Incidence of pot operative pain following singe visit endodontic therapy in single and multirooted teeth

Aim of the study: The incidence of post-operative pain was compared following single-visit canal treatment in single- and multi-rooted teeth, with and without periapical radiolucency. The article also reviews the issues of postoperative pain and healing , following single-visit and multi-visit endodontic therapy. Single-visit endodontic therapy (SVE) was performed in 50 single-rooted teeth and 60 multiple-rooted teeth Materials and Method: Single-visit endodontic therapy (SVE) was performed in 50 single-rooted teeth and 60 multiple-rooted teeth. The subjects were divided as follows: Group I –Single-rooted teeth with periapical radiolucency (n=25); Group II–Single-rooted teeth without periapical radiolucency (n=25); Group III–Multiple-rooted teeth with periapical radiolucency (n=30); and Group IV–Multiple-rooted teeth without periapical radiolucency (n=30). Assessment of postoperative pain was done at 24hrs, 3 days and 1 week using a self report questionnaire.The data was analyzed using non-parametric Kruskal –Wallis test. Results: No statistically significant difference was observed in postoperative pain following SVE between the single-rooted and multiple-rooted teeth groups at 24hrs, 3 days and 1 week. The presence or absence of periapical radiolucency had no significant influence on the incidence of reported post-operative pain following SVE. Conclusion: There was no difference in incidence of pain in single rooted teeth and multi-rooted teeth with and without periapical radiolucencies following SVE. Thus, incidence of post-operative pain does not seem to be a valid comparison criterion between single- and multiple-visit endodontic therapies. Also, the literature suggests similar success rates with single-visit and multiple-visit root canal treatment
