Radicular cysts (RCs) show distinct histopathological findings may be lined wholly or in part by non-stratified squamous epithelium, the scar fibrous connective tissue, few unexpected neoplasms have been reported and this an important insight into the knowledge of the histological variations of RCs. A total of 115 cases of RCs from the archives of Department of Oral Pathology evaluated for diff...

BACKGROUND It has been demonstrated that HER3 plays an important role in some human cancers and the HER3 expression is associated with worse survival in solid tumors. OBJECTIVES This study was conducted to compare HER3 expression in epithelial lining of radicular cysts (RCs), dentigerous cysts (DCs) and odontogenic keratocysts (OKCs). MATERIALS AND METHODS This was a descriptive-analytical ...

p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC), 23 keratocystic odontogenic tumors (KC...

Glandular odontogenic cyst (GOC) is a rare aggressive developmental cyst of the jaw. It most commonly occurs in middle-aged people with mandible anterior region being the most affected site. This lesion can present as a unilocular or multilocular radiolucency and has high recurrence rate. The histopathologic features of the GOC are complex and often coincide with the features of dentigerous cys...

Glandular odontogenic cyst (GOC) is considered an odontogenic cyst of developmental origin, which because of its histological features had been termed sialo-odontogenic cyst. Although clinically and radiologically they bear similarity to relatively innocuous periapical lesions, their biological behavior is comparable to aggressive tumor-like conditions-like keratocystic odontogenic tumors. Thei...

The nasopalatine cyst is the most common epithelial and nonodontogenic cyst of the maxilla. The cyst originates from epithelial remnants from the nasopalatine duct. The cells may be activated spontaneously during life or are eventually stimulated by the irritating action of various agents (infection, etc.). It is different from a radicular cyst. The definite diagnosis should be based on clinica...

reatment of molar radicular cysts is challenging and many olars may be removed if endodontic treatment is unsucessful. Conventional periradicular surgery of molars is not lways done, because of the technical difficulties and poor isualisation. Endoscopic periradicular surgery (EPS) has een introduced to avoid having to remove molars.1–3 If lling of the root canal is insufficient, we use EPS aft...

BACKGROUND Odontogenic cysts and tumors of the maxilla may be amendable to management by endonasal endoscopic techniques, which may reduce the morbidity associated with open procedures and avoid difficult reconstruction. OBJECTIVE To perform a systematic review that evaluates the feasibility and outcomes of endoscopic techniques in the management of different odontogenic cysts. A case series ...
