Lymphatic Vessels of the Dental Pulp in Dogs

¹ Department of Anatomy, School of Medicine, University of Southern California, Los Angeles, California 90033

Lymphatic vessels of the pulp were traced in the teeth of dogs. At the coronal surface the lymph capillaries originated as blind beginninigs in the pulp proper near the zone of Weil, whereas they are found adjacent to the odonttoblastic layer on the lateral surfaces. These capillaries emptied into collecting lymph vessels that coursed apically to exit through the apical foramens to finally drain into the alveolar lymphatic vessel.
