Abstract : Dentinogenesis imperfecta is an autosomal dominant inheritable disorder affecting an estimated 1 in 6,000 to 8,000 people. It is usually found as opalescent blue-gray or yellow-brown dentin of deciduous teeth. The enamel is prone to exfoliation or fracture and the dentin promptly wears, resulting in pulpitis or apical periodontitis. As pulp obliteration is typically too severe for conventional root canal treatment, extraction is often indicated. This case report describes endodontic treatments to preserve two non-vital permanent teeth of a patient with dentinogenesis imperfecta using a microscope and cone beam computed tomography.
