Morphological Study on the Gubernacular Canal of Crab-eating Monkeys

(Macaca fascicularis) at Deciduous Dentition Stage with Sp e c i a l Reference to its Facio-lingual View

Abstract

Morphological studies were carried out on the g ubernacular canal. This canal starts from the alveolar bone of the lingual side of the deciduous tooth and ends at the bony crypt of the succeeding permanent tooth. The plastic-embedded ground sections, cut at the facio-lingual direction, were examined microscopically. They were obtained from the dried skulls of crab-eating monkeys which were estimated to be at the stage of deciduous dentition.
The results were obtained as follows
