Dental Caries in Primary and Permanent Molars in 7-8-Year Old School Children Evaluated with Caries Assessment Spectrum and Treatment (CAST) Index from Bangalore North
Journal Title: International Journal of Contemporary Medical Research - Year 2016, Vol 3, Issue 8
Abstract
Introduction: Caries is a common biofilm-mediated chronic disease that affects all ages. So, the study was done to evaluate caries in primary and first permanent molars of 7-8-year-old children by the Caries Assessment Spectrum and Treatment (CAST) index and to find whether there was any correlation between the caries stages in such teeth. Materials and methods: The study covered 100 7-8-year-old children from randomly selected schools in the North Bangalore. The prevalence of CAST categories was evaluated with regard to the first and second primary, and first permanent, molars. The Spearman’s rank correlation coefficient was used to explore the correlation of the distribution of CAST codes among the evaluated teeth. This parameter is compared using Kruskalwallis non parametric test. The level of statistical significance was established at p < 0.1. The intra-examiner reliability was determined by the unweighted kappa coefficient. Results: With regard to deciduous teeth, 70% subjects showed a dentin cavity (code 5) as the most serious caries stage. In 1st and 2nd primary molars, caries was most often recorded at the stage of cavitated dentin lesion. With regard to the permanent molars, enamel lesions were most prevalent (code 3) and most lesions were scored at the non-cavitation level. Teeth with pulpal involvement, sepsis and extracted due to caries were found to be more prevalent in first, and then in second primary molars. The strong correlation was found in teeth present in maxilla and mandible. The ‘r ‘ value was 0.217 and 0.109 in maxilla and mandible (p < 0.1), respectively. For neighbouring primary and permanent molars ‘r’ values were lower than 0.1, which meant a weak correlation. Conclusion: A strong correlation was found between the status of teeth from the maxilla and mandible. The study proved the usefulness of the CAST index in epidemiological surveys.
