Body
Objectives: The aim of this study was to describe the prevalence of the anatomic variant cystlike
lesions in the mandibular condyle in digital panoramic radiographs in comparison to its
prevalence in panoramic film radiographs.
Methods: This study was approved by the Institutional Review Board for ethics in medical
research involving human subjects. We retrospectively screened digital and filmed based panoramic
radiographs which were conducted in our Oral Maxillofacial Imaging unit in the Department
of Oral Medicine, at the Hebrew University-Hadassah School of Dental Medicine. Screening
was done by 4 different observers who were calibrated prior to the study. Screening was
aimed to diagnose the presence of cyst-like lesions in the mandibular condyle and describe its
size and shape. Other parameters including gender and age were collected for each radiograph.
Results: We screened 500 digital and 500 filmed based panoramic radiographs. We found higher
prevalence of cyst-like lesions than documented in the literature. Prevalence of the cyst-like
lesions in digital imaging was slightly higher than the prevalence in film-based radiograph.
Conclusion: This anatomic variant should be recognized due to its high prevalence especially
when using digital panoramic imaging.
