牙髓血管再生治疗年轻恒牙根尖周炎的应用

目的:观察牙髓血管再生治疗年轻恒牙根尖周炎的效果。方法:10名患者12颗牙,平均年龄10.8岁,根尖周有暗影,牙根未发育完成。术后每1~2月复查1次,连续观察6~18个月。结果:8颗牙牙根继续发育;从放置MTA至根尖发育完成的平均时间为4.6个月;牙根长度与对侧同名牙无明显差异。结论:牙髓血管再生是治疗年轻恒牙根尖周炎的有效方法。

Clinical Observation of Pulp Revascularization in Immature Teeth with Apical Periodontitis

Objective: To observe the curative effect of pulp revascularization on the immature permanent teeth with apical periodontitis. Methods: Twelve immature permanent teeth (10 patients) were involved in the study. The patients were from 8 to 12 years old, and the average age was 10.8. Every tooth had an opened apical foramina and showed a radiolucent area around the root apex. Pulp revascularization technology was used to treat the teeth. After the treatment, the patients were reviewed by clinical examination and radiograph every 1 or 2 months, and were totally followed up for 6 to 18 months. Results: The roots of 8 teeth were continually developed. The average time of development was 4.6 months. The root lengths were not different to those of symmetrical teeth. Conclusion: Pulp revascularization is effective for the treatment of immature permanent teeth with apical periodontitis.
