Traditional bonding materials are incapable of bonding in presence of moisture, are challenged by "Moist-field" bonding materials. Claims and counter claims are made regarding their, efficacy to use as ideal orthodontic bonding adhesives. Present study done to compare Shearbondstrength of Ethyl cyanoacrylate(Smart Bond) and self cure acrylic(Rely-a-Bond) under different conditions. Rely-a-Bond and Smart Bond, are acceptable bonding materials in dry and wet conditions respectively with regards to Shear bond strength values per se. Rely-a-Bond showed significant increase in Shear bond strength...
