摘　　要：背景:临床上冠修复体表面抛光处理可有效减少色素沉着及菌斑黏附,且能够降低对颌牙的磨耗。目的:研究不同抛光处理对全氧化锆修复体表面粗糙程度和细菌黏附的影响。方法:制作30个的全氧化锆试件,尺寸为10 mm×10 mm×2 mm,随机分为5组(n=6):对照组(单纯上釉处理)、抛光组(绿色碳化硅砂石、Shofu瓷抛光Kit、Ceramaster Polisher抛光)、抛光膏组(绿色碳化硅砂石、Softcut PA、Shofu瓷抛光Kit、UltraII金刚砂抛光膏)、精细抛光组(绿色碳化硅砂石、Softcut PA、Shofu瓷抛光Kit、Ceramaster Polisher抛光)、多步精细抛光组(绿色碳化硅砂石+白色氧化铝砂石、Softcut PA+Softcut PB、Shofu瓷抛光Kit、Ceramaster Polisher抛光)。测试各组试件处理后的表面粗糙度值和表面形态及表面变形链球菌黏附情况。结果与结论:①5组试件的表面粗糙度值由高到低为:抛光组、抛光膏组、多步精细抛光组、精细抛光组、对照组,抛光组粗糙度值高于其他4组(P<0.05),抛光膏组粗糙度值高于对照组、精细抛光组、多步精细抛光组(P<0.05);②扫描电镜下可见,对照组试件表面较平整未见明显划痕;精细抛光组、多步精细抛光组与对照组相似;抛光膏组试件表面的划痕深且伴有小颗粒;抛光组表试件面最不光滑,可见明显的划痕和深沟槽以及许多不规则颗粒状的突起;③5组试件表面细菌黏附量由高至低依次为:抛光组、抛光膏组、多步精细抛光组、精细抛光组、对照组,抛光组细菌黏附量显著高于其他4组(P<0.01);④结果表明,Shofu的精细抛光和多步精细抛光方案均能有效提高全氧化锆试件表面的光洁度,减少表面细菌黏附,效果堪比上釉。BACKGROUND:The polishing treatment on the surface of the crown restoration can effectively reduce pigmentation,adhesion of plaque and abrasion of the jaw teeth.OBJECTIVE:To investigate the effects of different polishing treatments on the surface roughness and bacterial adhesion of the full zirconia restoration.METHODS:Totally 30 full zirconia specimens with sizes of 10 mm×10 mm×2 mm were prepared and divided into 5 groups randomly(n=6):control group(simple glazing treatment),polishing group(green silicon carbide sandstone,Shofu porcelain polishing kit,Ceramaster Polisher polishing),polishing paste group(green silicon carbide sandstone,Softcut PA,Shofu porcelain polishing kit,Ultrall emery polishing paste),fine polishing group(green silicon carbide sandstone,Softcut PA,Shofu porcelain polishing kit,Ceramaster Polisher polishing),multi-step fine polishing group(green silicon carbide sandstone+white alumina sandstone,Softcut PA+Softcut PB,Shofu porcelain polishing kit,Ceramaster Polisher polishing).The surface roughness value,surface morphology of each specimens,and colony forming unit of bacteria on the surface of the specimens were detected after treatment.RESULTS AND CONCLUSION:(1)The surface roughness values of specimens of the five groups from high to low were:polishing group,polishing paste group,multi-step fine polishing group,fine polishing group,control group.The value was higher in the polishing group than that in other four groups(P<0.05).The value was higher in the polishing paste group than that in the control group,fine polishing group,and multi-step fine polishing group(P<0.05).(2)Under the electron microscope,the specimens of control group,fine polishing group and multi-step fine polishing group had smooth surface without visible scratches.The specimens of polishing paste group had deep scratches and small particles on the surface.The specimens of polishing group had the roughest surface with noticeable scratches,deep grooves,and many irregular granular protrusions.(3)The colony forming unit in the
