Horizontal fibers (J) attach to the cementum apical to the alveolar crest fibers and run perpendicularly from the root of the tooth to the alveolar bone. Oblique fibers (K) are the most numerous fibers in the periodontal ligament, running from cementum in an oblique direction to insert into bone coronally.
The alveolar crest will be continuous with the lamina dura of the adjacent teeth. When viewing the lamina dura and the periodontal ligament, only the interproximal portions are visible. The buccal and lingual areas are not seen in the radiograph. Widening of the periodontal ligament space and loss of lamina dura can be interpreted as resorption of the alveolar bone.
