摘要
目的:评价牙髓血运重建术用于年轻恒牙牙髓坏死的临床治疗效果。方法:选择8~16岁患者18例,因外伤或畸形中央尖折断致牙髓坏死伴不同程度的根尖周病变年轻恒牙20颗,牙根发育Nolla分期7~9期。20颗年轻恒牙均采用牙髓血运重建术,随访观察6~60个月,记录根尖周病变愈合及牙根发育情况。结果:20颗年轻恒牙经过牙髓血运重建治疗,通过6~60个月的随访观察,16颗治愈,2颗好转,2颗失败,总有效率90%。X线片示有效病例患牙根尖周阴影消失或缩小,牙根长度及根管壁厚度呈不同程度增加,部分长期随访的病例出现根尖钙化,管腔持续性窄缩。仅有2颗前磨牙复查时牙髓电活力测试结果呈阳性。结论:牙髓血运重建术治疗年轻恒牙牙髓坏死的病例,取得良好的治疗效果,术后临床症状消失,牙根继续发育,牙根延长,根管壁增厚,但远期疗效仍需长期观察随访。
Objective:To evaluate the outcome of the pulp revascularization in the treatment of immature permanent teeth with pulp necrosis.Methods:Nineteen patients aged 8~16 years were selected with 20 immature permanent teeth suffering pulp necrosis and periapical lesions due to trauma or malformed central apex breakage.The root development in Nolla stages was required 7~9.All the 20 immture permanent teeth were reconstructed by endodontic revascularization.Observed for 6~60 months,the healing and root development of periapical lesions were recorded.Results:The 6~60 months’observation on all research objects treated by the pulp revascularization showed that the clinical symptoms disappear completely with a total effective rate of 90%,in which 16 cases got cured,2 got better and 2 failed.X-rays examination showed that the periapical shadow of the affected teeth in the effective cases disappeared or shrunk,and the root length and root canal wall thickness increased in varying degrees.Some long-term follow-up cases showed apical calcification and persistent narrowing of the lumen.Only two premolar showed positive results in the electrical activity test after pulp revascularization.Conclusion:The clinical effect of the pulp revascularization procedures in the treatment of immature permanent teeth with pulp necrosis was satisfactory.The clinical symptoms disappear after the operation,and the root continues to grow,the canal wall thickened,and apical closure.
