What are the pathologic manifestations of dentigerous cyst?

Bilateral buccal bifurcation cysts. Enlarged dental follicles. Multiple hyperplastic calcifying follicles. Mucolipidosis Type III, or pseudo-Hurler polydystrophy.

What are the pathologic manifestations of dentigerous cyst?

Bilateral buccal bifurcation cysts. Enlarged dental follicles. Multiple hyperplastic calcifying follicles. Mucolipidosis Type III, or pseudo-Hurler polydystrophy.

What causes dentigerous cyst?

Dentigerous cysts are caused by a buildup of fluid over the top of an unerupted tooth. The exact cause of this buildup is unknown. While anyone can develop a dentigerous cyst, they’re more common in people who are in their 20s or 30s.

What is a cyst oral pathology?

Odontogenic cysts are pathological cavities located in the jaw bones, filled with fluid surrounded by epithelial lining and fibrous connective tissue. Two most common odontogenic cysts with epithelial lining are inflammatory and developmental cysts (Figure 1).

What is odontogenic pathology?

Odontogenic tumors · Bone pathology. Introduction. Developmental anomalies of teeth affect tooth number, shape, and/or the quality of the dental tissues. Tooth anomalies consequent to abnormal development are a heterogeneous, diverse group arising as a result of genetic and/or environmental insults.

How many types of Dentigerous cysts are there?

Two types of dentigerous cysts are reported in the literature: Developmental and inflammatory types. The developmental type of these cysts is the most common type, which surrounds the crown of an unerupted tooth by the fluid accumulation between the layers of the enamel organ.

How do you tell the difference between ameloblastoma and dentigerous cyst?

Although the presence of a tooth within a lucent mass is pathognomonic for a dentigerous cyst, the aggressive features of portions of the mass and the presence of solid enhancing nodular foci were inconsistent with this type of cyst. Thus, ameloblastoma was the primary differential diagnosis.

What is dentigerous cyst?

Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ.

What is a dentigerous cyst?

How can you distinguish between dentigerous cyst and hyperplastic tooth follicle?

The true differential diagnosis between hyperplastic dental follicle and dentigerous cyst should be made by radiographic correlation. Most authors suggest that to qualify as a dentigerous cyst, the space between the tooth and the follicle should be >3–4 mm.

What is Dentigerous cyst?

How can you distinguish between Dentigerous cyst and hyperplastic tooth follicle?

Why dentigerous cyst is called follicular cyst?

Dentigerous cyst, also known as follicular cyst is an epithelial-lined developmental cyst formed by accumulation of fluid between the reduced enamel epithelium and crown of an unerupted tooth.

How many types of dentigerous cysts are there?

What is the management of dentigerous cyst?

Dentigerous cysts are generally treated by surgical means. The most common surgical modalities used are total enucleation,2 marsupialization,4, 5 and decompression of the cyst via fenestration.

What is the treatment of dentigerous cyst?

Though the usual treatment for a dentigerous cyst is careful enucleation of the cyst together with the removal of unerupted tooth, if eruption of the unerupted tooth is considered feasible, the tooth may be left in place after partial removal of the cyst wall.

Is dentigerous cyst unilocular or multilocular?

The radiographic appearance of a dentigerous cyst is usually that of an unilocular, non-expansile radiolucency characterized by well-defined borders and is always associated with the crown of an impacted tooth, most often a third molar. Dentigerous cysts range in size from 5mm to 7cm or even larger.

What is marsupialization of dentigerous cyst?

Marsupialization is a conservative surgical intervention that decreases the size of the cyst gradually. The procedure involves making a window on the cystic wall by incision, evacuation of the contents of the cyst, and suturing the cystic lining to the oral mucosa.

What is the difference between dentigerous cyst and ameloblastoma?

Ameloblastomas may arise from various sources of odontogenic epithelium, including the epithelial lining of the dental follicle (Table) (3,4). Approximately 50% of ameloblastomas arise from the epithelial lining of a dentigerous cyst (4). Dentigerous cysts are the most common noninflammatory odontogenic cysts (4).

What is enucleation and marsupialization?

Cysts are usually enucleated, where the cystic lining is separated from its inner bony surface and removed and the cavity allowed to fill with blood clot. Alternatively the cyst may be marsupialized to relieve the internal pressure.
