Dimensional Stability Analysis of Different Types of Alginate

Irreversible hydrocolloids, or simply alginates, are the most used molding materials in different areas of dentistry, due to their ease of handling, low cost and good reproducibility. The present work aims to analyze the dimensional stability of different types of alginates at different time intervals. It is applied research, in which its approach was qualitative-quantitative, of an exploratory nature. Three different brands of alginate were used, where a standard dummy was molded and the leakage happened immediately: G1 (n: 10) Hydrogun, G2 (n: 10) Jet Plus and G3 (n: 10) Ava gel. With the digital caliper, the distances were measured and compared with the standard model, the data obtained were tabulated, analyzed using parametric tests and the areas of each model were added. As a result, the area of the standard model was similar in both groups. It is possible to conclude that the type of alginate did not interfere with the distortion of the standard model.
