Abstract

Aims of the study: To identify the must appropriate type of dental stone produces
with minimal setting expansion
Materials and methods: Three typee of dental stone compared, two groups
produced depending on the mixing ratio so that the setting expansion values obtained
by the aids of extensometer then compare them statistically.
Results and discussion: Comparing setting expansion within each group the
lowest setting expansion found in Elite model stone while the highest value in Silky
Rock model, in Q.D. dental stone While comparing the two groups with each other
shows no considerable changes take place due to increase in the W/P ratio
Conclusion: Increasing the W/P ratio to a considerable limit results in a minimal
changes in the setting expansion for Silky Rock stone, while for Q.D. dental stone &
Elite model the setting expansion decreased. Heat generated from the mixture didn't
affected by the changes in W/P ratio.
