摘要
目的探讨CompothixoTM充填器、传统充填器、SonicFill声波手机3种充填器对树脂充填Ⅱ类洞效果的影响。方法选取2020年10月至2021年2月山东第二医科大学附属医院(潍坊医学院附属医院)口腔科拔除的恒磨牙共40颗,随机分为A、B、C、D四组。在离体牙的近中、远中分别制备标准Ⅱ类洞,按各分组要求进行树脂充填,经温度循环、亚甲蓝染色后剖开,体视显微镜下观测牙体组织与修复体轴壁和龈壁的染料渗透深度并分级,计算微渗漏程度评分。结果四组中均有样本发生微渗漏,经Mann-Whitney U检验,A组龈壁微渗漏评分高于另外三组(P<0.05);B组与C组比较差异无统计学意义(P>0.05);B组、C组均高于D组(P<0.05)。A组轴壁微渗漏评分高于D组(P<0.05),其余组间比较差异无统计学意义(P>0.05)。结论与传统充填器相比,CompothixoTM充填器有利于减少树脂与牙体组织间微渗漏;与使用SonicFill声波手机相比,使用CompothixoTM充填器并没有减少SonicFill超声树脂与牙体组织间微渗漏。
Objective To compare the effects of using three different filling appliances,CompothixoTM resin filler,conventional resin filler,and SonicFill sonic handpiece,on marginal microleakage after auxiliary resin filling of classⅡcavities.Methods A total of 40 permanent molars extracted from the Department of Stomatology,Affiliated Hospital of Shandong Second Medical University(Weifang Medical University Affiliated Hospital)from October 2020 to February 2021 were collected and randomly divided into four groups:A,B,C,and D.Standard classⅡcavities were prepared in the proximal and distal middle of the isolated teeth,filled according to the standard filling requirements of the instruments in each grouping,dissected after temperature cycling and methylene blue staining,and the dye penetration depths of the dental tissues and restorative axial and gingival walls were observed and graded under the body-view microscope to calculate the microleakage degree scores.Results Microleakage occurred in four groups,and tested by the Mann-Whitney U test,the microleakage scores of group A was higher than those of the other three groups(P<0.05);There was no statistically significant difference between groups B and C(P>0.05);The scores of groups B and C were higher than those of group D(P<0.05).Group A had higher microleakage scores than group D(P<0.05),and there was no statistically significant difference between the remaining groups(P>0.05).Conclusion The use of the CompothixoTM resin filler is beneficial in reducing microleakage between the resin and the tooth tissue when compared to conventional filling appliances;Compare with the SonicFill handpiece,the use of the CompothixoTM resin filler is not conducive to the reduction of microleakage between the SonicFill ultrasonic resin and the tooth tissue.
