The reliability of digital cameras for color selection

Int J Prosthodont. 2005 Sep-Oct;18(5):438-40.

Abstract

Purpose: This study evaluated the validity of the color selection results obtained from digital cameras.

Materials and methods: Four observers matched the colors of 30 extracted maxillary incisors under daylight conditions. Two different digital cameras, with 1.5- and 5.0-megapixel resolutions, were used to select the color of the standardized circular area with 3 reference points on the same teeth; a spectrophotometer was also used, and the results were compared with the human and camera observations.

Results: The highest significant agreement (60% agreement with the spectrophotometric values) was found with the 5.0-megapixel camera.

Conclusion: It appears that the resolution capacity of a digital camera can increase the reliability of color selection.
