Evaluation of Pain in Single and Multi-Rooted Teeth Treated in Single Visit Endodontic Therapy.

Abstract

Background: 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 & Methods: Single-visit endodontic therapy (SVE) was performed in 50 singlerooted 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)
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 multirooted 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.
