Bond strength of an adhesive system to dentin contaminated with hemostatic agents

37710

Objectives: The aim of the present study was to evaluate the microtensile bond strength (μTBS) 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 0C 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 (α=0.05). Results: μTBS 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 μTBS of groups (p 0.05). Conclusions: Contamination of dentin with hemostatic agents didn’t affect the μTBS of self-etch a dhesive system. Hemostatic agents may be used to control bleeding without decreasing μTBS of self-etch adhesive system
