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...

BACKGROUND & OBJECTIVES Odontogenic cysts are among the most frequent destructive lesions of jaws which their pathogenesis and growth mechanism are not cleared. With respect to different roles of mast cells, they may play a role in the pathogenesis and growth of odontogenic cysts. The aim of present study was to evaluate mast cells in the most common odontogenic cyst. METHODS Thirty paraffin-...

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 ...

OBJECTIVES The purpose of this retrospective study is to find the differentiating characteristics of cystic and cystic-appearing lesions that involve the impacted mandibular third molar by analyzing panoramic radiographs and computed tomography images, and to aid the preoperative diagnosis. MATERIALS AND METHODS Eighty-one patients who had a mandibular cystic or cystic-appearing lesion that i...

A dentigerous cyst or follicular cyst is an odontogenic cyst thought to be of developmental origin associated with the crown of an unerupted tooth. Such cyst remain initially asymptomatic unless infected. The purpose of this case report is to describe the diagnosis and management of dentigerous cyst in a 7.5 year-old boy. The chosen treatment was marsupialization which responded well with erupt...

Introduction: Glandular odontogenic cyst (GOC) is uncommon jaw cyst of odontogenic origin with unpredictable and potentially aggressive behavior. It is a rare developmental cyst with relatively low frequency of just 0.012–0.03%. Very limited cases of GOC have been reported in literature since it was first described by Gardner et al. in 1988. GOC is found to occur in fifth decade of life and the...

Nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst occurring inferior to the nasal alar region. The patient usually presents with a slowly enlarging asymptomatic swelling, typically without radiographic abnormalities. This paper documents the presentation and management of a 46-year-old woman with a nasolabial cyst. The histopathologic features, differential diagnosis, t...

OBJECTIVE The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. MATERIAL AND METHOD In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 amel...
