Epidemiological Study on the Dental Caries Prevalence of School children in Taiwan

Objective: Fluoride has been an effective tool to prevent dental caries but efforts have been on to establish optimal level of fluoride in drinking water in different communities. The present study seeks to establish the safe and acceptable concentration of fluoride in drinking water which would lead to maximum caries protection with least amount of clinically observable dental fluorosis. Study Design: 30 villages from 2 districts of Haryana were classified according to differing levels of fluoride in the drinking water. 3007 school children(1558 males & 1449 female)] were examined and the DMFT score was related to the level of fluoride in drinking water. Results: The caries prevalence was maximum (48.02%) in the area having 0.50 ppm fluoride in drinking water. The children from area having the 1.13 ppm fluoride level had the least caries prevalence i.e. 28.07%. Conclusion: The results of the present study did not suggest any additional anticaries benefit beyond 1.13ppm fluoride level. The present investigation showed that the optimal fluoride levels for drinking water for our conditions were near 1.13ppm (1-1.2 ppm) as there was maximum caries protection with least amount of esthetically objectionable fluorosis at that level.

Objective: To describe the experience and prevalence of dental caries in schoolchildren aged 6–12 years belonging to agricultural manual worker households. Material and Methods: A comparative cross-sectional study was conducted in two groups of schoolchildren: One considered “children of agricultural worker migrant parents” (n = 157) and the other “children of agricultural worker non-migrant parents” (n = 164). Epidemiological indices for dental caries were calculated for primary (dmft) and permanent (DMFT) dentitions, and compared in terms of age, sex, and the Simplified Oral Hygiene Index (SOHI). Two binary logistic regression models for caries prevalence in primary and permanent dentitions were generated in Stata. Results: For primary dentition, we observed the following dmft index: Non-migrants = 1.73 ± 2.18 vs. migrants = 1.68 ± 2.14. Additionally, we recorded the following caries prevalence: Non-migrants = 59.1% vs. migrants = 51.3%. For permanent dentition, we observed the following DMFT index: Non-migrants = 0.32 ± 0.81 vs. migrants = 0.29 ± 0.95. Further, we recorded the following caries prevalence: Non-migrants = 17.6% vs. migrants = 12.8%. No differences were observed for either dentition (p > 0.05) in caries indices and their components or in caries prevalence. When both caries indices (dmft and DMFT) were combined, the non-migrant group had a higher level of caries experience than the migrant group (p < 0.05). No relationship (p > 0.05) with migrant status was observed in either multivariate models of caries prevalence. However, age did exhibit an association (p < 0.05) with caries. Only the plaque component of SOHI was associated (p < 0.05) with caries in permanent dentition. Conclusions: Although over half of school children from agricultural manual worker households had caries in either or both dentitions and a considerable proportion were untreated lesions, the prevalence levels were somewhat lower than other reports from Mexico in similar age groups. No statistically significant differences were found in caries experience or prevalence in either dentition between non-migrant and migrant groups.

Fear Survey Schedule

ABSTRACT Objective: To assess the level of fear of dental procedures among 6-12 year school children and correlate the prevalence of dental caries with their dental fears scores. Materials and Methods: The study sample of 444 school children, comprising of 224 girls and 220 boys in the age group of 6-12 years old from a private English medium school were selected. Each student was asked to independently complete a Children′s Fear Survey Schedule - Dental Subscale (CFSS-DS) questionnaire. Children having a score of ≥ 38 were included in the ′′dental fear′′ group while those scoring <38 were placed in the ′′without dental fear′′ group. All dental examinations were performed in the classroom. Results: Fear scores were highest for ′′Injections,′′ (3.76 ± 0.68) ′′Choking,′′ (3.48 ± 0.63) and ′′Dentist drilling′′ (2.88 ± 0.69). The overall mean score of CFSS-DS in our study was 37.0 ± 8.89, mean score of DMFT and DMFS were 0.58 ± 0.74 and 0.73 ± 1.09, respectively. Mean score of deft and defs were 4.40 ± 2.34 and 7.28 ± 5.49, respectively. Conclusion: The study showed the prevalence of dental fear in 6-12 year old children and there was no statistically significant co-relation between the level of dental fear and dental caries in these children.
