G) Gingival sulcus H) Principal gingival fibers I) Alveolar crest fibers of the periodontal ligament (PDL) J) Horizontal fibers of the PDL K) Oblique fibers of the PDL . 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.
Aural/Ear syringe: used to flush out anything like ear wax or foreign bodies from the external ear Toynbee's auscultation tube: Otoscope/Auriscope: to examine the external auditory canal and ear drum; used during aural toileting, removal of wax, myringotomy, stapedectomy and to dilate the stenosis of canal Mouth gag - •Doyen's mouth gag
The gingival tissue forms a crevice surrounding the tooth, similar to a miniature, fluid-filled moat, wherein food debris, endogenous and exogenous cells, and chemicals float. The depth of this crevice, known as a sulcus , is in a constant state of flux due to microbial invasion and subsequent immune response.
The gingival sulcus (G) is a small crevice that lies between the enamel of the tooth crown and the sulcular epithelium. At the base of this crevice lies the junctional epithelium, which adheres via hemidesmosomes to the surface of the tooth, and from the base of the crevice to the height of the alveolar bone (C) is approximately 2 mm.
In addition, the JE is also thinner than the sulcular epithelium, ranging coronally from only 15 to 30 cells thick at the floor of the gingival sulcus, and then tapering to a final thickness of 3 to 4 cells at its apical part. The superficial, or suprabasal, cells of the JE serve as part of the EA of the gingiva to the tooth surface.
More than 800 species of bacteria colonize oral mucus, 1,300 species are found in the gingival crevice, and nearly 1,000 species comprise dental plaque. The mouth is a rich environment for hundreds of species of bacteria since saliva is mostly water and plenty of nutrients pass through the mouth each day.
Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
Untreated impacted wax can result in hearing loss, social withdrawal, poor work function, and mild paranoia. People with impacted wax may also present with perforated eardrums; this is usually induced by putting objects in the ear in an attempt to remove the wax. [5]
