Background: Dental caries is a localized, progressive destructive, largely irreversible microbial based disease of multifactorial nature; these factors include (host, microbes and food) they influence differently on the initiation and progression of dental caries. The aims of the study: was to evaluate the effect of smoking on salivary flow rate, secretory immunoglobulin (SIgA) level and viable count of mutans streptococci (M.S) bacteria in oral cavity and their relation to dental caries experience. Material and method: The samples were collected from 80 male students ranging in ages from 18-22 years old. Where they divided in to two groups, 40 non-smokers (control group) and 40 smokers (study group). Unstimulated salivary samples were collected. Salivary flow rate was estimated and viable count (CFU/ml) of mutans streptococci was determined. The diagnosis and recording of dental caries were done according to WHO, 1987 criteria and the level of SIgA was determined by ELISA. Result: the result revealed that the salivary flow rate and SIgA level were lower in smoker group than non-smoker, while the means value of dental caries experience Decay, Missing and Filling tooth (DMFT) and (CFU/ml)of M.S were higher in oral cavity of smoker group than non-smoker group. Conclusion: the smoking has negative effect on salivary flow rate, SIgA and increase the viable bacterial count of M.S and dental caries in smoker patients
