Water sorption properties can alter the color stability of composite resin purpose. </em><span style="font-family: Tribune-Bold; font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><strong>Purpose: </strong><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>This study was to determine the influence of immersion durations of composite resin in soft drink on color stability. </em><span style="font-family: Tribune-Bold; font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><strong>Methods: </strong><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>The visible-light cured hybrid composite resin and soft drink were used.

The initial color of </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>specimens were measured by Chromameter.
