The purpose of this study was to evaluate the compatibility of dental gypsum with three recently introduced irreversible hydrocolloid (alginate) alternatives. The test materials were AlginotÂ® (Kerrâ„¢), Position Penta QuickÂ® (3M ESPEâ„¢) and SilgimixÂ® (Sultan Dentalâ„¢). The irreversible hydrocolloid impression material, Jeltrate Plus antimicrobialÂ® (Dentsply Caulkâ„¢) served as the control. Materials and Methods: Testing of materials was conducted in accordance with ANSI/ADA Specification No. 18 for Alginate Impression Materials. Statistical Analysis: The 3-Way ANOVA test was used to analyze measurements between different time points at a significance level of (p < 0.05) Outcome: It was found that there was greater compatibility between gypsum and the alternative materials over time than the traditional irreversible hydrocolloid material that was tested. A statistically significant amount of surface change/incompatibility was found over time with the combination of the dental gypsum products and the control impression material (Jeltrate Plus antimicrobialÂ®).
