Abstract

We have presented Analysis of UV irradiated dental nanocomposites restorative materials using laser-induced breakdown spectroscopy (LIBS). Samples of the materials are irradiated with UV light using 3M ESPE Elipar FreeLight2 Source. LIBS spectra of the samples are recorded using fundamental beam from Q-Switched Nd: YAG laser in conjunction with MS257 Spectrograph (Oriel instrument) equipped with Andor iStar ICCD camera. The emission spectra of these samples have been recorded as a function of laser irradiance. Traces of Titanium, Silicon, Aluminum, Strontium, Zirconium, Sodium and Calcium are detected in these samples. The elemental composition is found to be quite similar but the relative abundance of Zr and Si is higher in more UV exposed material. The samples have also been analyzed with SEM EDS for comparison.
