Abstract
To determine the prevalence of posterior superior alveolar artery (PSAA) among sample of Egyptian population using cone beam computed tomographic images. The present study was performed as a retrospective analysis of data stored in Oral and Maxillofacial Radiology department, Faculty of Dentistry, Cairo University. Out of respect for patients' confidentiality, all personal information concerning the patients (except the gender and age) as well as the diagnostic cause of the CBCT scan was hidden. Out of 200 archived cone beam computed tomographic (CBCT) images of living non-pathological patients, 170 were conducted in the current study; 70 males and 100 females aged between 30-70 years. All the patients were scanned with preoperative cone beam computed tomography (CBCT) for The study was performed in Oral and Maxillofacial Radiology department, Faculty of Dentistry, Cairo University. Our results uncovered that PSAA was detected by 88% (163 out of 170) and was undetected by 11.9% (7 out of 170). The prevalence of PSAA needs thorough investigations to avoid its risk injury and further consequences while performing dental implants.
