Bohn’s nodules, described by Heinrich Bohn in 1886 as "mucous gland cysts", are distributed over the junction of the hard and soft palate. They are derived from minor salivary glands. They are found at the junction of the hard and soft palate, and along lingual and buccal parts of the dental ridges, away from the midline. These nodules are 1 ...
Congenital epulis is a proliferation of cells most frequently occurring on the alveolar ridge of the upper jaw at birth. Less frequently, the mass may arise from the mandibular alveolus.
Jaw cysts affect around 3.5% of the population. 10 They are more common in males than females at a ratio of 1.6:1 and most people get them between their 40s and 60s. The order of the jaw cysts from most common to least common is; radicular cysts , dentigerous cysts , residual cysts and odontogenic keratocysts .
[1] [2] The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence is found in the only study that relies on personal examination of patients. [3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]
Epulis (Greek: ἐπουλίς; plural epulides) is any tumor-like enlargement (i.e. lump) situated on the gingival or alveolar mucosa. [1] [2] The word literally means "(growth) on the gingiva", [3] [4] and describes only the location of the mass and has no further implications on the nature of the lesion. [5]
It can be sessile or pedunculated with the size usually being less than 2 cm. The lesion has a 60% gender predilection to females. The prevalence of the peripheral giant-cell granuloma is highest around 50 - 60 years of age. It appears only on the gingiva or on an edentulous alveolar ridge.
An unusual variant is the cervical ranula (also called a plunging or diving ranula), where the swelling is in the neck rather than the floor of the mouth. [1] The term ranula is also sometimes used to refer to other similar swellings of the floor of mouth such as true salivary duct cysts, dermoid cysts and cystic hygromas. [1]
It is a classed as a pseudocyst, [1] since there is no epithelial lining or fluid content. This defect is usually considered with other cysts of the jaws, since it can be mistaken for such on a radiograph. Two classification systems were proposed to categorize Stafne bone cavity based on its depth [2] and content. [3]
