In vitro Study Using ATR-FTIR Methode for Analyze the Effects of the Carbamide Peroxide on the Dental Structure

Abstract:

This study aims to analyze the effect produced by carbamide peroxide solution used in the teeth whitening process on the enamel and dentin structure through the Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) technique. To carry out the in vitro study, we used three different types of teeth, namely the incisor, premolar and molar, as well as three different concentrations of peroxide carbamide, namely 10%, 16% and 35%, for 90 min. We measured and compared the frequency bands as phosphate (PO4-3) and carbonate (CO32-) by FTIR spectroscopy method both before and after whitening. The study showed that FTIR method is useful for the analysis of the organic and inorganic structure of enamel and dentin, the highest modifications being noticed when using the 35% peroxide carbamide concentration by the reduction of the mineral component especially carbonate and phosphate anions. Keywords: ATR-FTIR, carbamide peroxide, dental structure
