A three-dimensional cavity design was used to test the bond strength between restorative materials and tooth structure. Results indicated that bonding agents that rely on mechanical retention to the dentinal smear layer produced relatively low bond strengths. Bonding agents that require smear layer modification yielded mixed results, possibly because of differences in chemical formulation. The three-dimensional cavity design employed in this study is a replicable one, allowing the creation of standardized, clinically relevant preparations.
采用三维洞形设计来测试修复材料与牙体组织之间的粘结强度。结果表明，依赖于与牙本质玷污层机械固位的粘结剂产生的粘结强度相对较低。需要对玷污层进行改性的粘结剂产生的结果不一，这可能是由于化学配方的差异。本研究中采用的三维洞形设计是可重复的，能够创建标准化的、与临床相关的预备洞形。
