Effect of Piezo on Intraoperative Hemorrhage Control in Endodontic Microsurgical Procedure: An Original Research

Abstract

Introduction: The purpose of this study was to evaluate the effect of the piezoelectric device on intraoperative hemorrhage control during endodontic microsurgical procedure.

Material and Methods: A total of 40 patients were randomly divided into the piezo group (n = 20) and the control group (n = 20). The quality of life of patients was evaluated daily for 1 week postsurgery for limitations of oral and general functions, pain, and other symptoms. Hemorrhage control during surgery was independently assessed by the surgeon and 2 blinded observers and recorded as 0 (no hemorrhage control), 1 (intermittent control), and 2 (complete control). The chi-square test was used to assess hemorrhage control.

Results: For parameters of quality of life, the piezo group showed significantly less swelling on the first, second, and third days and pain on the first and second days compared with the control group (P < .05). Analgesics taken were also significantly less in the piezo group (P < .05). In the piezo group, complete hemorrhage control was achieved in 10 patients, and in the control group, it was achieved only in 1 patient (P < .05).

Conclusion: Piezoelectric surgery resulted in improved quality of life of patients in the first week postsurgery with lower levels of pain and swelling as well as the number of analgesics taken and better hemorrhage control during surgery.
