MECHANISM OF ACTION AND RELATIVE POTENCY Bisphosphonates are chemical analogues of pyrophosphate. The presence of a carbon rather than oxygen atom at the centre of the molecule prevents its breakdown. The two phosphonate groups are attached directly to the carbon atom from which also extend the R1 and R2 side chains (fig 1). The R1 side chain is usually a hydroxyl group and is often referred to...
UNLABELLED An increase in dentin roughness, associated with surface composition, contributes to bacterial adherence in recontaminations. Surface roughness is also important for micromechanical interlocking of dental materials to dentin, and understanding the characteristics of the surface is essential to obtain the adhesion of root canal sealers that have different physico-chemical characterist...
