This clinical study was undertaken to determine whether endodontic therapy affected the cardiovascular physiology of 30 patients with pulpal pathosis, as evidenced by changes in blood pressure or heart rate, or by arrhythmia. Regardless of the type of pathosis, mean systolic and diastolic blood pressures and mean heart rates were similar during the various procedures at each appointment or at successive appointments. However, these parameters were significantly higher in patients treated for pulpitis or symptomatic necrosis than in patients treated for asymptomatic necrosis. This was attributed to the presence and severity of pain. Seven of the 30 patients had episodes of arrhythmia that could not be related to a specific procedure, appointment, or type of pulpal pathosis. On the basis of these findings, it appears that nonsurgical endodontic therapy has no effect on the cardiovascular system of patients with no known history of cardiovascular disease. However, the type of pulpal pathosis may produce statistically significant cardiovascular changes.
