[Antibacterial concentrations in serum and tooth-jawbone tissue following perioperative administration of propicillin].
Antibacterial Concentrations in Serum and Dental Tissues after Preoperative Application of Propicillin. After resecting radicular and follicular cysts in the jaws, the serum, bone, capsule and fluid of the cysts from 40 patients were studied for their propicillin concentration. The patients received 1 Mega unit (0.7 g) propicillin orally as oblong tablets one or two hours before surgery. One or two hours after the application of propicillin, the distribution coefficients between serum and the three tissues were 0.78 and 0.87 for the spongious bone, 0.07 and 0.06 for the cyst capsule and 0.14 and 0.08 for the cyst fluid. The mean concentrations in all three tissues were distinctly above the MICs of the bacteria most frequently isolated from the mouth for at least two hours.
