Uninherited dentinogenesis imperfecta

Area of Science:

• Genetics
• Oral Medicine
• Orthopedics

Background:

• Dentinogenesis imperfecta (DI) is a rare hereditary disorder affecting dentin formation in both primary and permanent teeth.
• DI can be associated with osteogenesis imperfecta (OI), a systemic bone disorder, though often attributed to different genes.
• The genetic relationship and clinical presentation of DI and OI require further investigation.

Purpose of the Study:

• To report a case of a 19-year-old man with a late-onset, atypical form of osteogenesis imperfecta.
• To explore the potential association between dentinogenesis imperfecta and osteogenesis imperfecta in this patient.
• To discuss the diagnostic and etiological implications of dental manifestations preceding bone disease.

Main Methods:

• Clinical case presentation and review.
• Analysis of patient's medical history, including diagnosis of dentinogenesis imperfecta at age 6.
• Observation of the subsequent development of atypical osteogenesis imperfecta at age 17.

Main Results:

• A 19-year-old male presented with dentinogenesis imperfecta diagnosed in childhood and subsequently developed an atypical form of osteogenesis imperfecta.
• The patient's family history showed no apparent signs of dentinogenesis imperfecta, making the case atypical.
• Dental abnormalities in dentinogenesis imperfecta may serve as early indicators for the development of osteogenesis imperfecta.

Conclusions:

• The co-occurrence of dentinogenesis imperfecta and osteogenesis imperfecta in this patient suggests a potential, albeit complex, genetic or clinical link.
• Atypical presentations of osteogenesis imperfecta, particularly in the absence of a clear family history of DI, warrant thorough dental evaluation.
• Dental manifestations can be crucial in the early diagnosis and management of systemic skeletal disorders like osteogenesis imperfecta.
