摘要： 根管治疗的主要目的是清除感染根管系统中的微生物,但是单独应用机械预备并不能完全清除感染,因此临床上还会应用各种消毒和冲洗药物。然而,研究表明这些药物可能影响牙本质的化学组成、力学性能,最终降低牙齿的抗折强度、根管治疗的成功率等。本文针对根管用药对于牙齿力学性能的影响进行文献回顾,并从牙根抗折性能的角度对于根管用药的安全性进行评价。

关键词: 冲洗药物, 消毒药物, 根管, 抗折强度, 显微硬度

Abstract: One of the main goals of the root canal treatment is the elimination of microorganisms from the contaminated root canal system. Instrumentation alone will not allow for adequate debridement and disinfection of the complex root canal system. Therefore, some irrigants or disinfectants are required. However, these medications can affect the components of dentine and influence the mechanical properties of root; at last, it can decrease the fracture resistance of teeth, the rate of success in endodontic treatment. The aim of this paper is to review the influence of intracanal medications on mechanical properties of teeth and evaluate their safety.

Key words: irrigants, disinfectants, root canal, fracture resistance, microhardness
