Introduction: Several studies have found smoking a significant risk factor for periodontitis. Smoking alters salivary pH in order to improve nicotine absorption. Resting salivary pH estimate a range of 5.5 to 7.9, with the higher pH exhibited upon increased salivary flow. Imbalance of pH might constitute a local factor for periodontal disease activation. Objective: The purpose of this study was to determine the association of salivary pH with periodontal disease status in smokers and non-smokers. Materials and methods: 20 individuals were included in the study. 10 smokers and 10 non-smoker. Periodontal status was assed and the whole mouth unstimulated saliva was collected, measured and pH estimated extra orally. Means of pH were compared statically using SPSS 11.5. Results and conclusions: The difference between mean pH of smokers and non-smokers was statistically significant. Different levels of periodontal disease were found on both groups. The results of this study suggest that pH alteration may contribute to periodontal disease in smoker patients however it is not the main aspect of the pathogenesis.
