外伤后未成熟前牙的牙髓和根尖周病变是经常发生的,在这种情况下,开放顶点的管理对牙髓学家构成了持续的挑战。这是由于不存在将导致管系统内的闭塞材料的不良三维密封/适应性的顶端收缩。用长期氢氧化钙治疗未成熟的无髓牙齿可能会削弱牙本质并增加骨折的敏感性。用生物活性剂如Biodentine/矿物三氧化物聚集体(MTA)完全封闭根管与根尖化相比具有诸如增加的抗断裂性的益处。当用于闭塞时,Biodentine™,一种新型硅酸钙基水泥,性能优于其他波特兰水泥衍生物。此病例报告显示了开放的心尖和根尖周围病变的六个月随访结果,该病变涉及上颌右中切牙#11,其中Biodentine闭塞术先前曾接受三重抗生素糊剂作为管内药物治疗三周。在本文中的六个月随访结束时,随着根尖周射线不透性大小的减小,牙齿11的令人满意的愈合率是非常可观的。
Pulpal and periapical pathosis in an immature anterior tooth following traumatic injury is a frequent occurrence, and management of open apices in such cases poses a constant challenge to endodontists. This is due to the absence of apical constriction that would result in poor three-dimensional seal/adaptation of the obturated material within the canal system. Treatment of immature pulpless teeth with long-term calcium hydroxide may consequently weaken the dentin and increase the fracture susceptibility. Obturating the root canals completely with bioactive agents like Biodentine/mineral trioxide aggregate (MTA) has benefits like increased fracture resistance when compared to apexification. When used for
obturation, Biodentine™, a new calcium silicate-based cement, performs superior to other Portland cement derivatives. This
case report demonstrates a six-month follow-up result of an open apex and a periapical lesion involving maxillary right central incisor #11 with the Biodentine
obturation that was previously subjected to triple antibiotic paste as an intra-canal medicament for three weeks. The satisfactory healing rate of tooth 11 with the reduction in the size of periapical radiolucency at the end of the six-month follow-up in this current article is highly considerable.
