Abstract

Saliva plays a critical role in homeostasis of oral cavity, since creates the balance in oral cavity ecosystem. Respecting very important roles and various functions of saliva in oral cavity, this study aimed to compare the salivary pH in smoking and non-smoking healthy individuals in referees to oral medicine department of Tabriz dental school.

Mann u-Whitney test revealed that the difference between salivary pH between smoking patients and healthy individuals was significant (P<0.05). The difference in age mean between two groups was not significant (P>0.05). Conclusions: Based on the findings of this study, the salivary pH level in smoking patients was lower than healthy non-smoking individuals.
