PURPOSE To evaluate a dental CT software program to determine whether it can provide a better means of assessing odontogenic cysts, lesions of the jaw derived from dental epithelium, than conventional techniques (orthopantomographic, intraoral, and mandibular films), which are of limited usefulness because of the curved configuration of the mandible; and to provide a brief review of these lesio...

Among the odontogenic cysts, there are radicular cysts or also called periapical most common cyst. They develop at apex of a tooth with pulp necrosis, which may be consequence dental caries trauma. they asymptomatic, grow slowly, and discovered on routine radiographs. With proliferation ERM its activation, is an increase in osmotic pressure, causing cyst to expand, normally this not activated, ...

An unusual odontogenic cyst, which was originally believed to be a clinical dentigerous cyst associated with an impacted mandibular third molar, was found histologically to demonstrate the characteristics of a glandular odontogenic cyst with para- and orthokeratinization. These histologic diversities were interpreted as a reflection of the pluripotentiality of the epithelial remnants of the man...

OBJECTIVE To investigate immunohistochemically the expression of neural cell adhesion molecule (NCAM), which has been identified as a signaling receptor with frequent reactivity in ameloblastomas (AB), in a series of keratin-producing odontogenic cysts (KPOCs). MATERIAL AND METHODS Immunohistochemical expression of NCAM, using a monoclonal antibody, was determined in a series of 58 KPOCs comp...

Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT and cited in "pubmed" since 1990 onward were reviewed. AOT accounts for about 1% until 9% of all odontogenic tumors. It is predominantly found in young and female patients, located more often in the maxilla in mos...

PURPOSE To describe the CT and MR findings of various entities causing cystic expansile masses in the maxilla and the significance of the cortical bony plate between the lesions and sinus cavities in the differential diagnosis. METHODS CT findings of 28 patients with cystic expansile masses of the maxilla, including 20 cases of maxillary mucoceles (17 postoperative mucoceles, 2 mucoceles of a...

Dentigerous cysts are the second most common odontogenic cysts after radicular cysts and are most commonly seen in association with third molars and maxillary canines. Only 5% of dentigerous cysts involve supernumerary teeth, of which mesiodens is the most frequent type. This paper presents a case of dentigerous cyst associated with a mesiodens that caused a painless swelling in the upper lip o...

OBJECTIVES Keratocystic odontogenic tumors (KOTs), also known as odontogenic keratocysts, were recently classified as a benign neoplasia due to the aggressive clinical behavior. Although several studies have shown the high proliferative activity of the epithelial lining, few studies have evaluated apoptosis in KOTs. Therefore, the aim of this study is to evaluate and compare the proliferation i...
