Background: Sometimes, a combination of mechanical and chemical treatment provides good recovery such as metronidazole (MTZ) and hyaluronic acid (HA) topically that have recently been recognized as an adjunct therapeutic measure for periodontitis. Aims and Objectives: The objective is to estimate and compare the potential benefits of the effect of MTZ and HA gels on the clinical periodontal parameters. Materials and Methods: Chronic periodontitis patients were volunteered to partake in this research. They classified into three groups; 10 patients received root surface debridement (RSD) and 0.2% HA gel was additionally applied subgingival in test sites as the first group, the second group (10 patients) received RSD and MTZ gel was also added subgingival in test sites, and the last group consisting of 10-patient management with RSD alone. At the first visit, plaque index, gingival index, and periodontal pocket depth (PI, GI, and PPD) were recorded subsequently, and this represents 1st record which was done before periodontal treatment, while the 2nd record for indices was taken after 7 days. Results: Intragroup analysis of all the clinical periodontal parameters showed high significant (HS) results between baseline and 1 week at P < 0.01. In addition, on intergroup analysis, the results were significant at a second visit for GI and HS for PPD and not significant for PI. Conclusion: Local applications of MTZ and (0.2%) HA gels as an auxiliary to conventional periodontal therapy have a useful impact on clinical periodontal parameter during 7 days in chronic periodontitis patient.
