团结起来【摘要】牙内陷是一种先天性牙齿发育畸形，解剖形态差异较大，临床上可将其分为：畸形舌侧窝、畸形根面沟、畸形舌侧尖和牙中牙。大多数学者认为牙内陷是在牙齿发育期间，牙乳头的卷折所致。因其复杂的解剖形态常常引起牙周牙髓联合病变，增大治疗难度。因此，本文就Oehlers 牙冠牙内陷Ⅲ型及畸形根面沟的分类、发病率、组织病理、临床表现、影像学特点、治疗方法等进行综述，以期为临床治

lingual cusp deformity and dens
in dente.Most scholars believe that dens invaginatus is caud by the folding of the nipple during tooth devel⁃opment.Becau of the complex anatomical shape,this condition often caus periodontal pulp joint lesions,which in⁃creas the difficulty of treatment.Therefore,this paper reviews the classification,morbidity,histopathology,clinical manifestations,imaging features and treatment methods of Oehlers crown indentation type III and malformation of the root groove to provide a reference and basis for clinical treatment.The literature review results show that the u of CBCT contributes to the diagnosis,treatment and prognosis of dens invaginatus.A personalized treatment plan should be developed
