Abstract:
By using replica cast SEM method, the vascular architecture of the dental pulp of rat incisors was studied. The characteristics of the vascular architecture are as follows:1. The axis of the dental pulp is occupied by the central vascular bundle, which consists of 10 to 20 arterioles and 8 to 12 venules.2. The arterioles (30-50?m in diameter) and the venules (50-80?m in diameter) located in the central bundles are arranged parallely in a relatively long distance as a countercurrent system. The longest distance is about 12 mm.3. Each arteriole of the central vascular bundle supplies an independent area of the dentin of the tooth. The territory of an arteriole is about 700 to 1400 ?m in length.4. The arteriole of the central bundle breaks up into capillaries (4～6?m in diameter) which are mainly distributed over the odontblast area and form a complex 3-dimensional plexus.
