In Vivo Evaluations of Inter-Observer Reliability Using VITA Easyshade® Advance 4.0 Dental Shade-Matching Device.

Objectives: The aim of this study was to evaluate the inter-observer reliability of dental shade-matching device using an in vivo model.

Materials And Methods: Four observers who were well trained in color assessment and handling of the dental shade-matching device determined teeth color and CIE-Lab values on maxillary right central incisors in 10 patients with completely healthy and intact dentitions. VITA Easyshade® Advance 4.

In Vivo and in Vitro Evaluations of Repeatability and Accuracy of VITA Easyshade® Advance 4.0 Dental Shade-Matching Device.

Objectives: The objective of this study was to evaluate the intra-device repeatability and accuracy of dental shade-matching device (VITA Easyshade® Advance 4.0) using both in vitro and in vivo models.

Materials And Methods: For the repeatability assessment, the in vivo model utilized shade-matching device to measure the central region of the labial surface of right maxillary central incisors of 10 people twice.
