Dental Caries
  • It was suggested that the scalloping is beneficial for the mechanical properties of teeth as it reinforces the anchor between enamel and dentine. [4] However, the teeth are not more susceptible to dental caries than normal ones.[en.wikipedia.org]

Eruptions
  • The pulp chambers are initially larger than normal prior and immediately after tooth eruption, and then progressively close down to become almost obliterated by abnormal dentin formation. Roots are short and thin.[uniprot.org]

Prognosis

  • His prognosis is somewhat guarded because of his predisposition to fractures.DISCUSSIONOsteogenesis imperfecta is an inherited mutation in one of two genetic loci coding for type I collagen—COL1A1and COL1A2.[osteodocjuan85.blogspot.com]

Etiology
