Innovative dental materials that have antimicrobial properties are highly desirable in the oral cavity. The aim of this study was to evaluate the antimicrobial activity of nanostructured silver vanadate (²-AgVO3) incorporated in dental ceramics against Streptococcus mutans and Streptococcus sobrinus, while examining the mechanical properties and the incorporation pattern of the nanomaterial into ceramics. The antimicrobial properties of the ceramic incorporated with different percentages of ²-AgVO3 will be investigated by the reduction of the XTT method, colony forming units (CFU) and epifluorescence microscopy and the mechanical behavior through microhardness tests, surface roughness, flexural strength and fracture. The incorporation pattern of ²-AgVO3 in the ceramic will be analyzed by scanning electron microscopy (SEM) and elemental analysis by dispersive energy (EDS). The data will be analyzed statistically depending on its distribution pattern.
