Artificial CAD were obtained. Half of the specimens were pretreated with 2%CHX andhalf of them received no-pretreatment before the application of indirect pulp capping materials(n=15). Five materials were assessed: 1-Conventional glass ionomer cement (Fuji IX, GC, Japan)(CGIC) 2-Resin modified glass ionomer cement (Fuji II GC, Japan) (RMGIC), 3-Resin modified glassionomer bioactive cement (Activa Bioactive, Pulpdent, USA) (ACT) 4-Resin modified tricalciumsilicate (Theracal, Bisco, USA) (RMCS), 5-Water-based tricalcium silicate, (Biodentine, Septodont,France) (WBCS). To evaluate the SBS, the Universal Test machine was used (1mm/min).Data were evaluated by Student’s t-test and one-way ANOVA. The differences betweengroups were analyzed by Mann-Whitney U and Kruskal-Wallis test. Pairwise comparisons weredetermined with the post-hoc Tukey HSD or Dunn-Bonferroni test. Unless otherwise stated,results for p<0.05 were considered statistically significant. Bonferroni Correction was made tocontrol Type I error in multiple comparisons.Results: Among the groups without pretreatment; SBS of RMCS [0.72(0.59-1.09) MPa] and WBCS[0.89 (0.31-1.05) MPa] were found to be significantly lower compared to ACT [4.37(3.34-6.45) MPa],CGIC [2.52(1.88-6.36) MPa] and RMGIC [5.24(3.23-8.27) MPa] (p<0.01). There were no significantdifferences between Group ACT, CGIC and RMGIC and between Group RMCS and WBCS(p>0.05).Among the CHX pretreated samples, SBS of Group RMCS [0.43(0.14-0.86) MPa] and WBCS[0.21(0.16-0.35) MPa] were found to be significantly lower than Group ACT [4.33(2.68-7.06) MPa],CGIC [4.36(3.61-7.44) MPa] and RMGIC [7.56(6.38-10.29) MPa] (p<0.01). There were no significantdifferences between Group ACT, CGIC and RMGIC and between Group RMCS and WBCS (p>0.05).There was no statistically significant difference between the groups with and without CHXpretreatment in all materials (p>0.010) except for WBCS. CHX pretreated WBCS group showedlower SBS than the WBCS/without CHX (p=0.007).Conclusion: Tricalcium silicate-based materials had lower shear bond strength than glassionomer-based materials, both with and without pre-treatment of CHX.*This study was funded by Scientific and Technological Research Council of Turkey (TUBITAK)(ProjectNo:119S048)Keywords: indirect pulp capping material, shear bond strength, caries affected dentinPublication Metadata only Evaluating the Effects of Different Remineralization Agents on Initial Enamel Lesions In Vitro(2022-04-23T00:00:00Z) Sarıalioğlu Güngör, Ayça; Dalkılıç, Evrim; Alkan, Elif; Yılmaz Atalı, Pınar; Dağtekin, Dilek; SARIALİOĞLU GÜNGÖR, AYÇA; DALKILIÇ, EVRIMPublication Metadata only Effect of TiO2-n on the Antibacterial Properties of Low – Viscosity Bulk - Fill Composite(2021-04-22T00:00:00Z) Topcuoğlu, Nursen; Dalkılıç, Evrim; Küçükyıldırım, Bedri Onur; Akdoğan Eker, Aysegül; Külekçi, Hatice Güven; DALKILIÇ, EVRIMPublication Metadata only Çalışma adı: Farklı Bitim ve Polisaj Sistemlerinin Alkasitin Yüzey Pürüzlülüğüne Etkisi(2022-10-01T00:00:00Z) Fidan, Reyhan; Sagun, Ayşe Alanur; Oğlakçı, Burcu; Özduman, Zümrüt Ceren; Dalkılıç, Evrim; FİDAN, REYHAN; OĞLAKÇI, BURCU; ÖZDUMAN, ZÜMRÜT CEREN; DALKILIÇ, EVRIMPublication Metadata only premolar cuspal deflection restored with dual-cure composites using different power-irradiances(2018-09-07T00:00:00Z) Oğlakçı, Burcu; Dalkılıç, Evrim; OĞLAKÇI, BURCU; DALKILIÇ, EVRIMPublication Metadata only Class V kompozit restorasyonların hacimsel polimerizasyon büzülmesinin ve gap oluşumunun değerlendirilmesi: mikrobilgisayarlı tomografi analizi(2019-12-08T00:00:00Z) Oğlakçı, Burcu; Özduman, Zümrüt Ceren; Dalkılıç, Evrim; OĞLAKÇI, BURCU; ÖZDUMAN, ZÜMRÜT CEREN; DALKILIÇ, EVRIMPublication Metadata only Effect of Povidone-Iodine and Hydrogen-Peroxide Mouthwashes on Shear Bond Strenth to Enamel(2021-04-22T00:00:00Z) Doğan, Miraç; Değer, Ceren; Özduman, Zümrüt Ceren; Oğlakçı, Burcu; Dalkılıç, Evrim; DOĞAN, MİRAÇ; DEĞER, CEREN; ÖZDUMAN, ZÜMRÜT CEREN; OĞLAKÇI, BURCU; DALKILIÇ, EVRIMAim: During COVID-19 pandemic, use of different mouthwashes have been recomended toreduce the viral load. Aim of this study is to compare the effect of different mouthwashes onshear bond strength of a universal adhesive in regard to self-etch (SE) and etch and rinse (ER)application modes.Materials and Methods: 100 sound human maxillary central incisors were selected. Flat enamelsurfaces were obtained. Specimens were randomly assigned to 5 groups (n=20) [Control, 1.5%hydrogen-peroxide(H2O2), 0.2% povidone-iodine (PVP-I), Listerine, Chlorhexidine (CHX)]. Then,each group was divided into two subgroups according the application mode of the useduniversal adhesive (Single Bond Universal) (n =10). After adhesive procedures, resin compositewas applied by a Teflon mold (2mm height, 2.4mm diameter) and light polymerized. Shear bondstrength was tested with a Universal testing machine after water storage for 24 h. The debondedareas were examined for failure mode analysis with a stereomicroscope at 25×magnifications.The data were statistically analyzed by two-way ANOVA and Bonferroni test (p<0.05).Results: Etch and rinse application mode of the adhesive system led to higher shear bond strengthsthan self-etch application mode, regardless of the preoperational antiseptic mouthwashes used(p<0.001). The lowest shear bond strength values among all the tested groups were measuredfor H2O2/SE group (3.77±1.37MPa). The control group (where no mouthwash was used) exhibitedthe highest SBS values (26.43±4.35MPa) in SE mode (PVP-I/SE=8.70±1.92, Listerine/SE=9.99±2.90;CHX/SE=17.67±4.37MPa) (p<0.05). PVP-I/ER group (24.04±5.01MPa) showed no significantdifference with H2O2, CHX, Listerine and control groups in ER mode (21.40±3.67, 28.30±6.03,29.61±4.78, 31.48±7.45) (p>0.05). H2O2 presented lower shear bond strength (21.40±3.67MPa) thanother mouthwashes in ER mode (p<0.05). The adhesive failure mode was predominant for allgroups.Conclusion: The antiseptic mouthwashes decreased the enamel bond strength of the universaladhesive used in self-etch application mode, however only H2O2 reduced the enamel bondstrength in both application modes.Keywords: hydrogen peroxide, mouthwash, povidone iodine, shear bond strength, chlorhexidine
