根管做完還痛，是漏根管還是別的問題？｜證據鏈
根管治療後短期按壓或咬合敏感，與數月後仍反覆疼痛，是不同情境。後者可能涉及遺漏根管、冠部滲漏、持續根尖周發炎、牙裂、咬合負荷，也可能來自鄰牙、顳顎關節、咀嚼肌或神經相關疼痛。先定位疼痛來源，才知道再治療是否會處理到原因。 一項多中心前瞻隊列在 651 位完成六個月追蹤者中，有 65 位（10.0%）符合持續疼痛定義。 另一項針對六個月仍痛者的深入檢查，是 38 位符合疼痛條件者中同意受檢的 19 位（50%）；其中 37% 為牙源原因、42% 為非牙源原因、11% 同時有兩類原因，另有 11% 在臨床評估當下已不再符合疼痛條件。 分母很小又有自我選擇，不能當作一般門診比例；它真正提醒的是：症狀持續時，直接重做根管可能處理錯對象。

FAQ
- 根管做完咬痛，就是漏根管嗎？
- 不是。局部高點、根尖周組織恢復、牙裂、修復滲漏與鄰牙問題都可能咬痛。遺漏根管是需要檢查的假說之一，不是症狀的同義詞。
- 根管治療後に噛むと痛むのは、未処置根管があるからでしょうか？ — いいえ。局所的な咬合の高い箇所、根尖周囲組織の回復、歯の亀裂、修復物からの漏洩、隣在歯の問題はいずれも、咬合痛を起こし得ます。未処置根管は検討すべき仮説の一つであり、症状の同義語ではありません。
- Does pain on biting after root canal treatment mean there is a missed canal? — No. A local high spot, recovery of the periapical tissues, a tooth crack, leakage from a restoration and a problem in an adjacent tooth can all cause pain on biting. A missed canal is one hypothesis that needs investigation, not a synonym for the symptom.
