[Effect of vibration for the rheology of some luting cements].
Vibrant load is known to be effective to thin the film thickness of various luting cements. In this study, a vibrator which can change various conditions such as frequency, form of wave were made, and the changes of viscosity, film thickness and bond strength were tested statistically. Furthermore, the most effective condition for the slurry of some luting cements (i.e. domestic two zinc phosphate cements, one polycarboxylate cement and one glass ionomer cement) were investigated. The results obtained were as follows. 1) When vibrant load was applied to the slurry of cement in the setting process, the rise in viscosity was apt to be slower than the same case of static load. 2) The effect of vibration appears in the early sixty seconds especially, and the effect varied with the kind of cement, frequency or form of wave. 3) Vibration was also effective for the increase of compressive strength and of bond strength.
