「Introduction」Various methods and techniques1-7) have been used to study the blood vessels of the oral tissues and organs of man, as well as those of experimental animals. Although numerous studies have demonstrated the arrangement of the vascular network of the oral epithelial papillae, they represented the vascular network only in two-dimentions. A detailed analysis of the three-dimentional vascular arrangement in the oral epithelial papillae has not yet been reported. The purpose of this study is to describe the various types of networks distributed in the oral epithelial papilae of the dog in threedimentions using the injection of low-viscosity resin into the blood vessels, and then examining them with a scanning electron microscope (SEM). 「Materials and Methods」Five adult dogs were anesthetized with sodium pentobarbital (0.5ml/kg) and the bilateral common carotid arteries were cannulated. A sufficient amount of Ringer's saline solution was perfused into the arteries until from the changes in color, the jugular veins appeared to be cleared of blood.
