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 .
In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain , but also in the lungs , certain muscles (including the heart ), as well as ...
The gingival cavity microecosystem, fueled by food residues and saliva, can support the growth of many microorganisms, of which some can be injurious to health. Improper or insufficient oral hygiene can thus lead to many gum and periodontal disorders, including gingivitis or periodontitis, which are major causes for tooth failure.
In dental anatomy, the junctional epithelium (JE) is that epithelium which lies at, and in health also defines, the base of the gingival sulcus (i.e. where the gums attach to a tooth). The probing depth of the gingival sulcus is measured by a calibrated periodontal probe.
Using the mucogingival junction as the boundary demarcating the apical border of the attached gingiva, a periodontal probe is inserted into the gingival sulcus to measure how much of the keratinized gingiva coronal to the mucogingival junction is in fact attached to the underlying bone. The depth of the gingival sulcus, determined by the depth ...
Each of these components is distinct in location, architecture, and biochemical properties, which adapt during the life of the structure. For example, as teeth respond to forces or migrate medially, bone resorbs on the pressure side and is added on the tension side. Cementum similarly adapts to wear on the occlusal surfaces of the teeth by ...
The oral epithelium (E) exists on the other side of the free gingival margin. In dental anatomy, the sulcular epithelium is that epithelium which lines the gingival sulcus. [1] It is apically bounded by the junctional epithelium and meets the epithelium of the oral cavity at the height of the free gingival margin.
When mechanical stimuli are introduced to the cells, osteocytes in the PDL will differentiate into osteoclasts which will then reform and remodel the bone structure in the affected area. For example, orthodontic treatment involves application of a mechanical force on to the teeth to align them and this is done through this complex combination ...
