OBJECTIVE The aim of this study was to evaluate the marginal adaptation of Biodentine in comparison with Mineral Trioxide Aggregate (MTA) and Intermediate Restorative Material (IRM), as a root end filling material, using Scanning Electron Microscopy (SEM). MATERIALS AND METHODS Thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. Three millimetres of the...
Polymethyl methacrylate (PMMA), commonly known as bone cement, is widely used in orthopaedic surgery, mainly for prosthesis fixation, stabilizing compressive vertebral fracture or filling defects. Bone cement a potentially new repair material that has been investigated recently dentistry because of its properties like low cytotoxicity, excellent biocompatibility and resistance to moist environm...
Inadequate apical seal is the major cause of surgical endodontic failure. The root-end filling material used should prevent egress of potential contaminants into periapical tissue. The purpose of this study was to compare the sealing ability of four root-end filling materials: white mineral trioxide aggregate (MTA), gray MTA, white Portland cement (PC) and gray PC by dye leakage test. Ninety-si...
The Precambrian Takab complex consists of various metamorphic rocks including metabasites, metaultramafic rocks, calc-silicates and marbles which are metamorphosed under green schist to granulite facies. The pick metamorphic rocks are retrogressively metamorphosed during crustal exhumation related to pressure and temperature decreasing as well as H2O-rich fluid infiltrations. Retrograde metamor...
Abstract Background Oral hygiene is the individual approach to mechanical actions performed properly with right elements at predetermined time intervals. This information reflected in an almost illogical and very understandable way children aged 3–6 years, who conceive whole procedure as something advised by parent. In teenage patients, this considered be learned now turned into a routine of hy...
High Q frequency reference devices are essential components in many Integrated circuits. This paper will focus on the Resonant Suspended Gate (RSG) MOSFET. The gate in this structure has been designed to resonate at 38.4MHz. The MOSFET in this device has a retrograde channel to achieve high output current. For this purpose, abrupt retrograde channel and Gaussian retrograde channels have bee...
Abstract Background Primary urethral cancer in males is rare. Clear cell adenocarcinoma more We report a case an African male suspected to have stricture. Case presentation A 66-year-old man presented with preceding intermittent haematuria and acute urinary retention. Failed attempts at catheterisation necessitating suprapubic catheter insertion raised the suspicion of Multiple irregular fillin...
