There is current concern in the UK over the possible transmission of prions via contaminated surgical instruments. Some dental instruments (endodontic files) raise particular concerns by virtue of their intimate contact with terminal branches of the trigeminal nerve. A visual assessment using a dissecting light microscope and scanning electron microscopy of endodontic files after clinical use a...

Resumo: Este estudo utiliza um modelo de inteligência artificial, uma rede neural com base radial (RBF), para dar suporte a diagnósticos radiográficos de cáries dentárias. Cento e sessenta imagens radiografias de faces proximais de dentes humanos extraídos foram avaliadas no que se refere à presença ou ausência de cárie por vinte e cinco examinadores. As condições reais de cada dente, denominad...
