Abstract
BACKGROUND: The traditional method of diagnosing periodontitis includes the assessment of clinical parameters and radiographic aids to evaluate the periodontal tissue destruction. Saliva has the potential to be used as the diagnostic fluid for oral disease. This study aimed at comparing the quantitative levels of alkaline phosphatase (ALP) in saliva and serum before and after scaling and root planing in patients with chronic generalized periodontitis. MATERIALS AND METHODS: A total number of 50 participants (40 with chronic generalized periodontitis and 10 periodontally healthy volunteers) of 30-50 years were included in the study. Clinical parameters such as simplified oral hygiene index (OHI-S), gingival index, probing depth, and clinical attachment loss (CAL) were measured, and then, saliva and blood sample collection was done and analyzed for ALP levels by spectrometry. The clinical parameters along with saliva and serum ALP levels were reevaluated after 30 days following Phase I periodontal therapy. The results were statistically analyzed using paired t-test and one-way ANOVA. RESULTS: The saliva and serum ALP levels were significantly increased in patients with chronic generalized periodontitis with an increase in clinical parameters such as OHI-S, gingival index, probing depth, and CAL when compared with periodontally healthy individuals. The saliva and serum ALP levels were significantly decreased following Phase I periodontal, therapy along with improvement in clinical parameters. CONCLUSION: With the limitations of the present study, it could be concluded that ALP levels in saliva can be used for the diagnosis of active phase of periodontal disease and also for evaluation of the treatment outcomes following Phase I periodontal therapy.
