520			_aObjective: the aim of this in vitro study was to evaluate the penetration efficacy of a caries infiltrant resin with different etching and application times. Materials and Methods: In this study ninety non carious human incisors free from cracks or any structural defects were immersed in a demineralizing solution in order to create artificial subsurface carious lesions. Specimens were divided into three equal groups according to etching time then they were furtherly divided into three subgroups according to application time. After application of the infiltrant resin, specimens were embedded in transparent scaffolds and sectioned. Specimens were immersed in a 100æMj/sodium fluorescein for 3 hours. Digital images were obtained using light stereo microscope at 120x. Results were analyzed using ANOVA test. Results: Revealed a significant difference between different application times (P<0.0001). Using 30sec. etching time, the highest significant mean value was recorded in B1 (4min application time), whereas the lowest significant mean value was recorded in B3 (2min application time). Using 60sec. etching time, ANOVA test revealed no significant difference between different application times (P=0.08), the highest mean value was recorded in B1 (4min application time), whereas the lowest mean value was recorded in B3 (2min application time). Using 120sec etching time, ANOVA test revealed a significant difference between different application time (P=0.049)
