Electron Microscopic Aspects of Teeth taken from the Ovarian Dermoid Cysts

Abstract

1. Teeth taken from the ovarian dermoid cyst resemble those of the oral derivation in respect of macroscopic morphology, lustre, hardness and optical microscopic findings.
However, when studied under the electron microscope the following interesting features are revealed.
2. Enamel is imperfectly formed and, for this reason, apatite crystals which form an important and principal constituent of enamel cannot be morphologically ascertainable.
Masses of amorphous calcium that are raised and smooth in outer appearance are found diffusedly here and there in enamel.
3. Dentin is also structurally imperfect. The imperfectly formed matrix and tubules give characteristically imperfect images.
4. Because of defective formation of dentin and cementum, the collagenous fibers are found to lack cross striations that are characteristic of them.
