OBJECTIVE To investigate regional root canal push-out bond strengths for two fiber-reinforced post types using two adhesive systems. METHODS The crowns of 24 recently extracted sound maxillary central incisors were sectioned transversely 2 mm coronal to the labial cemento-enamel junction, and the roots treated endodontically. Following standardized post(More)
Arginine-glycine-aspartic acid (RGD) ligand is often chemically attached to polycation vector to improve the transfection efficiency. However, the chemical reaction may reduce or even inactivate the biological activities of peptides. In order to retain the targeting ability and biological activities, the RGD peptide was noncovalently introduced into(More)
PURPOSE To evaluate the effect of ferrule preparation length on the fracture resistance after simulated surgical crown lengthening and after forced tooth eruption of endodontically-treated teeth restored with a carbon fiber-reinforced post-and-core system. METHODS 40 extracted endodontically-treated mandibular first premolars were decoronated 1.0 mm(More)
We sought to evaluate the effect of 125I radioactive seed implantation combined with prosthesis denture on the treatment of oral and maxillofacial malignancy. For this purpose, 10 patients with glandule palatine malignancy were selected and subjected to the treatment plan of radioactive seed implantation during CT examination. All patients were treated as(More)
This study investigated the effect of a crown-lengthening ferrule on the fracture resistance of endodontically-treated teeth restored with two dowel-core systems. Thirty-two extracted mandibular first premolars were sectioned perpendicular to the long axis at a point 1.0 mm occlusal to the buccal cementoenamel junction. Following endodontic treatment, the(More)
The present study aimed to evaluate efficacy and adverse effects of Nimotuzumab combined with docetaxel–cisplatin–fluorouracil regimen in the treatment of advanced oral carcinoma. Nine patients with advanced oral carcinoma were treated with Nimotuzumab combined with docetaxel–cisplatin–fluorouracil regimen (test group). The treatment was given as follows:(More)
