【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 imaging effects of pulp revascularization in the treatment of periapical disease of young permanent teeth. Methods: twenty young permanent teeth with periapical disease were selected for pulp reconstruction and 18 months after operation. Clinical and imaging evaluations were performed every 3 months. Clinical evaluation included clinical symptoms and signs, pulp vitality, and qualitative observation of the disappearance of periapical shadow. The changes of root area and apical foramen were measured quantitatively. Results: there were no symptoms in all teeth 18 months after operation. All periapical shadow disappeared on X ray film. The apical foramen of the affected tooth was completely closed. The image root area increased from 28.13 (3 months after operation) to 99.28% (postoperative 3 months). The size of apical foramen decreased from 21.43 to 77.05 (18 months after operation). Conclusion: the root of young permanent teeth with periapical periodontitis can continue to grow.
