Osteogenesis imperfecta type III : oral, craniofacial characteristics and atypical radiographic findings oral

subject

description

Osteogenesis imperfecta (OI) is a disease characterized by decreased bone mineral density, causing susceptibility to bone fractures by mild trauma and bone deformities. The aim of this study was to describe an osteogenesis imperfecta type III clinical case, its craniofacial and oral changes as well as its atypical radiographic findings. An eighteen-year-old, male patient diagnosed with osteogenesis imperfecta type III was referred for dental evaluation; the clinical examination showed the craniofacial and oral changes of the disease such as triangular face, class III malocclusion, anterior open bite and posterior crossbite, dentinogenesis imperfecta presenting amber discoloration. The radiographic examination revealed teeth with pulp chamber obliteration and root canals, however unusual findings were also observed such as: bilateral increase of the mandibular canals and preservation of the pulp chamber and third molar root canals. Our findings show that is essential an adequate knowledge of anatomy, a careful anamnestic evaluation and a complete radiological evaluation of the patient with OI. Key words:Dental anomalies, developmental disability, rare disorders.
