Composite adhesive offers the advantages of early high bond strength
, improved esthetics, increased working time and shorter setting time.
Mean average of dentin bond strength
of adhesive systems for the three evaluation storage times, according to CHX treatment, are showed in Table I.
8] In this study, Zirconomer was used as it is a relatively new material available, there are no studies related to bond strength
with this material comparing it with other GICs.
After the bond strength
test, fractured specimens from each group were observed under the Scanning Electron Microscope (SEM) to evaluate the type of bond failure.
Thereafter, composite cylinders were repaired and prepared to microtensile bond strength
(beams) and divided again into storage periods of 24 hours and 1 year (2 groups) in artificial saliva, as shown in Figure (for a total of 16 groups).
Conclusion: The irrigant solution have a clear influence on the push-out bond strength
of the fiber posts regardless of the cement used.
Mean shear bond strength

8, the interface was clearland loose with the large of cavitationis, and ite bond strength
reached the mimimum; the interface was vague and inseparable with the teared fiber, and ite bond strength
reach the maximum.
For the microshear bond strength
test, zirconia reinforced lithium silicate glass-ceramic (Suprinity, Vita Zahnfabrik, Bad Sackingen, Germany) cylinders with 1 mm in diameter and 1 mm in height were bonded to the enamel and dentin specimens.
It is true that higher molecular weight carbohydrates can provide good bond strength
under dry conditions, but these bonds are greatly weakened by the addition of water (Baumann and Conner 2002).
The values of shear bond strength
were analyzed using SPSS version 16.
Researchers examined properties including compressive strength, shrinkage, splitting tensile bond strength
, and freeze/thaw resistance.
Although many studies have reported a loss in performance, few studies have attempted a method to effectively maintain or enhance the durability of the bond strength
under the exposure.
2002], others have indicated greater bond strength
in primary dentine compared with permanent dentine [Hosoya et al.
EP76M-1 is thermal shock and chemical resistant, exhibits high bond strength
to similar and dissimilar substrates, and provides a thermal expansion coefficient of 30 pin.
