In the cases of cancer diagnosis in oral cavity, radiotherapy has a particular interest for the dentist as an instrument for tumor treatment therapy which main objective is to eradicate these tumors with the minimum of adverse effects. On of the consecuences of the radiotherapy is osteoradionecrosis which is an injure laying in post-irradiated tissues where there is a serious hypoxic engagement. The tumors radiotherapy protocols laying on floor of the mouth, tongue and neck are highly aggressive, this increases the possibilities of causing bone necrosis ( maxillary  bones) and surround tissues. There is, for patients presenting osteoradionecrosis, a treatment which accelerates the healing process and improves the antibiotics bio-availability at a local level named hyperbaric oxygenation which acts raising oxygenation in hypoxic tissues. The hyperbaric oxygen treatment consist in administrating a 100% oxygen to an individual who has previously been exposed to a environmental pressure over 1,3 absolute atmospheres, this can be achieved in sealed room named hyperbaric chamber. Through this method and alongside with other medical surgical techniques several severe affections can be treated. The hyperbaric oxygen or oxygen administrated under a pressure environment work as an actual medicine (drug) producing different answers according to the dose and time administration.
