根管治疗中常见操作失误(3)——根管预备操作失误

Common procedure errors in root canal treatment(3)——Procedure errors in root canal preparation

根管预备目的是通过根管清理彻底去除根管内坏死组织、细菌及其代谢产物、牙本质碎屑,并为根管严密充填建立理想形态。如处理不当会导致根管偏移、台阶形成、根管堵塞、根管侧穿、器械折断等。第三部分主要介绍根管预备操作失误,旨在为临床医生提供理论和实践参考。

The purpose of root canal preparation is complete removal of necrotic tissue, bacteria and byproducts, dentin debris, and the establishment of an ideal shape for obturation of the root canal system. The improper operation during the preparation would cause root canal deviation, elbow formation, root canal plug and perforation, instrument fracture and other procedure errors. The objective of this article is to discuss the procedure errors during the root canal preparation, and provide the clinicians with current information and strategies for management in the practice.
