Scanning electron microscopy revealed partial removal of the smear layer or an etching effect of dentin as a result of the application of hemostatic agents on dentin .
PRACTICAL IMPLICATION S Adhesive procedures may be affected adversely when performed on dentin and enamel contaminated by hemostatic agents .
Hemostatic agents may induce changes in the dentin surface morphology .
The results of this review indicate that the bond strength of self-etching adhesive systems is affected more negatively than is that of etch- and -rinse systems .
BACKGROUND Hemostatic agents have been used clinical ly in dentistry for many years to control bleeding .
Do blood contamination and haemostatic agents affect microtensile bond strength of dual cured resin cement to dentin?
Objective : The purpose of this study was to evaluate the effects of blood contamination and haemostatic agents such as Ankaferd Blood Stopper ( ABS ) and hydrogen peroxide ( H2O2 ) on the microtensile bond strength between dual cured resin cement-dentin interface . Material and Methods : Twelve pressed lithium disilicate glass ceramics were luted to flat occlusal dentin surfaces with Panavia F under the following conditions : Control Group : no contamination , Group Blood : blood contamination , Group ABS : ABS contamination Group H2O2 : H2O2 contamination . The specimens were sectioned to the beams and microtensile testing was carried out . Failure modes were classified under stereomicroscope . Two specimens were r and omly selected from each group , and SEM analyses were performed . Results : There were significant differences in microtensile bond strengths ( µTBS ) between the control and blood-contaminated groups ( p<0.05 ) , whereas there were no significant differences found between the control and the other groups ( p>0.05 ) . Conclusions : Contamination by blood of dentin surface prior to bonding reduced the bond strength between resin cement and the dentin . Ankaferd Blood Stoper and H2O2 could be used safely as blood stopping agents during cementation of all-ceramics to dentin to prevent bond failure due to blood contamination
