摘要: 目的: 比较3种不同托槽粘接剂和4种不同釉质抛光方法对牙釉质颜色改变的影响。方法: 选取120颗正畸需要拔除的前磨牙,随机分为3组,分别使用3种不同正畸托槽粘接剂-化学固化树脂粘接剂、光固化树脂粘接剂和树脂改性玻璃离子粘接剂,每组再随机抽取10颗牙分为4组,分别选择4种不同釉质抛光方法去除粘接剂并抛光牙釉质:碳化钨车针(TC)、碳化钨车针+Sof-Lex抛光杯(TC+SL)、碳化钨车针+One Gloss抛光杯(TC+OG)和碳化钨车针+PoGo抛光杯(TC+PG)。将上述抛光后的牙在咖啡溶液中放置7 d后,用Crystaleye分光光度比色仪进行釉质着色变化值测量。采用SPSS13.0软件包对数据进行双因素方差分析和Bonferroni法分析。结果: 不同抛光方法的组内差异表现为TC组釉质表面颜色变化差异最大,TC+SL组变化值最低,TC+SL和TC+PG组变化值无显著差异(P> 0.05)。不同粘接剂的组间差异表现为树脂改性玻璃离子粘接剂组样本着色变化值最低,化学固化树脂组样本着色变化值最高(P<0.05)。结论: 不同粘接剂类型和釉质抛光方法对釉质表面的着色变化有显著影响。

Abstract: PURPOSE: The aim of this study was to compare if there was any difference in the enamel discoloration after staining when three orthodontic adhesives and 4 enamel clean-up methods were tested. METHODS: Three types of orthodontic adhesives were used: chemically cured resin, light-cured resin and resin-modified glass-ionomer cement. A total of 120 human extracted premolars were included. Ten teeth of each orthodontic adhesive were randomly cleaned-up with 1 of 4 different procedures and stained in coffee for 7 days: carbide bur (TC), carbide bur and Sof-Lex polishers (TC+SL), carbide bur and One Gloss polishers (TC+OG), carbide bur and PoGo polishers (TC+PG). Colour measurements were made with Crystaleye dental spectrophotometer at baseline and after storage in a coffee solution for 1 week. Two way ANOVA and Bonferroni test were used for statistical analysis with SPSS 13.0 software package. RESULTS: The colour change values of adhesive materials in the TC group were the greatest. The lowest ΔE* values were obtained from the TC+SL group. However, there was no significant difference between the TC+SL and TC+PG group (P>0.05). The resin-modified glass-ionomer cement group showed the lowest colour differences and chemically cured resin group showed the highest ΔE* values among all orthodontic adhesives (P<0.05). CONCLUSIONS: The colour change of enamel surface is affected by the type of adhesive materials and clean-up procedures.
