Sections of the jaws from marmosets of all ages were impregnated with silver nitrate to demonstrate the intrabony course of the alveolar fibers of the periodontal ligament. As the interseptal bone undergoes a period of resorption and apposition, the intrabony alveolar fibers also are lost and reformed. Age changes were noted in the insertion depth of the alveolar fibers. A continuum of fibers traversing the alveolar septum could not be determined.
