The advent of "Adhesive Dentistry" has simplified the guidelines for cavity preparation enormously. The design and extent of the current preparations are basically defined by the extent and shape of the caries lesion, potentially slightly extended by bevelling the cavity margins in order to meet the modern concept of minimally invasive dentistry. New caries excavation techniques have been introduced, such as the use of plastic and ceramic burs, improved caries-disclosing dyes, enzymatic caries-dissolving agents, caries-selective sono/air abrasion and laser ablation. They all aim to remove or help remove caries-infected tissue as selectively as possible, while being minimally invasive through maximum preservation of caries-affected tissue. Each technique entails a specific caries-removal endpoint and produces residual dentin substrates of different natures and thus different receptiveness for adhesive procedures. This paper reviews the newest developments in caries excavation techniques and their effect on the remaining dentin tissue with regard to its bonding receptiveness.
“黏附性牙科”的出现极大地简化了窝洞预备的指导原则。目前预备的设计和范围基本由龋损的范围和形状决定，为了满足微创牙科的现代概念，可能会稍微扩展边缘斜面。已经引入了新的龋损挖除技术，如使用塑料和陶瓷车针、改良的龋蚀显色剂、酶性龋蚀溶解剂、龋蚀选择性声/空化喷砂和激光烧蚀。它们的目的都是尽可能有选择性地去除或帮助去除受感染的龋损组织，同时通过最大程度地保留受龋损影响的组织来实现微创。每种技术都有特定的龋损去除终点，并产生不同性质的残余牙本质基质，因此对黏附性处理的接受程度也不同。本文综述了龋蚀挖除技术的最新进展及其对剩余牙本质组织的黏附性的影响。
