    The Effect of Combined Application of Tricalcium Phosphate Containing Varnish and ER, CR: YSGG Laser on Resistance of Enamel to Caries: An In Vitro Study
    Author(s): Hussein Sami Abdullah* and Aisha Akram Qasim

    Background: This study aims to investigate the efficacy of functionalized tri-calcium phosphate containing varnish combined with ER, CR: YSGG laser in preventing of enamel caries. Materials and Methods: Freshly extracted 50 sound upper first premolars teeth were divided into five groups, each group of ten samples. Group (C): only washed with deionized water. Group (V): functionalized tricalcium phosphate (fTCP) exclusively from Clinpro White Varnish. Group (L2): Er,Cr:YSGG laser (0.75 W, 8.5 J/cm2, 20 Hz, 11% air, 0% water) was irradiated. Group (V/L2): First Clinpro White varnish was applied then Er,Cr:YSGG laser. Group (L2/V): Er,Cr:YSGG laser was irradiated followed by Clinpro White varnish. Then, the pH cycling model was used to induce artificial caries. The effect was studied in vitro using Vickers microhardness test and the obtained results were.. Read More»
