Abstract (2. Language): 
Introduction-Recent role of chemotherapeutic agents in form of local delivery system as an adjunct to mechanical therapy suggest improvement in periodontal health. The aim of present study was to evaluate clinical and microbiological effectiveness of locally delivered 0.5% azithromycin gel as an adjunct to scaling and root planing in managing chronic periodontitis patient. Material and Methods-This was randomized control trial using split mouth study design. A total of 40 sites from 20 patients, who had pocket depth more than 5 mm and diagnosed as chronic periodontitis, were selected for the study. These were randomly categorized in two treatment groups: scaling and root planning only (control group) and scaling and root planning plus 0.5% azithromycin gel (test group). Clinical parameters such as gingival index, probing pocket depth and clinical attachment level were recorded at baseline, 6 weeks and 12 weeks at selected sites for both the groups. Result & observations-Overall parameters improved from baseline in both test and control group. Mean pocket depth reduction from baseline to 12 weeks was 4.1500±0.6708 and 4.350±0.489 in test and control respectively, the difference being statistically significant at p<0.001.Mean clinical attachment level gain from baseline to 12 weeks, the difference being statistically significant at p<0.05. All microbiologic categories showed significant improvement in both groups, with greater improvement in the test group. Conclusion Based on the results it was concluded that locally delivered Azithromycin might be a valuable adjunct to scaling and root planing in the treatment of chronic periodontitis.
