To have success in endodontic treatment it is necessary that the sealing airtight as possible of the root canal system, with suitable material such as gutta-percha and sealer. There are sealers of different compositions, which should allow the sealing of the root canal system, preventing recontamination place and favoring the success of endodontic therapy. In this study were evaluated the  apical  microleakage  after  obturation  using  different  root  canal  sealers  widely  employed  in  the   market,  with  different  compositions.  For  this  study,  85  single  rooted  teeth  premolars  which  have   removed  their  crowns  and  root  canals  prepared  and  filled  using  four  types  of  cement:  AH  Plus,   Endofill,  Acroseal  and  Real  Seal  SE.  All  samples  were  sealed  and  submitted  to  microleakage  with   Indian   ink;;   longitudinal   cuts   made   on   both   sides   of   the   tooth   and   cleaved;;   apical   images   were   obtained.  The  areas  of  dye  penetration  were  measured  on  a  computer  using  specific  software  and subjected to statistical analysis. It was concluded that the Acroseal ® showed the highest mean microleakage  with  no  statistically  significant  difference  in  relation  to  the  RealSeal  SE®,  but  with   significant  differences  compared  to  Endofill  ®  and  AHPlus  ®.
