    Bond strength of an adhesive system to dentin contaminated with hemostatic agents
    (2014) Güller F.; Şimşek M.; Cebe F.; Yildiz E.; Yildirim C.
    Objectives: The aim of the present study was to evaluate the microtensile bond strength (?TBS) of self-etch adhesive system to dentin surface contaminated with three different hemostatic agents in the presence of blood and saliva. Materials and Methods: Twelve extracted human carious-free permanent molar teeth were used to obtain flat occlusal dentin surfaces. The dentin surfaces were grinded with 600 grid sandpaper under water irrigation. Teeth were divided into four groups (I: Kontrol, II: Ankaferd, III: ViscoStat Clear and IV: Transamine). The hemostatic agents were aplicated in the presence of blood and saliva, then were rinsed and dried. Teeth were restored with self-etch adhesive system (Clearfil SE Bond) 2mm thick composite resin (Quadrant Universal LC). Then specimens were stored 37 °C distilled water during 24 hours. Five microtensile specimens from each tooth measuring 1.00-+ 0.003 mm were prepared with a slow-speed diamond saw sectioning machine with a diamondrim blade (n=15). These specimens were attached to opposing arms of the microtensile testing device with cyanoacrylate adhesive and fractured under tension at a crosshead speed of 1 mm/min. Statistical analysis was made with one-way analysis of variance (ANOVA) and Tukey tests (?=0.05). Results: ?TBS values of groups were (mean ± SD in MPa); I: 28.81±6.84, II: 27.38±4.89, III: 24.89±5.80, IV: 24.73±7.14. There was no significant differences between ?TBS of groups (p>0.05). Conclusions: Contamination of dentin with hemostatic agents didn't affect the ?TBS of self-etch a dhesive system. Hemostatic agents may be used to control bleeding without decreasing ?TBS of self-etch adhesive system.

    Bond strengths of a self-etching adhesive to dentin surfaces treated with saliva, blood, and different hemostatic agents
    (Academy of General Dentistry, 2015) Unlu N.; Cebe F.; Cebe M.A.; Cetin A.R.; Cobanoglu N.
    The aim of this study was to evaluate the microtensile bond strengths of a self-etching adhesive to dentin surfaces after treatment with 4 different hemostatic agents in the presence of saliva and blood. After testing, no significant differences were found between the mean bond strength of Clearfil SE (CSE) Bond resin adhesive to normal dentin and those of CSE to dentin treated with the hemostatic agents ViscoStat Clear, Astringedent, or Astringedent X (P > 0.05). However, the mean bond strength of CSE Bond to dentin treated with Ankaferd Blood Stopper (ABS) was significantly greater than those of the other groups (P < 0.05). Thus, while 3 of the tested hemostatic agents did not have significant effects on the bond strength of composite resin to dentin, ABS increased the bond strength of CSE Bond to dentin.

    Influence of caries detection dye on composites bond strength of carious affected dentin
    (Cumhuriyet University Faculty of Dentistry, 2014) Yalçin M.; Cebe F.; Cebe M.A.; Dündar A.; Öztürk B.; Şengun A.
    Objectives: The aim of this in vitro study was to evaluate effect of three different caries detecting dyes on shear bond strength of a self etch adhesive to caries affected dentin. Materials and Methods: 60 extracted human third molars which are affected by caries used in this study. Occlusal surfaces removed to obtain flat dentinal surfaces and teeth mounted acrylic. Specimens were divided into four groups of 15 to be tested three different caries detecting dyes. First group is control and others Caries Detector, Quadrant Cari Test, Sable Seek groups. In control group decayed dentine tissues remowed with silicon carbite papers (300 gride) and in others groups caries detectors applied and carious dentine tissues remowed with silicon carbite papers. Than dentin bonding systems Clearfil SE Bond applied and specimens restorated with composite resin. All products were used according to manufacturer's instructions. Bond strengths were tested and data were statistically analyzed one-way Analysis of Variance (ANOVA) and Tukey tests. Results: As results of this study, Quadrant Cari Test group showed lower bond strength than other detecting dyes groups. While bond strengths of Caries Detector and Sable Seek groups were similar, their bond strengths were significantly higher than Quadrant Cari Test group (p<0,05). Conclusions: According to the results of this in vitro study caries detecting dyes may lead to increased shear bond strength values obtained.
