title: In vitro evaluation of apical microleakage of a new MTA-based sealer.
abstract: OBJECTIVE
  To evaluate the apical microleakage of a new MTAbased sealer; MTA Fillapex (Angelus) and compare it with ProRoot MTA (Dentsply) and AH Plus (Dentsply).
  
  
  METHODS
  51 single-rooted permanent teeth were selected and the roots were prepared using a rotary system. The samples were divided randomly into 3 groups (n=15). Six roots were used as positive and negative controls. The teeth were obturated with respectively; A. AH Plus and gutta percha (DiaDent); B. MTA Fillapex and gutta percha; C. ProRoot MTA. Specimens were placed in 2% methylene blue dye for 72h. Then linear dye penetration was measured. Measurements were analysed statistically.
  
  
  RESULTS
  MTA Fillapex group had significantly higher microleakage values (p<0.05). There were no statistically significant differences between MTA and AH Plus groups (p>0.05).
  
  
  CONCLUSIONS
  The sealing ability of AH Plus and MTA were similar whilst MTA Fillapex showed more microleakage than the other two materials.
