Description
Summary:<b>Background</b>: In prosthodontics, achieving esthetic success requires precise shade matching of restorations to natural teeth. This study evaluated the shade-matching abilities of fourth-year dental students using different tools and conditions in laboratory (LB) and clinical (CL) settings. <b>Methods</b>: In the LB setting, students matched blinded shade tabs to the VITA classical shade guide under natural daylight (ND), artificial light (AL), and a polarized filter (PF). In the CL setting, they determined the shades of patients’ central incisors using the same conditions. Participants also completed a questionnaire about their experience. <b>Results</b>: Quantitative analysis showed better shade matching in the LB setting, particularly with the PF (52% correct), compared to ND (50%) and AL (43%). In the CL setting, overall accuracy dropped to 32% across all conditions. No results were statistically significant. Qualitative feedback revealed that students found the spectrophotometer to have improved their accuracy and reliability compared to the ND and AL conditions. <b>Conclusions</b>: This study highlights the importance of incorporating technology as a validation tool in dental practice. Leveraging tools like spectrophotometers may enhance shade-matching accuracy, streamline processes, and improve patient satisfaction while balancing traditional methods with technological advancements.
