![]() This combined influence allowed the impression material to undergo the reactions at a faster rate, thereby reducing the material's setting time. Increasing the water temperature used in the preparation added more thermal energy to the system increasing collisions between the reagents while also amplifying their activation energy. This pattern was attributed to Arrhenius kinetics involving collision theory and activation energy as they relate to the chemical reactions occurring when alginate impression material is mixed with water. Mean setting time decreased to 2.39☐.23 minutes when 45☌ water was used.Ĭonclusion: An inverse relationship between the setting time of the impression material and the water temperature used was observed. With 19.5☌ water the mean setting time was reduced to 3.78☐.13 minutes. Results: Mixing the impression material with 7☌ water resulted in a mean setting time of 5.56☐.46 minutes. For each water temperature investigated three trials were conducted and the mean setting time was calculated. A marble was continuously placed on and removed from the surface of the alginate material until no visible depression was evident at which point the mixture was considered set. A timer was started upon addition of the water to the powder and the mixture was spatulated until homogenous in consistency. Methods: The impression material was spatulated with temperatures of water at approximately 7☌, 19.5☌ and 45☌. Objective: The purpose of this experiment was to qualitatively examine the influence that water temperature has on the setting time of Jeltrate Alginate Regular Set using a simple experimental design and basic materials. ![]() In order to achieve an optimal impression the setting time of alginate is easily manipulated to permit more or less working time by modifying the temperature of water used in preparation.
