Effective shaping and cleaning of root canals are essential for the success of endodontic treatment. Due to the complex anatomy of root canal spaces, the use of various instrumentation techniques alone is not effective in producing bacteria-free root canal spaces. Irrigation, disinfectants, rinses, and intervisit medications are used in conjunction with the mechanical instrumentation to ensure the success of endodontic treatment. Sodium hypochlorite (NaOCl), a halogenated compound, is routinely used to irrigate the root canal during endodontic treatments. NaOCl has been known for its antibacterial action, proteolytic and dissolution capacity, and debridement properties. NaOCl, however, can alter the composition of dentin and hence its interaction with the adhesive resins used to bond the restorative materials to treated dentin. This review therefore covers in depth the action of NaOCl on dentin-adhesive resin bond strength including both enhancement and reduction, then mechanisms proposed for such action, and finally how the adverse action of NaOCl on dentin can be reversed.
有效的根管塑形和清洁对于根管治疗的成功至关重要。由于根管空间的解剖结构复杂，仅使用各种器械技术并不能有效地产生无菌的根管空间。冲洗、消毒剂、冲洗液和治疗间隙用药与机械器械一起使用，以确保根管治疗的成功。次氯酸钠 (NaOCl) 是一种卤代化合物，在根管治疗期间通常用于冲洗根管。NaOCl 具有抗菌作用、蛋白水解和溶解能力以及去污特性。然而，NaOCl 会改变牙本质的成分，从而影响其与用于将修复材料粘结到处理过的牙本质的粘合树脂的相互作用。因此，本综述深入探讨了 NaOCl 对牙本质-粘合树脂粘结强度的作用，包括增强和降低，然后提出了这种作用的机制，最后探讨了如何逆转 NaOCl 对牙本质的不利作用。
