%X elastomerics materials currently represent a major choice in the dental market as an impression material. the aim of this study was to asses shore a hardness of two condensation silicones (zetaplus - zhermack and clonage - dfl) using two impression techniques (putty and putty/wash) under influence of chemical disinfection with clorhexidine spray to 2% (for five minutes). fifty-six specimens were made in metallic matrices, subdivided in 4 groups for each impression technique; half of each technique was submitted to chemical disinfection. hardness test was performed with a durometer (gsd 709) according astm specifications (d-2240), the results were submitted to analyses of variance (anova) and tukeyˋs test (p<0.05). it was concluded that for all experimental condition, difference statistically significant was found.
