Clinical Evaluation of Flowable Monochromatic and Polychromatic Composite Resins in Posterior Restorations

Plain-language summary

This clinical study aims to investigate whether a single flowable composite resin system can achieve adequate color matching in posterior restorations and to compare it with a polychromatic composite system, which will serve as a control group. Clinical success will also be assessed using data obtained from the initial, six month, one-year, two-year, three-year, four-year, and five-year recall checks of the four different composite resin systems used in the study over a five-year period. L, a, and b parameters will be determined using the Vita Easyshade Compact (VITA Zahnfabrik, Bad Sackingen, Germany) Spectrophotometer device used in the study at the initial, half-year, one-year, two-year, three-year, four-year, and five-year intervals. Based on the obtained data, intraoral color changes will be determined using the CIEDE2000 color system. Each patient will be scanned with an intraoral scanner at each session. The hypothesis tested was that color matching and long-term clinical follow-up would be successful for all composite materials used in the study.
