title: [External-internal tooth resorption as a delayed effect of thorium X (Ra224)].
abstract: Twenty-five years after treatment with thorium X (Ra 224), we found unusual, multifocal dental resorptions in four patients. The results of gamma-spectrographic, auto-radiographic and histological examinations suggest that Ra 224 caused such changes.
