Introduction Periodontitis is an infammatory condition caused by a specifc group of microorganisms. It affects the supporting structures of the oral cavity leading to increased pocket depth, clinical attach- ment loss, recession, mobility, bone loss, furcation involvement, pathologic migration and tooth loss [1-7]. Even though the pri- mary etiology of the disease is dental plaque, the disease is aggra- vated by variety of risk factors including smoking, stress, genetic factors, systemic diseases and hormonal distress[8-16]. Scaling and root planing (SRP) therapy is considered as the gold standard for periodontal disease [17]. However, SRP is subjected to certain restrictions, such as the failure to insert deeper peri- odontal pockets, bifurcations and the failure to eliminate micro- organisms because of their tissue invading nature [18-20]. To overcome this, variety of adjuncts including irrigants, chemical plaque controlling agents, vitamin supplements, systemic and lo- Abstract Background: Mechanical plaque control is the frst line of management of chronic periodontitis. In recent years, a variety of adjuncts including irrigants, chemical plaque controlling agents, vitamin supplements, systemic and local antibiotics, local drug delivery, herbal extracts, probiotics and LASER are gaining importance. Aim: The aim of the study was to assess the effcacy of ozonated water and 10 percent povidone iodine as sub gingival irrigant in the management of chronic periodontitis. Materials and Methods: The present randomized clinical trial was carried out from June 2020 to December 2020 among 40 chronic periodontitis patients who reported to the Department of Periodontics, Saveetha Dental College and Hospitals, Chennai, India. Participants were assigned to two groups [Group 1 (10% povidone iodine), Group 2 (ozonated water)]. Scal- ing and root planing was done for all the participants and then the pocket was irrigated with respective irrigant. The clinical pa- rameters including Loe and Silness Gingival Index (GI), Pocket Depth (PD), Silness and Loe Plaque index (PI) were recorded at baseline and after 1 week. The data was analyzed using Statistical Package for Social Sciences (SPSS Software, Version 23.0). Unpaired t-test was done to compare the mean values of gingival index, plaque index and pocket depth between the groups. Results: In group 1, the mean gingival index was reduced from 2.89±0.03 to 2.20±0.03. In group 2, the mean gingival index was reduced from 2.92±0.02 to 1.48±0.01. When plaque index was compared between both the groups, in group 1, the mean plaque index was reduced from 2.87±0.02 to 2.40±0.03. In group 2, the mean plaque index was reduced from 2.86±0.05 to 1.42±0.01. When probing depth was compared between both the groups, in group 1, the mean plaque index was reduced from 5±0.02 to 3±0.03. In group 2, the mean plaque index was reduced from 4±0.05 to 2±0.01. The difference in all the clinical parameters between both the groups was found to be statistically signifcant (p=0.000). Conclusion: Signifcant improvement in gingival index, plaque index and pocket depth suggests that subgingival ozonated water irrigation could be an effective adjunct to scaling and root planing in the management of chronic periodontitis.
