摘要:
牙髓病和根尖周病是临床常见的口腔疾病,根管治疗是治疗这类疾病最有效的手段。髓腔通路预备即开髓,是根管治疗的首要步骤,一个设计良好的髓腔通路对于根管治疗的成功至关重要。近年来随着微创牙髓治疗学概念的提出,学者们建议对传统髓腔通路设计进行微创改良,强调有目的性地保留部分髓室顶及颈周牙本质的精细开髓,以尽可能保存健康牙体组织。虽然微创髓腔通路设计减少了牙颈部区域的应力集中,但目前没有明显的证据支持其可以提高根管治疗后牙齿的抗折性能,且微创开髓可能使治疗复杂化,增加根管治疗的难度,存在影响根管治疗效果和增加医源性损伤的风险。本文就髓腔通路设计的微创理念及其在根管治疗效果和牙齿抗折性能方面的研究进展作一综述。
