ABSTRACT
The authors review the studies describing dental changes after radiotherapy or curietherapy of the cervicofacial region published over the last 50 years. They discuss more particularly: --direct and indirect effects on the teeth,--lesions of the salivary glands,--dental lesions,--fluoride prophylaxis for dental lesions after irradiation.

Before antitumoral facial irradiation, those teeth that cannot be conserved for a sufficiently long post-irradiation period of at least two years should be extracted. Teeth that are less affected, in patients given palliative treatment and in whom the prognosis is better, can be conserved. The conserved teeth are protected from destruction by the application of a fluoride gel. Dental reconstruction is ensured by the conventional methods, including the fixed prosthesis. The arches can be restored with atraumatic fixed prostheses but prudence is required. If extraction is necessary, a strict procedure must be employed and sufficient antibiotic treatment prescribed.

An analysis of delayed action cell immunology tests involved 300 patients suffering from stomatological cancers. The tests used, tuberculine, candidine, varidase and DNCB have no particular value as far as discovering the size of the tumour, the quality of eradicating treatment or its progress. On the other hand, bias in the same direction and, even more, variations in the direction of immunity in the course of evolution seem to be a reflection of the patient's immune defence potential. This immune defence potential which can be roughly assessed in this way dose not seem to be reduced by chemotherapy or increased by immunotherapy, at least judging by the criteria used.
