Abstract

Aim: To evaluate, the effect of, various surface contaminants on the microleakage between 7 Generation (G-Bond, GC) and 8 Generation Bonding Agent (G-Premio, GC).
Materials and Methods: Ninety freshly extracted maxillary human premolars were collected for the study. They were randomly divided into two groups (n=45), Group 1-7 Generation and Group 2- 8 Generation. They were further subdivided into 3 sub-groups (n=15): a) Control b) Saliva c) Blood. A Class V cavity was prepared on the buccal surface. Samples of both the groups were applied with bonding agent and according to respective sub-group were contaminated with saliva and blood, before curing the bonding agent, then restored with Composite material. The samples were subjected to thermocycling and prepared for dye immersion. Samples were immersed in 2% Methylene Blue dye for 24 hours and later sectioned buccolingually. Each half of the buccolingually sectioned samples was observed under stereomicroscope under the power of 10x and 40x.
Statistical analysis used: Result was obtained using the Chi Square Test.
Results: In Group 1, minimum microleakage is observed in control group, and maximum in those contaminated with blood. In Group 2, maximum microleakage is observed in samples contaminated with blood and the microleakage in samples of control group and those contaminated with saliva is almost same and less than that observed in blood.
Conclusion: 8 Generation shows better performance than 7 Generation Bonding Agent.
Key Message: Contamination from blood and saliva, during bonding leads to a grave outcome of microleakage, during restoration with composite. But, with newer generation of bonding agents, it seems to be a ray of hope at the dawn of preventing microleakage to quite an extent.
