Dental trauma can cause damage to the pulp tissue in immature teeth. Revascularization therapy is a possible option in the treatment of non-vital, immature permanent teeth with a history of trauma. The aim of this prospective study was to evaluate the radiographic and clinical results of immature teeth with a history of trauma treated by regenerative endodontic procedures and mineral trioxide aggregate apexification techniques.
Forty-one patients aged between 7 and 12 years with traumatized immature permanent maxillary incisors were included in the study. These patients were divided into two groups: those who had previously received endodontic treatment and those who had not. Twenty-four patients who applied directly to the university clinic and had not received endodontic treatment before were included in the regenerative endodontic protocol group (Group 1). Seventeen patients who had previously undergone endodontic intervention on their relevant teeth were included in the mineral trioxide aggregate apexification group (Group 2). The patients were followed for a period of 24 months. Clinical success rates were evaluated, and pre-treatment and control radiographs were analyzed to calculate the percentage increase in root dentin width and root length.
After 24 months of follow-up, positive periapical healing was detected in the radiographic findings in the majority of cases. In Group 1, a limited increase in root length and root dentin width was observed, while a narrowing in the apical opening was evident. The radiographic evaluation of two of the cases, which could be accessed 11 years later, emphasized the importance of long-term follow-up in assessing the effectiveness of the chosen methods.
The revascularization method is a treatment option that has positive results in terms of root development in teeth with necrotic pulp as a result of trauma.
牙外伤可导致未成熟恒牙的牙髓组织受损。再血管化治疗是治疗有外伤史的非活髓、未成熟恒牙的一种可能选择。这项前瞻性研究的目的是评估采用再生性牙髓治疗程序和三氧化矿物凝聚体根尖诱导成形技术治疗有外伤史的未成熟恒牙的影像学和临床结果。
本研究纳入了41名年龄在7至12岁之间、上颌未成熟恒牙有外伤史的患者。这些患者被分为两组：曾接受过牙髓治疗的患者和未接受过牙髓治疗的患者。24名直接到大学诊所就诊且之前未接受过牙髓治疗的患者被纳入再生性牙髓治疗方案组（第1组）。17名之前对相关牙齿进行过牙髓干预的患者被纳入三氧化矿物凝聚体根尖诱导成形组（第2组）。对患者进行了24个月的随访。评估临床成功率，并分析治疗前和对照X光片以计算牙根牙本质宽度和牙根长度的增加百分比。
随访24个月后，大多数病例的影像学检查结果显示根尖愈合良好。在第1组中，观察到牙根长度和牙根牙本质宽度有有限增加，而根尖孔变窄明显。对11年后仍可追踪的两例病例的影像学评估强调了长期随访在评估所选方法有效性方面的重要性。
再血管化方法是一种治疗选择，对于因外伤导致牙髓坏死的牙齿的牙根发育具有积极效果。
