On CT imaging, a mandibular dentigerous cyst appears as a well-circumscribed unilocular area of osteolysis that incorporates the crown of a tooth. Displacement of adjacent teeth may be seen and they may be partly eroded. Dentigerous cysts in the maxilla often extend into the antrum, displacing and remodeling the bony sinus wall.
A cystectomy is the removal of a cyst followed by mucosa and wound closure to reduce chances of cyst regeneration. This type of treatment is more ideal for small cysts. [citation needed] A cystostomy is recommended for larger cysts that compromise important adjacent anatomy. The cyst is tamponaded to allow for the cyst contents to escape the bone.

Parasitic cysts: hydatid cyst; Cysticercus cellulosae; trichinosis; Buccal bifurcation cyst; Calcifying odontogenic cyst; Dentigerous cyst (associated with the crowns of non-erupted teeth) Glandular ...
Odontogenic keratocysts are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as residual cysts or a dentigerous cyst if they occur over an unerupted tooth. [8] Relative incidence of odontogenic cysts. [9]
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.
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.
Odontogenic cysts are a less common pathology of the impacted wisdom tooth with some estimates of prevalence from 0.64% to 2.24% of impacted wisdom teeth. [37] [38] They are described as ‘cavities filled with liquid, semiliquid or gaseous content with odontogenic epithelial lining and connective tissue on the outside’. However, studies have ...
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
