BACKGROUND The aim of this study was to investigate the physical properties and biological effects of an experimentally developed injectable premixed calcium-silicate root canal sealer (Endoseal) in comparison with mineral trioxide aggregate (MTA) and a resin-based sealer (AHplus). METHODS The pH, solubility, dimensional change, flow, and radiopacity of the materials were evaluated. Biocompat...
The application of biomaterials used in regenerative endodontics should be traceable. In this study, we checked some basic effects of rendering a fibrin hydrogel radiopaque using an iodine-based contrast agent (iodixanol) approved for systemic application. Fibrin hydrogels were prepared from a fibrin sealant (Tisseel) using either an isotonic iodixanol solution (Visipaque 320, test) or Tris buf...
The surface gloss, radiopacity and enamel/dentin shear bond strengths (SBS)s of five commercially available contemporary universal composite resins (CR)s were examined. tested CRs as follows: G-aenial A’CHORD (GA), Charisma Diamond (CD), Neo SpectraTMST(NS), Filtek(F) Estelite Asteria(EA). Twelve cylindrical specimens per group fabricated gloss measurements performed using a meter after polishi...
The controlled precipitation of strontium fluoroapatite crystals was studied in four base glass compositions derived from the SiO2-Al2O3-Y2O3-SrO-Na2O-K2O/Rb2O/Cs2O-P2O5-F system. The crystal phase formation of these glasses and the main properties of the glass-ceramics, such as thermal and optical properties and radiopacity were compared with a fifth, a reference glass-ceramic. The reference g...
Uhlhorn, H. 2000. Third carpal bone sclerosis Radiographic evaluation and clinical implications in Standardbred trotters. Doctoral dissertation. The aims of this thesis were to evaluate the DPr-DDiO projection for the assessment of sclerosis and to study the relationships between altered third carpal bone (C3) radiopacity and previous exercise, previous carpal lameness, clinical appearance, and...
