Objectives: To assess the dental caries experience, salivary flow rate, buffering capacity, Streptococcus mutans and Lactobacilli counts in 13 year old Belgaum schoolchildren, to determine the association between dental caries experience and the parameters and to use the data for creating caries risk profile. Material & Methods: 159, schoolchildren 13-year old, were selected from 4 schools in Belgaum city. DMFT was recorded using WHO criteria (1997). Paraffin stimulated saliva was collected for 5 minutes. Salivary flow rate, buffering capacity and salivary counts of Streptococcus mutans and Lactobacilli were determined. Students't' test, chi square test and Pearson's correlation coefficient were used to statistically analyze the data. Results: 44.02% were caries free. The mean DMFT value recorded for the sample was 1.34. Mean flow rate of stimulated saliva was 1.160.6m1/min. 61.63% had high buffering capacity and 38.37% had intermediate buffering capacity. The percentage of Streptococcus mutans and Lactobacilli carriers were 80.50% and 36.47% respectively. The salivary flow rate, buffering capacity and Lactobacilli count did not differ significantly with respect to the different caries experience, while a highly significant (p < O.OOl) difference was observed between the different DMFT values and Streptococcus mutans count. Conclusion: The data collected helped to create risk profile of the children and helped for planning and implementing a tailor-made caries preventive program.
