A Case of Periodontal Necrosis following Embolization of Maxillary Artery for Epistaxis

Figure 1

Temporal changes in the gingiva around the left upper teeth. (a) At the initial visit, plaque and calculus were observed on the tooth surface (arrowhead), and pockets had developed especially around his maxillary left first molar, which had been capped in silver. (b) Nine days after embolization, necrotizing ulcer formation was observed on the gingiva on the palatal side of the maxillary left premolar and molar teeth. The alveolar bone was exposed due to loss of gingiva (arrow). (c) At 2 weeks after treatment, resorption of the alveolar bone had occurred, and the palatal side of the first molar was fully exposed. Granulation tissue proliferated around the edge of the defect. (d) At 2 months after treatment, the wound was replaced by granulation tissue and epithelialized almost completely, with the exception of the deep socket on the palatal side.
