[Micrographic aspect of mandibular osteoradionecrosis (author's transl)].

Fragments of the lower jaw from 42 patients with carcinoma of the oral cavity or oropharynx, and treated primarely with fraction radiotherapy, were excised for radiation osteonecrosis 6 month to 10 years after irradiations. The excised specimens are X-rayed before being coated with methylmetacrylate. They are then cut into thick sections along lines detailled on the X-ray films. The sections are trimmed to 80 microns and examined microradiographically. Two observations are sufficient to demonstrate destruction or reorganisation of the bone tissue. Reabsorption of unusual appearance is seen around the Haversian canals. The newly formed tissue resembles either embryonic bone matter, or lamellar tissue as seen in osteomyelitis.

[Functional rehabilitation of irradiated maxillary bones (author's transl)].

The teeth should be conserved before radiotherapy: --in patients with good buccodental hygiene the teeth are conserved and fluoride treatment instituted,--when hygiene is only moderate, the mandibular teeth outside of the treated area are left in place and fluoride treatment is also attempted. The crowns are conserved, and an attempt is even made in some cases to apply them, as for example on the canines.--when hygiene is inexistant, all the teeth are extracted. Following radiotherapy, the authors will restore a prosthesis two months after irradiation in long-standing edentulons patients, and after 6 months for patients who have recently become edentulons. They sometimes recommend conservative treatment and a fixed prosthesis when the social context is favourable.
