Postoperative Pain After Root Canal Preparation Using Different Engine-driven Systems

Not Applicable

Completed

• Conditions: Asymptomatic Molar Teeth With Periapical Lesions

• Registration Number: NCT04454814
• Lead Sponsor: Ege University

Brief Summary

A hundred twenty patients who had an asymptomatic mandibular molar teeth with periapical lesion were included. For each patient, teeth were prepared with Reciproc Blue or Protaper Universal instruments. Each tooth was obturated with gutta-percha and resin-based sealer using single cone technique for mesial roots and for distal roots single cone and cold lateral compaction technique. Root canal treatment was performed in a single visit. Postoperative pain was assessed as no, mild, moderate, or severe at 6, 12, 24, 48, 72 hours and 7 days after obturation.

Detailed Description

The aim of this study was to compare the effect of root canal preparation techniques on the occurrence and intensity of postoperative pain in patients with asymptomatic mandibular molar teeth with periapical lesions.A hundred twenty patients who had an asymptomatic mandibular molar teeth with periapical lesion were included. For each patient, teeth were prepared with Reciproc Blue or Protaper Universal instruments. Each tooth was obturated with gutta-percha and resin-based sealer using single cone technique for mesial roots and for distal roots single cone and cold lateral compaction technique. Root canal treatment was performed in a single visit. Postoperative pain was assessed as no, mild, moderate, or severe at 6, 12, 24, 48, 72 hours and 7 days after obturation.For the comparison of pain scores between the tested instrumentation systems, the Mann Whitney test was used. Differences between postoperative pain intencity for each instrumentation technique, at different time intervals, were assessed by the Friedman test. For the association of pain and an analgesic intake with gender, the chi-square test was performed. For the association of pain with age and an analgesic intake were calculated using Mann Whitney test. A P value \< .05 or less was considered significant.

Primary Outcome Measures

Name	Time	Method
The incidence of postoperative pain	6-hour to 7-day	Postoperative pain after 6, 12, 24, 48, 72 hours and 7 days after obturation was measured using a modified 4-grade visual analogue scale (VAS) ranging from 1(no pain), 2(mild pain), 3 (moderate pain/pain relieved by analgesics), to (4) severe pain.
