It was aimed to comparatively evaluate the microleakage levels of different restorative materials applied after saliva contamination in posterior primary teeth with prepared different methods. In this in vitro study, three different restorative materials (compomer, high viscosity glass ionomer(HVGI), zirconomer) were applied to standardly prepared class II cavities in both mesial-distal regions of the teeth, using two different preparation methods (laser and aerator/bur). Following cavity preparation, half of each subgroup was contaminated with artificial saliva, and restorative materials were applied. After the laboratory procedures, microleakage for occlusal and gingival regions were evaluated. The data was analyzed statistically in the SPSS-20.0 program. The analyzes were completed with 66 teeth; the lowest mean microleakage score was observed in the laser-prepared-compomer-restoration group(LC) without saliva contamination in the occlusal region; and LC-group with saliva contamination in the gingival region. It was seen that compomer restoration showed less microleakage in the gingival region than zirconomer and HVGI restorations in the case without saliva contamination (p
