This study aimed to compare the dimensional sta¬bility of polyether (P), addition silicone auto mixed (ASP) and addition silicone hand mixed (ASM) molds after disinfection with sodium hypochlorite 1% (HP), peracetic acid 0,2% (AP), and no disinfection. Mensurations cross posterior arch (CAP), cross-anterior arch (CAA), and antero-posterior on right (APD) and left sides (APE). Statistical analysis (Kruskall-Wallis) showed significant difference only in measure CAP: 1) between P (0,1203% ± 0,0442) and SAP (0,0350% ± 0,0158) disinfected with HP; 2) between P (0,1345% ± 0,1059) and SAP (0,0264% ± 0,0302) disinfected with AP; and 3) between SAM (0,1054% ± 0,0419) and SAP (0,0264% ± 0,0302). Disinfection with peracetic acid and sodium hypochlorite did not interfere negatively in the dimensional accuracy of the impressions tested in this study.
