Periodontal health status of heavy and light smokers and its correlation with salivary superoxide dismutase enzyme (A comparative study)
Main Article Content
Abstract
Materials and Methods: The study sample consisted of 75 male, with age ranged from 35 to 50 years. Clinically, the periodontal parameters used in this study were Plaque index (PLI). Gingival index (GI), probing pocket depth (PPD), Bleeding on probing (BOP) and clinical attachment level (CAL), unstimulated saliva sample were collected from all subjects and the levels of superoxide dismutase enzyme was analyzed for each group , and correlate the mean of salivary enzyme levels with the clinical periodontal parameters.
Results: Highly significant differences in PLI between (non smokers/heavy smokers) and (light smokers/heavy smokers).On the other hand no significant difference in gingival index between groups.
There were a high association between severity of smoking & probing pocket depth and there is association between severity of smoking and clinical attachment loss. There were a significant difference in the level of salivary superoxide dismutase enzyme between the (non smokers/light smokers) groups & between (heavy smokers/light smokers) &there were highly significant differences between (non smokers/heavy smokers) groups. There is no correlation between the activities of the salivary superoxide dismutase enzyme and the clinical periodontal parameters except in SOD with (BOP score 0 and PPD score 1&score 3) in heavy smokers group.
Conclusions: Superoxide dismutase enzyme can be used as biomarker for estimating the level of oxidative stress on smoking habits.
