AIM: To evaluate visual perception of dental color carried out by students and professors of Dentistry area. MATERIAL AND METHODS: For this study, 64 people were selected to respond a personal questionnaire and a color selection questionnaire. The respondents also perform, using the color scale VITAPAN classical, the choice of healthy human tooth color, maintained humid and in an acrylic resin cylinder developed especially for this research. RESULTS: Only 6.25% of respondents answered correctly the natural tooth color. CONCLUSION: According to the color verification through a spectrophotometer, only 6.25% of respondents have carried out correctly the color selection. In this way, for the good aesthetical result, the criteria need to be standardized and pre-stablished in order to perform the color selection correctly, observing the variables which can interfere on its choice.

HMT cylinders showed significant differences in marginal misfit (2.48 ± 1.07 μm) compared to LMT (1.53 ± 0.37 μm) and control (1.27 ± 0.57 μm) cylinders, but there were no differences in dimensional stability. HMT Co-Cr alloys produce implant-supported prostheses with poor marginal fit.
