{Abstract}: Dentin dysplasia type Ⅱ (DD-Ⅱ) is a subtype of hereditary dentin disorders. The dentin sialophosphoprotein (DSPP) gene has been revealed to be the causative gene, whose mutations could affect the normal tooth development process. The lesions involve both deciduous and permanent dentition, mainly manifested as tooth discoloration, attrition and even the subsequent malocclusion. If not treated in time, it will significantly affect the physical and psychological health of patients. The disease is difficult to be diagnosed in clinic accurately as its low incidence and hidden manifestations. The present article aims to discuss the clinical and radiographic characteristics, diagnosis, treatment of DD-Ⅱ, in order to improve the overall understanding on DD-Ⅱ for clinicians.<BR>Ⅱ型牙本质发育不良是遗传性牙本质发育异常的一个亚型，致病基因为牙本质涎磷蛋白基因，其突变导致牙齿正常发育过程受到影响。病变可累及乳牙列和恒牙列，主要表现为牙齿变色、磨耗，甚至继发咬合关系异常，如未及时治疗将显著影响患者的身心健康。该疾病在人群中患病率低，表型隐匿，临床诊断困难。本文主要对Ⅱ型牙本质发育不良的临床和影像学特征、诊断、鉴别诊断及治疗等方面进行阐述，以期提高临床医师对Ⅱ型牙本质发育不良的全面认识。.
