Color Stability of Bulk-Fill Flowable Composite Vs Conventional Flowable Composite after Accelerated Aging. Comparative In-Vitro Study.

摘要

ABSTRACT This study was carried out to compare the color stability of two different types of resin composite after accelerated aging. Specimens of X-tra base (VOCO GmbH) bulk fill flowable composite and Grandio flow (VOCO GmbH) flowable composite were aged in a weather chamber device for 296 hours with a total energy of 300 kilojoules . Color assessments were done before and after aging. The color change was calculated from the following equation: E= [(L) .
