Dentinogenesis imperfecta is one of the most common autosomal dominant traits experienced in humans. It generally affects both the deciduous and permanent dentitions. There are 3 forms of dentinogenesis imperfecta that have been classified into type I (osteogenesis imperfecta associated), type II (hereditary opalescent dentin), and type III (Brandywine isolate opalescent dentin).1,2 The prevalence for all types of dentinogenesis imperfecta is approximately 1 per 8000 subjects. Early diagnosis and treatment are therefore, fundamental, aiming at obtaining a favourable prognosis since late intervention makes treatment more complex. This clinical report describes a treatment solution to the problems encountered by a dentinogenesis imperfecta patient with minimally invasive techniques.
