Artigo IPEN-doc 21289 FTIR spectroscopy revealing the effects of laser and ionizing radiation on biological hard tissues2015 - ZEZELL, DENISE M.; BENETTI, CAROLINA; VELOSO, MARCELO N.; CASTRO, PEDRO A.A.; ANA, PATRICIA A.Artigo IPEN-doc 14980 Changes in dental enamel oven heated or irradiated with Er, Cr:YSGG laser2010 - RABELO, J.S.; ANA, P.A.; BENETTI, C.; VALERIO, M.E.G.; ZEZELL, DENISE M.This study evaluated the change that occurs in dental enamel under action of oven heating or Er,Cr:YSGG laser irradiation aiming to obtain a structure more resistant to demineralization. Enamel pow der was obtained from bovine teeth. Samples were subjected to oven heating at temperatures of 200, 400, 600, 800, and 1000°C or during laser irradiation with energy densities of 7.53, 10.95, and 13.74 J/cm2 . The infra red thermography was used to measure the surface temperature generated in the solid samples of enamel dur ing lasers irradiation. The samples were analyzed by Fourier transform infrared spectroscopy (FTIR), which shows changes on enamel oven heated or laser irradiated, due to treatments, related to carbonates, adsorbed water and hydroxyl content. These compositional effects were more evident in lased samples. These changes may alter the material properties such as its solubility, and decrese of demineralization that is important for caries prevention.Artigo IPEN-doc 19177 Influence of Er,Cr:YSGG laser on CaFsub(2)-like products formation because of professional acidulated fluorides or to dentifrice application2013 - ZAMATARO, CLAUDIA B.; ANA, PATRICIA A.; BENETTI, CAROLINA; ZEZELL, DENISE M.
