根管治療の失敗は、患者さんの訴えに基づいて、臨床検査やレントゲン所見に基づいて判断することができます。失敗の兆候や症状の多くは、痛みや不快感、周囲の軟部組織の腫脹や洞形成、対象となる歯の変色などである。手技中の機械的穿孔、根管の過充填・過少充填、根管の欠損・未充填などが失敗例の主な要因である。本症例は、以前に根管治療を受けた上側切歯が変色し感染した症例である。この歯は非外科的治療と外科的再治療を経て、内部漂白と完全なポーセレンベニアで治療された。12ヶ月間のレビューでは、歯頂組織の治癒と許容可能な歯の外観が観察された。

Root canal treatment failure can be determined based on a patient's complaint and on the basis of clinical examination and radiographic findings. Most of the signs and symptoms for the failure are pain and discomfort, swelling and sinus formation at the surrounding soft tissue, and discoloration of the subjected tooth. Factors such as mechanical perforation during the procedures, overfilled or underfilled root canal, and missed or unfilled canals are the main factors for the failure outcome. This case report presents a discolored and infected upper lateral incisor which was previously root canal treated. The tooth was successfully managed under nonsurgical and surgical retreatment followed by an internal bleaching and full porcelain veneer. Apical tissue healing and acceptable tooth appearance was observed during a 12-month review.
