title: A study of variables affecting the impinging jet method for measuring the erosion of dental cements.
abstract: An examination has been made of factors affecting the results obtained from the impinging jet method for evaluating the durability of dental cements. These included intrinsic factors i.e. the powder/liquid ratio used in the mix and the cure time of the cement and extrinsic factors i.e. the pH, ionic strength and temperature of the test solutions. The method was found to be sensitive to test conditions. The initial rate of erosion was found to be essentially constant.
