    Role of Er.Cr: YSGG Laser and Fluoride in Caries Resistance
    Author(s): Ahmed Adnan Hadi* and Basima Mohammed Ali

    The purpose of this study was to compare the effectiveness of using the Er.Cr: YSGG laser with and without Acidulated Phosphate Fluoride (APF) to improve tooth resistance to caries. Sixty enamel sample obtained from first premolar teeth (4 mm × 4 mm) were randomly divided into six groups (n=10): G1: control group (no treatment), G2: Acidulated Phosphate Fluoride (APF) only, G3: Er, Cr: YSGG laser at 0.25 W, 20 Hz, 1% water and 10% air, G4: Er, Cr: YSGG laser at 0.50 W, 20 Hz, 1% water and 10% air, G5: Er, Cr: YSGG laser at 0.25 W, 20 Hz, 1% water and 10% air and acidulated phosphate fluoride, G6: Er, Cr: YSGG laser at 0.5 W, 20 Hz, 1% water and 10% air and acidulated phosphate fluoride. The samples were subjected to pH cycling for 10 days after being irradiated and treated. The samples were tested for digital vickers micro hardness on (9.8 N) at the enamel surface on baseline, a..
