Effect of piezoelectric device on intraoperative hemostasis and quality of life after endodontic microsurgery in maxillary molars: A randomized controlled trial.

[INTRODUCTION] This study compared the effect of piezoelectric device and conventional burs on the quality of life (QoL) and intraoperative hemostasis after endodontic microsurgery in maxillary molars.

[MATERIALS AND METHODS] Thirty patients were divided randomly into the control group (bur) and the test group (piezoelectric). QoL was estimated using a modified version of the patient's perception questionnaire (PPQ) up to 7postoperative days and oral health impact profile-14 (OHIP-14) at baseline, till 7 days, 6 months, and 12 months. A visual analog scale was used for pain assessment. Statistical analysis applied was Fisher's exact/Chi-square test, Mann-Whitney test, Friedman test, and Wilcoxon signed rank test.

[RESULTS] Significantly less swelling and interruption of meals from 1 to 3 day, less pain on 1 and 2 day, less analgesic consumption on 2 day, and less difficulty in relaxation from 3 to 5 day were observed in the test group. A significantly higher adverse impact was noted in meal interruption on 1 day and difficulty relaxing on 2 day in the control group. Significant and similar improvement in OHIP summary score in both groups was observed at 6 months and 12 months from baseline. Significantly better hemostasis and perforation were found in the test group with odds of 5.5 and 6.4, respectively.

[CONCLUSIONS] Piezoelectric surgery improved patients' QoL postsurgery as assessed by PPQ and OHIP-14, along with better intraoperative hemostasis.
