This is a DVD of a lecture by Dr. Hiramatsu, hosted by the Japanese Association of Visiting Dentistry. There are no materials included. Dr. Hiramatsu is active in oral care and is also well-versed in swallowing and eating. VF videos are shown during the lecture, but they are not included due to privacy concerns, and it's a shame that some explanations are incomplete, but the content is substantial and I learned a lot. The condition is based on subjective judgment, and please understand that this is a used item.
