Evaluation of Selective Physicochemical and Biological Properties of Different Root Canal Sealers.

Introduction: This study aimed to evaluate the chemical composition, water solubility, radiopacity, pH, electrical conductivity and cytotoxicity of four different root canal sealers.

Methods And Materials: Four materials were tested including an epoxy resin-based sealer (AH-Plus), a calcium silicate-based sealer (MTA Fillapex), a calcium hydroxide-based sealer (Sealapex) and a zinc-oxide-eugenol-based sealer (Endofill). The materials were submitted to energy-dispersive x-ray microanalysis for elemental chemical composition.

Antimicrobial Potential of Laser Diode in Infected Dentin.

Aim: To evaluate the antibacterial effect of diode laser, associated or not with 2.5% sodium hypochlorite (NaOCl), against Enterococcus faecalis.

Materials And Methods: Eighty dentin blocks were obtained from single-rooted human teeth and sterilized.
