Aim: This study evaluates the role of low-level laser emission/photobiomodulation (LE/P) in quantitative measurements of root resorption (QRR). The application of LE/P performed after each orthodontic activation with four types of treatment intervention (TI) on the root resorption (RR) after fixed orthodontic treatment (FOT) of the upper arch with ectopic eye tooth/teeth [EET] was investigated. Materials and Methods: Thirty-two orthodontic patients scheduled for FOT were selected and assigned to the four groups. These were LE/P + Self ligating bracket (SLB), LE/P + Conventional bracket (CB), non-photobiomodulation (non-LE/P) + SLB and non-LE/P + CB. Standard management stages of FOT were followed in the maxilla. Each patient received a single application of LE/P labially/buccally and palatally, a total of five different points were used during each activation or appointment. The main outcome measure was QRR in maxillary anteriors before and after FOT, assessed via cone-beam computed tomography (CBCT) using 3D OnDemand software. Results: Insignificant QRR was found between before and after FOT in SLB, CLB, and LE/P, non-LE/P groups (p > 0.05). QRR in the SLB vs. CB and LE/P vs. non-LE/P group was significantly different in 11, 13, and 23 (p < 0.05). QRR in the LE/P + SLB group (p < 0.05) was significantly different in 11, 13, and 23 than that in the other groups. The most severe QRR was found on 13 (0.88 ± 0.28 mm and 0.87 ± 0.27 mm) and 23 (1.19 ± 0.14 mm and 1.16±0.13 mm) in the CB and non-LE/P group (p < 0.001). LE/P + SLB showed a highly significant superior outcome (p < 0.001) in relation to non-LE/P + CB, the QRR of 23 were 0.813 ± 0.114 mm and 1.156 ± 0.166 mm, respectively. Conclusion: Significantly higher amounts of QRR were found in EET patients after FOT treated with the CB, non-LE/P, and non-LE/P + CB system and warrant further investigation to explore potential specific causes.
本研究评估低强度激光发射/光生物调节（LE/P）在牙根吸收定量测量（QRR）中的作用。研究了在上颌弓异位尖牙/多颗尖牙[EET]进行固定正畸治疗（FOT）后，每次正畸加力后应用LE/P对牙根吸收（RR）的影响，并设置了四种治疗干预（TI）。材料与方法：选取32例计划进行FOT的正畸患者，分为四组，分别为LE/P + 自锁托槽（SLB）组、LE/P + 传统托槽（CB）组、非光生物调节（非LE/P）+ SLB组和非LE/P + CB组。上颌遵循FOT的标准治疗阶段。每位患者在唇侧/颊侧和腭侧接受一次LE/P照射，每次加力或就诊时共使用五个不同的点。主要观察指标为FOT前后上颌前牙的QRR，通过锥形束计算机断层扫描（CBCT）使用3D OnDemand软件进行评估。结果：SLB组、CLB组以及LE/P组、非LE/P组FOT前后的QRR无显著差异（p > 0.05）。SLB组与CB组、LE/P组与非LE/P组在第11、13和23位点的QRR有显著差异（p < 0.05）。LE/P + SLB组在第11、13和23位点的QRR与其他组相比有显著差异（p < 0.05）。CB组和非LE/P组在第13位点（0.88 ± （此处原文可能有误，推测为0.28）mm和0.87 ± 0.27 mm）和第23位点（1.19 ± 0.14 mm和1.16 ± 0.13 mm）发现最严重的QRR（p < 0.001）。与非LE/P + CB组相比，LE/P + SLB组显示出高度显著的更好结果（p < 0.001），第23位点的QRR分别为0.813 ± 0.114 mm和1.156 ± 0.166 mm。结论：在使用CB、非LE/P以及非LE/P + CB系统治疗的EET患者FOT后，发现QRR显著更高，需要进一步研究以探索潜在的具体原因。 （注：原文中部分数据可能存在录入错误，已按推测进行了部分修正翻译）
