Publication Metadata only An Alternative Adhesive Strategy to Optimize Bonding to Root Dentin(2011-10-01T00:00:00Z) Belli, Sema; Cobankara, Funda Kont; Ozcopur, Betul; Eliguzeloglu, EVRÄ°M; Eskitascioglu, Gurcan; DALKILIĆ, EVRIMIntroduction: This study examined the hypothesis that the shear-bond strengths of AH Plus (AH) and Hybrid Root Seal (HRS) to root dentin might be optimized by using a powdered dentin-reinforced bonding procedure. Methods: The surfaces of root halves obtained from extracted human premolars were ground (800-grit silicon carbide paper), treated (5.25% NaOCl 17% EDTA for 5 minutes followed by distilled water) and randomly allocated into two groups according to the sealer and then into three subgroups according to bonding procedure. Dentin particles with a maximum size of 25 mu m were incorporated into the adhesive of Clearfil Liner Bond 2V, and groups were created as follows: no adhesive, adhesive alone, and with powdered dentin reinforced adhesive; 3 x 3 mm high buildups were created using sealer and allowed to set (37 degrees C, 100% humidity, 72 hours). Shear tests were performed (1 mm/min). Data were calculated as MPa and analyzed (two-way analysis of variance, Tukey test). Results: A significant difference was found between the groups (P = .000). Adhesive or reinforced adhesive had a negative effect on the shear-bond strength of AH, but they significantly increased the shear-bond strength of HRS (P = .000). HRS showed a similar bond strength with either adhesive alone or adhesive reinforced with powdered dentin. AH group was characterized by mixed failure, whereas the predominant failure type of the HRS group was cohesive failure within the sealer. Conclusions: Reinforcing adhesive resin with powdered dentin may be considered an alternative for optimizing the bonding of methacrylate-based sealers to root dentin and might affect the shear bond strength.

Twenty mandibular molars were sectioned parallel to the occlusal plane to expose the mid-coronal dentin. All of the teeth were divided into four groups (n = 5 per group): (1) in group OZ, the dentin surfaces were exposed to ozone gas from the Ozonytron X delivery system (OzonyTron X-Bioozonix, Munich, Germany), (2) in group ND, the dentin surfaces were irradiated with an Nd:YAG laser (Pulsmaster 600 IQ, American Dental Technologies, U.S.), (3) in group CHX, the dentin surfaces were treated with a 2% chlorhexidine solution, and (4) in the control group, no treatment was applied. In all of the groups, the teeth were restored with Clearfil SE Bond (Kuraray, Tokyo, Japan) and Clearfil Majesty Posterior (Kuraray, Tokyo, Japan), according to the manufacturer-s instructions. The teeth were sectioned perpendicular to the bonded surface (surface area of approximately 1 mm(2)). Thus, six to seven specimens were obtained from each tooth, and a total of 34 specimens were analyzed in each group. The specimens were attached to the microtensile test machine (Micro Tensile Tester, T-61010 K, Bisco, U.S.). The data was analyzed using the one-way analysis of variance (ANOVA) and Tukey test (p < 0.05). Fracture modes of each specimen were determined using a stereomicroscope (SZ-PT Olympus, Tokyo, Japan) and a scanning electron microscope (SEM). The lowest bond strength occurred in the OZ group. Significant differences were determined only between group OZ and the other groups (group ND, group CHX, and control group) (p < 0.05). In conclusion, although ozone decreased the microtensile bond strength of the self-etch adhesive system to dentin, the Nd:YAG laser and 2% chlorhexidine did not change the microtensile bond strength so in context of the present study it would appear that the Nd:YAG laser and 2% chlorhexidine may be used as pre-restorative sterilization procedures on the dentin prior to the application of a two-step, self-etch adhesive.Publication Metadata only Premolar cuspal deflection with dual-cure composites using different power-irradiances.