BACKGROUND The purpose of this study was to assess and compare angiogenesis in ameloblastoma, keratocystic odontogenic tumors, dentigerous cysts, and normal oral mucosa. METHODS Angiogenesis was assessed in 28 ameloblastoma-36 keratocystic odontogenic tumors, 28 dentigerous cysts, and 19 normal oral mucosa by measuring the mean vascular density (MVD), total vascular area (TVA) and mean vascul...

OKC is the rare and noteworthy developmental odontogenic cyst which arises from dental lamina. Around 7.8% of all cysts jaw are categorized in to this type grow an antero-posterior direction medullary cavity bone without causing expansion until & unless when large. The frequent location mandibular posterior body. It uncommon maxilla only 13% occur anterior region. An interesting case maxill...

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...

conclusions the current study showed that clinicians should consider the many factors associated with the occurrence of odontogenic cysts. 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,...

AIM Though odontogenic lesions have in common origin from the primitive odontogenic epithelium , there is a diversity in their initiation behavior and growth. The aggressive nature of odontogenic keratocyst similar to ameloblastoma in comparision with the other common odontogenic (dentigerous and radicular) cyst could be due to possible differences in their epithelial linings. PCNA (Proliferati...

OBJECTIVE The aim of the study was to determine the apoptotic features and proliferation potential of odontogenic keratocysts compared with ameloblastomas and radicular cysts by analysing the role of bax, bcl-2, and Ki-67. MATERIAL AND METHOD The study material consisted of 20 odontogenic keratocysts, 20 radicular cysts, and 20 ameloblastomas. Immunohistochemically, bax, bcl-2 and Ki-67 were ...

Background: Impacted tooth is common in dental practice. Dentists usually remove them if they are associated with any pathologic sign or symptom. The challenge is whether to extract the asymptomatic tooth or not. This study was conducted to determine the association between developmental odontogenic cysts and tumors and impacted and unerupted teeth, if left untreated.    Methods: In ...

SUMMARY Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma.

Objectives The aim of the present study was to document the frequency and clinicopathologic features of intra-osseous jaw lesions in an Iranian pediatric population over a 20-year period. Methods Data were obtained from the archives of the Oral Pathology Department, Shahid Beheshti University of Medical Sciences, Tehran, Iran. The lesions were classified into four groups: (A) odontogenic cysts...

OBJECTIVE Cystic ameloblastoma, keratocystic odontogenic tumor, dentigerous cyst, and radicular cyst are the most commonly encountered cystic odontogenic lesions. The aim of this study was to investigate the expressions of survivin, E-cadherin, CD138, and CD38 in these lesions and their potential diagnostic usage. MATERIAL AND METHOD A total of 20 cases, consisting 5 radicular cysts, 5 dentig...
