Influence of Ukrain and strontium on the rat tooth intertubular dentine. II. Atomic force microscopy study

The effects of different doses of Ukrain and/or strontium on the rat tooth intertubular dentine were analysed in cuts perpendicular to the dentinal tubes. The tooth surface and tooth cross-sections morphology and roughness were investigated with atomic force microscopy. The surface morphology and roughness of the dentine from seven groups of animals was examined with tapping-mode atomic force microscopy. The cross section surface of intertubular dentine was analysed by roughness and fractal parameters. Histograms were prepared for the typical samples from all the analysed groups of teeth. Dentine cross section surfaces showed significant and distinguishable differences between nano structures of the normal control rat teeth and those from animals administered with Ukrain and strontium.
