title: [Fluoride content of teeth following treatment with Zircate paste].
abstract: We extracted the four lower incisive teeth 41, 42 and 31, 32 of ten patients in age of 50-73 years. The indication was a profound marginal parodontopathy. Before extraction the incisors of the right side were treated with 9% stannous-fluoride. Five minutes after treatment they and the unfluoridated left incisive teeth 31, 32 were extracted. For transformation of 19F to radioactive 20F the extracted teeth were exposed to neutrons in the nuclear reactor. The incorporated radioactivity was proportional to the fluoride-concentration. Considering fluoridated (128,45 +/- 13,659 mug/g) and unfluoridated (128,6 +/- 14,88 mug/g) teeth, the fluoride concentration did not differ significantly.
