Laser Activation in Reducing Pain During and After Root Canal Treatment for Painful Lower Molar Teeth.

CSI College of Dental Sciences and Research, Madurai50 enrolled

Overview

Effectiveness of lasers in reducing pain during and after root canal treatment for mandibular molar teeth affected with acute irreversible pulpitis.

AIM : To assess the intraoperative and postoperative pain incidence for single visit root canal treatment for mandibular molar teeth with acute irreversible pulpitis following laser activation. MATERIALS AND METHODS: The study will account the patients who are referred to the Department of Endodontics,both male and female patients,with pain due to acute irreversible pulpitis from carious mandibular first and second molar teeth requiring root canal treatment. Subjects of age 13 to 70 years who met the inclusion criteria and responded positively to cold test will be included in the study. Single visit root canal treatment with 2.5 mL of 2% lignocaine containing 1:80,000 adrenaline for an inferior alveolar block injection will be administered for each individual. After achieving anesthesia, patients who exhibit pain following access opening will be subjected to diode laser application on the pulp canal orifices. With regard to intraoperative pain, pre laser and post laser intraoperative pain incidence will be recorded. Once when the intraoperative pain incidence is reduced, patients will be reassessed for the need of additional anesthesia. If fully anesthetised, root canal procedure will be completed. Preoperative, intraoperative( before and laser application) pulse rate will also be measured. The levels of preoperative and post-operative pain at 24 hrs and 48 hrs for each patient will be recorded using a 10-point visual analog scale (VAS).
