I know this is an older post and I don't know if you have come up with a solution but, EarIC hit the nail on the head. Never use a system that attaches to your body. There is just too much movement and the light source moves as well. It can actually make some people sick watching the video.
I specialize in developing systems for Dentists and oral surgerns. I worked with 3i for 10 years and understand the special needs of capturing a dental procedure.
I suggest an auto clutching arm ceiling mounted with a POV camera that auto focuses and auto adjusts for irus etc. I have desigened many of these systems and would love to speak with you.
