title: [Concerning the reversibility of initial carious lesions in the fissure region (author's transl)].
abstract: Using a light microscope, the authors compared longitudinal ground sections of human premolars from a region where the drinking water contains 1,0 p.p.m. of fluorine with the preparations from a region where the drinking water contains 0.35 p.p.m. of fluorine. Under the microscope, "healty" teeth may also show initial carious lesions in the fissure region. These changes are significantly less frequent in premolars which developed under the influence of fluorine. This finding and an age-depending decrease of the initial carious lesions in the fissures militate in favour of the reversibility of these changes.
