Two patients requiring surgical management for leakage of calcium hydroxide paste from a root canal into the infraorbital space are reported. A paste root canal treatment material used at the time of maxillary root canal treatment had leaked out of the root canal in both patients. Computed tomography confirmed displacement of the root canal treatment material into the soft tissue, with extension into the infraorbital space. In both cases, foreign body removal was performed. Root canal treatment using a calcium hydroxide paste should be performed carefully without strong pressure.
报告了两例因氢氧化钙糊剂从根管漏入眶下间隙而需要手术处理的患者。在上颌根管治疗时使用的一种根管治疗糊剂在这两名患者中均从根管中漏出。计算机断层扫描证实根管治疗材料移位至软组织，并延伸至眶下间隙。在这两例病例中，均进行了异物取出术。使用氢氧化钙糊剂进行根管治疗时应小心操作，避免用力过大。
