title: The influence of contamination on the bond strength of an etched resin-bonded retainer.
abstract: This investigation examines the influence of potential sources of contamination on the resin bond strength of a base metal alloy. Sixty specimens were cast in a base metal alloy and etched. Composite resin cylinders were bonded to six groups of ten specimens each and tested for shear bond strength using a testing machine at a strain rate of .5 mm/min. Five of the test groups received a different set of treatments, and one of the test groups was a control group. An analysis of variance disclosed no significant differences in bond strengths among any of the test groups at a level of P less than .05.
