Background: Saliva is a complex biological fluid which maintains hemostasis of oral cavity and keeps oral mucosa healthy. Change in resting whole mouth salivary flow rate (SFR) plays a significant role in pathogenesis of various oral conditions. Factors such as tobacco chewing, smoking may affect SFR as well as oral and dental health. Aim: Schirmer's test is used routinely by ophthalmologists to measure tear film wetness. These strips have been previously used for sialometry. So primary purpose of this study is to assess the SFR in tobacco chewers, smokers. Objectives: To correlate the salivary flow rate among tobacco chewers and smokers and to assess the rate of xerostomia among tobacco chewers and smokers. Methodology: 90 male individuals was divided into 3 groups -tobacco chewing group, smoking group and healthy individuals. SFR was carried out based on length and color change of strip on wetting. The results obtained will be analyzed by Mann-Whitney test and Chisquare test. Statistical analysis: To analyze the salivary flow rate among 3 groupsKruskal-Wallis testwas performed and to analyze the xerostomia and mean salivary flow between chewers and smokers Mann-Whitney testwas performed. Results: 53% of smokers showed xerostomia when compared to chewers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
