Amalgam tattoo usually occurs on the mandibular gingiva, often in an area in which an apicoectomy ("root-end filling") with amalgam was carried out. [3]: 138 After the gingiva, the alveolar mucosa and the buccal mucosa are the next most common sites, although any mucosal site in the mouth is possible. [1]
The colour can be uniform or speckled and can appear solitary or as multiple lesions. [1] Depending on the site, depth, and quantity of pigment, the appearance can vary considerably. [2] Oral pigmentation is found in the following places: Lower vermillion border (the exposed pink or reddish margin of a lip [3]) Tongue; Oral mucosa; Gingivae ...
Early lesions may appear as thin, translucent and granular or wrinkled mucosa. [2] [6] The later lesion may appear thicker, more opaquely white and hyperkeratotic with fissures and folds. [6] [2] Oral snuff causes more pronounced changes in the oral mucosa than tobacco chewing. [1] Snuff dipping is associated more with verrucous keratosis. [1]
Smoker melanosis in a patient consuming 2 packs of cigarette per day. Smoking or the use of nicotine-containing drugs is the cause to Smoker's melanosis. [10] [11] Tar-components (benzopyrenes) are also known to stimulate melanocytes to melanin production, and other unknown toxic agents in tobacco may also be the cause.
Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. [2] The differential diagnosis is with leukoplakia , oral candidiasis , oral lichen planus , white sponge nevus , morsicatio buccarum , [ 3 ] hereditary benign intraepithelial dyskeratosis and dyskeratosis congenita.
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [4] [5] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible. The lesion is mostly asymptomatic and color ...
Melanocytic oral lesions are an extremely uncommon condition characterized by pigmented lesions of the mucous membranes. [1]: 807 See also. Mucosal squamous cell ...
Lining mucosa, nonkeratinized stratified squamous epithelium, found almost everywhere else in the oral cavity, including the: Alveolar mucosa , the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs .
