Abstract
Dentinogenesis Imperfecta (D. I. ) is a localized form of mesodermal dysplasia affecting the dentin with involvement of both the primary and permanent teeth. Clinically, the color of the teeth is translucent gray with an opalescent sheen. Attrition is frequently rapid and severe, and the affected teeth may become abscessed.
The findings in a 4-year-old girl patient affected with D. I. with impacted supernumerary teeth, were as follows.
1) Sever attrition in all deciduous teeth. Over denture type removable space maintainer was inserted after the restoration with metal crowns on those teeth affected.
2) Cross bite between the upper and lower central permanent incisors caused gingival recession.
3) Radiological and histopathological findings of the impacted supernumerary teeth in upper jaw showed the characteristics of dentinogenesis imperfecta.
4) Upper central permanent incisors were labially inclined with the finger spring soldered to the lingual arch in the upper dentition.
