Objective: this study evaluated hemodynamic variations of normotensive and hypertensive patients undergoing dental extraction under local anesthesia with 3% prilocaine with 0.03 UI/ml felypressin. Material and Methods: Forty-nine patients from the Department of Surgery and Maxillo-facial Traumatology ambulatory were evaluated. Thirty were normotensive and 19 hypertensive; they presented initial systolic blood pressure lower than 160 mmHg and diastolic blood pressure lower than 100 mmHg, besides being under medical supervision. Patients underwent molar or premolar extraction, typically deployed with maximum degree of mobility 2, according to Miller’s classification. The parameters evaluated were systolic and diastolic blood pressures and heart rate, using an automatic digital pulse device, in the following periods: T1 - Initial (5 min before the beginning of surgery, with the patient seated); T2 - post-anesthesia (after 2 min of anesthetic administration); T3 - trans-operative (every 5 min after the measurement T2 to complete 20 min, totaling 4 trans-operative measurements); T4 after surgery (5 min after removal of the surgical field). Results: statistical analysis showed for the parameters systolic blood pressure (P = 0.959) and diastolic blood pressure (P = 0.754), no statistically
