objective: the ortho keratinized odontogenic cyst (ooc) is a rare lesion originates from dental lamina and clinically, it may be mistaken for many other odontogenic cysts and tumors. microscopically, it should be distinguished from kcot because of differences in biologic behavior and histologic features.   case: an interesting case of ooc arising in the edentulous mandibular right first premola...

The Glandular Odontogenic Cyst (GOC) is a rare developmental odontogenic cyst that occurs 75% of the time in the mandible and rarely presents in persons under 20 years of age [1]. The GOC was originally described by Padayachee and Van Wyk [2] in 1987 who reported on two cases of multilocular mandibular cysts with features of both Botryoid Odontogenic Cyst (BOC)and central mucoepidermoid tumor (...

The calcifying odontogenic cyst represents a heterogeneous group of lesions that exhibits a variety of clinicopathologic and behavioral features. Therefore, a proper categorization of the cases is needed for better understanding of each variant. Ameloblastoma is one of the well-known odontogenic tumors that could be associated with calcifying odontogenic cyst. Very few cases of ameloblastomatou...

the term calcifying odontogenic cyst (coc) was first introduced by gorlin in 1962. coc occurs mainly as an intra-osseous lesion in mandible or maxilla but the peripheral variation of coc has also been reported. the confusion about coc nature as cyst or tumor has not been resolved and a vast diversity has been shown in clinicopathologic aspects of coc. the purpose of this study was the review an...

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...

The glandular odontogenic cyst is an uncommon developmental odontogenic cyst described as a distinct entity by Gardner et al. in 1988. The Glandular odontogenic cyst occurs more commonly in middle-aged people and has a predilection for the mandible. Only histopathological examinations allow for certain diagnosis of the cyst. The increased recurrence rate can be due to its multilocularity and in...

Odontogenic cysts constitute a major part of oral pathological lesions, but little is known about their distribution patterns in various populations. In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Pathology at the Faculty of Dentistry affiliated to the Tehran University of Medical Sciences were reviewed. Cases diagnosed as odontogenic c...

INTRODUCTION The lateral periodontal cyst, as the name implies, occurs on a lateral periodontal location and is of developmental origin, arising from cystic degeneration of clear cells of the dental lamina. A botryoid odontogenic cyst is considered to be a rare multilocular variant of a lateral periodontal cyst. CASE PRESENTATION We report the clinical and histopathologic features of a rare c...

BACKGROUND AND AIMS The aim of this study was to investigate the relative frequency of developmental odontogenic cysts in an Iranian population. MATERIALS AND METHODS In this study 245 cysts from both jaws, treated in the Faculty of Dentistry at Tabriz University of Medical Sciences during a 10-year period from 1998 to 2008, were analyzed in order to evaluate the incidence of such cysts. We h...
