Root Canal Obturation by Electrochemical Precipitation of Calcium Phosphates

Achieving adequate disinfection and preventing reinfection is the major goal in endodontic treatment. Variation canal morphology open porosity of dentine prevents achieving complete disinfection. Questionable biocompatibility materials as well a lack sealing ability questions usefulness current obturation methods. With novel approach based on use boron-doped diamond (BDD) electrodes having shown promising results it was this series experiments to investigate possibility BDD-mediated situ forming biocompatible material. A combination calcium phosphate maleic acid used precursor solution while Ion Chromatography Mass Spectrometry (IC-MS), Raman spectroscopy (RAMAN), X-ray diffraction (XRD), energy dispersive (EDX), scanning electron microscopy (SEM), dye penetration micro-computed tomography (µCT) were applied for characterizing precipitate. It possible achieve precipitation brushite clinically applicable timeframe. However, tight system could not be achieved.
