Abstract

Objectives: To compare the development of white spot lesions (WSLs) during fixed orthodontic therapy among a conventional three-step bonding system, a self-etching primer bonding system, and a one-step adhesive bonding system.

Materials and methods: Seventy-five patients were randomly allocated into three groups (group 1, conventional bonding system, n = 25; group 2, self-etch primer, n = 25; group 3, primer mixed with adhesive composite, n = 25). Quantitative light-induced fluorescence (QLF) was used to assess WSL parameters. Images were captured and then analyzed before treatment and at 2 months and 4 months after bond up. Lesion area (pixels), mean fluorescence loss (ΔF), and the number of newly developed WSLs were compared within and among the three groups. The significance level was P ≤ .05.

Results: The mean increase in lesion area was 31.3 ± 2.8 pixels, 38.4 ± 4.3 pixels, and 119.5 ± 5.3 pixels for groups 1, 2, and 3, respectively (P ≤ .001). For ΔF, the loss was 3.3% ± 0.3%, 4.4% ± 0.2%, and 6.6% ± 0.2% for groups 1, 2, and 3, respectively. These changes were significantly different (P ≤ .01 to P ≤ .001). The incidence of newly developed lesions was 9.5 WSLs in group 1, 10 WSLs in group 2, and 15.9 WSLs in group 3.

Conclusions: The lack of primer contributed to the development of a larger number of and more severe WSLs.

三种正畸粘接系统在白斑病变发展中的比较：一项随机临床试验。

目的：比较传统三步粘接系统、自蚀刻底漆粘接系统和一步粘接系统在固定正畸治疗过程中白斑病变（WSL）的发展情况。材料和方法：75例患者被随机分为三组（第一组，常规粘接系统，n=25；第二组，自蚀刻底漆，n=25，第三组，底漆与粘合剂复合物混合，n=25）。定量光诱导荧光（QLF）用于评估WSL参数。在治疗前以及结合后2个月和4个月采集图像并进行分析。比较三组内和三组间的病变面积（像素）、平均荧光损失（ΔF）和新发展的WSL数量。显著性水平为P≤.05。结果：第1、2和3组病变面积的平均增加分别为31.3±2.8像素、38.4±4.3像素和119.5±5.3像素（P≤.001）。ΔF的损失分别为3.3%±0.3%、4.4%±0.2%和6.6%±0.2%。这些变化有显著差异（P≤.01至P≤.001）。新发病变的发生率在第1组为9.5个WSL，第2组为10个，第3组为15.9个WSL。结论：缺乏引物导致了更多、更严重的WSL的发生。
