A systematic review of the literature from 1993 to 2011 was undertaken examining frequency data of the most common odontogenic cysts and tumors. Seven inclusion criteria were met for the paper to be incorporated. In the preliminary search 5231 papers were identified, of these 26 papers met the inclusion criteria. There were 18 297 odontogenic cysts reported. Of these there were 9982 (54.6%) rad...

A 63 year-old male with a huge odontogenic lesion of sinus maxillaris was treated with computer-assisted surgery. After resection of the odontogenic lesion, the sinus wall was reconstructed with a prebended 3D titanium-mesh using CAD/CAM technique. This work provides a new treatment device for maxillary reconstruction via rapid prototyping procedures.

BACKGROUND WHO has recently renamed odontogenic keratocyst as keratocystic odontogenic tumour (KCOT) depending on its tumour like behaviour. AIM To quantitate and qualitate different types of collagen fibers in KCOT using picrosirius red stain under polarising microscopy and to correlate with different radiographic patterns of KCOT to elucidate its biological behaviour in order to determine w...

Since its first publication in 1975, the squamous odontogenic tumor remains the rarest odontogenic lesion, with around 50 cases in the English-language literature in which the microscopic characteristics are frequently very well demonstrated. However, articles which discuss the radiographic aspects are scarce, especially with emphasis on the differential diagnosis. The present treatise proposes...

Odontogenic keratocyst is one of the most aggressive odontogenic cysts with a high recurrence rate, this was explained histopathologically as it typically shows a thin, friable wall, which is often difficult to enucleate from the bone in one piece, and have small satellite cysts within the fibrous wall. Multiple surgical approaches were introduced including decompression, marsupilization, enucl...

Although odontogenic keratocysts (OKCs) are benign, they are often locally destructive and tend to recur after conservative surgical treatment. They must therefore be distinguished from other cysts of the jaw. Keratocysts possess outpouchings and microscopic daughter cysts from which recurrences may arise. Histologic examination is essential for diagnosis since the appearances on roentgenograms...

Odontogenic keratocysts (OKCs) are one of the most frequent features of nevoid basal cell carcinoma syndrome (NBS). It is linked with mutation in the PTCH gene. Partial expression of the gene may result in occurrence of only multiple recurring OKC. Our patient presented with nine cysts with multiple recurrences over a period of 11 years without any other manifestation of the syndrome.

PURPOSE Multicystic ameloblastoma is a benign epithelial odontogenic tumor that exhibits a more aggressive behavior than follicular cyst and keratocystic odontogenic tumor (KCOT). The aim of this study was to perform an immunohistochemical evaluation of the mean microvessel density (MVD) effect on clinical behavior of odontogenic lesions and to determine whether peritumoral or intratumoral MVD ...

KCOT is one of the most aggressive odontogenic cysts with a high recurrence rate, this was explained histopathologically as it typically shows a thin, friable wall, which is often difficult to enucleate from the bone in one piece, and have small satellite cysts within the fibrous wall. Multiple surgical approaches were introduced including decompression, marsupilization, enucleation with or wit...

OBJECTIVE To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. STUDY DESIGN A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayis University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and hist...
