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...

background. the aim of this study was to investigate myofibroblast (mf) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of mfs and the clinical behavior of these lesions. methods. a total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (uam), solid ameloblastoma (sa), odontogenic keratocyst (okc), dentigerous cyst (dc), rad...

odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. the lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

background and aims. odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. since definite diagnosis is difficult in some cases, it has been suggested that cd56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. the present study was designed to examine cd56 expression in lesions with histopatho...

peripheral calcifying cystic odontogenic tumor (pccot) is a rare odontogenic lesion, which represents about 1% of jaw cysts. here we report clinicopathologic, radiographic and ct scan images of a new case of recurrent large pccot located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. in reviewing the li...

in 1991, handlers and colleagues described the central odontogenic fibroma (cof) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. cof usually occurs in an adult patient and has a predilection for the anterior region of the jaws. a 2.8:1 female to mail ratio is typically noted. this article presents a case of cof in a ...

odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

Classification: The following classification is based upon the inductive effect of one dental tissue upon another. In normal tooth development, it has been observed that ameloblastic epithelium exerts an influence upon the undifferentiated mesenchymal cell of the dental papilla "inducing" adjacent cells to further differentiate into odontoblasts. The odontoblasts then begin to form dentine. The...

Odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. Odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. The lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

background and aim: the inferior alveolar canal must be constantly examined as an important anatomical landmark in the study of lower jaw, particularly posterior body and mandibular ramus sites, in dental and surgical procedures. in the present study, the effect of two pathological lesions, ameloblastomas and keratocystic odontogenic tumour, on canal displacement were investigated. materials an...
