The current case study evaluated the effect of vital pulp therapy on a human dental pulp after a long-term period using micro-computed tomography (MCT) for the first time. In the presented report, the successful outcomes of full pulpotomy using calcium-enriched mixture (CEM) cement on an irreversible pulpitis case were documented clinically/radiographically over 5 years. Due to an unrestorable crown fracture at the 5-year recall, the tooth was extracted and evaluated by MCT; the images showed that CEM pulpotomy allowed the dental pulp to create complete dentinal bridges without pulp canal obliteration (PCO). These MCT results showed that CEM pulpotomy, as a bio-regenerative treatment, caused no negative consequence of PCO or calcific metamorphosis on dental pulp over the long term.
本病例研究首次使用微型计算机断层扫描（MCT）评估了长期生命牙髓治疗对人类牙髓的影响。在本报告中，临床上/放射学上记录了在一例不可逆性牙髓炎病例中使用富钙混合物（CEM）粘固粉进行完全牙髓切断术超过5年的成功结果。由于在5年复查时出现无法修复的冠折，该牙齿被拔除并通过MCT进行评估；图像显示，CEM牙髓切断术使牙髓形成了完整的牙本质桥，而没有出现根管闭锁（PCO）。这些MCT结果表明，作为一种生物再生治疗方法，CEM牙髓切断术在长期内对牙髓没有造成PCO或钙化变形的负面后果。
