I can't say what the recommended time frame is for patients having extractions post last HBO treatment. If the oral surgeon and the hyperbaric physician are concerned about the down time and the patient has established ORN then the 30/10 protocol may be an option for you? Honestly, I can not offer much more info about this but I have sent your question to my medical director to see what she thinks.
