Adenomatoid odontogenic tumor is a relatively uncommon distinct odontogenic neoplasm. It is an uncommon tumor of odontogenic origin with varying number of ductlike structures and inductive changes in the stroma. It is a benign and slow growing epithelial tumor and represents 3% of all odontogenic tumors. Its occurrence is more common in anterior region of the maxilla than mandible. Most of the ...

Objective: To assess the thickness and color of collagen fibres in various odontogenic cysts for its possible role in expansion. Study design: 49 cases of 4 types of odontogenic cysts and 5 normal mucosal tissues were selected as the study and the control group respectively. All slides were stained with both Hemotoxylin and Eosin and the picrosirius red stain. The thickness of collagen fibres w...

Adenoameloblastoma or adenomatoid odontogenic tumor (AOT) is an uncommon, benign, epithelial lesion of odontogenic origin. It is a rare benign odontogenic tumor of the jaw affecting mostly young individuals with predominance in female. It occurs mostly in maxillary anterior region. On the basis of clinical and radiographical picture, it is often misdiagnosed as an odontogenic cyst. We report on...

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity with or without luminal and/or mural tumor growth. It accounts for 5 to 15% of all intraosseous a...

Radicular cyst is the most common odontogenic cystic lesion of inflammatory origin. It is also known as periapical cyst, apical periodontal cyst, root end cyst, or dental cyst. It arises from epithelial residues in the periodontal ligament as a result of inflammation. The inflammation usually follows the death of dental pulp. This paper presents a case report of a patient with radicular cyst as...

odontogenic fibromyxoma is a rare and locally-invasive benign neoplasm found exclusively in the jaws. it has the potential for extensive bony destruction and extension into the surrounding structures. in the presented case, radiographic and histological features as well as the treatment and follow-up of odontogenic fibromyxoma accompanying odontogenic cyst of mandible in an 8-year-old boy are d...

abstract introduction. p53 has been known as a tumor suppressor gene and also ki-67 is a cell cycle regulator. the aim of present study was to investigate p53 and ki-67 protein expression in the epithelial lining of odontogenic cysts and its correlation with their biologic behavior and the degree of inflammation within the cyst wall. methods. p53 and ki-67 immunoreactivity in 58 odontogenic cys...

introduction calcifying odontogenic cyst (coc) is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid) variant. case presentation this case report presents multiple coc, which involved the maxillary bone and sinus in a 30-year-old man. several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed sur...
