INTRODUCTION
The aim of the present study was to compare the tendency of mandibular incisor rotation relapse after conventional circumferential supracrestal fiberotomy (CSF) with Er,Cr:YSGG laser-aided CSF.
METHODS
In this three-arm parallel study, the patients with one lower incisor rotation greater than 30 degrees before treatment were selected. The patients were randomly assigned to three groups in a 1:1:1 ratio. Rotational relapse tendency was measured on a digitized model one month after arch wire removal. Probing depth, clinical crown height and pain levels were also measured.
RESULTS
A total of 46 patients were recruited. Relapse tendency in conventional CSF and laser-aided CSF groups were 5.09±1.59° and 4.87±2.08°, respectively, and significantly lower than 11.28±2.93° in the control group (P<0.001). Relapse tendency was not different between the conventional CSF and laser CSF groups. Probing depth, clinical crown height, and experienced pain levels exhibited negligible differences.
CONCLUSIONS
Er,Cr:YSGG laser-aided CSF in one month was as effective in reducing rotational relapse tendency of mandibular incisor teeth as conventional CSF.
引言
本研究的目的是比较传统环行龈上纤维切断术（CSF）与铒铬：钇钪镓石榴石（Er,Cr:YSGG）激光辅助CSF术后下颌切牙旋转复发的趋势。
方法
在这项三臂平行研究中，选择治疗前一颗下切牙旋转大于30度的患者。患者按1:1:1的比例随机分为三组。在拆除弓丝后1个月，在数字化模型上测量旋转复发趋势。还测量了探诊深度、临床冠高度和疼痛程度。
结果
共招募了46名患者。传统CSF组和激光辅助CSF组的复发趋势分别为5.09±1.59°和4.87±2.08°，显著低于对照组的11.28±2.93°（P<0.001）。传统CSF组和激光CSF组之间的复发趋势没有差异。探诊深度、临床冠高度和经历的疼痛程度显示出可忽略不计的差异。
结论
铒铬：钇钪镓石榴石（Er,Cr:YSGG）激光辅助CSF在1个月内减少下颌切牙旋转复发趋势方面与传统CSF同样有效。
