[SEM study of radiogenic caries].
The present SEH study could show that radiogenic caries is accompanied by morphological changes at the dentine-enamel junction. These changes appear as lacunar defects of up to 300 microns in size. This kind of defect was found in 28 of 32 teeth which were exposed to radiation of more than 40 Gy. In a control group with caries of the smooth surfaces no comparable results could be obtained.
