A case of external inflammatory root resorption and labial fenestration in a maxillary central incisor is presented. The root canal was dressed with pure calcium hydroxide mixed with normal saline for 1 month before it was obturated with gutta percha and apicoectomy surgery undertaken to attempt primary closure of the fenestration. The PDL and the fenestration healed uneventfully.
本文报告一例上颌中切牙发生外部炎性牙根吸收及唇侧开窗的病例。在根管充填牙胶尖之前，根管先用纯氢氧化钙与生理盐水混合进行封药1个月，并进行根尖切除术以尝试初步封闭开窗处。牙周膜和开窗处愈合良好。
