I think you can just list them. I'm not really sure it makes a difference. As far as writing golf or badminton... it's a stretch but I would include it. It is more hand eye coordination so if you are going to add that into the section, try to find other things on a much smaller scale, such as painting, models, playing an instrument...that is truly manual dexterity. So if you are going to put golf, make sure to have some of those little intricate activities too... They would better relate to dentistry and working with confined areas.
I wouldn't mention the Kaplan course. That doesn't really matter.
