The effect of cobalt-60 teletherapy on the pulps of restored teeth of monkeys was studied. Gold crowns and amalgam and composite resin restorations were placed in 28 teeth of two Macaca speciosa monkeys. One monkey then received cobalt-60 radiation to both maxillary and mandibular teeth and bones, with a total dose of 7,600 rads. Decalcified semiserial paraffin sections, 7 mum thick, of the teeth and supporting tissues were prepared and stained with hematoxylin and eosin. Microscopically, there was no discernible difference between the irradiated and the non-irradiated pulps.
研究了钴-60远距离治疗对猴子修复牙齿牙髓的影响。在两只戴帽叶猴的28颗牙齿上进行了金冠、汞合金和复合树脂修复。然后,对其中一只猴子的上颌和下颌牙齿及骨骼进行钴-60辐射,总剂量为7600拉德。制备了牙齿和支持组织的7微米厚的脱钙半连续石蜡切片,并用苏木精和伊红染色。显微镜下,照射牙髓与未照射牙髓之间没有明显差异。
