上顎犬の内周病変に伴う円周性骨下欠損の管理における血小板リッチ血漿濃縮物の有効性を評価する。左上顎犬歯内障病変を有する45歳の男性患者を対象に，初期に歯内療法を行った．歯内療法後，円周方向の骨下欠損部に血小板リッチ血漿と全形成性骨代替物を用いて治療を行った．3ヶ月後には臨床的なアタッチメントレベルの向上とプロービングの深さの減少が認められた．レントゲン写真では有意な骨充填が認められた。この結果は9ヶ月後のリコール時にも維持されていた。

To evaluate the efficacy of platelet-rich plasma concentrate in the management of a cirumferential, infrabony defect associated with an endoperio lesion in a maxillary canine. A 45 year-old male patient with an endoperio lesion in the left maxillary canine was initially treated with endodontic therapy. Following the endodontic treatment, the circumferential, infrabony defect was treated using platelet-rich plasma and an alloplastic bone substitute. At the end of three months, there was a gain in the clinical attachment level and reduction in probing depth. Radiographic evidence showed that there was significant bony fill. The results were maintained at the time of recall nine months later.
