Abstract

Objective: The aim of this study was to evaluate the percentage of sealer penetration in root canals filled with the Thermafil or RealSeal-1 systems analyzed by confocal laser scanning microscopy (CLSM). Study design: Twenty canals in 10 mesial roots of mandibular molars were cleaned and shaped using ProTaper and ProFile instruments to a size 35 and .04 taper at the apex and filled using RealSeal-1 or Thermafil systems in the mesial canal of each root. Horizontal sections were made at the 3 and 5 mm levels from the apex, and the percentage of sealer penetration in the root canal walls was analyzed using CLSM. Results: Thin layers of sealer (2-30 μm) and sealer tags into dentinal tubules were found in the root canal walls in a high percentage using both techniques at both evaluated levels, with no statistical differences between the techniques (Student t test: P > .05). Conclusion: The percentage of sealer penetration in the root canal walls was similar using both thermoplastic carriers based systems.
