Abstract

INTRODUCTION

The aim of this two-arm parallel trial was to evaluate enamel demineralization in fixed orthodontic treatment using an indirect bonding technique in comparison to a direct bonding technique by the quantitative light-induced fluorescence (QLF) method.

DESIGN, SETTINGS AND PARTICIPANTS: Fifty-six patients who needed fixed orthodontic treatment were randomly separated into either the direct bonding group or the indirect bonding group. The presence and extent of lesions on the buccal surfaces of all teeth, except the molar teeth, were assessed. The percentage of fluorescence loss (ΔF and ΔFmax), the degree of demineralization (ΔQ) and lesion area (WS area) were determined using the system's software. The data were analysed with the Wilcoxon signed-rank and Mann-Whitney U-tests (P < 0.05).

INTERVENTIONS

Treatment with a direct bonding or an indirect bonding technique.

RESULTS

This study was completed with 25 patients in the indirect bonding group (12 females, 13 males; mean age: 15.42 ± 1.71 years) and 26 patients in the direct bonding group (12 females, 14 males; mean age: 14.73 ± 1.65 years). In the indirect bonding technique, a few teeth (especially mandibular left canine: 50.45 ± 93.48; 95% confidence interval: -12.35 and 113.26) were found to develop significant white spot lesion (WSL) formation (P < 0.05). However, the number of teeth with demineralization was higher in the direct bonding group (P < 0.05).

CONCLUSION

The bonding procedures used in the indirect bonding technique contribute to reducing the degree of WSL formation. Further, the use of flowable composite adhesives in this bonding process is more effective at reducing the appearance of WSLs than in cases where conventional composite adhesives are used.

LIMITATIONS

The limitation of our trial may be the small sample size and the short follow-up time for the patients.

HARMS

No harms were detected during the study.

PROTOCOL

The protocol was not published before trial commencement.

摘要

简介

本双臂平行试验旨在通过定量光致荧光（QLF）法评估间接粘接技术与直接粘接技术在固定正畸治疗中釉质脱矿的情况。

设计、环境和参与者：56 名需要固定正畸治疗的患者被随机分为直接粘接组或间接粘接组。评估所有牙齿（除磨牙外）颊面的病变存在和程度。使用系统软件确定荧光损失百分比（ΔF 和 ΔFmax）、脱矿程度（ΔQ）和病变面积（WS 面积）。采用 Wilcoxon 符号秩和检验和 Mann-Whitney U 检验（P<0.05）进行数据分析。

干预措施

直接粘接或间接粘接技术治疗。

结果

本研究完成于 25 例间接粘接组患者（12 名女性，13 名男性；平均年龄：15.42±1.71 岁）和 26 例直接粘接组患者（12 名女性，14 名男性；平均年龄：14.73±1.65 岁）。在间接粘接技术中，少数牙齿（尤其是下颌左侧尖牙：50.45±93.48；95%置信区间：-12.35 和 113.26）发现明显的白垩斑（WSL）形成（P<0.05）。然而，直接粘接组中发生脱矿的牙齿数量更高（P<0.05）。
