitamin D genetic polymorphism and tuberculosis in Han ethnic group. METHODS: Meta-analysis was adopted in the synthetic quantitative analysis of documents home and abroad on the relationship between vitamin D genetic polymorphisms and tuberculosis, which were openly published during June 2000 to January 2010. Random effect model and fixed effect model analyses were used to calculate the incorporated odds ratio (OR) based on the heterogeneity test data. RESULTS: A total of 6 eligible studies were included in this analysis. The FokI-ff genotype showed a significant marginal association (Fixed effect model: OR 1.91, 95%CI 1.44-2.52; Random effect model: OR 1.91, 95%CI 0.94-3.88), yet TaqI polymorphisms was not significantly related to TB. CONCLUSION: The interaction between FoKI genotype polymorphism and TB observed demonstrates that vitamin D deficiency might exist as a risk factor during the development of TB in Han ethnic group and more evidences needed to validate the conclusion.
