HISTOPATHOLOGICAL CHANGES IN THE PERIODONTAL LIGAMENT AS A RISK FACTOR FOR MAXILLARY TUBEROSITY FRACTURES: ANOTHER POINT IN THE INFORMED CONSENT?

Resumen

Maxillary third molar extractions can lead to complications, particularly maxillary tuberosity fractures. While the periodontal ligament is essential for load distribution, histological evaluations of the periodontal ligament in relation to these fractures are notably absent from the literature. This report presents a case where a significant fracture occurred during a third molar extraction. Histopathological analysis of the specimen revealed marked tissue alterations, including free and attached concentric calcifications and pronounced cementum irregularities. These findings, indicating a localized disruption of the periodontal ligament integrity, were not detectable through standard preoperative imaging. Therefore, these histological changes may represent a novel and previously undocumented risk factor. This case underscores the importance of a thorough preoperative evaluation and transparent risk communication during the informed consent process. Further studies are warranted to validate these findings and understand their prevalence.
