Non invasive investigation in class II fillings, such as optical coherence tomography (OCT), is slowly entering in the usual dental arsenal of the direct restoration analysis. Working at more than 2 mm depth inside the samples could lead to problems related to the evaluation of the adhesive layer. At this level is difficult to point out the area with adhesive or adhesive with aeric inclusions. For this reason a new metallic Nano particles modified dental adhesive is used in order to increase the scattering of the normal adhesive and gain a good contrast on the OCT investigation. The validation of the results were done with SEM and EDAX procedures. In conclusion, noninvasive evaluations methods like OCT, especially OCT working in Time Domain mode, have a great capability to evaluate the interfaces between dental structure, resin fillings and dental adhesive when a metallic Nanoparticles modified adhesive is used.
