It is a very thin, black-blue line visible along the margin of the gums, at the base of the teeth. [1] [2] It is caused by the reaction between circulating lead and sulphur ions produced by oral bacteria, forming deposits of lead sulfide in the gums. [3] The sign was described in 1840 by Henry Burton: [4]
The mandibular notch, also known as the sigmoid notch, is a groove in the ramus of the mandible. It is the gap between the coronoid process anteriorly and the condyloid process posteriorly. Structure
Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10.
1) Enamel 2) Dentin 3) Junctional epithelium 4) Connective tissue 5) Alveolar bone 6) Gingival margin 7) Sulcular epithelium 8) Gingival epithelium 9) Cementum The dentogingival tissues consist of many constituents, such as the enamel or cementum of the tooth and the connective tissue supporting epithelia like the junctional epithelium, the gingival epithelium and the sulcular epithelium.
Noticeable signs include receding gums,making the teeth appear longer. Gums may bleed more, and there may be some bone loss. Moderate periodontitis: As the gum disease progresses, pockets get ...
Sparacino does all she can to ensure her gums and teeth stay as healthy as possible. For example, she uses an extra-strength toothpaste designed for people at higher risk of cavities and tooth ...
If only 1 tooth is present in a sextant, the tooth is included in the adjoining sextant. The probe is "walked around" measuring the depth of the gingival crevices/periodontal pockets (the gap between the tooth and the gums, "below the gumline") with a force of approximately 20 - 25 gm (20 - 25 N) (about the force using when writing with a pencil).
In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned tissues in their various states of health and disease.
