Abstract

The purpose of this study was to evaluate the pH characteristics of the setting alginate impression materials from time of mix to final set.
The test materials included four commercially available fast-setting alginate impression materials (AP, ID-I, PC-I and SM-I) and ten normal-setting alginate impression materials (AG, AR, CC, ID-II, JT, KG, PG, PC-II and T3) were tested in vitro to determine the changes in pH values with time.
From the experiments, the following results can be drawn:
1. The pH changes of the alginate impression materials showed considerable difference according to the products.
2 The pH value of the fast-setting type of alginate impression materials_ was lower, than that of the normal setting types.
3. The data showed that the pH value of the alginate impression materials appeared to be accept-able biocompatable performance.
