穿孔性内部炎症性歯根吸収に対する修復的歯内療法：症例報告

Reparative Endodontic Treatment of a Perforating Internal Inflammatory Root Resorption: A Case Report.

抄録

この症例報告の目的は、側方穿孔と先端側および側方炎症性病変を伴う広範な内部炎症性歯根吸収に対する修復的治療法を提示することである。歯髄の壊死冠状部のみを除去し、吸収腔内の重要な歯髄組織と根管先端部は無処置とした。出血を誘発し、血餅を三酸化鉱骨材で覆った。硬組織の修復と根尖病変の治癒が3年後のリコールで観察された。

The aim of this case report was to present a reparative treatment approach of an extensive internal inflammatory resorption with a lateral perforation and apical and lateral inflammatory lesions. Only the necrotic coronal part of the pulp was removed, and the vital pulp tissue within the resorption cavity and the apical part of the root canal was left uninstrumented. Bleeding was induced, and the blood clot was covered with mineral trioxide aggregate. Hard tissue repair and healing of the apical lesion could be observed in the 3-year recall.
