The scores of PI, GI, PPD, and CAL from baseline to 6-week follow-up within both the test and control sites were noted to be statistically significant ( < 0.0001). The CFU showed a significant reduction ( = 0.0229) within the test site at varying time intervals. The change in the mean PI score from baseline to 6-week time interval between the test and control site was noted to be statistically significant ( = 0.0039). The local application of BITC chips effectively reduced the PI, GI, PPD, and CFU, subsequently with the gain in CAL, and improved the tissue integrity and thereby oral hygiene.

Procalcitonin (ProCT) is an emerging inflammatory biomarker in bacterial infections. Few studies have reported raising salivary ProCT in periodontitis patients. Hence, the study aims to analyze and correlate the changes in saliva and serum ProCT in periodontitis patients before and after nonsurgical periodontal therapy. We have included 15 chronic periodontitis patients of mean age 41.8 ± 6.82 years who satisfy the inclusion criteria in the study. After saliva and serum collection, clinical parameters such as plaque index, gingival index, gingival bleeding index, probing pocket depth, and clinical attachment were recorded, and scaling and root debridement were performed. Reevaluation was done at 1- and 3-month interval. ProCT was estimated using the enzyme-linked immunosorbent assay. Salivary ProCT was significantly greater than its serum counterpart at baseline and 1 month after periodontal therapy (0.20 vs. 0.26, 0.13 vs. 0.14 ng/ml respectively). We noticed a significant reduction in salivary as well as serum ProCT (35% and 46%, respectively) 1 month after scaling and root debridement. A significant moderate positiv
