    Aim: The aim of this in-vitro study was to evaluate surface roughness (SR) of two different composite resins after toothbrushing with different whitening toothpastes.Materials and Methods: Filtek Z250 universal composite resin (3M) (3M ESPE, St. Paul, MN, USA) containing bis-GMA and Charisma Topaz (CT) nano-hybrid composite resin (Heraeus Kulzer, Wehrheim, Germany) without bis-GMA were used in the study. 50 disc-shaped specimens of 10 mm in diameter and 2 mm in thickness were prepared from each composite. The prepared discs were kept at 370C for 24 hours and then separated in 5 subgroups: G1 control (artificial saliva) group, G2 Colgate Optical White Active Charcoal (containing active carbon), G3 Yotuel (containing carbamide peroxide), G4 Opalescence (containing abrasive particle), and G5 Sensodyne, Promine (containing fluoride) pastes (n = 10).After initialmeasurements and SR1 values were recorded.The discs were brushed in continuous mode with an electric toothbrush (Triumph Professional Care, Oral B Braun GmbH, Kronberg / Ts., Germany) in a slurry (1:3 g/ml) of the tested toothpastes (1.5 N). Samples were brushed twice a day for 4 weeks and 8 weeks to mimic the daily routine. Samples were conserved in artificial saliva between brushing cycles. After 4 weeks and 8 weeks cycles, SR2 and SR3 values were recorded. The obtained data were analyzed by three-way mixed ANOVA.Results: There were no statistically significant differences between the two composite resin materials (p=0.575). When the whitening dentifrices groups were compared f o r both ma t e r i a l s , there was no statistical difference after 4 weeks and 8 weeks. The SR value of the control groups (0,948 ± 0,118 3M, 1,006 ± 0,187 CT) were significantly lower than the Charcoal groups (1,672 ± 0,314 3M, 1,653 ± 0,265 CT) at the end of 8 weeks (p<.05).Conclusion: After simulated brushing with whitening toothpastes, similar degree of roughness was observed on the composite resins tested.Keywords: surface roughness, toothbrushing, whitening toothpaste, resin composite

    Effects of Vitamin C on Surface Roughness, Microhardness and Color Stability of Composite Resins
    (2021-09-16T00:00:00Z) Sarıalioğlu Güngör, Ayça; Değer, Ceren; SARIALİOĞLU GÜNGÖR, AYÇA
    Objectives: The study assessed the changes in color stability, surface roughness and microhardness of three esthetic composite-resin materials after immersed in different effervescent vitamin C tablets.Methods: Three different types of composite resins were investigated: supra-nano hybrid composite, microfilled hybrid composite, and nanofilled composite resins. Ninety disc-shaped specimens (4-mm diameter, 2-mm thickness) were fabricated using Teflon mold and divided into three groups according to the immersion solution (Redoxon, Sambucol, and distilled water as control) for both composite resins (n=10). The top surface of specimens was ground with 600 grit silicon carbide paper for the standardization. Each group was immersed in the solutions for 24 hours. Surface roughness (Ra, mm) was measured by contact profilometer, while the hardness was measured by Vickers hardness (HV) test. CIE L*a*b* coordinates were recorded by using spectrophotometer and color difference analysis (ΔE) was made using the CIEDE-2000 formula. Data were statistically analyzed using two-way ANOVA and Bonferroni correction test (p<0.05).Results: No significant differences in surface roughness change were recorded according to the immersion solutions for both composite resin groups (p>0.05). However, there were significant differences in ΔHV of all composite resins among the control group and the effervescent vitamin C tablets (p<0.001). Highest microhardness decrease was obtained in supra-nano hybrid composite specimens when immersed in Redoxon (-8.49±1.62). Statistically significant differences (p<0.001) were found between the composite specimens immersed in the solutions in terms of ΔE values. Redoxon appeared to be associated with the most severe alteration in color (4.86±0.63).Conclusions: Using vitamin C effervescent tablets did not have a significant change in the surface roughness values of the composite resins. However, microhardness values of all composite resin specimens were reduced. Clinically unacceptable discoloration was observed only in micro-filled hybrid composite specimens immersed in Redoxon.
