The morphostructural changes in pulp and periodontium of abutment teeth in fixed prosthesis were experimentally studied using the method of vital amputation and application of Pulpotec over the period of 1,3 months. Compensatory and proliferative changes involving formation of apically directed fibrosis connective tissue were detected in the pulp. No sings of inflammation were revealed. The periodontium showed an increase in collagen fibers, a decrease in the cellular components as compared to the reference (control) teeth. Increased calcification of cementum and bone matrix was also observed. All these modifications are due to changes in the mineral metabolism, and adaptive restructuring of PDL, caused by increased functional load on the abutment teeth coated with cast crowns.
