Abstract :Purpose Cavity disinfection, in addition to routine caries removal methods, is recommended to eliminate the microorganisms. The aim of this study was to compare the effect of various systems Er,Cr:YSGG lasers, diode lasers and FotoSan and agents Corsodyl; Cervitec and Cervitec Plus and Fluor Protector—on the nanoleakage of compomer restorations when used for cavity disinfection. Materials and Methods A total of 40 intact human deciduous molar teeth containing Black V cavities insert ignore into journalissuearticles values(3×2×1.5 mm); on the buccal and lingual surfaces parallel to the cementoenamel junction were randomly divided into 8 groups according to the cavity disinfection methods. The antibacterial agents and systems were applied according to the manufacturer’s instructions. Restorations were completed using a compomer. The restored teeth were then subjected to thermocycling for 500 cycles in a water bath at 5°C and 55°C with a dwell time of 30 seconds. After the thermocycling procedures, 1-mm sticks were obtained from the center of each cavity to prepare for the nanoleakage test. After the teeth were sectioned, they were immersed in 50 wt % ammoniacal silver nitrate solution for 24 hours and dipped in photo-developing solutions for 8 hours with fluorescent light irradiation. The samples were examined under a scanning electron microscope insert ignore into journalissuearticles values(SEM);. The non-parametric Kruskal-Wallis and Mann-Whitney U test insert ignore into journalissuearticles values(p<0.05); were applied. Results The Er,Cr:YSGG laser group showed significantly less nanoleakage than all of the tested groups insert ignore into journalissuearticles values(p<0.01);. The diode laser, Fluor protector and FotoSan groups showed similar nanoleakage to that of the control group insert ignore into journalissuearticles values(p>0.05);. The Corsodyl insert ignore into journalissuearticles values(p<0.01); and Cervitec insert ignore into journalissuearticles values(p<0.001); groups showed significantly higher nanoleakage than the control group. Conclusion Er,Cr:YSGG laser irradiation which showed lower nanoleakage scores from either control or tested groups can be recommended for cavity disinfection Additionally, a diode laser and FotoSan, which have antibacterial effects and no negative effect on leakage, can be used for cavity disinfection.
