Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. [2] In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. [3]
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. 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.

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.
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).
Heavy staining and calculus deposits exhibited on the lingual surface of the mandibular anterior teeth, along the gumline Calculus deposit (indicated with a red arrow) on x-ray image. In dentistry, calculus or tartar is a form of hardened dental plaque.
It manages cleans effectively without excess pressure along the gum line, where gum disease tends to start forming. See it! One of the most innovative features of the ExpertClean 7500 is its app ...
After extraction of a tooth, the clot in the alveolus fills in with immature bone, which later is remodeled into mature secondary bone. Disturbance of the blood clot can cause alveolar osteitis, commonly referred to as "dry socket". With the partial or total loss of teeth, the alveolar process undergoes resorption.
Its medial surface gives insertion to the temporalis, and presents a ridge which begins near the apex of the process and runs downward and forward to the inner side of the last molar tooth. Between this ridge and the anterior border is a grooved triangular area, the upper part of which gives attachment to the temporalis, the lower part to some ...
