To evaluate the microleakage at the enamel-dentin resin-based composite (RBC) interface of 4 dentin bonding systems (DBS).
Standardized kidney-shaped Class V cavities were prepared on the buccal and lingual surfaces at the cemento-enamel junction of 90 extracted human teeth and restored with a microhybrid RBC (Filtek P60) following application of either Excite (EXC), a single component adhesive; Prompt L Pop (PLP), a self-etching priming bonding adhesive; Clearfil SE Bond (SEB), a self-etching adhesive; or OptiBond Solo (OPS), a single component adhesive. The teeth were thermocycled, immersed in a dye solution and sectioned. The enamel failures and the occlusal and cervical dentin microleakages were measured.
Significant differences were evident between the self-etching adhesives and the adhesives using phosphoric acid (P 0.05) for the enamel. The occlusal dentin microleakage was similar for the four DBS. PLP presented the worst values at the cervical dentin margin compared to the three other DBS. Significant differences were noted between PLP and EXC and OPS, which performed better.
评估4种牙本质粘结系统（DBS）在牙釉质-牙本质树脂基复合材料（RBC）界面处的微渗漏情况。
在90颗拔除的人牙牙骨质-釉质界的颊面和舌面制备标准化的肾形V类洞，在应用单组分粘结剂Excite（EXC）、自酸蚀底涂粘结剂Prompt L Pop（PLP）、自酸蚀粘结剂Clearfil SE Bond（SEB）或单组分粘结剂OptiBond Solo（OPS）后，用微混合RBC（Filtek P60）进行修复。对牙齿进行热循环处理，浸入染料溶液中并切片。测量釉质破坏情况以及咬合面和颈部牙本质的微渗漏情况。
自酸蚀粘结剂与使用磷酸的粘结剂在釉质方面存在显著差异（P < 0.05）。4种DBS的咬合面牙本质微渗漏情况相似。与其他3种DBS相比，PLP在颈部牙本质边缘的情况最差。PLP与表现较好的EXC和OPS之间存在显著差异。
