Objectives: The objective of this study was to evaluate the continuous wave condensation (CWC) technique for sealer adaptation to the root canal wall, sealer adaptation to the gutta-percha, and presence of voids.

Methods: Ten mandibular molars with fully developed roots containing two mesial canals were instrumented using rotary and hand files. Ten teeth were obturated using the CWC technique. Obturated teeth were placed in incubation for seven days to allow the sealer to completely set. The mesial buccal root was separated, placed into acrylic blocks and then sectioned into coronal, middle, and apical portions. Digital images of the apical and middle portions were taken using the Nikon SMZ800 stereomicroscope. The ratio of voids to total area of filled canals was evaluated for each digital image using NIS Elements AR Program.

Results: When obturating the mesial canals of lower mandibular first molars, the CWC technique will produce 5.82263% of voids relative to the total area of filled canal space.

Conclusions: The purpose of this study was to determine the effectiveness of the CWC technique in obturating the mesial root of mandibular first molars. As a result, it will encourage the use of the CWC technique when obturating mesial canals of mandibular first molars.
