Aim: The aim of this study was to evaluate the quality of digital periapical radiographs obtained using bisecting angle technique by 3rd grade dental students, who were theoretically taught on paralleling and bisecting angle techniques and had the practical experience only for the paralleling technique on dental phantom models. Materials and Methods:The quality digital periapical radiographs, taken with photostimulable phosphor plates (PSPs) by 3rd year dental students during the initial examination, was evaluated.The type of the teeth, errors on the radiographs related with angulation of the tube head, placement and exposure of the film, and the radiographs, which needed repetition, were recorded.Results: Overall 288 digital periapical radiographs (53 maxillary anterior, 26 mandibular anterior, 109 maxillary posterior, 100 mandibular posterior) were evaluated.The percentage of radiographs that needed repetition was found as 13.5%.The percentage of positioning errors related to the visibility of the apex was 20,1%.The percentage of the presence of conecut was 28,1%.Overall rate of angulation error was found to be 36,8%.Conclusions: The need for repetition of periapical radiographs taken by 3rd grade dental students seems to be high.Evaluation of the clinical performance of the dental students is needed to identify the deficiencies in teaching/learning process, and for improvement of the dentomaxillofacial radiology curriculum and provision of patient safety.Dental curriculum should be revised, so that the practical courses including bisecting angle technique as well as paralleling technique was taught both theoretically and practically.
