Abstract:
Backgroud and Aim: microleakge is one of the most common cause of failure in restorative dentistry in this study the microleakge of filtek p90 , filtek p60 was evaluated and compared .
Materials and Methods: In this experimental study, on 48 premolar teeth standardized class II MOD preparations were made cervical margin of mesial preparation were 1mm above the CEJ and 1 mm and the distal preparation were 1 mm below the CEJ Samples divided in to 3 groups of sixteen teeth.
A group: teeth were filled with filtek silorane (3M ESPE , USA) and silorane system adhesive self-etch primer and bond.
B: teeth were filled with filtek silorane and Adper single bond plus.
C: sixteen teeth were filled with filtek p60 and Adper single bond plus.
After AgNO3 dye opplicaiton microleakage were evaluated by stereomicroscope.data were statistically analyzed by kurskal-wallis and Wilcoxon. the level of 0.05 considered significant.
Results: The most enamel microleakage was related to C and lowest enamel microleakge was shown in A group. The most dentin microleakage was related to B and the lowest dentin microleakge was shown in A group. Microleakage was significantly different between A, with B and C (P‹0.05) dentin microleakage was not significant difference between B and C.
Conclusion: Type of composite and bonding effect to microleakage,
the lowest microleakage was gingival margine irrespective of the location of the margine related to group A.
