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.
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. [3]
Cholesterol clefts of a periapical cyst of the jaw. In light microscopy , periapical cysts show: [ 11 ] Stratified squamous epithelium of variable thickness, except when originating in a maxillary sinus where there is respiratory epithelium (pseudostratified ciliated columnar epithelium).
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.
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.
Odontomas are thought to be the second most frequent type of odontogenic tumor worldwide (after ameloblastoma), accounting for about 20% of all cases within this relatively uncommon tumor category which shows large geographic variations in incidence. According to the same article discussion, statistics might appear misleading as most of the ...
Enucleation of the odontogenic cysts can help, but new lesions, infections and jaw deformity are usually a result. Patients may have numerous BCCs which can be treated surgically or in some patients, with topical medications. The severity of the basal-cell carcinoma determines the prognosis for most patients.
Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments.It is most common in middle-aged females of African descent.
