PURPOSE Clinicians commonly encounter cases in which it is difficult to determine whether adjacent radiopacities are normal or pathologic. The ideal radiopacity of composite resin is equal to or higher than that of the same thickness of aluminum. We aimed to investigate the possible effects of different curing times on the post-24-hour radiopacity of composite resins on digital radiographs. M...

introduction: the aim of this in vitro study was to evaluate the setting time, flow, film thickness, solubility, radiopacity and characterization analysis of three epoxy resin based sealers including two experimental sealers and ah-26. methods and materials: five samples of each material were evaluated for setting time, flow, film thickness, solubility and radiopacity according to iso 6876 stan...

BACKGROUND Barium sulfate powder used for radiopacity of experimental blood clots (EBCs) for testing mechanical thrombectomy devices (MTD) has negative effects on EBCs mechanical properties. In vitro and in vivo exploration was performed to determine if the iodine based contrast medium will have less negative effects on the EBCs than barium. MATERIALS AND METHODS Fresh blood from 2 swine was ...

OBJECTIVE RetroMTA® is a new hydraulic bioceramic indicated for pulp capping, perforations or root resorption repair, apexification and apical surgery. The aim of this study was to compare the radiopacity, pH variation and cytotoxicity of this material to ProRoot® MTA. MATERIAL AND METHODS Mixed cements were exposed to a digital x-ray along with an aluminum stepwedge for the radiopacity assay...

This study evaluated the radiopacity of different resin-based luting materials and compared the results to human and bovine dental hard tissues. Disc specimens (N=130, n=10 per group) (diameter: 6 mm, thickness: 1 mm) were prepared from 10 resin-based and 3 conventional luting cements. Human canine dentin (n=10), bovine enamel (n=10), bovine dentin (n=10) and Aluminium (Al) step wedge were used...

OBJECTIVE The aim of the present study was to evaluate the radiopacity of Portland and MTA-based cements using the Digora TM digital radiographic system. MATERIAL AND METHODS The performed tests followed specification number 57 from the American National Standard Institute/American Dental Association (2000) for endodontic sealing materials. The materials were placed in 5 acrylic plates, espec...

OBJECTIVE The present study evaluated the subcutaneous connective tissue reactions and the radiopacity of MTA, Portland cement (PC), and Portland cement plus bismuth oxide (BO). STUDY DESIGN Forty rats were divided into 5 groups (n = 8 per group): A1: Control (empty capsule); A2: Pro-Root MTA; A3: PC; A4: PC + BO 1:1; and A5: PC + BO 2:1. Polyethylene tubes were filled with the test materials...

AIM To evaluate radiopacity of root filling materials using digital radiography. METHODOLOGY The sealers tested were AH Plus, Endofill, EndoREZ and Epiphany. Gutta-percha (Dentsply Maillefer) and Resilon cones were also tested. Acrylic plates, containing six wells, measuring 1 mm in depth and 5 mm in diameter, were prepared for the test, and filled with the materials. The test samples were ra...

The results of a comparative analysis dental glass ionomer cements are compared: "AHfil +" (AHL, United Kingdom), "Ketac Molar Easymix" (3M ESPE, USA), "Fuji IX GP" (GC, Japan), "ProGlass Nine" (Silmet , Israel), "Polyacrylin" (TechnoDent, Russia), "Cemion" (VladMiVa, "Kemfil" (StomaDent, Russia) and "Glassin Rest" (Omega-Dent, in terms working time, hardening strength compression, radiopacity,...
