Foreign body giant cell reaction related to placement of tetracycline-treated polylactic acid: report of 18 cases.
Presented are 18 cases of foreign body giant cell reaction in mandibular third molar extraction wounds previously treated with 40 mg of dry tetracycline powder carried into the wound with a biodegradable polymer dressing. The lesions vary in intensity from local, soft tissue granulomas to osteolytic, central bone pathologies. Several reports of foreign body giant cell reaction to insoluble tetracycline preparations are cited, along with a brief review of the relationship between myospherulosis and various formulations of tetracycline powder in petroleum-based carrier vehicles. The authors suggest that the foreign body giant cell lesions reported here were initiated by micron-sized particles of insoluble tetracycline powder and were further aggravated by certain hydrophobic characteristics of the associated biodegradeable polymer. The authors caution against use of dry, powdered forms of topical antibiotics in fresh dental extraction wounds.
