Abstract：Objective:To investigate the clinical efficacy of three oxygen therapy in the treatment of chronic periodontitis Methods:80 patients were randomly divided into four groups (group A,B,C,D).After subgingival scaling/root planning,teeth in group A,B,C,D were irrigated by 20.0 μg·m1-1Ozonated water,42.2 μg·mlt Ozonated water,0.12％ chlorhexidine (CHX) and 0.9％ NS.Parameters included gingival index (GI),plaque index (PLI),bleeding index (BI),probing depth (PD) and clinical attachment level (CAL) were measured after subgin.The gingival index of the A group and the depth of the diagnosis were 0.65± 0.67,1.70± 0.73,which were significantly better than those of chlorhexidine acetate group and saline group,and the difference was statistically significant (P＜0.05) Bleeding index (BI) of group A was 1.40± 1.05 and curative effect was worse than the group of 0.12％ CHX,and the difference had a significant effect (P＜0.05).PLI and CAL of group A were 0.70± 0.73,0.95± 0.69 and curative effect was better than the group of 0.12％ CHX,but there were no statistically significant differences after treatment (P ＞0.05).However different concentrations of Ozonated water had an adjunct treatment to the chronic periodontitis,there were no statistically significant differences after treatment (P＞ 0.05).Conclusion:Subgingival irrigation with Ozonated water combined with SRP could help improve the gingival inflammation status in treating Chronic periodontitis.
