Abstract

Aim: The aim of the current study was to assess the microleakage below orthodontic brackets after bonding with three different adhesive materials.

Materials and methods: In total, 75 healthy human premolars that had been extracted for orthodontic treatment were utilized in this investigation. The samples were divided into three groups of 25 samples randomly. Premolar brackets with stainless steel bondable 0.022 slot pre-adjusted edgewise appliances were utilized. Group I: Brackets bonded with Nanocomposite Filtek Z350 XT, group II: brackets bonded with Transbond XT, group III: brackets bonded with resin-reinforced glass ionomer cement-GC Fuji Ortho LC. A surveyor applied a 200 g weight to each bracket, making minor adjustments to ensure the adhesive thickness was consistent. Thermocycling was then carried out for 1000 cycles at 5 ± 2°C to 55 ± 2°C with a dwell time of 30 s and a transfer time of 5 s. The samples were incubated in a 0.5% basic fuchsine solution for a day. Every sample was inspected using a stereomicroscope with a ×16 magnification. The data were collected and analyzed.

Results: The least microleakage was found in Transbond XT adhesive group (1.84 ± 0.12), followed by Filtek Z350 XT (1.96 ± 0.08) and GC Fuji Ortho LC (2.44 ± 0.10) group. There was a highly significant difference between the different adhesive agent groups. There was a statistically significant difference found between Filtek Z350 XT vs GC Fuji Ortho LC and Transbond XT vs GC Fuji Ortho LC with a mean difference of -0.48 and 0.60, respectively. However, there was no significant difference between Filtek Z350 XT vs Transbond XT with a mean difference of 0.12.

Conclusion: Within the limitation, the present study concluded that the Transbond XT showed better adhesive properties and least microleakage compared with Filtek Z350 XT and GC Fuji Ortho LC.

Clinical significance: There are many undesirable side effects of orthodontic therapy, including cavities, demineralization, and discoloration of the enamel. Unpleasant "white-spot lesions" or secondary caries under and around the brackets can result from microleakage between the adhesive and the base of the orthodontic bracket as well as between the adhesive and the enamel.

不同黏合剂粘接后正畸托槽下微渗漏的体外比较研究。
目的:本研究的目的是评估三种不同粘接剂粘接后正畸托槽下微渗漏的情况。材料和方法:本研究使用75颗健康的人前磨牙进行正畸治疗。将样本随机分为三组,每组25个样本。使用不锈钢粘接的0.022槽预调节边缘矫治器的前磨牙托。第一组:支架与纳米复合材料Filtek Z350 XT结合,第二组:支架与Transbond XT结合,第三组:支架与树脂增强玻璃离子水泥- gc富士Ortho LC结合。测量员在每个支架上加了200克的重量,并做了微小的调整,以确保胶粘剂的厚度一致。然后在5±2°C至55±2°C温度下进行1000次热循环,停留时间为30 s,转移时间为5 s。样品在0.5%的碱性品红溶液中孵育一天。每个样品都使用放大×16的立体显微镜进行检查。收集并分析了数据。结果:Transbond XT粘接剂组微渗漏最小(1.84±0.12),其次为Filtek Z350 XT粘接剂组(1.96±0.08),GC Fuji Ortho LC粘接剂组(2.44±0.10)。不同胶粘剂组间差异极显著。Filtek Z350 XT与GC Fuji Ortho LC和Transbond XT与GC Fuji Ortho LC的平均差异分别为-0.48和0.60,具有统计学意义。然而,Filtek Z350 XT与Transbond XT之间没有显著差异,平均差异为0.12。结论:在限定范围内,Transbond XT与Filtek Z350 XT和GC Fuji Ortho LC相比,具有更好的粘接性能和最小的微泄漏。临床意义:正畸治疗有许多不良的副作用,包括蛀牙、脱矿和牙釉质变色。不愉快的“白斑病变”或牙槽下和牙槽周围的继发性龋齿可能是由于粘接剂和牙槽底之间以及粘接剂和牙釉质之间的微渗漏造成的。如何引用本文:Singh S, Brajendu, Haque I,等。不同黏合剂粘接后正畸托槽下微渗漏的体外比较研究。[J]现代医学学报;2009;25(8):722-725。
