Comparative Evaluation of Shade Matching of Vital Maxillary Central Incisor by Different Observers, Shade Guides and Instrument.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 3
Abstract
Objectives: This study tested the hypothesis that the agreement between observer visual dental shade matches and instrumental shade identification is higher using the Vita 3DMaster ® (3D) shade guide than the Vita classical (VC) shade guide. Methods: 100 subjects were matched with visual and instrument; spectrocolorimeter for shade selection and result were tabulated. Results: The result obtained showed that Spectrocolorimeter has more value of lightness, redness or greenness, blueness or yellowness (L*,a*,b*) when compared with Vitapan classical and Vitapan 3D Master. Vitapan 3D Master has more lightness, redness or greenness (L*, a) is more than Vitan Classical expect blueness or yellowness of colour. Significance: A significantly higher visual–instrumental shade agreement was demonstrated by the clinically experienced dentists (DD), regardless of shade guides and lighting conditions. Incandescent light bulb emits relatively higher concentrations of yellow light waves than of blue and blue-green, whereas fluorescent ceiling fix-lures give off relatively high concentrations of blue Waves.
