Background: Periodontal disease is a group of inflammatory disorders, the pathophysiology of which is related to tooth accumulated microbial plaque and the host response to those accumulations. The development of periodontal disease has been thought to be associated with several restricted members of oral anaerobic species such as Spirochetes, Porphyromonas etc. Aims & Objectives: The aim of the present study was to compare the effect of oral irrigation with Ozonated water, 0.2% Chlorhexidine and 10% Povidone iodine in patients with chronic periodontitis. Materials and Methods: A randomized clinical trial was performed. A total of 30 patients of both sexes in age group 30-50 yrs suffering from generalized chronic periodontitis were selected for the study. They were divided into three groups (ten patients in each) A, B, C in which they were irrigated with ozonated water, 0.2% Chlorhexidine (CHX) and Povidone iodine respectively. The use of all three types of irrigation was randomized. Results: A higher percentage of Gingival index (72%), Plaque index (57.69%) and Pocket probing depth reduction (39.68%) was observed in four weeks using ozonated water irrigation as compared to Chlorhexidine and Povidone iodine. The percentile reduction of spirochetes (30.50%) using ozonated water was appreciable as compared to Chlorhexidine (t-stat value 0.14) and Povidone iodine(t-stat value 0.16). P value of 0.05 or less was considered statistically significant.  Conclusion: Local ozone application can serve as potent atraumatic, antimicrobial agent to treat periodontal disease non surgically both for home care and professional practice. It may also serve as good tool during supportive periodontal therapy.
