咬東西會痛卻找不到原因：顯微檢查能看見什麼？｜證據鏈
咬下或放開時出現短促疼痛，可能來自牙裂、鬆動修復體、咬合過度、牙髓發炎、牙周問題，甚至鄰牙或咀嚼肌的轉移痛。顯微鏡可放大牙面、修復體邊緣、髓室底與染色線索；配合局部咬合測試、透照、牙周探測與影像，能讓「疼痛在哪裡被誘發」變得更可核對。 但顯微鏡只能看見已暴露的表面，不能穿透牙本質，也不能單靠一條線判定裂縫深度。CBCT 對垂直牙根裂的統合敏感度約 0.70、特異度約 0.84，仍會漏掉裂縫或出現假陽性。 安全的診斷不是找一個萬能工具，而是讓多項互補證據朝同一方向收斂。

FAQ
- 看見裂紋就一定要做根管治療嗎？
- 不是。是否需要根管治療取決於牙髓診斷與裂紋涉及範圍，不是裂紋外觀本身。淺表裂紋、需要包覆的裂牙與深入牙根的裂，各有不同路徑。
- 亀裂が見えたら、必ず根管治療が必要ですか？ — いいえ。根管治療が必要かは歯髄診断と亀裂が及ぶ範囲によって決まり、亀裂の外観そのものでは決まりません。表在性のクレーズライン、被覆が必要な亀裂歯、歯根深くまで及ぶ亀裂では、それぞれ対応が異なります。
- Does Seeing a Crack Mean That Root Canal Treatment Is Always Required? — No. The need for root canal treatment depends on the pulpal diagnosis and the structures involved by the crack, not on the appearance of the crack itself. A superficial craze line, a cracked tooth requiring coverage, and a fracture extending deep into the root each follow a different pathway.
