The aim of the current research was to evaluate the efficacy of different fluoride-releasing bonding products in preventing enamel demineralization around orthodontic brackets by using a scanning electron microscope (SEM).
This research was performed using 80 healthy human premolar teeth that were extracted in course of orthodontic therapy. Until use, the sample premolars were subjected to storage in 0.1% thymol. Each premolar was thereafter cleansed with pumice for 10 seconds. Stainless steel brackets for premolars were employed. The 80 samples were allocated at random to one of the four groups (20 in each) as follows: Group I, control; group II, Transbond Plus color change adhesive; group III, GC Fuji Ortho LC; and group IV, Vitremer. An hour following bonding, all samples were subjected to pH cycling at a temperature of 37°C for a 14-day period. The premolar teeth were assessed below SEM. Analysis was performed with the one-way analysis of variance. Statistical significance was set at a -value less than 0.05.
The extreme area of demineralization was abridged by the use of Transbond Plus color change adhesive (108.19 ± 0.68), trailed by GC Fuji Ortho LC (119.24 ± 0.37) use, Vitremer (121.56 ± 0.92) as well as the control group (141.88 ± 1.09) in that order. And there was a statistically significant difference found between the groups ( <0.001). Tukey's honestly significant difference (HSD) was employed in an overall comparison of mean areas of enamel demineralization, which depicted that differences were significant statistically with the exception of group III and group IV.
The current research came to a conclusion that the Transbond Plus color change adhesive group was more potent in significant inhibition of demineralization areas in comparison to GC Fuji Ortho LC group and Vitremer group.
In course of fixed orthodontic therapy, demineralization of enamel is an inherent occurrence. Multiple approaches are being continually developed to avoid the formation of white spot lesions (WSLs) that compromise esthetics and cause deprived remineralization that enhances the menace of dental caries. Bonding agents that can release fluorides are thus considered highly efficacious.
本研究旨在通过扫描电子显微镜（SEM）评估不同释氟黏接产品在预防正畸托槽周围釉质脱矿中的疗效。
本研究采用 80 颗在正畸治疗中拔除的健康人恒前磨牙，样本在使用前置于 0.1%麝香草酚中储存。此后，用浮石清洁每个前磨牙 10 秒。使用前磨牙不锈钢托槽。将 80 个样本随机分为四组（每组 20 个）：I 组，对照组；II 组，Transbond Plus 变色黏接剂；III 组，GC Fuji Ortho LC；IV 组，Vitremer。黏接后 1 小时，所有样本在 37°C 下进行 pH 循环，持续 14 天。在 SEM 下评估前磨牙。采用单因素方差分析进行分析。统计显著性设为 - 值小于 0.05。
Transbond Plus 变色黏接剂（108.19 ± 0.68）的使用缩短了脱矿区的极端面积，其次是 GC Fuji Ortho LC（119.24 ± 0.37）、Vitremer（121.56 ± 0.92）和对照组（141.88 ± 1.09）。组间存在统计学差异（<0.001）。采用总体比较釉质脱矿平均面积的 Tukey Honestly Significant Difference（HSD），表明除了 III 组和 IV 组外，其余组间差异均有统计学意义。
本研究得出的结论是，与 GC Fuji Ortho LC 组和 Vitremer 组相比，Transbond Plus 变色黏接剂组在显著抑制脱矿区方面更有效。
在固定正畸治疗过程中，釉质脱矿是一种固有现象。为了避免形成影响美观并导致脱矿再矿化受损从而增加龋齿威胁的白垩斑（WSL），人们不断开发多种方法。因此，能够释放氟化物的黏接剂被认为是非常有效的。
