Postoperative Pain and Healing in Teeth Treated With GentleWave or EndoActivator

Patients with painful molars will be randomly assigned to 2 different groups: GentleWave and EndoActivator. The root canals will be completed using identical protocols except in the mode of delivery and activation of irrigation (using either the GentleWave or EndoActivator). Postoperative pain and pain pill consumption will be measured for the 4 days following their root canal using a Visual Analog Scale and Pain Pill Log, respectively. The alternative hypothesis is that patients undergoing treatment using the GentleWave will experience less pain postoperatively and will consume fewer pain pills. A 12-month follow up with exam and radiographs will be completed to evaluate healing.
