Evaluation of 2-year Clinical Performance of Two Different Single Color Universal Composite Resin Restorative Materials.

Dentists have recently preferred to use composite materials and restorative techniques that allow the use of simplified clinical protocols in order to reduce the time the patient spends in the dentist's chair and minimize technical sensitivity. Color selection in the clinic is a very sensitive process and is affected by environmental factors and operator-related variables. This has led to the development of single-color universal composite resins that aim to facilitate color selection. These materials have a universal opacity and several Vita shades and are recommended by manufacturers to be used in a single color layer that can match different tooth colors. In recent years, monochromatic universal composites have been developed that are supposed to be compatible with all Vita Classic Scale shades from A1 to D4. Manufacturers report that single-color universal composites can be applied to teeth of all colors without using the layering technique using different color composites. Therefore, the aim of this study is to compare the clinical performance of 2 different single-color universal composite resin materials (OMNICHROMA and Zenchroma) in the restoration of non-carious cervical lesions with the control group (Filtek Z250, 3M), which is a multi-color composite resin material, using modified US Public Health Service (USPHS) and World Dental Federation (FDI) criteria.
