The Effect of Adding Some Chemical Materials on The Water

  • 1. University of Mosul, IRAQ

Description

The aims: To determine the effect of some chemical materials on the 
water powder ratio of dental stone. Material and Methods: Three types of chemical 
materials (rosin, nigella stavia oil and sodium lauryl sulfate) were incorporated into 
three kinds of type III dental stone (Zeta, Elite and Dental stone) at four 
concentrations (0.5%, 1%, 1.5% and 2%). The collected data of water powder ratio 
were subjected to the descriptive analysis (mean and stander deviation), student T 
test (to evaluate the difference between standard and experimental groups) and 
one-way analysis of variance (ANOVA) (to show if there are significant 
differences among experimental groups). Results: Revealed that the incorporation 
of these chemical materials into each type of dental stone resulted in changing their 
evaluated water powder ratio; this change varies with the type, concentration of the 
added chemical material and type of dental stone being used. Conclusion: The most 
pronounced effect of the chemical additives that used in this study on the water 
powder ratio of the experimental dental stones was achieved with the addition of 
sodium lauryl sulfate.
