Summary
Introduction: Proper finishing of resin composite surfaces enhance the longevity and esthetics of tooth restorations.
Aim: The aim of the study was to evaluate the influence of selected polishing systems on surface roughness of resin-based nanofill composite Filtek Supreme and resin-based nanohybrid composite Synergy D6.
Material and methods: Twenty samples of each composite were prepared and randomized to 4 treatment groups, according to polishing procedure: A (control) – Sof-Lex system + polish rubber (3M ESPE), B – soflex system + polish rubber + Poligloss paste (3M ESPE, TDV), C – Sof-Lex system + polish rubber + Impregnated Felt Discs (3M ESPE, TDV), D – Sof-Lex systems + polish rubber + Diamond Gloss Paste (3M ESPE, TDV). The average surface roughness (Ra value) for each group was measured and calculated by prophylometry. Additionally, composite surfaces were examined with SEM. One way ANNOVA was used for statistical analysis (p < 0.05).
Results: The Ra values were significantly (p < 0.05) lower, Ra = 0.33 (± 0.1) and 0.85 (± 0.39) in D groups for Filtec Supreme and Synergy D6, respectively. The roughness registered in A, B, C, D groups for Filtec Supreme was significantly lower than for Synergy D6.
Conclusions: The polishing system based on diamond paste is the most effective for nanofill and nanohybrid composite surface finishing. The higher level of polishability was observed for nanofill composite as compared to nanohybrid one.
