Abstract

Background: Surgical removal of impacted mandibular third molars is a routine procedure in dental practice. However, this intervention may inevitably affect the surrounding bone and soft tissues, leading to common postoperative complications such as swelling, pain, and trismus. Piezoelectric instruments, which utilize microvibrations to cut bone, are considered to offer several advantages over conventional rotary instruments, including reduced morbidity and improved patient comfort during and after surgery. Objective: To compare the intraoperative experiences and postoperative satisfaction of patients undergoing surgical removal of impacted mandibular third molars using piezoelectric versus rotary instruments. Materials and Methods: A split-mouth randomized clinical trial was conducted involving 22 patients requiring bilateral surgical removal of impacted mandibular third molars. Each patient underwent one surgery using piezoelectric instruments and the contralateral surgery using conventional rotary instruments. Intraoperative experience and postoperative satisfaction were assessed using a self-administered questionnaire based on a 5-point Likert scale. Postoperative satisfaction was evaluated on postoperative day 5. Results: Patient satisfaction following surgery was significantly higher in the piezoelectric group (p < 0.05).  However, no statistically significant difference was observed in intraoperative experience scores between the two techniques. Conclusion: The use of piezoelectric instruments in third molar surgery enhances postoperative patient satisfaction, as evidenced by improvements in mastication, speech, sleep quality, and daily physical activities, thereby contributing to an overall improvement in quality of life during the postoperative recovery period.
