The purpose of this study was to obtain data necessary for guiding students in the future by grasping which rate of error is made how much depending on a shooting technique in the filming of periapical radiograph. 14,402 films,which were instructed targeting students for the Department of Dental Hygiene at D Health College and S Health College, were analyzed. The following results were obtained by conducting questionnaire survey targeting 263 students who completed the shooting practice lesson of bisecting angle technique and paralleling technique. 1. In case of having shot with bisecting angle technique, the ratio of error was the highest in both maxillary and mandibular first molar. 2. In case of having shot with paralleling technique, the ratio of error was the highest in the maxillary bicuspid and the mandibular first molar. 3. As for ratio of error in light of a shooting technique, both bisecting angle technique and paralleling technique were indicated to be the highest in inaccuracy of film position. The bisecting angle technique was indicated to have the higher ratio of error compared to the paralleling technique. 4. As for ratio of error in light of the processing technique, both bisecting angle technique and paralleling technique were indicated to be the highest in dark image and light image. The bisecting angle technique was indicated to have the higher ratio of error compared to the paralleling technique. 5. Students were indicated to feel it to be most difficult for grasping the processing level in the film-developing process. As the above results, to reduce ratio of error given the periapical radiography, a method of reducing ratio of error given the periapical radiography is considered to be what correctly understands the morphological and anatomical structure inside the mouth and what acquires the shooting technique by filming several times with having enough time
