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 The effect of immediate dentin sealing with chlorhexidine pretreatment on the shear bond strength of dual-cure adhesive cement(2021-07-01T00:00:00Z) DENİZ, ŞULE TUĞBA; OĞLAKÇI, Burcu; Yesilirmak, Sevda Ozturk; DALKILIÇ, Evrim; DENİZ, ŞULE TUĞBA; OĞLAKÇI, BURCU; DALKILIÇ, EVRIMThe purpose of this in vitro study was to evaluate the effect of immediate dentin sealing (IDS) with and without chlorhexidine (CHX) pretreatment on the shear bond strength (SBS) of dual-cure adhesive resin cement. Mid-coronal dentin surfaces were obtained from 75 human molars. They were randomly allocated into five groups in accordance to type of IDS [etch&rinse/ER (Adper Single Bond2) and universal/U adhesive systems (Single Bond Universal)] and presence of CHX application (n = 15): Group ER; Group ER + CHX; Group U; Group U + CHX; and Group C (no IDS). Dual-cure adhesive resin cements were bonded with a cylinder-shaped Teflon mold. The SBS was measured using a universal test machine. Fracture type was evaluated with stereomicroscope. The resin/dentin interfaces were examined with an environmental scanning electron microscope. Data were statistically analyzed with two-way analysis of variance and Bonferroni tests (p .05). Group U + CHX showed significantly higher SBS than Group C (p .05). The prevalent failure mode was the mixed type for most of the groups. Group C exhibited an intact and regular hybrid layer with no resin tag, whereas longer and clear resin-tag formation was visible for Group U + CHX. CHX pretreatment improved the bond strength between adhesive resin cement and dentin when IDS treatment was performed with a universal adhesive system.Publication The shear bond strength of repaired high-viscosity bulk-fill resin composites with different adhesive systems and resin composite types(2019-07-18T00:00:00Z) OĞLAKÇI, Burcu; Arhun, Neslihan; OĞLAKÇI, BURCUPublication How does antiseptic mouthwashes against SARS-COV-2 affect the bond strength of universal adhesive to enamel?(2021-12-01T00:00:00Z) Özduman, Zümrüt Ceren; Oğlakçı, Burcu; Doğan, Miraç; Değer, Ceren; Dalkılıç, Evrim; ÖZDUMAN, ZÜMRÜT CEREN; OĞLAKÇI, BURCU; DOĞAN, MİRAÇ; DEĞER, CEREN; DALKILIÇ, EVRIMPublication Smoothielerin nano kompozit rezinlerin mikrosertlik ve renk değişimi üzerine etkisi(2021-03-01T00:00:00Z) Oğlakçı, Burcu; Fazlıoğlu, Leyla; Tunç, Ayşenur; Özduman, Zümrüt Ceren; Dalkılıç, Evrim; OĞLAKÇI, BURCU; FAZLIOĞLU, LEYLA; TUNÇ, AYŞENUR; ÖZDUMAN, ZÜMRÜT CEREN; DALKILIÇ, EVRIM
