M., DOĞU KAYA B., MANAV ÖZEN A., Öztürk S., ALKAN E., YILMAZ ATALI P., KORKUT B., TAĞTEKİN D.Introduction: The purpose was to investigate the surface roughness and the color changes of nanohybrid and microhybrid resin composites subjected to calcium active whitening toothpastes with different RDA values through a novel Press-on Force-Guided (PFG) Brushing Simulator. Material and Methods: Twenty-eight disc-shape samples (10x2mm) of a nanohybrid (Herculite, Kerr) and a microhybrid (Z250, 3M) composites were prepared and randomly divided into 4 subgroups (n=7). The samples were polymerized with a LED-curing unit with an irradiance of 1000 mW/cm2 (Valo Cordless, Ultradent). Finishing and polishing procedures were performed with 2 fine grits of Sof-Lex Discs (3M). Samples were stored in distilled water at 37°C for 24 hours. Composite samples were brushed with a medium-bristle toothbrush (ROCS Pro 5940, ROCS) using the PFG brushing simulator (Marmara University, Turkey) for 60.000 strokes (correspondence to 6 years clinically) in a slurry containing toothpaste with 120 RDA (Ca Active Whitening, ROCS) and 70 RDA (Electro Whitening, ROCS) under 300-320g load (200 strokes/min). In particular, surface roughness (Ra) and color change (ΔE) were investigated utilizing profilometer (MarSurf PS 10, Mahr) and spectrophotometer (Easy-Shade-5, VITA). Analysis of variance was used for repeated measurements; Bonferroni test was used for pairwise comparisons. The level of significance was set at p<0.05. Results: After brushing Ra values did not show a significant difference (p>0.05) except Herculite group brushed with Electro whitening (p=0.05) which showed the most roughness change (36.99%). There is a significant difference between Herculite (1.163±0.701) and Z250 (0.400±0.154) in Ra values after electro-whitening brushing (p=0.002). No significant color change was observed in any group, regardless of composite or tooth-paste type (p>0.05). ΔE values of Herculite (1.007±0.463; 1.100±0.452) and Z250 (1.558±0.618; 1.196±0.835) brushed with Ca Active Whitening and Electro Whitening toothpastes were less than 1.8 respectively. Conclusion: Tooth brushing with Ca active whitening toothpastes (different RDA values) affected differently on the surface roughness of Herculite and Z250 due to their filler and resin composition, but there is no effect on color.

Materials and Methods: 80 enamel samples were kept in the demineralization solution (pH 4.5, 37°C) for 96 hours. Demineralized enamel samples will be randomly divided into 8 groups (n=10) including a remineralizing agent(Toothmousse/GC, Remin Pro/VOCO, Medical Mineral Gel/ROCS), resin infiltration (ICON/DMG), and a combined treatment of both. All remineralization agents were applied in remineralization cycle 2 times a day for 1 week.Measurements made from the enamel samples at the baseline, after demineralization and remineralization procedures evaluated with the OCT (Topcon3D OCT-1 Maestro) and ultrasonic system (Novascope 4500:NDT) lesion depths were measured. The sample surfaces were examined under SEM/EDS (Zeiss EVO-MA10) at x1000, 2500, 5000 and 10000. Data were analyzed in R program with WRS2. Two-way Robust Anova, Benferroni Test, and ICC (Intra-Class Correlation Coefficient) was used to examine the agreement between measurements. Significance level was set at p<0.05. Results: There was no statistical difference between the groups in OCT (p=0.884) and Ultrasound (p=0.051) median values after the protocols. In both measurement methods, the effect of remineralization treatments was statistically significant for lession depth (p<0.01). OCT median values were 104.01 in baseline, 144.78 in post-demineralization, and 90.5 in post-remineralization. Ultrasound median values were 1.34 in baseline, 1.1 in postdemineralization, and 2.36 inpost-remineralization. The highest ultrasound median value was obtained in the Remin Pro+ICON after remineralization (2.67), while the lowest value was obtained after demineralization (1.04). As a result of EDS analysis, the lowest Ca ratio (%atomic) was observed on the grup 5-ICON applied enamel surface (9.35). Conclusion: Although there is no significant difference between the groups, all groups were found efficient for remineralization treatments according to OCT, Ultrasound, and SEM/EDS analysis.Publication Metadata only Effect of Polyethylene Fiber on Fracture Resistance of Bulk-fill Composites(2023-07-03) MANAV, AYBİKE; DOĞU, BENGÜ; YILMAZ ATALI, PINAR; KAHRAMANOĞLU, ERKUT; ŞENOL, AYŞE ASLI; TARÇIN, BİLGE; TÜRKMEN, CAFER; MANAV ÖZEN A., DOĞU KAYA B., YILMAZ ATALI P., KAHRAMANOĞLU E., ŞENOL A. A., TARÇIN B., TÜRKMEN C.Introduction: The aim of this in vitro study was to evaluate the fracture resistance of sonic-activated SonicFill3 (SF) (Kerr) and flowable Charisma Bulk Flow ONE (CO) (Kulzer) bulk-fill composites with or without polyethylene-fiber (R) (Ribbond) application. Materials and Methods: Class I cavities (2x2x4mm) were prepared on 40 freshly extracted human premolars of similar size and classified randomly into 4 groups (SF, SF+R, CO, CO+R). The remaining wall thicknesses of the teeth was confirmed to be 2mm. Ribbond fiber (2x2mm) was applied to cavity bases of the acryl-embedded teeth according to manufacturers’ instructions and OptiBond (Kerr) (for SF, SF+R groups) and Gluma Bond (Kulzer) (for CO, CO+R groups) universal adhesives were used. All specimens were restored in a 4mm monolayer with SF and CO. Valo Cordless (Ultradent) LED-curing unit with a power output of 1000 mW/cm2 was preferred for polymerization. Finishing and polishing were completed with the last 2 stages of Sof-Lex discs (Kerr). Restored teeth were stored in distilled water at 37°C for 24 hours. Fracture resistance (FS) and elastic modulus (EM) values were measured with a universal testing device (Shimadzu AG-X, Shimadzu Corp, Japan). Data were analyzed with IBM SPSS V23 using Independent samples T-test. The significance level was set at p<0.05. Results: No statistically significant difference was found between the bulk-fill composites (SF and CO) without R (p=0.167). Similarly, no significant difference was detected between the Ribbond fiber applied groups (SF+R and CO+R) (p=0.994). The effect of fiber application on FS of SF (p=0.421) and CO (p=0.552) was not statistically significant. The mean maximum force values (newtons) in decreasing order were CO (761.09±224.32) > SF+R (671.08±150.51) > CO+R (669.95±358.44) > SF (580.7±269.04). The EM values of SF and CO were statistically significantly different (p=0.009). A statistically significant difference was observed between the EM values in the Ribbond fiber applied groups (SF+R and CO+R) (p=0.026). EM values of CO were statistically significantly higher regardless of Ribbond application (p<0.001). Conclusion: Within the limitations of this in vitro study, the application of SonicFill3 and Charisma Bulk Flow ONE composites with Ribbond may be an option for clinical applications.
