[Structure and vascularization of the dental pulp in horse incisors]. 1981

A Barasa, and S Dazia, and B Canavese, and R Modica

The dental pulp of 34 horses aged between 4 months and 20 years has been studied on India ink injected and on paraffin embedded specimens. The pulp dimensions of the first and especially of the second dentition decrease with age. This reduction is accompanied by pronounced changes of structure; the mucous connective tissue becomes a dense, irregular connective tissue. The vessels are numerous and make a network particularly rich at the margins of the pulp; they diminish with advancing age. The reduction of the pulp volume and the regression of its vascular network are particularly pronounced at the crown level whose pulp cavity is progressively filled with secondary dentin. The regression of the vascular network precedes the reduction of the pulp volume.
