Class IV: Recession that extends to or beyond the mucogingival junction, with either loss of interproximal clinical attachment or tooth rotation that is severe A new classification has been proposed to classify gingival and palatal recessions.
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. It may exist with or without concomitant decrease in crown-to-root ratio (recession of alveolar bone). 85% of the world population has gingival recession on at least one tooth with denuded root surface ≥1.0 ...
No disease (gingival pockets < 3 mm) 1: Bleeding on probing, but gingival pockets < 3 mm 2: Periodontal pocketing < 3mm, but calculus (dental) present with or without plaque retentive factors such as "overhanging" restorations 3: Shallow periodontal pockets 4 - 5.5 mm (i.e. first band on probe partially visible) 4
The tip of the instrument is placed with light pressure of 10-20 grams [1] into the gingival sulcus, which is an area of potential space between a tooth and the surrounding tissue. It is important to keep the periodontal probe parallel to the contours of the root of the tooth and to insert the probe down to the base of the pocket .
The EA is very strong in a healthy state, acting as a type of seal between the soft gingival tissue and the hard tooth surface. The deepest layer of the JE, or basal layer, undergoes constant and rapid cell division, or mitosis. This process allows a constant coronal migration as the cells die and are shed into the gingival sulcus.
A non-diseased, healthy gingival sulcus is typically 0.5-3mm in depth, however, this measurement can increase in the presence of periodontal disease. The gingival sulcus is lined by a non-keratinised layer called the oral sulcular epithelium ; it begins at the gingival margin and ends at the base of the sulcus where the junctional epithelium ...
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 ...
Non-plaque-induced gingival disease is an inflammation of the gingiva that does not result from dental plaque, but from other gingival diseases caused by bacterial, viral, fungal, or genetic sources. Although this gingival disease is less common than those which are plaque-induced, it can have a serious impact on the patient's overall health.
