To evaluate the effectiveness of apexification versus revascularization in the treatment of necrotic immature teeth and determine which strategy affords the greatest radiological success rate.
An analysis was made of 18 teeth subjected to mineral trioxide aggregate (MTA) apical plugging and regenerative endodontic treatment, assessing healing of the apical lesions and the changes in root dimensions.
Significantly greater root growth was observed with revascularization in terms of the percentage change in length (12.75% at 6 months) and dentin thickness (34.57% at 6 months) (p < 0.05). There were no significant differences between the two treatments in terms of the apical healing scores after 6 months of follow-up (p > 0.05).
Apexification with an MTA apical plug and pulp regeneration are reliable treatments for non-vital immature teeth. The radiographic outcomes are comparable between the immature teeth subjected to MTA apexification versus those subjected to revascularization. The results of the present study indicate a greater increase in root length and width with regenerative endodontic treatment.
评估根尖诱导成形术与血管再生术治疗感染性年轻恒牙的效果，以确定哪种策略的放射成功率最高。
分析了 18 颗接受矿化三氧化物凝聚体（MTA）根尖堵塞和再生性牙髓治疗的牙齿，评估了根尖病变的愈合情况和根尺寸的变化。
在长度变化百分比（6 个月时为 12.75%）和牙本质厚度变化百分比（6 个月时为 34.57%）方面，血管再生术的根生长显著更大（p<0.05）。在 6 个月的随访后，两种治疗方法的根尖愈合评分没有显著差异（p>0.05）。
用 MTA 根尖塞和牙髓再生进行根尖诱导成形术是治疗非活力年轻恒牙的可靠方法。接受 MTA 根尖诱导成形术和接受血管再生术的年轻恒牙的放射学结果相似。本研究结果表明，再生性牙髓治疗可使根长和根宽显著增加。
