牙髓钙化及其治疗方法的研究进展

A review of pulp calcification and its treatment methods

摘要

牙髓钙化是牙髓组织的一种增龄性变化或病理性反应，当牙髓病或根尖周病伴有牙髓钙化时，根管治疗是其最主要的治疗方式。临床治疗中，钙化根管往往因其疏通困难，难以建立准确的髓腔通路，易发生根管侧穿、台阶形成和器械分离等并发症，导致治疗失败率高，给临床医生带来巨大的困难。近年来，随着显微超声技术及引导式牙髓病学在钙化根管治疗中的应用及推广，钙化根管治疗的成功率大幅提升。本文通过文献回顾，对牙髓钙化的病因、诊断及治疗策略等方面进行详细阐述，以期为临床医生在钙化根管的治疗策略和方案的选择上提供帮助。

Abstract

Pulp calcification is an ageing change or pathologic reaction of pulp tissue. When endodontic or periapical disease is accompanied with pulp calcification, root canal therapy is the primary treatment modality. However, calcified root canals are usually hard to prepare, which can easily lead to complications such as root canal lateral penetration, step formation, and instrument separation, resulting in a high rate of treatment failure and causing great difficulties for clinicians. The success rate of calcified root canal treatment has increased significantly with the application and promotion of micro-ultrasound and guided endodontics in calcified root canal treatment. This article summarizes the etiology, diagnosis, and treatment strategies of pulp calcification based on several literature reviews to provide appropriate treatment stra-tegies and protocols for dental clinicians.
