ABSTRACT:
A degradation resistant gingival retraction cord including silk is formed from two or more strands that are braided, twisted or woven. The degradation resistant retraction cord comprises at least about 50% silk, 80% silk, 90% silk, 95% silk, or essentially all silk. They are able to maintain at least about 70%, 80% or 90% of this tensile strength for a time period of at least about 7 days, 30 days, 60 days, or 90 days. The silk retraction cords have the look, feel and desirable utility of a thin, flexible, and resilient natural fiber cord, while also resisting degradation when pre-impregnated with a corrosive agent. Such cords combine the degradation resistance of a man-made fiber, while also having greater liquid absorbance, lightness, flexibility and resilience like a natural fiber cord.
