The paper reviews the literature on the biocompatibility of dentine-bonding agents with respect to their ability to perform their defined function. Scanning electron microscope (SEM) pictures, prepared by the critical-point drying technique, are used to illustrate the various aspects of bonding to dentine such as the nature of dentine, the smear layer and the effects of primers, conditioners and etchants. From the review of the literature it can be concluded that the mechanisms of bonding to dentine are still not fully understood. The more recently introduced materials use mechanical means of adhesion where the dentine is altered by primers or conditioners to expose collagen fibres and a hybrid zone is created by the penetration of unfilled resins into this fibrous network. The irritant effects of a bonding agent on pulpal tissue may be caused by bacterial ingrowth due to initial poor bonding or a breakdown of the bond in addition to any inherent toxicity of the constituents of the bonding agent.
本文回顾了有关牙本质粘结剂生物相容性的文献，涉及其执行既定功能的能力。通过临界点干燥技术制备的扫描电子显微镜（SEM）图片用于说明与牙本质粘结的各个方面，如牙本质的性质、玷污层以及底漆、调节剂和蚀刻剂的作用。从文献综述中可以得出结论，与牙本质粘结的机制仍未完全理解。最近引入的材料采用机械粘附方式，其中底漆或调节剂改变牙本质以暴露胶原纤维，未填充树脂渗透到该纤维网络中形成混合区。除了粘结剂成分的任何固有毒性外，粘结剂对牙髓组织的刺激作用可能是由于初始粘结不良导致细菌侵入或粘结破坏所致。
