An Epidemiological Study on Dental Caries Prevalence of Permanent Teeth in School Children : Examination by Quantification Types I and II

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 evaluate the prevalence of dental caries in patients with cleft lip and/or palate and their cleft-free sibling controls. Methods: The two subject groups (patient and control) comprised 106 participants. The former group consisted of 53 patients with cleft lip and/or palate, aged 12 to 29 years, who visited the Oral and Maxillofacial Surgery Hospital at Damascus University of Syria. The control group consisted of the patients’ siblings who had no clefts, and they were sex matched to the patient group. Dental caries were examined clinically and were reported using the decayed, missing, and filled permanent teeth (DMFT) index. The DMFT scores were compared between the two groups. Results: The author found an overall association of dental caries with the presence of cleft lip and/or palate (odds ratio = 2.52; 95% confidence interval = 1.389–4.574; p < .05). The DMFT index scores were proportionally higher in patients with cleft lip and/or palate compared with the control group (p < .001). Conclusion: Subjects with cleft lip and palate are susceptible to dental caries independently of socioeconomic status.

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.

Previous studies on the global burden of caries primarily focused on simple descriptive statistics. We aimed to characterize the burden, trends, and inequalities of untreated caries of permanent and deciduous teeth from 1990 to 2019 at the global, regional, and national levels through an array of analytic approaches. Estimates of caries burden were extracted from the Global Burden of Disease Study 2019. Decomposition analysis was performed to examine the contribution of demographic and epidemiologic factors to the evolving number of prevalent caries cases. In portfolio analysis, the caries epidemiologic profile of each country was categorized by terciles of age-standardized prevalence in 2019 and average annual percentage change from 1990 to 2019. Sociodemographic attribution analysis was performed to reveal the scale of inequality in burden of caries. Age-standardized prevalence of caries in permanent and deciduous teeth decreased 3.6% (95% uncertainty interval, 2.6% to 4.5%) and 3.0% (1.3% to 4.9%), respectively. Population growth was the key driver of the changes in the number of caries cases, especially in sub-Saharan Africa (percentage contribution: 126.6%, permanent teeth; 103.0%, deciduous teeth). Caries prevalence in the permanent dentition was lower in more developed countries, whereas a reverse trend was noted in the deciduous dentition, except for the highest sociodemographic quintile where caries prevalence was the lowest. Globally, 64.6 million (95% CI, 64.4 to 64.9 million) and 62.9 million (62.8 to 63.1 million) prevalent cases of caries in permanent and deciduous teeth were attributable to sociodemographic inequality in 2019. This amounted to 3.2% (3.2% to 3.2%) and 12.1% (12.1% to 12.1%) of the global number of prevalent cases of caries in permanent and deciduous teeth. Burden of dental caries remains a global public health challenge. A systemwide reform of the global oral health care system is needed to tackle the causes of the burden and inequality of dental caries.

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.
