Abstract

OBJECTIVE:

The aim of this in vitro study was to evaluate the accuracy of shade matching using two spectrophotometric devices.

MATERIALS AND METHODS:

Thirteen patients who require a full coverage restoration for one of their maxillary central incisors were selected while the adjacent central incisor was intact. 3 same frameworks were constructed for each tooth using computer-aided design and computer-aided manufacturing technology. Shade matching was performed using Vita Easyshade spectrophotometer, Shadepilot spectrophotometer, and Vitapan classical shade guide for the first, second, and third crown subsequently. After application, firing, and glazing of the porcelain, the color was evaluated and scored by five inspectors.

RESULTS:

Both spectrophotometric systems showed significantly better results than visual method (P < 0.05) while there were no significant differences between Vita Easyshade and Shadepilot spectrophotometers (P < 0.05).

CONCLUSION:

Spectrophotometers are a good substitute for visual color selection methods.

KEYWORDS:
