Background: Ocimum sanctum (tulsi) and Azadirachta indica (neem) leaves has been suggested as an antibacterial mouthwash for youngsters. Despite the fact that these herbal plants are having anti-cariogenic property, there are no research on their ability to reverse the cariogenic impacts of other diets.Aim: The purpose of this study was to see if chewing of O. sanctum and A. indica leaves following a cariogenic stimulus caused salivary pH reversal.Methods and Materials: Participants were randomly assigned to one of two groups: Category A using A. indica plant leaves or Category B using O. sanctum leaves. Salivary samples were obtained at 5 minute, 30 minute, and 60 minute intervals after chewing out the herb leaves and completely expectorating to assess the salivary pH. A digital pH metre (HI 2211 pH/ORP Meter, Rhode Island, USA) was used to measure salivary pH, which was adjusted with standard sample solution of pH 4.0 and 7.0.Results: The salivary pH of both category A and category B children fell significantly after eating chocolate at 5 and 30 minutes and gradually restored to initial level after about 60 minutes.
