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].

The nasopalatine duct cyst (NPDC) is the most common of the non-odontogenic cyst of the jaws. This cysts are usually central or unilateral with no prevalence of side occurrence. The NPDC is the most frequent developmental, nonodontogenic cyst of the jaws. This cyst originates from epithelial remnants from the nasopalatine duct. The cells could be activated spontaneously during life, or are even...

Introduction: Dentigerous cysts (DCs) are the most common developmental cysts of the jaws, mostly associated with impacted third molars and canines. Multiple or bilateral DCs are rare and typically occur in association with some syndromes including cleidocranial dysplasia and Gorlin-Goltz. The occurrence of multiple DCs is rare in the absence of these syndromes. Case Presentation: A 28-year-ol...

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...

background: keratocystic odontogenic tumor (kcot) is a developmental odontogenic cyst on which various investigations have been focused due to its biological activities, high tendency to recur and different growth mechanisms in comparison with other cystic lesions. previous studies have shown different biological and proliferative activities for the lining epithelium of kcot. the aim of this st...
