Three-dimensional Changes in Direction and Interrelationships among Enamel Prisms in the Dog Tooth

Abstract

Summary. This study describes the three-dimensional features of enamel prisms and their arrangement in dog teeth. Tangential semithin sections of demineralized tooth germ were serially cut from the enamel surface to the enamel-dentin junction. Straight rows of enamel prisms parallel or perpendicular to the meridian were selected at the enamel-dentin junction; these prisms were reconstructed from micrographs with a personal computer. © 1992, International Society of Histology and Cytology.
