OBJECTIVE The aim of this study was to determine the prevalence of odontogenic jaw cysts in a Libyan population and to compare the data with previously published reports from other countries. MATERIALS AND METHODS We retrieved and analyzed 2190 case notes and biopsy records of the Department of Oral and Maxillofacial Surgery and the Department of Oral Pathology and Microbiology, Al Arab Medic...

The authors present two cases of calcifying odontogenic cysts, which were confirmed by histological examination. In the first case the radiographic findings and clinical status did not indicate the presence of a calcifying odontogenic cyst. In the second case, differential diagnosis included COC. The histopathological findings showed that what appeared to be simple cases of bone translucencies ...

Introduction: Cysts of the jaw are a recognized clinical entity for a long time and are a benign bone destroying lesion. Their remains a diagnostic ambiguity between cysts and cyst-like lesions of the jaws. Objective: The main objective of this study was to assess the total soluble protein content in fluid aspirates of intra osseous cyst of maxilla and mandible. Materials and Methods: A total n...

Odontogenic cysts are pathological cavities enclosed by fibrous connective tissue and lined with epithelial that develops from odontogenic tissues in the maxilla mandible's tooth-bearing regions. Trauma or tooth caries is main cause of radicular periapical cysts. Pulp necrosis outcome dental irritating pulp cavity. Once infection has reached root's tip, it causes periodontitis, which may lead t...

The aim of this study was to investigate whether there is any association between inflammation and the expression of markers of cell cycle entry (Ki-67 and MCM-2) in dental follicle (DF) of asymptomatic impacted teeth and odontogenic cysts. The study consisted of 70 DFs and 20 odontogenic cysts (radicular cyst (RC), dentigerous cyst (DC) and keratocytic odontogenic tumor (KCOT) located at poste...

Among cysts of inflammatory origin, radicular and follicular are most often found in children. Follicular with a frequency 35.5-42% among all odontogenic between the ages 7 14 years. It was that localization cyst depends on age: children, lower premolars (20.8%) upper canines (10%) more causal, adults, third molars (23.3%) (18.3 %). Cysts from rudiments deciduous teeth quite rare [1].

Dentigerous cysts are developmental odontogenic cysts and are always associated with an unerupted or developing tooth bud. Mesiodens is a supernumerary tooth found in the anterior maxilla. Supernumerary teeth seldom associate with dentigerous cysts and dentigerous cysts around supernumerary teeth account for 5% of all dentigerous cysts. Here we report a case of dentigerous cyst in association w...

Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. Dentigerous cysts surrounding impacted teeth often displace teeth into ectopic positions. In the maxilla, these teeth are often displaced into the maxillary sinus. We report 3 cases of dentigerous cysts associated with an ectopic tooth in the maxillary sinus and review the literature reports o...
