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.
 
Keywords: Microleakge, silorane based composite, silver nitrate staining
