The cares at the manipulation of the alginate (condensation, disinfection of the impression and the time elapsed until the leak of the plaster) deserve special attention considering the great amount of distortions occurring every time the impression is not fill of plaster in a brief space of time and appropriate storage conditions. Besides its adaptation to the plaster suffers influence of the events happened after the impression is removed of the mouth. The purpose of this research was to evaluate the wetting capacity of three brands of alginate (Jeltrate™,Hydrogum™ e Orthoprint™) by the plaster type III (Rio™) under the influence of disinfection by sodium hypochlorite 1% sprays and the time of storage of 15 minutes,30 minutes, 1 hour, 6, 12 and 24 hours. There were made 60 impressions of each brand of alginate divided in two groups (water and sodium hypochlorite 1%) rearranged after the application of the sodium hypochlorite spray according to the storage time (15 or 30 minutes and 1,6,12, or 24 hours). On the surface of the impressions 2ml of plaster were flowed, proportioned and condensed in agreement with manufacturer‘s instructions. After the final setting expansion the casts were sectioned vertically and medially, regularized at the cut surface (emery paper 400) and setted for reading the contact angle at the microscope Carl Zeiss. The obtained results, submitted to statistical treatment (ANOVA) revealed significant differences when compared the employed solutions (water and sodium hypochlorite 1%) and the time of storage. The sodium hypochlorite 1% exhibited the smallest contact angles and the times of storage of 15 minutes and 6 hours the smallest and larger angles, respectively. It can be concluded that the alginate impressions exhibited larger adaptation to the plaster when disinfected by hypochlorite of sodium 1% and stocked by 15 minutes.
