Osteogenesis imperfecta (OI) is a rare inherited disorder that causes bones to break easily.
Individuals with osteogenesis imperfecta break bones often and may have other problems,
including hearing loss and pain and difficulty getting around. People with moderate to severe
OI may also be diagnosed with dentinogenesis imperfecta (DI). DI is characterized by grey or
brown teeth that may chip and wear down and break easily. People with DI may also have skull
and neck defects. These patients may have severe teeth misalignment resulting in clinically
significant chewing problems. Teeth misalignment in OI is very hard to treat because of the
quality and quantity of bone. The overall goal of this study is to improve dental health to
improve the quality of life of people with OI.

Investigators will look at dental health in people with OI and will describe teeth
misalignment and head and neck defects in individuals with moderate to severe Osteogenesis
Imperfecta (OI).

Investigators will look at results from the Longitudinal study of OI to complete the study
evaluations. Several x-rays will be performed for this study. Participants will have a 3D
scan of the mouth and a Cone Beam CT scan of the jaw at a baseline visit and at 3 years after
the baseline visit. These study visits can be at the same time as the Longitudinal Study of
OI study visits.

Inclusion Criteria:

- Males and females with Clinical diagnosis of OI other than OI type I

- Individuals 10 years or older

- Participant of the Brittle Bone Disease (BBD) Longitudinal Study (7701)

Exclusion Criteria:

- Individuals who cannot be correctly positioned for valid radiographic analysis (e.g.,
due to severe scoliosis or short neck secondary to basilar invagination)

- Women who are pregnant
