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.
Odontogenic cysts are a group of jaw cysts that are formed from tissues involved in odontogenesis (tooth development). Odontogenic cysts are closed sacs, and have a distinct membrane derived from the rest of odontogenic epithelium. It may contain air, fluids, or semi-solid material. Intra-bony cysts are most common in the jaws, because the ...
An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life. [1] Odontogenic keratocysts make up around 19% of jaw cysts. [2] Despite its more common appearance in the bone region, it can affect soft tissue.
H&E stain. Specialty. ENT surgery. Central giant-cell granuloma (CGCG) is a localised benign condition of the jaws. It is twice as common in females and is more likely to occur before age 30. Central giant-cell granulomas are more common in the anterior mandible, often crossing the midline and causing painless swellings. [1]
Oncology, oral and maxillofacial surgery. Ameloblastoma is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. [1] It was recognized in 1827 by Cusack. [2]
Commonly known as a dental cyst, the periapical cyst is the most common odontogenic cyst. It may develop rapidly from a periapical granuloma, as a consequence of untreated chronic periapical periodontitis. [1] Periapical is defined as "the tissues surrounding the apex of the root of a tooth " and a cyst is "a pathological cavity lined by ...
Dentistry. Calcifying odontogenic cyst (COC) is a rare developmental lesion that comes from odontogenic epithelium. [2] It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass.
The calcifying epithelial odontogenic tumor (CEOT), also known as a Pindborg tumor, is an odontogenic tumor first recognized by the Danish pathologist Jens Jørgen Pindborg in 1955. [1] It was previously described as an adenoid adamantoblastoma, unusual ameloblastoma and a cystic odontoma. [1] Like other odontogenic neoplasms, it is thought to ...
