Purpose: The purpose of thisstudy was to evaluate the microleakage  and depth of penetration of four recently available pit & fissure sealants. Methods: Fourty sound extracted human molars were randomly divided into 4 groups(N=I0). After sealant placement, the teeth were stored in simulated  saliva for 7 days and thermocycled (500 cycles; 5oC, 37oC and 55oC), isolated, immersed in 5%  methylene blue dye for 24 hrs,subsequently embedded in acrylic resin and sectioned longitudinally in a buccolingual direction The sections were analyzed for leakage using an stereomicroscope. Microleakage was assessed using a dye penetration scoring system (scare=0-3) and also measured in millimetres. Result: All materials exhibited a similar pattern of penetration into the pits and fissures, and no statistically significant difference between the study groups was found. (p>0.05). Microleakage was found to be highest for the flowable giomer, and least for the Gic Fuji VII. Conclusion: Under the conditions used in this in vitro study the flowable giomer, showed higher microleakage depth while micro leakage of Gic Fuji VII was comparatively better.
