摘　　要：目的:探讨超声龈上洁治术对全瓷冠边缘微渗漏的影响。方法:收集形态、大小基本一致的前磨牙48颗,全瓷冠牙体预备后随机分为2组(二氧化锆冠组和玻璃陶瓷冠组,每组24颗),每组再随机分为2个亚组(树脂水门汀组和树脂改性玻璃水门汀组)。修复体粘接、固化、人工唾液保存24 h后,每个亚组内随机抽取3个样本进行超声龈上洁治60 s,另外3个样本为阴性对照组。将所有样本于室温下用5%品红溶液浸泡48 h,沿颊舌向切开,对样本冠边缘微渗漏情况进行双盲评分。采用SPSS 17.0软件包进行独立样本t检验,比较各组样本中修复体冠边缘微渗漏差异。结果:使用树脂加强型玻璃水门汀粘接的冠边缘微渗漏在超声龈上洁治后与阴性组有显著差异(P<0.05),而使用树脂水门汀粘接的冠边缘微渗漏在超声龈上洁治后与阴性组无显著差异(P>0.05)。采用同种粘接剂时,无论是否接受超声龈上洁治术,二氧化锆全瓷冠与玻璃陶瓷冠之间微渗漏均有统计学差异(P<0.05)。结论:超声龈上洁治对树脂加强型玻璃水门汀粘接的二氧化锆和玻璃陶瓷冠边缘微渗漏有显著影响,而对树脂水门汀粘接的二氧化锆和玻璃陶瓷冠边缘微渗漏无显著影响。PURPOSE:To investigate the effect of ultrasonic scaling on micro-leakage of all-ceramic crowns.METHODS:48 first premolars of the similar shape and size were collected and prepared by one attending doctor.Two groups were randomly divided(zirconia crown group and glass ceramic crown group,with 24 in each group),and each group was randomly divided into two subgroups(resin cement group and resin modified glass cement subgroup,n=6).After the crowns were bonded and solidified for 24 h,3 samples were randomly selected from each subgroup for ultrasonic scaling for 60 s,and the other 3 samples were used as the negative control group.After all samples were soaked in 5%fuchsin solution at room temperature for 48 h,buccal and lingual incisions were made,and double-blind scoring was performed for micro-leakage at the crown edge of each sample.SPSS 17.0 software package was used for statistical analysis.RESULTS:There were significant differences between the negative group and the ultrasonic group in micro-leakage of crowns which were cemented with resin modified glass cement(P<0.05),but there was no significant difference between the negative group and the ultrasonic group in micro-leakage of crowns which were cemented with resin cement(P>0.05).When the same adhesive was used,there was significant difference in microleakage between the zirconia crown and the glass-ceramic crown,whether ultrasonic supragingival scaling was performed or not(P<0.05).CONCLUSIONS:Ultrasonic scaling had significant effect on micro-leakage of crowns which were cemented with resin modified glass cement,and but had no significant effect on micro-leakage of crowns which were cemented with resin cement.
