Pulpal and radicular response to maxillary osteotomy in monkeys.
The purpose of this study was to examine the pulpal and radicular response to total maxillary osteotomy. The osteotomy was performed on four adult Macaca irus monkeys. Monkeys were killed after a postsurgical observation period of 150 days. Tissue blocks of the maxilla with teeth were cut and examined histologically. The pulp of the majority of the teeth from experimental animals showed cellular and circulatory pathologic changes, even in the presence of collateral circulation.
