Evaluation of pH changes produced by dental pulp capping materials: An in vitro study

Results. All testing materials had an alkaline pH. Analysis of the pH changes as a function of time showed a gradual rise in the pH of all the materials. Differences in pH values between the first and last experimental period were statistically significant (p < 0.001). The highest pH increase was observed for setting and the lowest for non-setting calcium hydroxide preparations. Based on the obtained results, the preparations were divided into groups relating to their alkaline abilities. The highest pH increase was observed for setting and the lowest for non-setting calcium hydroxide preparations.
