The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the anterior teeth and a blunted shape buccolingually for the posterior teeth. [1] A missing papilla is often visible as a small triangular gap between adjacent teeth.
The primordium contains each of the primordial tissue types, essential for the development of successive teeth. These primordial tissues together form the enamel organ, dental papilla and dental sac. Also during the cap stage is the formation of a depression within the deepest part of each tooth bud of the dental lamina .
Geometry: Straight interdental brushes are considered more effective compared to angled interproximal plaque removal. Size: This varies depending on the space between individual teeth. Failure to use an appropriate size may account for the lack of efficiency of interdental cleaning aid. [5]
Lesions removed by electrosurgery require an average of 30 to 33 days to heal, whereas lesions removed by surgical curettage require around 21 to 23 healing days. [27] During healing interval, the existing denture can be lined with a temporary tissue conditioner that acts as a palatal dressing and provides greater comfort. [ 26 ]
Acute necrotizing ulcerative gingivitis: painful, bleeding, sloughing ulceration and loss of the interdental papillae (usually of the lower front teeth). Necrotizing periodontal diseases are non-contagious infections but may occasionally occur in epidemic-like patterns due to shared risk factors.
Angularis nigra, Latin for 'black angle', also known as open gingival embrasures, and colloquially known as "black triangle", is the space or gap seen at the cervical embrasure, below the contact point of some teeth. The interdental papilla does not fully enclose the space, leading to an aperture between adjacent teeth. [1]
The dense layer is the deeper layer of the lamina propria. It consists of dense connective tissue with a large amount of fibers. Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae. [10]
Common techniques for removal of the excess tissue include traditional removal with a surgical scalpel, electrical scalpel, or laser excision with a laser scalpel, e.g. a carbon dioxide laser, erbium:YAG laser, Neodymium-YAG laser, or diode laser. [9] The poorly fitting denture can be adapted to fit better (a "reline") or a new denture constructed.
