摘要:

背景:X射线检查在根管治疗中的局限性逐渐被发现,然而相关病例的跟踪研究和有效体外模型的建立报道较少。
目的:评价X射线牙片在根管治疗中的局限性。
方法:通过对1例1年前认为需要拔除的患牙进行常规根管治疗,同时构建体外模型观察根管充填情况,分析X射线牙片在根管治疗前诊断和根管充填过程中的价值。
结果与结论:患者原需要拔除的患牙得以保留,体外模型显示不同角度观察的根管充填情况差异较大。结果提示,X射线牙片不能很好反映出根尖周的病变和根管充填情况。

Abstract:

BACKGROUND: The limitation of periapical film in root canal therapy has been gradually acquired. However, study addressing correlated case and the valid in vitro model was few reported.
OBJECTIVE: To evaluate the limitations of periapical film in root canal therapy.
METHODS: Through a tooth needed to pull out and make use of canal obturation in vitro model, the value of periapical film in root canal therapy was analyzed.
RESULTS AND CONCLUSION: The tooth originally needed to eliminate has been retained. There were comparatively large differences between canal obturation from different angle in vitro models. Periapical film can not only reflect periapical pathological changes, but also canal obturation.
