Effectiveness of Different Concentrations of Chlorhexidine and Metronidazole Gels in the Management of Gingivitis: A Randomized Clinical Trial

Background: Management of gingivitis is commonly done by the removal of etiological agents by Periodontist. However, use of topical applications of antibiotic combinations has been shown to improve the treatment outcome. Various drugs alone or in combination have been used. So this study was conducted to determine the effect of different concentrations of combination drugs on gingivitis.Material & Methods:100 patients of gingivitis were divided into two groups of 50 each – Group-A and Group-B. After scaling and root planing, Group-A patients were made to apply Metronidazole 1% and Chlorhexidine 0.25% for period of 12 weeks while as Group-B patients applied Metronidazole 1.5% and Chlorhexidine 0.50% for 12 weeks. Baseline scores of gingival index and bleeding index were recorded followed by readings at 4 and 12 weeks.Results:Results showed that there was a significant improvement in gingivitis and bleeding on probing at 4 and 12 weeks after local application of Metronidazole and Chlorhexidine gel in both the groups. However there were no statistically significant differences between two groups.Conclusions:Topical application of Metronidazole and Chlorhexidine gel as an adjunct to scaling and root planing is an effective treatment modality for the management of gingivitis and the concentrations of the combination do not have any significant effect on the treatment.
