Abstract: Osteogenesis imperfecta (OI), or brittle bone disease, characterized by bone fragility and susceptibility to fracture, is a group of heritable disorders of connective tissue. The incidence at birth is 1∶10000-1∶20000. OI has multiple secondary features, including blue sclerae, dentinogenesis imperfecta (DGI), hearing loss, and so on. In this paper, we reported a case of 24-year-old boy, with a chief complaint of tooth fracture and pain. On the grounds of history taken, clinical examination, radiological examination, and genetic testing, we came to a conclusion of OI with dentinogenesis imperfecta type Ⅰ.

Key words: dentinogenesis imperfecta, dentinogenesis imperfecta type Ⅰ, osteogenesis imperfecta, P3H1 gene
