title: Temperature stability of carbonate groups in tooth enamel.
abstract: The tooth enamel EPR signal at g = 1.9973 consists of several components, which correspond to different functions of the spatial orientation of the CO2- radicals, have different temperature stability and different saturation curves. Using a new technique described in this paper, we have detected and investigated two groups of CO2- radicals with different thermal stability and saturation characteristics.
