Pulp canal obliteration after Le Fort I osteotomy
Endodontics & Dental Traumatology
|December 1, 1989
Summary
Pulp canal obliteration (PCO) occurred in 2.3% of teeth after Le Fort I osteotomy. Teeth near vertical cuts were more affected, suggesting blood supply changes may cause PCO.
Area of Science:
- Oral and Maxillofacial Surgery
- Endodontics
- Orthodontics
Background:
- Le Fort I osteotomy is used for dentofacial anomaly correction.
- Pulp canal obliteration (PCO) is a potential complication following dental surgery.
- Understanding PCO development is crucial for long-term dental health.
Purpose of the Study:
- To determine the frequency of PCO after Le Fort I osteotomy.
- To identify pre- and peroperative factors influencing PCO development.
- To assess the long-term implications of PCO.
Main Methods:
- Longitudinal study of 51 patients.
- Follow-up of 617 maxillary teeth for an average of 28 months.
- Analysis of periapical radiographs and surgical factors.
Main Results:
- PCO developed in 14 (2.3%) of 617 teeth.
- Canines (6.0%) and premolars (4.4%) showed the highest PCO frequency.
- PCO was significantly more frequent adjacent to vertical interdental osteotomies (p < 0.0001).
Conclusions:
- Le Fort I osteotomy can lead to PCO, particularly in canines and premolars.
- Vertical osteotomy sites are associated with a higher risk of PCO.
- Long-term monitoring is recommended due to potential delayed pulp necrosis.
