Abstract:
The aim of this study was to evaluate the effect of cleansing agents on the shear bond strength I of resin cement and lithium disilicate ceramic after being contaminated with the hemostatic agent. I The specimens were randomly divided into six groups (n=10) according to different treatments on I ceramic surfaces: Group 1 without any surface treatment, Group 2 only applied a silane coupling I agent, Group 3-6 also applied silane coupling agent, followed by a hemostatic agent (Viscostat® I Clear) for 5 minutes and then cleaned with cleansing agents (Group 3 distilled water, Group 4 I phosphoric acid, Group 5 chlorhexidine, Group 6 ethanol). All prepared specimens were bonded I with resin cement (PanaviaTM V5). All bonded specimens were subjected to shear bond strength I measurement using a universal testing machine. The data were statistically analyzed using oneway ANOVA and Tukey's test (a=0.05). The results showed that the shear bond strength of Group I 4-6 had no significant differences in shear bond strength between groups (p>0.05) and were lower I than Group 2, which was the control group but higher than Group 1, the only group without surface I treatment. In conclusion, cleaning hemostatic agent contaminated surfaces of ceramics can restore I shear bond strength between lithium disilicate ceramic and resin cement. Cleaning with water I showed the lowest shear bond strength among other cleansing agents in this experiment. © 2021. All Rights Reserved.
