Tensile bond strength of composite luting cements to metal alloys after various surface treatments. Indian Journal of Dental Research. 2009 Apr-Jun; 20(2): 174-179.http://imsear.searo.who.int/handle/123456789/139709Aims: To evaluate the effects of two different surface treatments and bonding agents on tensile bond strength between a Co-Cr and a Ni-Cr cast alloy and two resin-luting cements. Materials and Methods: Two hundred and forty alloy samples were cast and subjected to surface treatments such as sandblasting, chemical etching, and sandblasting plus chemical etching. Panavia F and CandB cement were used as cementing mediums. The etching qualities were examined by a stereooptic microscope. Failure surfaces were examined throughout scanning electron microscopy. The data were evaluated using statistical methods, namely analysis of variance and multiple comparison test (Tukey HSD). Results: Significant differences were found in the bonding provided by the various cements (P < 0.001) and also type of surface treatments (P < 0.001). For all groups, sandblasted surfaces showed the highest bond strength values. There was no significant difference between the Cr-Co and the Cr-Ni alloys (P > 0.05). Conclusions: Panavia F showed higher tensile strength and the sandblasted samples possessed higher tensile strength.enAdhesionmetal casting alloyssurface treatmentAcid Etching, Dental --methodsAdhesivenessAluminum Oxide --chemistryBoron Compounds --chemistryChromium Alloys --chemistryCobalt --chemistryComposite Resins --chemistryDental Alloys --chemistryDental BondingDental Etching --methodsDental Polishing --instrumentationDental Polishing --methodsHumansMaterials TestingMethacrylates --chemistryMethylmethacrylates --chemistryMicroscopy, Electron, ScanningNickel --chemistryResin Cements --chemistryStress, MechanicalSurface PropertiesTemperatureTensile StrengthTime FactorsWater --chemistryArticle
