Key result
Preoperative systolic blood pressure and pulse pressure were significantly correlated with Day 1 postoperative pain following endodontic therapy (p<.03 and p<.005, respectively).
Why the study?
Hypertension has been correlated with diminished sensitivity to experimental pain, motivating an investigation into whether resting arterial blood pressure inversely correlates with postoperative pain following endodontic therapy.
Is resting arterial blood pressure inversely correlated with postoperative pain following endodontic therapy in patients with pulpal necrosis and periradicular periodontitis?
Observational
Is resting arterial blood pressure inversely correlated with postoperative pain following endodontic therapy in patients with pulpal necrosis and periradicular periodontitis?
Higher preoperative systolic and pulse pressures are significantly correlated with decreased Day 1 postoperative pain following endodontic therapy, supporting a functional interaction between cardiovascular and pain regulatory systems.

Preoperative BP associated with less post-endodontic pain; supports cardiovascular-pain interaction but leaves open need for prospective confirmation.
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.

James Wayne King (2019) conducted an observational in Pulpal necrosis and periradicular periodontitis. Preoperative resting arterial blood pressure was evaluated on Day 1 postoperative pain (p=<.03 for systolic, <.005 for pulse pressure). Preoperative systolic blood pressure and pulse pressure were significantly correlated with Day 1 postoperative pain following endodontic therapy (p<.03 and p<.005, respectively).
