Adaptation of injected thermoplasticized gutta-percha in the absence of the dentinal smear layer.
The adaptation of thermoplasticized, injected gutta-percha to prepared dentine devoid of smear layer was examined with SEM. Findings indicate a penetration of gutta-percha into the patient dentinal tubules with or without root canal sealer. The clinical implications of these findings are discussed.
