- PublicationMetadata onlyEffect of titanium dioxide nanotubes on the mechanical and antibacterial properties of the low-viscosity bulk-fill composite(2021-10-01T00:00:00Z) ÖZLEN, RÜMEYSA HATİCE; DALKILIÇ, Evrim; KÜÇÜKYILDIRIM, Bedri Onur; AKDOĞAN EKER, Ayşegül; Topcuoglu, Nursen; Kulekci, Guven; ÖZLEN, RÜMEYSA HATİCE; DALKILIÇ, EVRIMThe purpose of this investigation is to determine the impact of titanium dioxide nanotubes (TiO2-n) on the mechanical and antibacterial properties of bulk-fill composite resin. 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.
- PublicationMetadata onlyAn Alternative Adhesive Strategy to Optimize Bonding to Root Dentin(2011-10-01T00:00:00Z) Belli, Sema; Cobankara, Funda Kont; Ozcopur, Betul; Eliguzeloglu, EVRİM; Eskitascioglu, Gurcan; DALKILIÇ, 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.

- PublicationMetadata onlyEffect of different disinfectant methods on the initial microtensile bond strength of a self-etch adhesive to dentin(2012-07-01T00:00:00Z) Arısu, Hacer Deniz; Kivanc, Bagdagul Helvacioglu; Uctasli, Mine Betul; Ömürlü, Hüma; DALKILIÇ, EVRIMThe aim of this in vitro study was to evaluate the effect of different disinfection methods on the initial microtensile bond strength of a two-step, self-etch adhesive to dentin. 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.
