Pulpal and radicular response to maxillary osteotomy in monkeys
Oral Surgery, Oral Medicine, and Oral Pathology
|June 1, 1982
Summary
Total maxillary osteotomy negatively impacts tooth pulp and root health in monkeys. Histological examination revealed significant cellular and circulatory changes in the majority of teeth, even with collateral circulation.
Area of Science:
- Oral surgery
- Dental histology
- Primate research
Background:
- Maxillary osteotomy is a surgical procedure involving bone removal in the upper jaw.
- Understanding the effects of such procedures on dental tissues is crucial for patient outcomes.
Purpose of the Study:
- To investigate the pulpal and radicular responses following total maxillary osteotomy.
- To assess histological changes in dental tissues after this surgical intervention.
Main Methods:
- Total maxillary osteotomy was performed on four adult Macaca irus monkeys.
- A 150-day postsurgical observation period was maintained.
- Maxillary tissue blocks containing teeth were harvested and examined histologically.
Main Results:
- The majority of teeth in experimental animals exhibited cellular and circulatory pathologic changes in the pulp.
- These pulpal changes were observed despite the presence of collateral circulation.
Conclusions:
- Total maxillary osteotomy can lead to significant pulpal and radicular pathology.
- The findings highlight potential risks to dental viability after extensive maxillary surgery.
