“…G-aenial is a hybrid composite restorative with a combination of two types of pre-polymerized resin fillers (silica and strontium and lanthanoid) having the mean size of 16-17 µm, silica as inorganic filler with more than 100 nm size and fumed silica as inorganic filler with less than 100 nm size. Degradation of composite resins is in a direct relation with the storage solution [13]. It was showed that the pH of immersion solution can accelerate the erosive wear.…”

Abstract. The aim of the study was to evaluate the surface roughness of two commercial composite resins submitted to erosive attack, to abrasive wear and to association of erosive and abrasive challenge. Standardized samples of G-aenial anterior (GC Company) and Essentia (GC Company) composite resins were randomly split in 6 groups. In group 1 the samples were maintained in artificial saliva until the evaluation of surface roughness. In group 2 the samples were submitted only to erosive attack, in group 3 only to abrasive challenge and in groups 4 ,5, and 6 the erosive attack was followed by abrasive challenge immediately (group 4), 30 minutes after the erosive attack (group 5) and one hour after the erosive attack (group 6). The specimens were evaluated using surface roughness measuring tester SJ-210 (Mitutoyo Corporation, Japan) and the mean surface roughness values (Ra, µm) of each specimen were registered. A significantly increase of both composite resins surface roughness was recorded after erosive attack and abrasive challenge. Toothbrushing 60 minutes after acidic contact determined no significant differences in surface roughness of composite resins.

Surface characteristics of two composite resins (Filtek Ultimate Universal Restorative, 3M ESPE and Filtek Ultimate Flowable Restorative, 3M ESPE) after finishing and polishing procedure using three systems: two steps Sof-Lex system, 3M ESPE, multi-steps Super Snap system, Shofu, Inc. Kyoto, Japan and multi-steps OptiDisc system, KerrHawe SA were analyse using SEM and AFM investigations. Fractal analysis was performed on SEM and AFM images and the mean fractal dimension was calculated for each sample using FracLac software. For both tested materials decreased fractal dimension with the increase of SEM magnification was observed. Multi-steps OptiDisc system determined the biggest decrease of fractal dimension for both materials, followed by Sof-Lex system and Super Snap. Fractal analysis seems to be an appropriate method to investigate the complex structure of composite resins.
