Dentinogenesis imperfecta (DI) is a type of dentin dysplasia that affects the dentin structure of one or both dentitions, which may be classified in three types. The aim of this report was to show the clinical and radiographic features of the four cases of DI in the same family group. Five brothers were checked clinically and radiographically. Two individuals were diagnosed, by their phenotypic features and medical history, with DI type I; two of them with DI type II and one case without signs of DI. It is important to know the features of dentinogenesis imperfecta to perform a comprehensive dental care, including the right diagnosis and an effective treatment plan.
