A visual analysis by dentists and patients of single-shade resin composite in non-carious cervical lesions: A prospective study.

Purpose: To visually analyze the chromatic behavior of single-shade resin composite in non-carious cervical lesions (NCCLs) and assess its acceptability among undergraduate and graduate students, dentistry professors, and patients.

Methods: Restorations were performed on NCCLs using the single-shade resin composites Omnichroma (OC) and Vittra APS Unique (VT), with Filtek Z350 XT (FT) as the control. Patients with three or more NCCLs in consecutive teeth were included, and 22 restorations were visually analyzed by 20 evaluators who were tested for color vision deficiency. The restorations were evaluated based on World Dental Federation (FDI) criteria after 6 months, and a survey was completed by patients after 6 months. Data were analyzed using the Kruskal-Wallis test.

Results: OC performed significantly better than VT (P= 0.020), but with no significant difference compared to FT (P= 0.441). OC had a 96.43% success rate in terms of color and translucency, compared to FT (92.50%) and VT (77.22%). Single-shade resin composites showed satisfactory compatibility in terms of color, translucency, and shine for NCCLs, as evaluated by both professionals and patients.

Clinical significance: Single-shade resin can be used with promising results for NCCLs, with Omnichroma being recommended as it had the best performance.
