Permanent magnetism in apoferritin-encapsulated Pd nanoparticles

2007

Pd nanoparticles have been prepared within the apoferritin cavity. X-Ray powder diffraction, transmission electronic microscopy and magnetization measurements have been used for characterizing the nanoparticles. The nanoparticles exhibit permanent magnetism at room temperature.

Evaluation of the apical sealing ability and adaptation to the dentin of two resin-based Sealers: An in vitro study

2013

Aim: To quantitatively evaluate the apical sealing ability and adaptation of two resin-based sealers to dentin. Materials and Methods: Fifty freshly extracted mandibular first premolars were taken and sectioned at the cemento-enamel junction. Thirty teeth were subjected to a leakage study by the resin infiltration method with two groups of 10 teeth each. Group I teeth were obturated with methacrylate resin-based sealer (EnoRez) and Group II teeth were obturated with epoxy resin-based sealer (AH Plus). The remaining 10 teeth were used as controls (positive and negative of five teeth each). Twenty teeth were divided into two groups and obturated as in the leakage study and subjected to a scan…
