Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder that is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones that break (fracture) easily, bones that are not formed normally, and other problems. Signs and symptoms may range from mild to severe.

What is Type 2 dentinogenesis imperfecta?

Overview. Dentinogenesis imperfecta type 2 is a rare and severe form of dentinogenesis imperfecta, a condition that affects tooth development. People affected by the condition may have weak and discolored teeth. These problems can affect both primary (baby) teeth and permanent teeth.

What is a Distomolar?

A distomolar is a supernumerary tooth which is located distal to third molars. They appear more frequently in men than in women. Several theories had been suggested to explain this phenomenon with the “dental lamina hyperactivity theory” to be the most accepted. Supernumerary molars (distomolars) are usually impacted.
