Dental hygienists need to understand basic anatomy in periapical radiographs to gather information and support imaging in oral health care. However, to date, few studies have analyzed how hands-on periapical radiography training (HPRT) enhances understanding of imaging anatomy for these students. The degree of knowledge in imaging anatomy required for second-year students was assessed using an objective test before the HPRT. For the hands-on training, the students were divided into two groups, the lecture only group and the lecture and hands-on training group. After the hands-on training, an objective test and subjective evaluation by a questionnaire were conducted. In the hands-on group, all the objective items of the students' knowledge of anatomy improved. The rate of increase was significantly greater than that for the group that had only the lecture. In the post-hands-on training questionnaire, the subjective evaluation was high except for the item related to willingness to learn more. This study showed that hands-on training was superior to lectures alone in understanding imaging anatomy. In the future, it is necessary to create classes that will motivate students to learn more about oral radiology. (J Osaka Dent Univ 2023; 57: 147-152)
