Abstract
Objective: The aim of this study was to compare the vital signs as mean arterial pressure and heart rate of patients undergoing two different temporomandibular joint (TMJ) arthrocentesis techniques.
 Methods: Thirty patients received TMJ arthrocentesis with either double puncture arthrocentesis (DPA) or single puncture arthrocentesis (SPA). Blood pressure and heart rate were assessed preoperatively, during the application of local anesthesia, and at needle insertion into the joint cavity, the 5th and 10th minute of the procedure, and the end of the procedure.
