All of the metal in my teeth has been replaced with composites or capped. This shifts the resonance out of the AM band into the marine band where there are fewer, less powerful transmitters nearby. YMMV 73's Richard Clark, KB7QHC Richard, you gotta pay closer attention to what the doc is doing inside your mouth! Caps have a ceramic layer atop a metal (titanium?) mandrel. And even more fun is that there's a rather large and long stainless steel post that was drilled down to nearly the end of the root of that tooth. After the post is cemented into the base of the tooth, the cap is cemented onto the post. The post might be 5/8" long, and the cap sits on the post separated by a dielectric adhesive. Although the nerve was "killed" at the point it enters the root of the tooth, the rest of the nerve bundle really isn't that far from the end of the stainless steel post. Sounds like an interesting collection of resonant structures, lossy dielectrics, conductive fluids and potential diodes; all located quite near to your nervous system. Any of our EZNEC gurus care to model that structure? Ed wb6wsn |
