Laser treatments have become widespread in general practice of dental treatments. But few undergraduate students have real experience with laser irradiation during their student years. To undergo laser irradiation, we tried to apply the practice of laser irradiation to the current practice of operative dentistry for fourth-year students. The students were divided into 20 groups, and each group received basic lectures on the principle of the carbon dioxide laser, and they were shown steps to handle the laser instruments prior to practice of laser irradiation. Each student irradiated a carbon dioxide laser to white meat, and subsequently, a questionnaire was completed. The questionnaire showed that a majority of the students were not able to understand the biological mechanisms of the laser in detail, but this practice aroused their interest in laser treatments and gave them incentive to study laser mechanisms. These results suggested that laser practice carried out by undergraduate students stimulated their motivation and had educational effectiveness.
