conclusions: The restoration of root canal treated teeth – because of the significant loss of tooth structureis often achieved with post and core. However, posts may generate stresses, which lead to vertical root fracture and the loss of the tooth. Since post design, materials used and post space preparation has significant influence on vertical fracture prevalence, broad investigation is in pr...

Presented here is the second set of testing conducted by the Technology Validation Laboratory for Photonics at NASA Goddard Space Flight Center on the twelve optical fiber ribbon cable with MTP array connector for space flight environments. In the first set of testing the commercial 62.5/125 cable assembly was characterized using space flight parameters (published in SPIE Vol. 3440 ).[1] The te...

The commodity created under global capitalism originates from everywhere and seems to have been made by everyone. Endlessly fungible, it is also endlessly divisible. Analysis of the commodity reveals the indissoluble link between commodification and technologization. Although the medieval commodity is a very different kind of object, not issuing from an economy dedicated to commodity production...

Post-root canal adaptation represents an important role in the biomechanical performance of teeth and the post-core systems. Close canal adaptation with minimal tooth structure removal provides a conservative and long-lasting treatment for the restoration of endodontically treated teeth. In some cases the root configuration could anatomically be an oval form rather than a circular shape or the ...
