| Summary: | Purpose: The aim of this study was to investigate
the micro tensile bond strength of a self-etch
adhesive system following 1 year storage in water.
Materials and Methods: 10 sound human molar teeth
were used for micro tensile bond strength test. Twostep
self-etch dentin adhesive (Clearfil SE Bond®)
was applied to the flat dentin surfaces according to
the manufacturer’s instructions. Composite blocks (Z-
250; 3M ESPE) of 5 mm in height have been prepared
by using layering technique. Teeth were stored in water
for 24 hours at 37°C and longitudinally sectioned
to obtain dentin sticks of 1 mm2.Randomly selected
samples from half of the teeth were immediately
subjected to micro tensile test and. Remaining
specimens were tested after 1 year storage in water.
Bond strengths were calculated in megapascal (MPa).
Results: Means and standard deviations of the
Clearfil SE Bond® micro tensile bond strength values
were, respectively, 37.31 ± 13.77 MPa and 24.78 ±
2.99 MPa after 24 h and 1 year of storage in water.
The difference was statistically significant (p=0.031).
Conclusion: Long-term storage in water decreased
the micro tensile bond strength values of the twostep
self-etch adhesive which has been accepted
as the gold standard in bond strength tests. |
