Relationship between periapical lesions and sinus changes on multi-slice computed tomography sean.

Unlabelled: Differentiating orofacial odontogenic pain/disorders from pain/disorders associated with maxillary sinusitis is important to avoid unnecessary dentalprocedures and to properly refer patients to colleagues/dentists and vice versa.

Aim: To analyze the association between apical lesions and sinus changes and to evaluate the agreement between the diagnoses of an endodontist, a radiologist, an oral and maxillofacial surgeon, and an otolaryngologist.

Materials And Method: 385 axial, coronal, and sagittal MSCT scans were selected using an image archiving andcommunication system (PACS).
