Evaluation of the Effect of Physically Magnetized Water on Some Properties of Dental Stone


to study the effect of interaction of dental stone with tap water and physically magnetized water on two periods of time 24h. and 12h to study the change in the physical properties of final product. Materials and Methods: We started prepair no. of control samples and other of samples interacted with physically magnetized water for two periods of time 24h and 12h, then we studied the liner setting expansion and compressive strength.. Results: results obtained from comparing control sample with that treated with physically magnetized water showed an increase in the compressive strength of physically magnetized group and decrease of linear setting expansion in comparison with that of control sample. Conclusion: Reaction of dental stone with physically magnetized water lead to change in some physical properties of dental stone.
