Abstract
Aim: The physicochemical properties of dental graft materials are very important because they strongly influence the bone regeneration capabilities of biomaterials. The purpose of this study is to investigate the chemical composition and surface energies of white (WPTG) and black porous titanium granules (PTG), bovine bone graft and equine-derived bone graft through energy dispersive X-ray spectrometry (EDX) analysis of the comparison.
 Methodology: The surface chemical compositions of PTG, WPTG, bovine bone graft and equine-derived bone graft were measured by EDX analysis. All graft materials’ morphologic characteristics such as particle and granule dimension were evaluated with Scanning Electron Microscopy (SEM). The EDX measurement of samples was evaluated at between x85 to x50000 magnification.
 Results: PTG grafts showed elements of sodium (%8.88±9.98), chlor (2.44±1.96) and aluminum (0.99±0.37) as well as titanium (90.06±11.34) molecule at x5000 magnification. In WPTG, titanium (%34.55±6.41) and oxygen (%65.44±6.42) molecules were detected. EDX analyses have detected the presence of sodium, calcium, and phosphorus in the equine-derived and bovine bone graft.
 Conclusion: It has been found that PTG surface was not made of pure titanium, it has different chemical molecules at larger magnifications and xenografts exhibited different organic material content. Cell culture and experimental studies are needed to establish a relationship between the different commercial dental grafts and their regenerative properties.
