Abstract Clinical competence assessment by dental hygienists (CA by DH) was tried and verified in addition to such an assessment by an instructor dentist (CA) employed in Niigata university hospital as a formative assessment for trainee dentists. Twenty-two trainee dentists participated after being given an explanation concerning regulations such as the judgement of acceptance with a Yes/No checklist or six evaluation items on “CA” and “CA by DH”. Passing score in each “CA” on conservative, prosthodontic treatments and oral surgery was mandatory, and striving to take “CA by DH” with a procedure that would need the assistance of a DH was explained to the participants. Furthermore, the participants were asked to complete questionnaire surveys on both exams. The results of 16 for “CA”, 22 for “CA by DH” and 22 and 21 of answers for each questionnaire, respectively, were collected and analyzed. The average number of “CA” performed was 1.3 and the passing rate at the first exam was 69.3%. “CA by DH” was processed on conservative and prosthodontic dentistry, and a passing rate of 63.6% was shown. Failure concerning the procedures based on diagnosis or material handlings in the proper manner tended to be reasons for disqualification of “CA”. Disqualification of “CA by DH” tended to be related to preparation and consideration for the assistant. It appeared that view points for evaluation items differed depending on the occupation. There were some disqualifications with multiple failures of evaluation items in both exams but it was difficult to determine the correlation between the procedures and evaluation items within the present survey. However, the questionnaire surveys received many affirmative answers to “CA” and “CA by DH”. It is suggested that “CA by DH” could be useful to assess the clinical competence of trainee dentist, although further improvement is needed.

 Abstract In this study, an experimental training program using two ICT tools (Google Classroom and Zoom) was conducted for trainee dentists assigned to a small-scale (four people) training group who were unable to participate in patient practice and sometimes had to receive remote training, due to the COVID-19 pandemic.

 In Google Classroom, which is a learning management system, the instructor dentist uploaded the tasks to be taught and schedules, and the trainee dentists uploaded daily learning outcomes in an electronic file.

 In addition, Zoom, which is a video conferencing system, was used for morning meetings, final meetings, and presentations on learning outcomes during the remote training period.

 A questionnaire and interview with four trainee dentists and four dental clinical instructors were conducted to survey the efficacy of this experimental training program.

 By using Google Classroom, trainee dentists were able to understand the overall picture of what was to be learned in the program and grasp the progress of the learning outcomes. In addition, timely feedback on learning outcomes uploaded by the dental clinical instructor motivated the trainee dentists to learn.

 On the other hand, the daily morning meetings, final meetings, and learning outcome presentations by Zoom encouraged the trainee dentists to maintain a regular lifestyle and continuously communicate between trainee dentists and dental clinical instructors, even during the remote training period.

 Abstract We investigated the annual number of lecture hours on infection control among students, clinical trainees, clinical residents, and hospital staff and surveyed the occupational exposure (needlestick and cut injuries, and exposure to blood and body fluids) in 17 Japanese private dental schools from April 2012 to March 2017.

 As a result, the annual number of lecture hours on infection control among all dental personnel showed no statistically significant difference in all positions from fiscal years 2012 to 2016. Meanwhile, the number of cases of occupational exposure in 17 dental colleges and universities declined. By occupational category, the number of cases of occupational exposure among clinical trainees declined ; and those among clinical residents and hospital staff including dentists, dental hygienists, nurses, and others showed no notable changes. A negative correlation between the annual number of lecture hours on infection control and the number of cases of occupational exposure to blood and body fluids among clinical trainees was found (ρ=−0.40).

 Based on these results, we suggest the necessity of sharing information and setting an appropriate annual number of lecture hours on infection control in 17 dental colleges and universities through the Council of Infection Control in Japanese private dental school hospitals. Moreover, it is necessary to investigate the methodologies, contents, and learning levels of infection control measures and survey details of occupational exposure, such as their cause levels of injuries, and aftercare.
