Abstract
Introduction
The purpose of this study was to evaluate the effect of the piezoelectric device on
intraoperative hemorrhage control during surgery and the quality of life of patients
after endodontic microsurgery.
Methods
A total of 40 patients were randomly divided into the piezo group (n = 20) and the control group (n = 20). In the piezo group, after flap reflection, bone cutting, granulation tissue
removal, and root-end resection were performed using the piezoelectric surgical device
and surgical carbide burs, and curettes were used in the control group. The quality
of life of patients was evaluated daily for 1 week postsurgery for limitations of
oral and general functions, pain, and other symptoms. Limitation of functions and
other symptoms were recorded by a modified version of the patient’s perception questionnaire
using a 5-point Likert scale for mouth opening, chewing, speaking, sleeping, daily
routine, missed work, swelling, nausea, and bad taste/breath, and the visual analog
scale was adopted for pain. 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. For variables related to function and symptoms other than
pain and analgesics taken, the Fisher exact test was used. For the assessment of pain
between the 2 groups, the Mann-Whitney U test was used.
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).
Conclusions
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.
