Failure to grasp the rationale behind cleaning and shaping concepts can increase the occurrence of needless complications, such as ledges. A ledge is created when the working length can no longer be negotiated and the original pathway of the canal has been lost. Extension of the access cavity to provide unobstructed access to the root canals, precurving and not forcing instruments, using NiTi f...

The effectiveness of fisheries management is limited by the paucity of information on how management tools, such as marine protected areas, impact key fisheries species. In the Gulf of Maine, more information is needed to determine how marine protected areas such as the Cashes Ledge Closure Area influence fish population dynamics and subsequently the status of fishery stocks. We utilized video ...

This work reports experimental data comparing the low frequency noise spectrum of InP based HBTs. Double heterojunction device structures are examined with and without surface passivation ledges. INTRODUCTION Compound semiconductor InP heterojunction bipolar transistors (HBTs) hold great promise for ultra high-speed analog microwave circuit applications. The low frequency noise characteristics ...

Radix entomolaris is a supernumerary root located distolingually on permanent mandibular molars. It considered as an anatomical variant and usually curved buccolingually. The presence of radix can be endodontically challenging to treat susceptible endodontic mishaps such ledge. This report describes the management ledge in with type-3 curvature tooth 46. Ledge was bypassed using pre-curved K-fi...

Aim: To compare the effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved root canals. Methods: Eighty acrylic-resin blocks with curved canals were instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 was used for trying to surpass the deviation, and the blocks that permitted surpassing were rejected. The remainin...
