Dentinogenesis imperfecta is a hereditary condition characterized by disturbance in tooth formation. The colour of the teeth vary from opalescent greyish-blue to an amber-like colour on the teeth with splitting of the enamel. On the roentgenogram the marked obliteration of the pulp chambers is a characteristic feature. This case report describe a 13-year-old boy with dentinogenesis imperfecta. High caries activity resulted in extensive caries on the first permanent molars. The boy had to be treated orthodontically to create acceptable occlusion. The treatment was carried out with fixed appliance and started after extraction of the four first permanent molars. No observable injury was recorded during the treatment.
牙本质发育不全是一种遗传性疾病，其特征是牙齿形成过程受到干扰。牙齿颜色从乳白色灰蓝色到类似琥珀色不等，伴有牙釉质裂开。在X线片上，髓腔明显闭塞是其特征性表现。本病例报告描述了一名患有牙本质发育不全的13岁男孩。高龋齿活性导致第一恒磨牙广泛龋坏。该男孩必须接受正畸治疗以建立可接受的咬合关系。治疗采用固定矫治器，在拔除四颗第一恒磨牙后开始。治疗期间未记录到明显损伤。
