Abstract

Introduction: One of the main objectives of composite restorations procedure is to obtain a smooth surface for aesthetic reasons and for oral health.

The aim of this study was to assess the surface morphology of a bulk fill composite material after finishing and polishing with three different finishing and polishing systems.

Materials and methods: Filtek Bulk Fill Posterior composite resin was chosen for this study (3M ESPE St. Paul, MN, USA). Twenty cylindrical samples 5 mm in diameter and 2 mm thick were made using plastic molds. They were randomly and equally assigned to four groups. In group 1 (control) the samples were not subjected to finishing and polishing procedure.

The surface characteristics of the samples were quantitatively analyzed using profilometry and qualitatively evaluated by scanning electron microscopy. The Kolmogorov-Smirnov normality test was used to determine the distribution of data in groups. ANOVA and Tukey post hoc statistical tests were used to compare the results in groups.

Results: Finishing with tungsten carbide burs and two-steps Sof-Lex polishing system and one-step polishing system Occlubrush determined, higher roughness when comparing to multi-step Super Snap system.

Conclusion: The surface characteristics of the studied composite resin were influenced by the type of finishing and polishing system used.

Keywords: bulk-fill composite, finishing and polishing systems, profilometry, SEM.
