Phosphoric acid as a conditioning agent in the Gluma bonding system.

摘要: Purpose To investigate the effect of phosphoric acid conditioning gels on compatibility with Gluma dentin bonding system. Materials and methods Sheer bond strengths (BS), marginal performance in cavities microleakage resistance mixed were used as target parameters to determine efficacy Gluma/Pekafill pretreated conditioners 5, 10, 20 or 35% H3PO4 different amounts silica (0, 5 10%) after 15, 30 60 120-second treatment duration. The thicknesses hybrid layers determined along cavity margin by light microscopy. Results Neither concentration content nor times tested had a significantly SBS (P > 0.05). There was no relationship between layer thickness either. recorded same order magnitude previously found etched enamel (+/- 17 MPa). results thermocycling proved adequate sealing. Phosphoric etching is compatible gluma
