TI  - Penetrability of AH plus and MTA fillapex after endodontic treatment and 
      retreatment: a confocal laser scanning microscopy study.

AB  - The aim of the study was to assess the penetrability of two endodontic sealers 
      (AH Plus and MTA Fillapex) into dentinal tubules, submitted to endodontic 
      treatment and subsequently to endodontic retreatment. Thirty ex vivo incisors 
      were prepared using ProTaper rotary system up to F3 instrument and divided in 
      three groups according to the endodontic sealer used for root canal filling: AH 
      Plus (AHP), MTA Fillapex (MTAF), and control group (CG) without using EDTA 
      previously to the root canal filling. Rhodamine B dye (red) was incorporated to 
      the sealers in order to provide the fluorescence which will enable confocal laser 
      scanning microscopy (CLSM) assessment. All specimens were filled with 
      gutta-percha cones using the lateral compaction technique. The specimens were 
      submitted to endodontic retreatment using ProTaper Retreatment system, 
      re-prepared up to F5 instruments and filled with gutta-percha cones and the same 
      sealer used during endodontic retreatment. Fluorescein dye (green) was 
      incorporated to the sealer in order to distinguish from the first filling. The 
      roots were sectioned 2 mm from the apex and assessed by CLSM. No difference was 
      found between the two experimental groups (P > 0.05). On the other hand, in the 
      control group the sealers were not capable to penetrate into dentinal tubules 
      after endodontic treatment (P > 0.05). In retreatment cases, none of the sealers 
      were able to penetrate into dentin tubules. It can be concluded that sealer 
      penetrability is high during endodontic treatment. However, MTA Fillapex and AH 
      Plus do not penetrate into dentinal tubules after endodontic retreatment.
