Summary

This study evaluates the accuracy of tooth color identification skills in the anterior region using a new technique, the button technique, in comparison with other methods.

Detailed description

The human eye is effective in detecting subtle differences in tooth color. However, variations in the shade, translucency, opacity, and characterization of a tooth may not be accurately identified. Visual color matching is subject to physiological variables that may lead to inconsistencies, such as age, gender, experience, the type of scale used, varying degrees of light exposure, eye fatigue, and color vision deficiency. Studies comparing visual and instrumental methods have demonstrated that spectrophotometers yield better results compared to visual color scales. Therefore, it is expected that color measurement devices improve the accuracy of tooth color determination, thereby enhancing the interpretation and aesthetic execution of restorations. In recent years, the button technique has been described for shade selection in direct aesthetic restorations in the anterior region. In this technique, small composite samples in the form of dots are polymerized on the tooth surface using a curing light. Digital photographs are then taken, and appropriate enamel and dentin shades are selected on a computer using polarized and black-and-white images. Very few clinical studies have investigated the use of digital color images obtained through intraoral digital scanners for shade selection, comparing them with other existing methods. The aim of this study is to evaluate the accuracy of shade determination skills in the anterior region by comparing a new technique, the button technique, with other methods and to recommend the most suitable method for shade selection

Conditions

• Tooth Discoloration

Interventions

Type	Name	Description
OTHER	Resins, Composite	Graduate students; healthy maxillary central teeth and color measurements will be performed with 4 different methods in at least 32 patients aged between 18-40 years. Firstly, students will be asked to make color measurements using the traditional method with two different color scales (Vita classical and Vita 3D master). As the third method; the enamel color of the teeth will be determined on digital photographs using the buton technique. Finally, tooth color will be measured on the buccal surface of the central teeth using a spectrophotometer.
