Color Match Clinical Evaluation and Patients’ Acceptability for a Single Shade Universal Resin Composite in Class Iii and V Anterior Restorations

Abstract

This study evaluated the capability of a single shade universal resin composite [Omnichroma® (OMRC)] to match the tooth color. Forty-five conservative cavities (Class V and III) were prepared in a total of 21 patients. The adhesive system and OMRC were applied according to the manufacturer instructions. After 60min. of restoration placement, the color the of restoration and the tooth were recorded using a digital spectrophotometer. Color-matching visual scoring (VS) was also done by two PhD-students. Patients' acceptability of the restoration was done using Likert 5-point scale. Data were statistically analyzed using paired t-test, significance level was set at P ≤ 0.05. Results revealed that there was a statistically significant change in the brightness (ΔL) (p < 0.001), while no significant difference in the a* and b* parameters between the restorations and the teeth were shown. Color changes of the restorations compared to the teeth (ΔE) ranged from 2.01-8.54 (5.14±1.38). VS showed more than 70% of the cases clinically unacceptable by both observers. More than 80% of the patients showed neutral to satisfied acceptability for the restorations. It was concluded that OMRC showed poor clinical color matching values in anterior teeth and were unacceptable to the PhD dental students. There was a high acceptability level among the patients for OMRC
