Effectiveness of different formulations of Endo-PTC to promote root canal cleaning.

Context: Endo-PTC are used during endodontic treatment; however, until now no study evaluated the cleaning of dentin walls after use of different Endo-PTC formulations.

Aims: The aim of this study was to assess qualitatively, by means of scanning electron microscopy (SEM) images, the cleaning of dentin walls of root canals after chemomechanical preparation (CMP) using Endo-PTC cream and Endo-PTC light associated to 2.5% sodium hypochlorite and 17% ethylenediamine tetraacetate (EDTA).
