Ameloblastomas are tumors of odontogenic epithelial origin. The term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. A large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

Peripheral ameloblastoma (PA) is a relatively uncommon odontogenic tumor that is histologically identical to the classic inttaosseous ameloblastoma but it occurs primarily in the soft tissues overlying the toothbearing regions of the jaws and does not exhibit the invasive and aggressive behavior of its intraosseous counterpart.l The origin of PA is thought to be from 1 of 2 sources: extraosseou...

gardner’s syndrome is a genetic condition demonstrating an autosomal dominant trait and characterized by the multiple colonic polyps (familial adenomatous polyposis coli) with sebaceous cysts and jaw osteomas. various dental abnormalities present in patient’s suffering with this syndrome includes multiple impacted or unerupted teeth, supernumerary teeth, hypodontia, compound odontomes and denti...

The jaws are host to a variety of cysts due in large part to the tissues involved in tooth formation. Odontogenic cysts (OCs) are unique in that they affect only the oral and maxillofacial region. There are few studies from sub-Saharan Africa. This study was aimed at describing the pattern of various types of cysts in the oral and maxillofacial region in a Kenyan population. This was done at th...

The goal of this treatment was the surgical- orthodontic rescue of the impacted teeth in a large dentigerous cyst, in a growing patient, by fixed orthodontic appliances. Initial and final records and progress in treatment are shown. The Authors demonstrate that a good result my be reached in this cases even if initial position of the cyst-associated teeth is critical and translocation of an adj...

The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, wh...

BACKGROUND Early diagnosis of odontogenic cysts due to their silent progression is always a challenging problem for clinicians. OBJECTIVES The current study aimed to evaluate the frequency of odontogenic cysts and related factors in a selected Iranian population. PATIENTS AND METHODS The current cross-sectional study was conducted on 312 patients' recorded data in Taleghani Hospital, Tehran...
