Purpose: The surface degree of conversion and crosslink density of composites should not be affected by the use of instrument lubricants in order to provide long-lasting tooth restorations. This study aimed to analyze the effect of instrument lubricants on the degree of conversion and crosslink density of nanocomposites.
Materials And Methods: Samples (N = 10) were fabricated according to the composites (Filtek Z350 XT, 3M ESPE, St.
