简介：对一名9岁男孩的未成熟下颌右第一磨牙（#30）进行了血管再生/再生治疗，在该牙齿上使用富血小板血浆（PRP）和血凝块的混合物或单独使用WOO凝块。方法：30号牙：在血运重建/再生手术后2年1个月骨折，无法保存。拔牙，并进行组织学检查。来确定运河中形成的组织的性质结果如下：在临床上，根管治疗的情况下是成功的基础上解决根尖周炎和临床体征和症状的消失。在组织学上，无论是否进行PRP治疗，远端和近中根管内形成的组织均为矿化组织，类似于牙骨质/类骨质组织和未发炎的纤维结缔组织。无“组织特征为存在成牙本质细胞样细胞，极化。沿着牙本质样矿化组织。结论：根管组织形成于根管内，根管由矿化组织和纤维结缔组织组成.在牙本质样矿化组织中未观察到以成牙本质细胞样细胞存在为特征的牙髓样组织。（J Endod 2013;39：138-144）
Introduction: An immature mandibular right first molar (#30) with apical periodontitis of a-9-year-old boy was treated With a revascularization/revitalization procedure Using either a mixture of platelet:rich plasma (PRP) and a blood clot Or a WOO clot alone on the seine tooth. Methods: Tooth #30: fractured 2 years and 1 month after the revascularization/revitalization procedure and Could not be saved. The tooth was extracted, and processed for histologic examination. to determine the nature Of the tissues that formed in the Canals. Results: Clinically, the endodontic treatment of the,case was successful based on the resolution of apical periodontitis and the absence of clinical signs and Symptoms. Histologically, the tissues formed in the distal, and mesial canals were mineralized tissue similar to cemenitoid/osteoid tissue and uninflamed fibrous connective tissue regardless of PRP or no PRP treatment. No " tissue characterized by the presence of odontoblast-like Cells, polarized. along the dentin-like mineralized :tissue was observed. Conclusions: The tissues:formed in,the canals were Mineralized tissue and some fibrous Connective tissue. No pulp-like tissue characterized by the presence of odontoblast-like cells Was observed lining the dentin-like Mineralized tissue. (J Endod 2013;39:138-144)
