title: Cephradine penetration of mandibular bone.
abstract: The concentration of cephradine in serum and mandibular bone was assayed in 22 patients undergoing third molar surgery following a single 1-g intramuscular injection. Serum and cortical bone samples taken simultaneously contained mean cephradine concentrations of 12.41 micrograms/mL and 1.25 micrograms/g, respectively. These results, when compared with those reported for other bony sites, including femoral head and knee, show a reduced bone penetration with a bone-to-serum ratio of approximately 0.10:1.
