The presence of the dark lines is similar to the annual rings on a tree. They are named after Swedish anatomist Anders Retzius. In the longitudinal section of a tooth, these lines appear near the dentin. They bend obliquely near the cervical region. They curve occlusally near the cuspal regions or the incisal regions.
Frictional keratosis: This typically presents as white plaques on the oral mucosa due to mechanical trauma. When the cause of frictional keratosis is removed the white patch may resolve. Hyperplastic reactive lesions or nodular swellings: These occur in the oral mucosa due to low grade inflammation or trauma. They develop where the mucosa is ...
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.
This nerve runs inside the mandible, within the inferior alveolar canal below the mandibular teeth, giving off branches to all the lower teeth (inferior dental plexus). [ 5 ] [ 6 ] The oral mucosa of the gingiva (gums) on the facial (labial) aspect of the maxillary incisors , canines and premolar teeth is innervated by the superior labial ...

In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove ) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin .
