Histopathology of the Dental Pulp of Dogs Following Exposure

Abstract
This report deals with the histopathological responses which were observed in the pulp of dogs'' teeth following exposure for periods ranging from 7-47 days. The pulp tissues exhibited gradations in inflammatory response from mild chronic to acute. These conditions were characterized by necrosis, abscess formation, vascular exudation, granulation and fibro-sis. Introduction of dentin spicules into the pulp tissues appears to stimulate the formation of a calcified tissue resembling osteo-dentin.
