  • Patent number: 4357935
    Abstract: A dressing for use in treating dry socket syndrome resulting from tooth extraction includes a gauze strip impregnated with a gelatinous material containing petrolatum, emulsifiers and an analgesic substance such as eugenol. In the process of making and packaging the dry socket dressing, a strip of gauze is unrolled from a roll and passed through a bath containing a gelatinous material at a rate to permit a six-inch length of gauze to incorporate approximately two grams of gelatinous material. The impregnated strip is then cut into predetermined lengths and thereafter packaged in a transparent, sealed envelope. The package containing the dry socket dressing is then treated with gamma radiation to sterilize the dressing and interior of the envelope.
