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.
摘要
在用钍X（镭224）治疗25年后，我们在4名患者中发现了异常的多灶性牙齿吸收。伽马能谱分析、放射自显影和组织学检查结果表明，镭224导致了这些变化。
