Comparison of postoperative pain following single-visit and two-visit root canal therapy in controlled diabetic patients with irreversible pulpitis: A randomized control trial

AIM: The aim of this study was to evaluate and compare the prevalence of postoperative pain after single- and two-visit endodontic therapy in controlled Type 2 diabetic and nondiabetic individuals in multirooted teeth with irreversible pulpitis. MATERIALS AND METHODS: Ninety patients with irreversible pulpitis (30 controlled diabetics and 60 nondiabetics), between 18 and 60 years were included in the study. After obtaining initial pain scores, patients were randomly allocated to single-visit or two-visit root canal treatment (RCT) groups to receive standardized treatment. After the first visit, patients were given visual analog scale form to mark pain intensity at 1 h, 6 h, 12 h, 24 h, 48 h, 72 h, and 1 week. The compiled data collected were statistically analyzed using 20 SPSS software. RESULTS: In both groups, for patients undergoing single-visit and multi-visit RCT, pain intensity was highest on 1(st) day of treatment and dropped afterward. A comparison of pain between single-visit and two-visit patients revealed no significant difference in pain scores for the respective time intervals. Intergroup comparison between controlled diabetics and nondiabetics showed no significant difference in pain reported between both groups. CONCLUSION: According to the results of this study, being diabetic or nondiabetic, no difference in pain perception was seen between single- and multiple-visit endodontics suggesting that single-visit as well as two-visit endodontic treatment can be done in controlled diabetic patients.
