Abstract
This
study evaluated the influence of polishing protocols on the surface
roughness of flowable and regular bulk fill composites. Five bulk fill
composites were tested: SureFil SDR Flow (SDR), Tetric EvoFlow Bulk fill
(TEF), Filtek Bulk Fill Flowable (FIF), Tetric EvoCeram Bulk Fill
(TEC), and Filtek Bulk Fill Posterior (FIP). Two polishing protocols
were tested: Sof-Lex and Astropol. Astropol created a smoother surface
for FIP (P < .05); however, the polishing protocol did not influence
surface roughness on TEC (P > .05). SDR, TEF, and FIF exhibited
rougher surfaces when polished. Sof-Lex created rougher surfaces for
bulk fill composites. It was concluded that surface roughness was
related to material composition rather than the polishing system.
