Abstract


Aim:  To compare and access the reliability of visual shade matching and spectrophotometer shade matching systems.  Material and methods: A total of 10 dental students from final year, who volunteered to participate in the study. For shade matching labial surface of maxillary central incisor (middle third) was assessed for 5 test subjects. The visual shade selection method was done using the commercially available shade guide VITAPAN 3D Master and for the instrumental shade selection method, the spectrophotometric shade matching was done using an intraoral spectrophotometer VITA Easyshade. Differences in colour (ΔE) and value (ΔL) between the natural teeth and the shade determined for each method. Statistical evaluation was done using statistical software SPSS version 21 (IBM Inc., Armonk, NY, USA and Chi square test. Results: Overall, the spectrophotometric method was found to be more accurate in colour selection than the conventional visual method. The light difference (ΔL) for both the methods was not statistically significant.  Conclusion: Thus, as per the variables of our study that the spectrophotometric method of shade selection definitely proves to be a better option than the conventional visual shade guide method.
