The Training and Safety Lecture Committee of the Japan Society for Laser Dentistry held the 4th educational seminar at the Health Sciences University of Hokkaido in 2016. This seminar was aimed at the first undergraduate training of the academic society, and combined lectures and hands-on training for the 5th grade of the dental school of the university. After completing the seminar, we conducted a questionnaire survey on the degree of understanding of the students and their interest in the laser. Forty-nine valid answers were collected （collection rate 100%）. The degree of comprehension of both lectures and practical training was 90% or more, and about 90% of students answered that they were interested in the clinical application of lasers in the future. Based on the results, the seminar was satisfying for the students, suggesting the effectiveness of undergraduate training in laser dentistry.
