The aim of this study was to evaluate the surface roughness of enamel after debonding with various types of burs.
The buccal surfaces of 20 mandibular incisors for each group of bur were subjected to profilometer analysis, and three parameters of surface irregularity were recorded. After bracket debonding, adhesive remnants were removed by tungsten carbide burs in low-speed, high-speed, and stainbuster settings. The samples were evaluated at pre-treatment (on sound enamel) (T1) and post-treatment (T2) by a profilometer. The specimens were measured twice, and the mean values were recorded.
The results were analyzed in intra-group comparisons with paired t-tests and in inter-group comparisons with one-way ANOVA and Tukey's HSD test. All resin removal techniques significantly increased enamel surface roughness (p<0.05). According to one-way ANOVA, there were significant differences in the effect of enamel surface roughness between all methods (p<0.05). The high-speed bur caused the maximum roughness values and the stainbuster bur caused the minimum roughness values in all the parameters (Ra, Rz, and Rq).
The three types of burs used for finishing methods revealed significant differences in the enamel surface after debonding. However, the stainbuster bur created smoother surfaces than the other applied methods.
本研究旨在评估使用不同类型车针脱粘后牙釉质的表面粗糙度。
对每组车针处理的20颗下颌切牙的颊面进行轮廓仪分析，并记录表面不规则性的三个参数。在去除托槽后，通过低速、高速和去污渍模式的碳化钨车针去除粘结剂残余物。通过轮廓仪在预处理时（健康牙釉质上）（T1）和处理后（T2）对样本进行评估。对标本进行两次测量，并记录平均值。
结果采用配对t检验进行组内比较，采用单因素方差分析和Tukey's HSD检验进行组间比较。所有去除树脂的技术均显著增加了牙釉质表面粗糙度（p<0.05）。根据单因素方差分析，所有方法在牙釉质表面粗糙度的影响上存在显著差异（p<0.05）。在所有参数（Ra、Rz和Rq）中，高速车针导致的粗糙度值最大，而去污渍车针导致的粗糙度值最小。
用于修整方法的三种类型车针在脱粘后牙釉质表面显示出显著差异。然而，去污渍车针产生的表面比其他应用方法更光滑。
