An in vitro dye leakage study was conducted on one hundred and twenty single rooted human teeth with single root canals to assess the relative microleakage of three retrograde filling materials namely light cure calcium hydroxide, cermet and silver amalgam with and without bevel. Specific retrograde cavities were made and filled. The extent of penetration of 2% methylene blue dye was measured by a travelling microscope. The results showed that cermet had statistically lesser leakage as compared to light cure calcium hydroxide and silver amalgam. There was signifi­cant increase in the leakage as the amount of bevel increased.
