Abstract
This study compares the effects of fractionated 2400, 4800 and 7200 rad doses of Co-60 irradiation on the formed and developing teeth of the rats. The 7200 rad dosage was found to cause damage to both odontoblasts and ameloblasts of developing incisors but to spare previously formed molars.
摘要
本研究比较了2400拉德、4800拉德和7200拉德分次钴-60照射剂量对大鼠已形成和正在发育牙齿的影响。结果发现，7200拉德的剂量会对正在发育的切牙的成牙本质细胞和成釉细胞造成损伤，但不会影响先前形成的磨牙。
