AB  - STATEMENT OF PROBLEM: While glass ionomer cements have many unique properties and 
      advantages, they still lack favorable mechanical properties. EQUIA Forte Fil is a 
      newly developed glass ionomer cement (GIC) with improved mechanical strength. 
      However, research and data on the physical properties of EQUIA Forte Fil are 
      lacking. PURPOSE: The purpose of this in vitro study was to evaluate and compare 
      the compressive, diametral tensile, and flexural strengths of EQUIA Forte Fil 
      with Fuji IX GP and ChemFil Rock, restorative GICs commonly used in dentistry. 
      Moreover, fluoride-releasing properties and surface hardness of the GICs were 
      also assessed. MATERIAL AND METHODS: Ten disk-shaped specimens of each GIC (EQUIA 
      Forte Fil, Fuji IX GP, and ChemFil Rock) were fabricated for mechanical and 
      surface hardness tests by using polydimethylsiloxane (PDMS) molds. The specimens 
      were tested after 24 hours and 7 days of immersion in distilled water at 37  degrees C. 
      By using a mechanical testing machine, the compressive, diametral tensile, and 
      flexural strengths of each GIC were measured. Fluoride-releasing properties were 
      also evaluated (10 specimens per group). A microhardness tester was used to 
      measure the surface hardness. The mean data were analyzed by using 1- and 2-way 
      ANOVA (alpha=.05). RESULTS: EQUIA Forte Fil glass ionomer cements exhibited 
      significantly greater (P<.05) flexural strength and surface hardness than Fuji IX 
      GIC specimens. However, no significant difference (P>.05) was observed between 
      the compressive and diametral tensile strength of EQUIA Forte Fil and Fuji IX GIC 
      specimens. ChemFil Rock exhibited higher flexural strength than EQUIA Forte Fil 
      (P>.05) but significantly lower compressive strength and microhardness (P<.05). 
      Tested GICs matured after 1 week of immersion in distilled water, demonstrating a 
      significant improvement in their mechanical properties. All the examined glass 
      ionomers exhibited comparable initial fluoride-releasing properties, whereas 
      EQUIA Forte Fil exhibited significantly higher (P<.05) amounts of fluoride 
      release from the bulk of the material after 4 weeks. CONCLUSIONS: EQUIA Forte Fil 
      is a promising restorative material with superior flexural strength and surface 
      hardness compared with its predecessor, Fuji IX GP, or other commercially 
      available glass ionomers.
