摘　　要：牙内陷是一种罕见的牙齿发育畸形,牙内陷除在常规的口腔检查中能早期发现外,患者出现症状就诊时即已发生牙髓或根尖周病变。显微镜及CBCT扫描技术的应用在牙内陷的诊断和治疗过程中发挥非常重要的作用。该文通过对2例牙内陷畸形临床诊断和治疗方法的探索和分析,回顾了牙内陷畸形的病理特点,总结了牙内陷畸形的诊断及治疗原则。Dens invaginatus is an unusual malformation. The difficulty in recognizing a tooth with dens invaginatus frequently results in the delayed diagnosis followed by unpromising treatment outcome because the abnormality cannot be seen until the tooth is involved with pulp necrosis even apical periodontitis. The application of CBCT scanning and dental microscope is playing a significantly important role in both diagnosis and treatment of dens invaginatus. This paper presents 2 cases with dens invaginatus which were well diagnosed and properly treated,reviews the pathology and intends to get the principle ideas for the diagnosis and treatment of dens invaginatus.
