摘要

The pulp chamber morphology, the number of root canals, and the root canal configuration of the primary teeth often exist variations, and hence, the clinicians should always remember deeply the internal morphology of teeth such as pulp chamber and root canals at all times to achieve good quality in endodontic treatment. Missed root canals during root canal therapy is a common cause of endodontic treatment failure and may lead to postoperative pain, recurrent inflammation, and even treatment failure. Proper magnification tools and accurate images can help clinicians reduce the likelihood of missed root canals and even treatment failure. This is a case report of "the mandibular primary second molar with five root canals" treated with pulpectomy, glass ionomer fillings, and stainless steel crown (SSC) restoration. 14 months after treatment, a follow-up appointment revealed a good treatment outcome.

乳牙牙髓腔型態、牙根根管數量、牙根根管型態在臨床治療時常存在變異，齒內治療時，尤其要隨時謹記牙髓腔、牙根管等齒內型態，才可達到好的治療品質。根管治療時若有遺漏根管未治療，為常見的齒內治療失敗原因之一，可能導致術後疼痛、反覆發炎甚至治療失敗，適當的放大工具與精確的影像可幫助臨床醫師減少遺漏根管而導致治療失敗的可能性。本篇案例報告為一個「五根管下顎第二乳臼齒」的治療案例，該案例接受齒髓切除術治療、玻璃離子體填補與不鏽鋼牙套復形，經過14個月的術後追蹤，治療成效良好。
