弯曲前牙的影像评价及治疗的研究进展

Research progress on imaging evaluation and treatment of anterior dilacerated teeth

前牙弯曲牙是恒前牙发育过程时,乳牙受外伤的常见后遗症之一。特征为牙冠与牙根的线性关系改变,通常以影像学资料确诊。随着临床检查手段,特别是口腔锥形束CT的使用增加,病例检出随之增加,该疾病日益受到临床医生的重视,因此治疗理念、手段和方式上也有了新发展。不同程度的弯曲前牙,在治疗上也有着不同的处理方式,因人而异,因此需要准确评估。本文回顾了近年来前牙弯曲牙的病因、流行病学、治疗方式等的研究进展,并总结了影像学评价及诊断方法,期望对相关临床工作提供参考。

Anterior dilaceration is one of the common sequelae after the dental trauma of primary teeth while the permanent anterior teeth are still growing.It is characterized by displacement of a tooth root from its normal alignment and diagnosed via radiographic data.With the improvement of examination methods,such as cone beam computed tomography,the disease has been detected more frequently and received increasing clinical attention.New thoughts and treatment methods have been reported.The treatment method depends on the degree of dilaceration,which varies among different individuals and requires accurate assessment.This article reviews the etiology,epidemiology,features,imaging evalua‐tion,diagnostic methods,and treatment methods of anterior dilaceration to provide clinical reference.
