The nature and distribution of corrosion products in teeth restored with metal crowns retained by stainless steel posts were examined by means of energy-dispersive X-ray microanalysis, microradiography, and electron microscopy. The corrosion products consisted of calcium, phosphorous, iron, chromium, nickel, zinc, stannum and other elements. A possible root fracturing mechanism is discussed.
通过能量色散X射线微分析、显微放射摄影和电子显微镜检查了用不锈钢桩保留的金属冠修复牙齿中腐蚀产物的性质和分布。腐蚀产物由钙、磷、铁、铬、镍、锌、锡和其他元素组成。讨论了一种可能的牙根断裂机制。
