Morsicatio buccarumisa lesion determined by a traumatic occlusion. It presents as a translucent, white line with a scalloped appearance, corresponding to the mark made by the dental crowns on the buccal mucosa; it is frequently caused by the interposing of the teeth on the dental arches. Odontoplasty (generally of cutting vestibular cusps)...

Fluid-filled lesion, generally containing serous fluid and greater than 5 mm in diameter. It is situated at different depths of the epithelium (intraepithelial, subdermal and submucosal)

Many drugs or molecules (including amiodarone, ketoconazolo, tetracycline and chlorhexidine) have been associated with the presence of pigmented lesion in the oral cavity. From a pathogenetic point of view, the mechanisms by which this lesion can co-exist varies: 1) a direct depositing on the oral surface; 2) a peripheral accumulation after systemic absorption;...

An abscess is a collection of inflammatory material, deriving from an acute, infective process whose origin is predominantly endo- and/or periodontal. Clinically, it presents as a swelling of varying dimensions, located on the intra-oral and extra-oral levels. An abscess has a fluctuating, hardish-elastic  consistency. It can also communicate externally, following the spontaneous creation of...

Gonorrhoea is a rare, bacterial infection (Neisseria gonorrhoeae), which is sexually transmitted; it can present as a painful swelling. Diagnosis, identification of the bacterium and the prescribing of systemic, antibiotic treatment are all necessary to treat this infection.

Pleomorphic adenoma is the most frequently-occurring, benign neoplasia of the salivary glands. It mainly affects the parotid gland and the submandibular glands. Clinically it presents as a slowly growing swelling, variable in size between 2 and 5cm in diameter. Histologically, pleomorphic adenoma displays a marked variability in appearance: the neoplasia is composed of...

Materia alba is a deposit of disorganised material, milky white in colour, soft and visible to the naked eye. It can accumulate in the cervical area of the teeth and on the oral mucosa. This occurs especially where the mucosal site(s)  is(are) poorly subject to mechanical, self-cleaning mechanisms. Materia alba presents as the persistence of a...

Idiopathic leukoplakia is a white-greyish lesion (patch or plaque), which cannot be removed, being asymptomatic and devoid of pathology. It mainly concern males between 30 and 60 years of age. Typically, the leukoplakia is situated on the underside/margins of the tongue, the floor of the oral cavity but also on the buccal...

Lesion clinically appearing as a red-coloured (erosion), occurring after contact with an irritant (e.g. the ingestion of food or drugs). Once the irritant has been identified, its consumption should be suspended and a hyaluronic gel with amino acids applied. If the lesion does not disappear within 15 days, a biopsy and histo-cytopathological examination are...
