Student selection and Data collection
In this prospective, randomized study, we aimed to evaluate the effectiveness of training for physicians (men and women), without prerequisites, with courses taught by a single instructor and evaluator. Six face-to-face courses were held, from July 2020 to July 2021. In the courses we evaluated 56 students, with a workload of 8 hours per course, with small breaks, with groups of up to ten students. Before starting the course, the students filled in questionnaires with informed consent and personal data and at the end of the course they answered another questionnaire regarding the effectiveness of the course.At the end of the course, the instructor individually evaluated the silicone molds of each student.
