Abstract
목적: 치과의사의 사용 만족도 비교를 통해 두 가지 피에조 엔진의 성능을 비교평가 하고자 한다.
연구 재료 및 방법: 본 연구에서는 두 가지의 피에조 엔진을 평가하였다:TRAUS XUS10 (Saeshin), PIEZOSURGERY touch (Mectron). 20명의 치과의사가 11개 평가항목에 답하였고, 평가결과는 Likert의 5점 척도를 적용하여 수치화하였다. 핸드피스 소음평가는 10초 동안 5회 측정하여 최고소음을 비교하였다. 핸드피스 발열평가는 세 부위에서 3분동안의 발열량을 측정하였다.
결과: 평가항목 중 ‘주수펌프 모터의 소음’에서 TRAUS XUS10이 PIEZOSURGERY touch보다 유의하게 만족도가 높았다. 반면, ‘기능key의 만족도’와 ‘핸드피스 발열정도’는 PIEZOSURGERY touch가 더 우수했다. 소음 최대값은 TRAUS XUS10이 56.6 dB, PIEZOSURGERY touch는 56.0 dB였다. 두 기기 모두 3분 작동 후 41°C 미만의 열을 발생시킴으로써 안전기준을 만족하였다.
결론: TRAUS XUS10는 ‘기능 key’ 및 ‘핸드피스 발열정도’에서 약간의 개선을 한다면 그 외 대부분의 평가항목에서는 PIEZOSURGERY touch과 견줄만한 성능을 보인다.
Purpose: The aim of this study is to compare the performance of two piezoelectric engine systems by surveying satisfaction from dental clinicians.
Materials and Methods: Two piezoelectric systems were evaluated: TRAUS XUS10 (Saeshin), PIEZOSURGERY touch (Mectron). For this study, 20 dentists responded to the 11 questionnaires in which 5 point Likert-type scale was used. The two devices were operated for 10 seconds and measured 5 times to compare the maximum noise values. In heat emission test, the handpiece was operated for 3 minutes and heat was measured at three positions each.
Results: TRAUS XUS10 had higher satisfaction level on motor noise (P < 0.05). About function key and handpiece heat generation, PIEZOSURGERY touch showed higher satisfaction (P < 0.05) than TRAUS XUS10. The maximum noise level for each of the devices was confirmed to be 56.6 dB for the TRAUS XUS10 and 56.0 dB for PIEZOSURGERY touch. The two piezoelectric engines satisfied the safety standards with an operation temperature below 41°C after having been operated for 3 minutes.
Conclusion: Except for the function key and handpiece heat emission, TRAUS XUS10 has comparable performance with PIEZOSURGERY touch.
