Efficacy of subgingival ozone irrigation as an adjunct to non-surgical periodontal therapy in management of chronic periodontitis

: Aim of the study was to determine the adjunctive role of subgingival irrigating solutions i.e., ozonated water, 0.2% chlorhexidine and 5% Povidine Iodine in Phase-I periodontal treatment and to compare the efficacy of subgingival irrigating medicament being used in studyRandomized controlled clinical trial was performed on 45 patients that were divided into three groups, the ozone group (Group A), chlorhexidine group (Group B) and povidone iodine group (Group C). Patients underwent scaling and root planing (SRP) in a single visit followed by irrigation with ozone water, chlorhexidine and povidone iodine in. The clinical parameters of Gingival Index (GI), Plaque Index (PI), probing pocket depth (PPD), Clinical Attachment Level (CAL) and modified sulcular bleeding index were measured at baseline, at 1 month and at the end of 3 months.All clinical parameters like plaque index, gingival index, probing pocket depth, clinical attachment level and modified sulcus bleeding index at baseline, 1 month and after 3 months. Ozone group was found to be superior than chlorhexidine followed by Povidone Iodine in terms of reduction of Plaque Index. However, intergroup comparison for other parameters did showed difference but it was not statistically significant.: It can be concluded that use of ozone can serve as beneficial irrigating solution to treat chronic periodontitis for home care and professional practice. More studies with a larger sample size may be used to evaluate the potential of these irrigating agents.
