The purpose of this study was to assess the residual resin-based sealers in root canals after post space preparation by confocal laser scanning microscopy. The way to observe the residual resin-based sealers using two fluorescent dyes has established. Four different resin-based sealers were examined by using this method, and all sealers were remained in dentinal tubules in the root canals. The residual resin-based sealers in the root canals could not be entirely removed after using ultrasonic tips preparation.
