The common technique to hermetically fill prepared root canals involves the use of "standardised" gutta-percha cones that are selected to fit the apical portion of the prepared canal space. These gutta-percha cones are manufactured to conform to a standard size and taper which should correspond to the size and taper of standard root canal instruments.(More)
This paper presents a reconfigurable slot antenna that uses a close-coupled biasing technique to facilitate the switching between two frequency bands. The technique uses a very thin double layered flexible copper clad Mylar substrate with the slot antenna on the front side and the biasing circuits at the backside of the design. The biasing circuit uses a(More)
