Objectives: The purpose of this experiment was to evaluate four different polishing systems of their polishability
and polishing time.
Materials and Methods: 4 mm diameter and 2 mm thickness Teflon mold was made. Z-250 (3M ESPE)
hybrid composite resin was slightly overfilled and pressed with slide glass and cured with Optilux 501 for
40 sec each side. Then the surface roughness (glass pressed: control group) was measured with profilometer.
One surface of the specimen was roughened by #320 grit sand paper and polished with one of the following
polishing systems; Sof-Lex (3M ESPE), Jiffy (Ultradent), Enhance (Dentsply/Caulk), or Pogo
(Dentsply/Caulk). The surface roughness and the total polishing time were measured. The results were
analyzed with one-way ANOVA and Duncan’s multiple range test.
Results: The surface roughness was lowest in Pogo, and highest in Sof-Lex. Polishing times were shortest
with Pogo, and followed by the Sof-Lex, Enhance and Jiffy.
Conclusions: One-step polishing system (Pogo) is very effective to get the smooth surface in a short time,
therefore it can be recommended for final polishing system of the restoration.
