Clinical Evaluation of Color Stability of Direct Composite Resin Veneers in Vital Anterior Teeth

In today's restorative dentistry, aesthetics has become essential. The primary determinants of the aesthetics of natural teeth are color and form. The significance of color in dental science has greatly increased during the past few decades.

Techniques to restore teeth to their natural appearance have been developed in direct response to patient demand for cosmetic dental procedures. In contemporary cosmetic dentistry, discolorations are often seen as an aesthetic concern.

In order to correct cosmetic flaws in color and form, direct laminate veneers entail the creative application of resin composite material to the tooth surfaces. Because they may be completed chairside, are readily repaired, and have abrasion rates that are similar to those of real teeth, they are viewed as competitors to ceramic veneers.

With direct resin composite veneers, color stability is thought to be a common clinical issue that reduces the aesthetic result over an extended period of clinical service. The capacity of any dental material to retain its original color is known as color stability.

The clinical restoration process is streamlined with the introduction of universal composites, which also considerably reduce chair-side time and simplify the color matching such as OMNICHROMA.
