Isotope fractionation and particle distribution methods were used in conjunction to quantitate blood flow in the oral mucosa, alveolar bone, tongue, masseter muscle, and dental pulp. Infiltration of epinephrine in lidocaine (Xylocaine) and lidocaine alone and inhalation of 5% CO₂ provided experimental conditions to alter flow in some tissues.
