Abstract
Introduction: Alginate impression material is the most widely used impression material in dentistry. The availability of impression materials in Indonesia is highly dependent on importers, in some remote areas difficult to obtain and limited supplies. To overcome this situation, modification of the impression material is carried out by adding natural ingredients containing certain polysaccharides such as garut flour (Maranta arunidaceae). Objective: The purpose of this study is to determine the effect of mixing alginate impression material with garut flour (Maranta arunidaceae) in terms of setting time. Methods: The research method used experimental laboratories. The setting time value was calculated from the beginning of mixing the impression material until the impression material was no longer attached to the setting time indicator tool. Data were analyzed using ANOVA test followed by Post Hoc Tukey test. Result and Discussion: The results of the ANOVA test showed that the p-value <0.05 indicates that the mixing of alginate impression material and garut flour has a significant effect on the setting time of the impression material. Conclusion: The conclusion of this study is that the higher the percentage of garut flour added to the alginate impression material, the longer the resulting of setting time. The setting time for the modification of alginate and garut flour (Maranta arunidaceae) was according to the standard specifications of the American Dental Association (ADA) (2-4.5 minutes) for normal setting in the mixing groups D, E, and F.
