Aim: The aim of the study was to evaluate and compare two techniques of shade matching using VITA shade guide under color-corrected light and mobile application DentHue with VITA shade guide under natural light. Materials and Methods: 100 subjects were selected for the study. The visual assessment was based on a comparison between a shade guide and the target tooth. The shade of the tooth was assessed using VITA classical shade guide in natural daylight, using VITA shade guide with a color-corrected light (true light) and a mobile application DentHue. The shade matching using color-corrected light and with the application was compared with that done by VITA shade guide. Results: It was found that there were 69 (69%) correct identifications of the shade when matched under color-corrected light while 31 (31%) were incorrectly identified. It was also found that there were 38 (38%) correct identifications performed by DentHue while there were 62 (62%) incorrect identifications of the shade. This difference was statistically significant (P < 0.05). Conclusion: The use of color-corrected light demonstrated superior accuracy in shade matching using the VITA shade guide as compared to DentHue.
