Background: Orthodontic ligatures have an important role during edgewise bracket sliding along a continuous arch wire. The present study was conducted to compare elastic ligation vs stainless steel ligation in root canal treated teeth. Materials & Methods: The present study was conducted on 90 patients requiring orthodontic treatment of both genders. Patients were randomly divided into 2 groups of 45 each. In group I patients, elastic ligation was used and in group II patients, stainless steel ligation was used. In both groups, bleeding index and probing periodontal depth was measured. Results: The mean probing periodontal depth in group I was 1.8 and in group II was 1.4. The difference was non- significant (P> 0.05). The mean bleeding score in group I was 2.4 and in group II was 2.6. The difference was non- significant (P> 0.05). Conclusion: Authors found both elastic and stainless steel ligation equally effective. There was non- significant effect on bleeding score and probing periodontal depth. Key words: Elastic, Stainless steel, ligation.
