AB  - PURPOSE: To assess the impact of thermal cycling on flexural properties of 
      denture base acrylic resin reinforced with microcrystalline cellulose (MCC) 
      derived from oil palm empty fruit bunch (OPEFB). MATERIALS AND METHODS: The 
      flexural strength and flexural modulus, following thermal cycling (5000 cycles of 
      5-55 degrees C) of 3 MCC-reinforced poly methyl methacrylate (PMMA) specimens were 
      compared with the conventional and commercially available high-impact PMMA. The 3 
      test groups were represented by addition of various weight combinations of MCC 
      and acrylic powders. RESULTS: All 3 test groups with the addition of MCC 
      demonstrated improved flexural strength and flexural modulus compared to the 
      conventional resin, without and after thermal cycling. The highest mean flexural 
      strength corresponded to the specimens reinforced with 5% MCC followed by 2% MCC. 
      CONCLUSION: Addition of MCC derived from OPEFB to PMMA may be a viable 
      alternative to the existing, commercially available synthetic reinforced PMMA 
      resins. The potential application of natural fillers in the fabrication of a 
      reinforced denture base resin needs further study.
