This in vitro study evaluated the effect of different cavity disinfection agents on bond strength of a silorane-based resin composite.
Thirty-six caries-free human third mandibular molars sectioned in mesio-distal direction were mounted in acrylic resin with their flat dentin surfaces exposed. After the dentin surfaces were wet ground with # 600 silicon carbide paper, the teeth were randomly divided into 6 groups of 12 each according to the cavity disinfection agents; chlorhexidine (CHX); sodium hypochlorite (NaOCl), propolis, ozone, Er,Cr:YSGG laser and no treatment (control). After treatment of dentin surfaces with one of these cavity disinfection agents, Filtek Silorane adhesive system was applied. The silorane-based resin composite, Filtek Silorane was condensed into a mold and polymerized. After storage at 37°C for 24 hours, the specimens were tested in shear mode at a crosshead speed of 1.0 mm/minute. The results were analyzed by one-way ANOVA.
No statistically significant difference was observed between the groups (p>0.05).
The use of the tested cavity disinfection agents, chlorhexidine, sodium hypochlorite, propolis, ozone and Er,Cr:YSGG laser did not significantly affect the dentin bond strength of a silorane-based resin composite, filtek supreme.
Cavity disinfectant applications did not affect the dentin bond strength of a silorane-based resin composite.
本体外研究评估了不同窝洞消毒试剂对基于硅烷的树脂复合材料粘结强度的影响。
将三十六颗无龋的人类下颌第三磨牙沿近远中方向切开，将其平坦的牙本质表面暴露，用丙烯酸树脂固定。在用600号碳化硅砂纸湿磨牙本质表面后，根据窝洞消毒试剂将牙齿随机分为6组，每组12颗；分别为洗必泰（CHX）、次氯酸钠（NaOCl）、蜂胶、臭氧、铒铬：钇-钪-镓石榴石激光以及不做处理（对照组）。用这些窝洞消毒试剂之一处理牙本质表面后，应用3M Filtek Silorane粘结系统。将基于硅烷的树脂复合材料3M Filtek Silorane填入模具并聚合。在37°C下储存24小时后，以1.0毫米/分钟的十字头速度在剪切模式下对标本进行测试。结果采用单因素方差分析进行分析。
各组之间未观察到统计学上的显著差异（p>0.05）。
所测试的窝洞消毒试剂洗必泰、次氯酸钠、蜂胶、臭氧和铒铬：钇-钪-镓石榴石激光的使用对基于硅烷的树脂复合材料3M Filtek Supreme的牙本质粘结强度没有显著影响。
窝洞消毒处理不会影响基于硅烷的树脂复合材料的牙本质粘结强度。
