<p> Abstract In order to understand and participate in community healthcare activities, trainee dentists have engaged in school dental checkups since 2006 as part of the training curriculum in Tokushima University Hospital. They have performed dental checkups at primary, middle, high and other schools. We have conducted a questionnaire survey of trainee dentists and school dentists after all planned activities were completed. To upgrade the quality of examinations, practical measures based on the questionnaire results were gradually introduced. Trainee dentists were taught the objectives of examinations, trained to standardize diagnostic criteria for caries using extracted teeth, and examined each other including recording actual examination outcomes, before they went to schools. In this study, questionnaire data from 2006 to 2015 were summarized to evaluate this training curriculum.</p><p> On average for the 10 years, 91.5% of trainee dentists felt that the training had a useful influence, 95.6% of school dentists also recognized the value of school dental checkups in the post-graduate clinical training course for the reasons that the many examinations improved their skills and they learned about the students’ oral situations. Trainee dentists deeply understood the meaning of this training with lecture, standardization of diagnostic criteria and mutual examination. In contrast, the above-cited preliminary training showed no significant change in their knowledge and skills. Most of the school dentists treated this training as a good opportunity for trainee dentists to experience health-promoting activities, and so more school dentists have joined the program. The analysis results suggest that dental checkups at school are effective for trainee dentists to understand community healthcare and are appreciated by both trainee dentists and school dentists.</p>
