ra·di·a·tion car·ies

caries of the cervical regions of the teeth, incisal edges, and cusp tips secondary to xerostomia induced by radiation therapy to the head and neck.

radiation caries

tooth decay triggered by exposure of the head to ionizing radiation. It especially affects the cementoenamel junction and the coronal root area. Radiation makes the teeth more susceptible to caries by decreasing salivation, reducing the vitality of dental tissues, and altering oral bacteria. Radiation caries is often a side effect of radiation therapy for oral malignancies. See also dental caries.
