The aim of this review is to discuss the role of medicaments and materials used in teeth undergoing root canal treatment and how they affect the overall prognosis of root canal treated teeth. Irrigants, medicaments and materials play a vital role in RCT. They reduce the overall microbial load within the root canal system, help reduce inter-appointment pain, and induce apexification during RCT of permanent teeth with immature apices. In addition, they also help create a hermetic coronal and periradicular seal to entomb any residual microorganisms within the canals and prevent future ingress of contaminants into the root canal system and subsequent reinfection. Whilst the role of various materials in RCT has been thoroughly investigated, the available literature and longitudinal clinical studies evaluating the affect of such materials on the prognosis of RCT is scarce, and requires further investigation.
本综述的目的是讨论用于根管治疗牙齿的药物和材料的作用，以及它们如何影响根管治疗牙齿的整体预后。冲洗剂、药物和材料在根管治疗中起着至关重要的作用。它们可降低根管系统内的总体微生物负荷，有助于减轻复诊间疼痛，并在根尖未成熟恒牙的根管治疗期间诱导根尖形成。此外，它们还有助于形成密闭的冠部和根尖周密封，将根管内的任何残留微生物包裹起来，防止未来污染物进入根管系统并随后再次感染。虽然各种材料在根管治疗中的作用已得到充分研究，但评估此类材料对根管治疗预后影响的现有文献和纵向临床研究却很少，需要进一步调查。
