Abstract
  • Previous studies indicate that hypertension is correlated with diminished sensitivity to experimental pain. This prospective observational study was designed to test the hypothesis that resting arterial blood pressure is inversely correlated to decreased postoperative pain following endodontic therapy. Written informed consent was obtained from patients seeking treatment for their teeth diagnosed with pulpal necrosis and periradicular periodontitis. Preoperative blood pressure was recorded and subjects rated their pre-operative pain intensity using a 100mm visual analog scale. Standardized non-surgical root canal therapy was initiated. Subjects were given a pain diary in which they recorded their post-operative pain and analgesic intake over 7 days. After controlling for pre-operative pain, a significant correlation was noted between Day 1 postoperative pain and preoperative systolic blood pressure (p<.03) and preoperative pulse pressure (p<.005). This study provides support for a functional interaction between the cardiovascular and pain regulatory systems.
