Comparison of Wear Resistance Between Innovative Composites and Nano- and Microfilled Composite Resins |
|
| چکیده فارسی مقاله |
Conclusions Estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. Estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. Results The wear amounts of the composites are as follows in order: Estelite sigma quick (1886.9 ± 518.5 μm2), Estelite flow quick (2708.9 ± 578.1 μm2), Estelite high flow (3206 ± 2445.1 μm2), Filtek Z350 (3840 ± 1963.4 μm2), and Filtek Z250 (4667.2 ± 2351.1 μm2). No statistical difference was found among the groups (P value > 0.05). Objectives Compare the wear resistance of new Estelite composites with that of other composites generations. Materials and Methods Thirty-five specimens were evaluated in five groups: three kinds of Estelite composites (Estelite Sigma Quick, Estelite Flow Quick, and Estelite Flow Quick High Flow), Filtek Z350, and Filtek Z250. All specimens were prepared in 25 mm disks and cured with laboratory light for 120 seconds (60 s for each side). Then, they were polished by 600 grit sand paper and stored for one week in distilled water at room temperature. We used a two-body abrasion test and the pin-on-disk method with distilled water as medium. All specimens were worn under 15 N load, 0.05 m/seconds speed, 100 m distance, and steatite ceramic balls antagonists. After wearing, we measured wear volume by calculating the wear track cross-section area with a profilometer and analyzed the data with the one-way analysis of variance (ANOVA) test. Background One of the most common causes of failure in class 2 posterior composite restorations is occlusal and proximal wear. Estelite composites used supra-nano monodispersing spherical fillers and a new photoinitiator, and the manufacturer claimed that the wear of these composites is less than 1 mm3 volumetric wear. |
