AB  - PURPOSE: The aim of this study was to compare the differences between the ASTM 
      D790 and ISO 20795.1.2013 standards in evaluating the flexural strength of heat 
      cure poly methyl methacrylate (PMMA) denture base resin. MATERIALS AND METHODS: 
      30 heat cure denture base samples were fabricated in accordance to ISO 
      20795.1.2013 and ASTM D790 Standards. The specimens were finished and stored 
      following the standardized protocol. The flexural strength was determined using 
      universal testing machine at cross head speed of 1.50 mm/min and a span length of 
      40.00 mm. The mean flexural strength values were calculated in megapascals (MPa), 
      and statistically analyzed. RESULTS: The mean flexural strength of heat cure PMMA 
      found with ISO and ASTM ranged between 60.492 MPa and 61.470 MPa. There was no 
      significant difference between the two methods. CONCLUSION: The quantitative 
      differences existed in the flexural strength of denture base resin between ISO 
      20795.1.2013 and ASTM 790 protocols but those differences had no statistical and 
      clinical significance.
