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 .
The effect of various surface contaminants on the microleakage of two different generation bonding agents: A stereomicroscopic study
Aim : The aim of this in vitro study was to evaluate the microleakage of two different generation bonding agents in the presence of various surface contaminants . Material s and Methods : Class V cavities were prepared on 150 extracted human permanent molars . The sample s were r and omly divided into two main groups of 75 teeth each . Group I : Fifth generation bonding system ( Single Bond , 3 M ) . Group II : Seventh generation bonding system ( iBond , Kulzer ) . Subgroups were formed according to exposure to different surface contaminants ( saliva , blood , caries disclosing agent and haemostatic agent ) . Cavities were restored with hybrid composite ( Z-100 , 3 M ) and evaluated for microleakage . The scores were subjected to ‘ t ’ test and analysis of variance ( ANOVA ) test . Results : Single Bond and iBond did not provide complete resistance to microleakage when there was no contamination . Microleakage was minimum in the no contamination subgroup and maximum with the haemostatic agent subgroup for both the groups . Conclusion : Single bond showed lesser micro leakage in contaminated conditions
