Objective: Evaluate the effect of thermal aging and chemical disinfection on microhardness and flexural strength of resins. Materials and methods: Two flexible resins - Deflex® ClassicSR and Deflex®SupraSF and one thermo-polymerizable resin - ProBase® Hot were subjected to 1000 cycles of thermal aging (n=32) and three types of chemical disinfection (n=8): Corega®Whitening, Corega®Oxygen-Bio-Active, 2,5% Sodium Hypochlorite and control (distilled water). The Knoop microhardness and flexural strength at 3 points were evaluated. We used Mann-Whitney and T-tes (α = 0.05). Results: Thermal aging only influenced the microhardness of ClassicSR and SupraSF (p AID - 857831
