Estimation of salivary pH and viability of on chewing of Tulsi leaves in children.

Background: The current concepts of dental caries focus on cariogenic bacteria such as Streptococcus mutans fermenting carbohydrates to form organic acids, which cause a drop in pH, resulting in demineralization of the tooth surface. Studies show that Tulsi has broad-spectrum antimicrobial activity. Hence, this study aimed at estimating the change in salivary pH and viability of S.
