The PDL develops in a cell population from the dental follicle. As the crown approaches the oral mucosa, fibroblasts produce collagen fibrils without organized orientation. Later, prior to tooth eruption, the fibroblasts adopt an oblique orientation adjacent to the cementum. Finally, after this fibroblast arrangement, fibers with organized orientation are developed at the cementum surface as well as at the alveolar bone proper. These fibers will continue elongating until they reach each other at the middle portion of the PDL. The orientation of the fibers will be determined by the location within the PDL (Table 1-1).^4,5
