Dimensional Change

• • The MTA-Fillapex is paste/paste material presented in automix double syringes or tubes which provide an
    adequate consistency for the cement insertion in the root canal. The presence of nanoparticles enables a
    homogeneous mixture and better flow of the product.
  • MTA-Fillapex shows an optimized flow due to the nanoparticles. It provides excellent filling and sealing of the
    canals, main and lateral, as shown below.
  • The two pastes of MTA-Fillapex were measured in equal volumes and dispensed in a glass plate.
  • After complete homogenization (±30 s), a volume of 0.05 ml of the mixture was dispensed on the center of a glass plate. At 180±5 s after mixing, a second plate was placed centrally on the top of the sealer, with a 100 g weight on it (total mass on the plate of 120±2 g).
     
  • Ten minutes after mixing the weight was removed and the maximum and minimum diameters of the
    compressed disc of MTA-Fillapex were measured.
  • Initially, we measured the thickness of two glass plates together, using a Mitutoyo Digital micrometer
     
  • Then, a portion of the MTA-Fillapex previously handled was dispensed in the center of one of the
    glass plates, covering it with another glass plate
     
  • Finally, a weight of 150 N (15 Kg) was applied on the center of the plate
     
  • The sealant filled completely the space between the glass plates
     
  • After 10 minutes, the thickness of the two glass plates plus the sealing thickness were measured with the aid of a Mitutoyo Digital micrometer.
     
  • The MTA-Fillapex, unlike resin cement, presents an important characteristic required by the sealing materials, which is the setting expansion.
  • 2g of MTA-Fillapex were prepared with 0.02 ml of water and dispensed into a mold to obtain three samples
  • Two glass plates were pressed upon both surfaces of the mold containing the material. The glass plates were fixed with the aid of a device for stabilization
  • After 5 minutes, the mold was taken to a relative humidity chamber of 95 % to 100% and later placed in dry heat at 37°C to reach the setting time (2h 20min);
  • The setting was confirmed by surface indentation with a Gilmore needle until the sample did not present any visible marks
  • The samples were polished with 600 grit sandpaper
  • The samples were measured
  • These samples were placed in distilled water and in dry heat at 37°C
