44 y/o female w history squamous cell carcinoma soft pallet. Received XRT about a year ago. Last month underwent tooth extraction of one of her molars. She received the Marx protocol...10 dives prior to the tooth extraction then 10 dives post. She has done well. She completed her last dive about 2 weeks ago. She calls now saying she may need a root canal on one of her other teeth.
My question: does she need more HBO2 treatments post root canal and is there any data on how long into the future the effects of the Marx protocol will last in patients like this?
