Brief summary

Introduction: This study aimed to compare the intensity of postoperative pain after single-visit root canal treatment of symptomatic or asymptomatic teeth following occlusal reduction. Methods: A total of 140 symptomatic or asymptomatic patients in need of root canal therapy were registered in this prospective, single-center, single-blind, randomized clinical trial. For all patients, root canal treatment was carried out in a single visit, and the teeth were restored using composite resin. The teeth were randomly allocated into two equal groups according to whether occlusal reduction was done or not. The patients' pain were assessed using a 0-3 verbal rate scale 1, 3, and 7 days following root canal treatment. The pain incidence and intensity were compared using the chi-square and Fisher's exact tests.

Detailed description

Root canal treatments is usually associated with post-operative pain and this is a bothersome situation for both patient and practitioner. Due to this reason number of researches focus on the factors that may relief patients pain. Occlusal reduction is one of the factors that means the chewing surface of the teeth are cut off and no longer in contact.Despite the large number of studies on this subject, no consensus has been reached. Decoupling group standardization and arriving at a more consistent conclusion were the goals of this research. The aim of this research is to evaluate the impact of occlusal reduction on postoperative pain in both symptomatic and asymptomatic molar teeth.

Interventions

Occlusal reduction is a procedure that applied patients for different aims. One of these aims is pain relief after endodontic treatment and there are some studies about this topic however, there is no consensus about it. This discrepency could be related to differences of the inclusion criteria for this reason this study aimed to get a reliable result.

MeasureTime frameDescription
Effect of occlusal reduction on pain relieffrom enrollment to the end each patient called for a week to understand their pain levels and each of them called after 1st, 3th, 7th days treatment.This study was primarily aim to understand the effect of occlusal reduction on pain relief after root canal treatment of irriversible pulpitis. After root canal treatment patients were called to estimate their pain levels. A 0-3 rate verbal rating scale was used for this aim. 0: no discomfort or pain 1. mild pain (not requiring analgesic medication) 2. moderate pain (requiring analgesic medication) 3. severe pain (interfering with physical activity and minimally responsive to analgesics)
