Corrosion of silver cones in the subcutaneous connective tissue of the rat: A preliminary scanning electron microscope, electron microprobe, and histological study

Abstract

Size 140 silver cones and solid Teflon rods of the same size were implanted in the subcutaneous connective tissue of the rat in an effort to analyze the tissue response to silver cones and their possible Corrosion products at different observation periods. corrosion phenomena and the presence of corrosive by-products on the silver cone surfaces and in the tissues surrounding the implants were studied using the scanning electron microscope and the electron microprobe. Our results showed that despite the silver cones rapidly corroding in the subcutaneous connective tissue of the rat, they appeared to be well tolerated by the tissues. When granulomatous tissues persisted in long observation periods, they seemed to be produced by the presence of corrosive by-products which were released from the cones. However, we feel that more extensive experiences will be necessary to study the possible correlation between the corrosion of the silver cone and the tissue response to silver corrosion products.

El objetivo de este estudio es observar si existe alguna correlación entre la resquesta de los tejidos y la presencia de corrosión sobre las superficies de los conos de plata previamente implantados en el tejido conectivo subcutáneo de la rata.
