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.
[13] [2] Protein content of cyst fluid below 4g% is diagnostic of odontogenic keratocysts. [2] Smaller and unilocular lesions resembling other types of cysts may require a biopsy to confirm the diagnosis. [10] On a CT scan, the radiodensity of a keratocystic odontogenic tumour is about 30 Hounsfield units, which is about the same as ...
Periapical cysts have a characteristic unilocular [8] shape on radiographs. There is also a severe border of cortication [ 9 ] between the cyst and surrounding bone. Pseudocysts, on the other hand, have a fluid filled cavity but are not lined by epithelium, therefore they have a less severe and more blurred border between the fluid and bony ...
Lateral periodontal cysts (LPCs) are defined as non-keratinised and non-inflammatory developmental cysts located adjacent or lateral to the root of a vital tooth.” [1] LPCs are a rare form of jaw cysts, with the same histopathological characteristics as gingival cysts of adults (GCA). Hence LPCs are regarded as the intraosseous form of the ...
Radiographically, the tumour area appears as a rounded and well-defined lucency in the bone with varying size and features. Numerous cyst-like radiolucent areas can be seen in larger tumours (multi-locular) giving a characteristic "soap bubble" appearance. A single radiolucent area can be seen in smaller tumours (unilocular). [8]
This type of bone cyst is a condition found in the long bones and jaws. [13] There is no definitive cause, though it relates to trauma in the oral region. The likelihood of males being affected by this condition is frequently greater than in females. It appears on radiographs as a unilocular radiolucent area with an irregular but well-defined ...
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.
A glandular odontogenic cyst (GOC) is a rare and usually benign odontogenic cyst developed at the odontogenic epithelium of the mandible or maxilla. [2] [8] [9] [10] Originally, the cyst was labeled as "sialo-odontogenic cyst" in 1987. [7] However, the World Health Organization (WHO) decided to adopt the medical expression "glandular ...
