Effect of Addition of Organic Sweet Corn Flour (Zea Mays L. Saccharata) Against Setting Time Test For Alginate

Abstract

Alginate is one of the most frequently used dental materials; and alginate impression is a simple, cost-effective, and indispensable part of dental practice. However, alginate impression material is still difficult to find in remote areas, this is due to the distance factor and the limited supply of alginate. One of the substitutes for alginate is sweet corn that contain polysaccharide a and are easily available in Indonesia. . This type of research is a laboratory experimental study using 4 groups, consisting of the first group as a control group, namely alginate without being given a mixture of sweet corn flour (10 g). The second group with 60% alginate percentage (6 g) sweet corn flour 40% (4 g) . The third group alginate percentage 55% (5.5 g) sweet corn flour 45% (4.5 g). The fourth group was 50% alginate (5 g) 50% sweet corn flour (5 g). Each group consists of 6 samples. The results of this study were then analyzed using One Way Anova to see if there were differences in each treatment group, the results showed that there were significant differences (p <0.05) in each group. This study also found the group with the fastest setting time, namely the control group, with an average of and the longest setting time is in group 3 with an average of 234 seconds . This can happen because of the polysaccharide content, namely amylopectin in sweet corn flour. The conclusion of this study is that sweet corn flour ( Zea mays L. Saccharata ) can be used as an alginate mixture because it has a setting time according to the American Dental Association (ADA ) standard, which is 2 - 4.5 minutes.
