This study was set out to investigate and analyze the prevalence of dental caries in preschool children in Shanghe County in Shandong Province, China, and provide new insights into potential prevention and treatment strategies. Methods Based on the random sampling method, we performed dental examinations of children aged 2 to 6 years in kindergartens of Shanghe County. The prevalence of caries, the average number of decayed teeth per capita as well as the constituent rates of decayed, missing and filled teeth were determined retrospectively. SPSS software was used for data analysis. Results Dental caries were found in 1088 out of 2052 children from 56 kindergartens. The total number of decayed teeth was 4487 with a prevalence of 53.02%. The average number of decayed teeth per capita was 2.187, and the filling rate was 0.29%. There was no statistical difference in the prevalence of caries between boys and girls though there were significant differences between different age groups. The prevalence of decayed teeth as well as the mean number of decayed teeth infected per capita increased with age. In addition, urban children had a higher prevalence than those from rural areas （P 〈0.01）. Conclusions The prevalence of decayed caries among kindergarten children in Shanghe County was high, suggesting that more emphasis should be put on improving oral health education with priority given to prevention. Further efforts should be made to increase the decayed caries filling rate.展开更多

The objective of this study was to analyze the relationship between blood glucose control and oral diseases in a population of diabetics followed at the “Centre Anti Diabétique d’Abidjan” (CADA). The dental condition of the diabetics included in this cross-sectional study was assessed by the DMF index, periodontal condition by the CPITN and oral hygiene by the OHIS index. Diabetes data were extracted from CADA patient medical records. Blood glucose control has been defined by an average of the blood glucose values of the last 3 months less than or equal to 1.26 g/l. Regression models were constructed to estimate the risk of diabetes imbalance adjusted for all characteristics collected. The sample of 356 diabetics consisted of 53.7% women with an average age of 55.6 years (range: 12 - 85 years). The average DMF index was 7.9 (Std: 6.6) with an estimated prevalence of caries of 77.0%, that of periodontitis of 53.1%. The proportion of subjects with good glycemic control was estimated at 41.3%. The characteristics associated with glycemic control were: dry mouth (p = 0.005), type of diabetes treatment (p < 0.00014) and duration of diabetes (p = 0.039) and periodontal status assessed with the CPITN (p = 0.014). The results of this study confirmed the link between periodontitis and glycemic control of diabetes described in the literature but didn’t find significant association between dental caries and diabetes.展开更多