(2018-08-28T00:00:00Z) KAZAK, MAÄRUR; OÄlakƧı, Burcu; DĆNMEZ, NAZMÄ°YE; DALKILIĆ, EVRÄ°M; KARAHAN, SEVÄ°LAY; DĆNMEZ, NAZMÄ°YE; DALKILIĆ, EVRIMPublication Metadata only Bulk Fill Kompozitlerin Tamirinde Farklı YĆ¼zey PĆ¼rĆ¼zlendirme Ä°Ålemlerinin Makaslama BaÄlanma Dayanımı Ćzerine Etkisi.(2019-09-04T00:00:00Z) Hisarbeyli, Duygu; ĆZLEN, RĆMEYSA HATÄ°CE; DALKILIĆ, EVRÄ°M; KAZAK, MAÄRUR; DĆNMEZ, NAZMÄ°YE; ĆZLEN, RĆMEYSA HATÄ°CE; DALKILIĆ, EVRIM; DĆNMEZ, NAZMÄ°YEPublication Metadata only premolar cuspal deflection restored with dual-cure composites using different power-irradiances(2018-09-07T00:00:00Z) OÄlakƧı, Burcu; DalkılıƧ, Evrim; OÄLAKĆI, BURCU; DALKILIĆ, EVRIMPublication Metadata only Class V kompozit restorasyonların hacimsel polimerizasyon bĆ¼zĆ¼lmesinin ve gap oluÅumunun deÄerlendirilmesi: mikrobilgisayarlı tomografi analizi(2019-12-08T00:00:00Z) OÄlakƧı, Burcu; Ćzduman, ZĆ¼mrĆ¼t Ceren; DalkılıƧ, Evrim; OÄLAKĆI, BURCU; ĆZDUMAN, ZĆMRĆT CEREN; DALKILIĆ, EVRIMPublication Metadata only Fracture Resistance and Failure Modes of Lithium Disilicate or Composite Endocrowns(2018-07-01T00:00:00Z) Altıer, Muhammed; Erol, Funda; Yıldırım, Gulhan; DALKILIĆ, EVRÄ°M; DALKILIĆ, EVRIMPurpose: The aim of this study was to determine the fracture strength of endocrowns made of lithium disilicate ceramic and two different indirect resin composites. Materials and Methods: Forty human mandibular molars were randomly separated into four groups (n = 10 in each group) -Group IN: control group, Group IPS: endocrowns made of lithium disilicate ceramic (IPS e. max CAD, IvoclarVivadent, Schaan, Liechtenstein); Group SL: Endocrowns made of Solidex microhybrid composite (Shofu, Ratingen, Germany); and Group GR: Endocrowns made of Grandia microhybrid composite (GC Europa, Leuven, Belgium). In all of the groups, dual-cure resin cement (Relyx Ultimate Clicker, 3M ESPE, St. Paul, MN, USA) was used to cement the endocrowns. All of the teeth were subjected to fracture by means of a universal testing machine (Instron), and compressive force was applied. The failure type and location after fracture were classified. The data were analyzed using one-way ANOVA, Tukey-s post hoc test, and Chi-square test (P 0.05). In Group SL, 80% of the specimens exhibited favorable fractures; also, 60% of the specimens exhibited favorable fracture in group GR, and only 10% of the specimens exhibited favorable fracture in group IPS. Conclusions: The lithium disilicate ceramic endocrowns exhibited higher fracture resistance than indirect composite groups. Both of the composite endocrowns showed more favorable failure than the lithium disilicate ceramic endocrowns.Publication Metadata only Effect of different LED light curing units on the microhardness values of different bulk fill composites(2017-12-03T00:00:00Z) FÄ°LDÄ°ÅÄ°, MEHMET ALÄ°; DALKILIĆ, EVRÄ°M; KAZAK, MAÄRUR; DĆNMEZ, NAZMÄ°YE; FÄ°LDÄ°ÅÄ°, MEHMET ALÄ°; DALKILIĆ, EVRIM; DĆNMEZ, NAZMÄ°YE
