TiO2-n were synthesized in laboratory conditions using the hydrothermal method. Varying amounts of TiO2-n were included in the bulk-fill composite resin. Microhardness, surface roughness, and the three-point bending test were used to determine the mechanical properties of the composite. After the flexural strength test, the fractured surfaces of the composite resin were examined with a high-resolution scanning electron microscope. The antibacterial activity of Streptococcus mutans (S.mutans) and Lactobacillus Casei (L.casei) was assessed using a direct contact test. The statistical examination was completed using IBM SPSS Statistics 22. Group differences were compared using the Kruskal Wallis and Dunn tests (p 0.05). Adding 0.5% and 1% TiO2-n increased the microhardness of the bulk-fill composite (p 0.05). Though adding TiO2-n did not have an antibacterial impact on S.mutans (p > 0.05), adding 0.5% TiO2-n produced an antibacterial impact on L.casei in daylight (p < 0.05). The addition of 0.5% and 1% TiO2-n increased the microhardness of the top surface of the bulk-fill composite without negatively affecting surface roughness or the composite-s three-point bending properties Adding 0.5% TiO2-n to the composite resin produced an antibacterial impact on L.casei in daylight.Publication Metadata only Effects of Experimental Nanohydroxyapatite and Er:YAG Laser on Dentin Hypersensitivity(2022-09-15T00:00:00Z) Åahin, Demet; DeÄer, Ceren; OÄlakƧı, Burcu; Demirkol, Metehan; KĆ¼Ć§Ć¼kyıldırım, Bedri Onur; GĆ¼rsel, Mehtikar; DalkılıƧ, Evrim; ÅAHÄ°N, DEMET; DEÄER, CEREN; OÄLAKĆI, BURCU; GĆRSEL, MEHTÄ°KAR; DALKILIĆ, EVRIMPublication Metadata only Shear Bond Strength of Indirect Pulp Capping Materials to Caries-Affected Dentin(2021-04-22T00:00:00Z) Ćzduman, ZĆ¼mrĆ¼t Ceren; OÄlakƧı, Burcu; DalkılıƧ, Evrim; ĆZDUMAN, ZĆMRĆT CEREN; OÄLAKĆI, BURCU; DALKILIĆ, EVRIMAim: To evaluate the shear bond strength (SBS) of indirect pulp capping materials to cariesaffected dentin (CAD) with/without chlorhexidine (CHX) pretreatment.Materials and Methods: Coronal dentin surfaces of 150 extracted sound human molar teeth wereground flat. 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 Studentās 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 Influence of bulk-fill composite types, shades and light-curing units on microhardness(2020-05-01T00:00:00Z) Ćzdemir, Serife; DalkılıƧ, Evrim; ĆZDEMÄ°R, ÅERÄ°FE; DALKILIĆ, EVRIMPublication Metadata only Evaluating the Effects of Different Remineralization Agents on Initial Enamel Lesions In Vitro(2022-04-23T00:00:00Z) SarıalioÄlu GĆ¼ngƶr, AyƧa; DalkılıƧ, Evrim; Alkan, Elif; Yılmaz Atalı, Pınar; DaÄtekin, Dilek; SARIALÄ°OÄLU GĆNGĆR, AYĆA; DALKILIĆ, EVRIMPublication Metadata only Influence of fiber insertion and different material type on stress distribution in endocrown restorations: a 3D-FEA study.(2021-12-29T00:00:00Z) Yildirim, Gulhan; Demir, Cihan; GĆ¼ven, Melahat Ćelik; KoƧ, Osman; DalkiliƧ, Evrim; DALKILIĆ, EVRIM
