POLYMERASE CHAIN REACTION TO EVALUATE THE EFFICACY OF SILICA DIOXIDE COLLOIDAL SOLUTIONS IN THE TREATMENT OF CHRONIC PERIODONTITIS: A CASE CONTROL STUDY.

The objective of this study was to compare the efficacy of supportive periodontal therapy [i.e. scaling and rooth planing (SRP)] alone versus a chemical silica dioxide (SiO2) colloidal solution (SDCS) device used in association with SRP in the treatment of chronic periodontitis in adult patients. A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients had previously received any surgical or non-surgical periodontal therapy and had radiographic evidence of moderate bone loss. Two non-adjacent sites in separate quadrants were selected in each patient to monitorize treatment efficacy (split mouth design). Clinical pocket depth (PD) and microbial analysis (MA) were analyzed at baseline and on 15th day. SPSS program and paired simple statistic t-test were used to detect significant differences. Total bacteria loading, Tannerella forsitia and Treponema denticola loading were statistically reduced when SiO2 was locally delivered. SDCS gel is an adjuvant therapy which should be added to SRP in the management of moderate-to-severe chronic periodontitis.
