Effectiveness of ozone in the management of chronic periodontitis: A clinico-microbiological study

Aim: To evaluate the efficacy of ozonated water with NSPT compared with scaling and root planing (SRP) alone in treating chronic periodontitis. Settings and Design: The current study is a double-masked, randomized clinical trial. Methods and Material: A total of 30 patients aged 25 to 55 years were divided randomly into two groups having probing pocket depths of ≥ 5 mm. Full mouth SRP were performed in group 1 followed by additional sub-gingival irrigation of ozonated water in group 2. Assessment of plaque index (PI), gingival index (GI), probing pocket depth (PPD), and clinical attachment levels (CAL) was performed at baseline and six months. Microbiologic assessment with real-time polymerase chain reaction was performed for Dialister pneumosintes and Micromonas micros by collecting plaque samples. Statistical Analysis Used: The data were subjected to statistical analysis with IBM SPSS Software version 21. The results were presented under the headings of various parameters considered for this study. Results: The results revealed that there was a reduction in PI, GI, PD, CAL, and microbiologic parameters in both groups following SRP; the results were more significant in group 2 treated by sub-gingival irrigation with ozonated water, when compared with SRP alone in group 1. Also, it was noted that there was a statistically significant reduction of M. micros compared to D. pneumosintes in the ozone-treated group. Conclusions: The Subgingival irrigation of ozonated water in conjunction with SRP has beneficial effects in treating patients with chronic periodontitis.
