[Intrapulpal temperature change during the setting reactions of various dental cements].

Mixing of certain types of dental materials may produce pulpal injury due to a series of chemical reactions giving way to an exothermic reaction. Three different dental cements; zinc phosphate, polycarboxilate and glass ionomer cements which may increase the intrapulpal temperature were investigated in the present study. The cements were mixed according to the manufacturers' instructions in one group, the liquid and powder ratios were increased by one portion in the other two groups. The intrapulpal temperature changed between 1.32-4.54 degrees C among the three test groups. The intrapulpal temperature rise was markedly influenced when the amount of powder and liquid ratios were changed.
