Color Adjusting Resin Composite in Anterior Tooth Restorations: Clinical and Subjective Evaluations
Clinical and Subjective Evaluations of a Universal-Shade, Color Adjusting Resin Composite in Anterior Tooth Restorations: A Randomized Controlled Trial
King Abdullah University Hospital
120 participants
Mar 10, 2025
INTERVENTIONAL
Conditions
Summary
The ability of single-shade composite restorations to blend with adjacent tooth structure shades is called chameleon effect. This effect is enhanced using specially designed spherical particles in the composite material which will help diffuse light in a way that mimics the natural color and translucency of teeth making the restoration nearly imperceptible to the naked eye. The hypotheses of the investigation are as follow: * Single-shade RBC exhibits similar shade matching and optical behavior to conventional RBC across all anterior restorations. * Patient satisfaction regarding color blending between the restoration and tooth structure is comparable regardless of the type of material used. * Dentist satisfaction regarding color blending is similar for both single-shade RBC and conventional RBC materials.
