摘要： 目的:评价牙髓血运重建术治疗年轻恒牙根尖周病的临床及影像学效果,为牙髓血运重建术的临床应用提供科学依据。方法:选择罹患根尖周病的年轻恒牙20颗进行牙髓血运重建术,术后观察18个月,每3个月进行1次临床及影像学评价。临床评价包括临床症状和体征检查,牙髓活力检测;影像学评价包括定性观察根尖周暗影是否消失,定量检测影像牙根区域和根尖孔大小改变。结果:术后18个月所有患牙均无自觉症状,无临床阳性体征,25%(5/20)的患牙可检测到牙髓活力。X线片上所有患牙根尖周暗影消失,50%(10/20)的患牙根尖孔达到完全闭合。影像牙根区域增加从28.13%(术后3个月)上升到99.28%(术后18个月);根尖孔大小缩小从21.43%(术后3个月)上升到77.05%(术后18个月)。结论:牙髓血运重建术能使根尖周炎年轻恒牙牙根继续生长。

Abstract: Objective: To evaluate the clinical and radiographic effects of pulp revascularization procedure on immature teeth with apical periodontitis. Methods: In this study, clinical and radiographic data were collected every 3 months from 20 immature permanent teeth with apical periodontitis treated with a revascularization protocol for 18 months. Clinical and radiographic evidence of healing was evaluated, and radiographic changes in the radiographic root area and apical diameter were quantified. Results: After a follow-up period of 18 months, all teeth demonstrated radiographic evidence of complete periapical healing in the absence of clinical symptoms. Five teeth showed a positive response to pulp sensibility test after 18 months. The within-case percent change in radiographic root area was 28.13% after 3 months and had increased to 99.28% after 18 months. The within-case percent change in apical diameter after 3 month was 21.43% and had increased to 77.05% by 18 months, with 50% (10 of 20) showing complete apical closure after 18 months. Conclusion: In this study, pulp revascularization allowed the continued development of roots in immature permanent teeth with apical periodontitis.
