A proper bond between root canal filling materials and dentin surface is essential to resist dislodgement guarantee long-term success. Blood exposure likely occur in various clinical situations which calcium silicate-based are used; therefore, it fundamental render data concerning the influence of blood on strength. The present study aims evaluate effect contamination push-out strength obtained...

introduction : solubility of root filling materials is heavily influenced by the environment they are in contact with. this study compared the solubility of proroot mta in deionized water and synthetic tissue fluid. materials & methods: forty specimens of prepared mta were immersed in deionized water and synthetic tissue fluid (20 samples each). the solubility was assessed after 7 and 28 days. ...

Abstract Objective To compare the push out bond strength of MTA apical plug in a simulated immature root, after using different irrigation protocols; NaOCl + 20% Etidronic acid (HEBP) and 17% Ethylenediaminetetraacetic (EDTA) with without diode laser activation. Methods Twenty-eight extracted single straight rooted permanent human teeth were selected. The root lengths standardized (15 mm) by de...

Abstract:
 Aim: to evaluate the bone healing in failed endodontically treated teeth after surgical removal of periapical lesions and placement hydroxyapatite (HA), nanohydroxyapatite (nHA) a combination with platelet rich fibrin (PRF) periapically. Subjects methods: study was conducted on twenty-four patients having radiolucency single rooted teeth. The selected were divided into three gro...

Introduction: Cervical root resorption is one of the most important complications of intra coronal bleaching. A way of preventing this type of resorption is using a coronal barrier under the bleaching materials. The aim of this study was to compare the sealing ability of glass ionomer cement and Pro Root Mineral Trioxide Aggregate (MTA) as a coronal barrier in intra coronal bleaching. Materi...

introduction: this in vitro study compared the cytotoxic effects of three commercially available mta formulations naming proroot mta (pmta), angelus mta (amta), and root mta (rmta), with calcium-enriched mixture (cem) cement and a new nanohybrid mta (nmta) on human dental pulp stem cells (dpsc). methods and materials: four disc-shaped specimens of each material were prepared. after completion o...
