Progress on matrix metalloproteinase inhibitors]

Continuing advances in dentin bonding technology and adhesives revolutionized bonding of resin-based composite restorations. However, hybrid layers created by contemporary dentin adhesives present imperfect durability, and degradation of collagen matrix by endogenous enzymes is a significant factor causing destruction of hybrid layers. Bond durability can be improved by using enzyme inhibitors to prevent collagen degradation and to preserve integrity of collagen matrix. This review summarizes progress on matrix metalloproteinase inhibitors (including chlorhexidine, ethylenediaminetetraacetic acid, quaternary ammonium salt, tetracycline and its derivatives, hydroxamic acid inhibitors, bisphosphonate derivative, and cross-linking agents) and suggests prospects for these compounds.牙本质粘接混合层的长期稳定性不佳，基质金属蛋白酶等内源性酶降解胶原是导致混合层破坏的重要因素。使用酶抑制剂抑制胶原降解，维持胶原结构的完整性，是提高混合层稳定性的关键。本文重点总结了基质金属蛋白酶抑制剂（包括氯己定、乙二胺四乙酸、季铵盐类、锌离子和氧化锌、四环素类及其衍生物、异羟肟酸类抑制剂、二磷酸盐衍生物、交联剂等）的研究进展，并对未来的发展进行展望。.
