Objectives: This study was carried out in order to obtain basic data for students` efficient acquirement and instruction of radiography technology in the future by surveying dental hygiene students` recognition of periapical radiography.
Methods: This study carried out a questionnaire survey targeting dental hygiene students from December 2009 to December 2010, and obtained the following results.
Results: 1. As a result of examining recognition on periapical radiography, the bisecting angle technique was indicated to be averagely 3.84±0.566 points. The paralleling technique was indicated to be 2.66±0.701 points. 2. As a result of examining about problems given the bisecting angle technique, what had been most difficult given the bisecting angle technique was indicated to be the highest in cone positioning with 34.2%. The most difficulty given deciding on the X-ray vertical-angel irradiation direction was indicated to be the highest with 66.9% in adjusting the cone direction on the virtual bisector. 3. As a result of examining about problems given the paralleling technique, what had been most difficult in the process of the paralleling technique was indicated to be the highest with 56.7% in fixing the film immobilization device inside the mouth.
Conclusions: Examining the above results, it is considered that there is a need of understanding morphological and anatomical structure inside the mouth in order to reduce the mistake rate given the periapical radiography, and that it is important to increase skill level by repetitively shooting several times with having enough time.
