Abstract

The masking efficiency of resin composite affects the aesthetics of dental restorations. There are several methods for measuring color masking. Using the human eye has the advantage of being easy to perform, but the drawback is that it is unreliable. Using a spectrophotometer has the advantage of being more accurate, but it can be more challenging to use. In clinical practice, color selection for dental restorations is often done using the human eye. This research compared the masking efficiency measurement of the human eye and a spectrophotometer. Two resin composites, Clearfil AP-X shade A2 and Metafil CX shade A1, with 0.5-, 1-, 1.5-, and 2-mm thickness levels, were restored to measure color masking using the human eye and a spectrophotometer. The results were analyzed using Sum masking values obtained from the human eye and ∆E values obtained from the spectrophotometer. It was found that both values were correlated. In summary, the masking efficiency measurement of the human eye corresponds to the spectrophotometer. The Metafil CX resin composite has higher masking efficiency than the Clearfil AP-X in achieving an aesthetically acceptable shade.
