The root canals of 20 freshly extracted maxillary central incisors and canines were prepared and filled by thermo‐mechanical or lateral condensation of gutta‐percha cones without sealer. The adaptation of the filling material to the root canal walls was then examined with a scanning electron microscope. A more homogenized mass of gutta‐percha could be detected in teeth filled by thermomechanical compaction of gutta‐percha cones. The morphology of the prepared root canal system was well reproduced by the use of both techniques.
