Multiple external-internal resorptions are infrequent and are related to a variety of etiological factors. Thorium X (224Ra) is believed to cause the dental resorptive changes observed in 2 patients who had received a series of injections each containing 8 to 70 muCi of 224Ra 25 years previously.
多发性内外吸收并不常见,且与多种病因相关。钍X(镭-224)被认为是导致2例患者出现牙齿吸收变化的原因,这2例患者在25年前接受了一系列注射,每次注射含8至70微居里的镭-224。
