Structural, Ultrastructural, Microradiographic, and Electron-probe Studies of an Unusual Case of Regional Odontodysplasia

Abstract

Structural, ultrastructural, microradiographic, and electron microprobe studies of an unusual case of odontodysplasia were performed. Two cusps were absent from one molar. Normal prismatic enamel and mantle dentin were present on the two others. The dentinal mass resembled osteodentin. The mineral content of enamel and dentin was decreased compared to that of the controls.
