Objectives. The aim of the study is to detect the prevalence and the characteristics of infraorbital canal and Haller’s cells on panoramic radiography of edentulous patients. Methods. The study group comprised 291 panoramic radiographs of edentulous patients. Radiographs were interpreted for the visibility and characteristics of infraorbital canal and Haller’s cells. For classification of infraorbital canal, a method based on the image characteristics of the border of the canal (Types I, II, and III) was used. Haller’s cells were grouped according to the number and the shape of loculations. Results. Infraorbital canal was observed in 246 (84.6%) radiographs. The most prevalent of the observed canals were Type III for both sides (39.9 % for right and 32.3% for left side). The visibility of Haller’s cells was 23.7%. The frequencies of Haller’s cells’ visibility were approximately equal for both genders. There is no significant difference between genders for the visibility of infraorbital canal and Haller’s cells. Conclusions. The surgeons, implantologists, and radiologists should take into consideration infraorbital canal and Haller’s cell for planning implant surgery of maxillary anterior region and undefined orofacial pain for edentulous patients.
