Objectives: The purpose of this study was to compare the pH and buffering capacity of saliva in subjects with caries and subjects without caries. Material and methods: The present study included 40 children in the age group of 12 years, who were divided in two groups - 20 subjects with caries and 20 subjects without caries. The stimulated salivary samples were collected from both the groups and analyzed for pH, buffering capacity. The data was statistically analyzed using student's 't' test {unpaired}. Pearsons correlation test was used to find the correlation between buffering capacity and salivary pH in subjects with caries and subjects without caries. Results: In the present study it was found that the salivary pH and buffering capacity were slightly reduced in subject with caries as compared to subject without caries. However the difference was not found to be statistically significant Further when the relation between pH and buffering capacity was analyzed, it was found that salivary pH was inversely correlated to buffering capacity in both the subjects with caries and without caries. Conclusion: Within the limitation of this study, we can conclude that, the physicochemical properties of saliva play a major role in the development of dental caries.
