The major objective in endodontic therapy is to achieve complete chemomechanical debridement of the entire root canal system. This can be accomplished with biomechanical instrumentation and chemical irrigation. Various endodontic irrigants, such as sodium hypochlorite, chlorhexidene, and iodine potassium iodide, are available, each having its own advantages with some limitations. MTAD, a new endodontic irrigant, has been introduced to fulfill these limitations. MTAD is a mixture of doxycycline, citric acid, and a detergent (Tween 80). Since its introduction, it is a material that has been researched extensively for its properties. This article presents a review on the numerous properties of MTAD, such as antimicrobial activity, smear layer- and pulp-dissolving capability, effect on dentin and adhesion, and biocompatibility.
牙髓治疗的主要目标是实现整个根管系统的彻底化学机械清创。这可以通过生物力学器械操作和化学冲洗来完成。有多种牙髓冲洗剂可供使用，如次氯酸钠、氯己定和碘化钾，每种冲洗剂都有其自身的优点，但也存在一些局限性。一种新型牙髓冲洗剂MTAD已被引入以弥补这些局限性。MTAD是强力霉素、柠檬酸和一种去污剂（吐温80）的混合物。自推出以来，它因其特性而受到广泛研究。本文对MTAD的众多特性进行了综述，如抗菌活性、溶解玷污层和牙髓的能力、对牙本质和黏附的影响以及生物相容性。
