Objectives. To determine the complete range of carious conditions and furthermore to compare the risk factors and patterns of dental caries amongst schoolchildren aged 12 and 15 years in Bhubaneswar. Material and Methods. Cross-sectional descriptive survey was performed among 800 schoolchildren to assess the dental caries status by Caries Assessment Spectrum and Treatment (CAST) scoring. Chi-square, parametric t-test, one-way ANOVA with post hoc Bonferroni and stepwise multiple linear regression were utilized for statistical analysis. Results. Study population comprised of 476 (59.5%) boys and 324 (40.5%) girls, of which 356 (44.5%) and 444 (55.5%) represented the 12- and 15-years age group respectively. Prevalence of dental caries was 60.6% (Mean 0.38+0.545). Younger age group children presented a significant (p<0.05) lower caries prevalence (54.8%) as against 65.3% in 15 years children. Majority, 189 (23.6%) revealed distinct visual change in enamel (code 3). Acuteness of disease constructed on maximum CAST score for each subject showed that teeth with morbidity (28.5%) is higher followed by reversible pre-morbidity (23.6%) and serious morbidity (6.5%). Predominantly first molars were generally influenced. Significant interpreters in plunging order for DMFT were frequency of cleaning teeth and sweet score. Conclusions. A creative instrument named CAST index describes full continuum of dental caries. Its utilization in epidemiological studies is exceptionally encouraging as it is less tedious and more cost effective. It can possibly be a useful tool for planning caries control programs in both individual and community levels.
