title: [Study of the initial enamel injuries in vitro].
abstract: The purpose of the study was production under laboratory conditions of enamel changes corresponding to early caries. The study was carried out on 20 healthy human teeth in vitro, in two phases differing in the conditions of the experiment. Carietic changes were produced with lactate buffer (in concentrations from 0.025 to 1.0 M) as fluid without added inhibitor of the solubility of the superficial layer. The assessment of the degree of enamel demineralization was based on images obtained in JSM 50A scanning microscope. In the first stage of the experiment a minimal demineralization of the subsuperficial layer of the enamel was obtained. In the second stage besides damage to the subsuperficial layer enamel erosion was noted. In this connection further studies are necessary for determining of the proper conditions for obtaining initial enamel damage.
