Purpose:
To study the heritable character and explore the prosthodontic treatment of opalescent dentin, also known as dentinogenesis imperfecta type II(DGI-II).
Methods:
Pedigree analysis was performed in the family members of patients with DGI-II found in Shanghai. The proband was treated with ceramometal restorations and investigated the treatment status of the DGI-II affected individuals in the family.
Results:
Five sequential generations with DGI-II were found in this family. The prevalence of later generation was approximately 50%. The rate of prosthodontic treatment was 90% nearly, including ceramometal restorations in the most of the patients and removable partial dentures in the others. The esthetic and mastication functions of the patients were good after treatment.
Conclusions:
DGI-II showed a autosomal dominant pattern of inheritance. Ceramaometal restorations can prevent the affected teeth from abrasive and fracture, and also can help rehabilitate the esthetic and mastication functions of the teeth.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
