关于根尖止点的思考
分享一例预期性漏斗状根尖孔案例:其解剖性根尖孔明显位于影像学根尖冠方。
根管治疗只有一个正确的终止位置:根尖狭窄区——即根管在口腔外界开口前最狭窄的部位。
多数人会认为此例充填"长度不足"。实际上,该根管充填距离影像学根尖尚有近5毫米。 但果真属于欠填吗?
有时,我们需要依靠专业知识而非肉眼进行判断。根管治疗的终止点应基于解剖学标志而非单纯影像学表现,根尖狭窄区才是真正意义上的生理性根尖止点。此例虽在X线片上呈现"短填",实则精确终止于生物性根尖界面,体现了对根尖解剖结构的充分尊重。
Reflection on the Apical Limit
Sharing a case with an anticipated, funnel-shaped foramen ending well short of the radiographic apex.
There is only one correct place to terminate procedures: the apical constriction, the narrowest diameter before the external opening.
Many would call this filling “too short.” In fact, the obturation ends nearly 5 mm from the radiographic apex.
But is it really short?
Sometimes, it’s about seeing with knowledge, not just with the eye.#牙医IG翻动派[超话]#
