Thermomechanical compaction of gutta-percha: a scanning electron microscope study.
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.
