Dermoid cysts (DMCs) and epidermoid cysts (EDMCs) usually arise in soft tissues, whereas orthokeratinized odontogenic cysts (OOCs) and keratocystic odontogenic tumors (KCOTs) develop in the jaw. In this study, we performed immunohistochemical analysis of cytokeratins (CKs) to examine differences in the lining epithelium of DMCs, EDMCs, OOCs, and KCOTs. In addition, we carried out immunohistoche...

The dentigerous cyst is a developmental odontogenic cyst which usually occurs in the second and third decade of life. Dentigerous cyst is one of the most prevalent types of odontogenic cysts associated with partially erupted, developing, or impacted teeth. The mandibular third molars have a high predictability followed by maxillary canines. Occurrence of dentigerous cyst bilaterally is generall...

The nasopalatine duct cyst (NPDC) is the most common of the non-odontogenic cyst of the jaws. This cysts are usually central or unilateral with no prevalence of side occurrence. The NPDC is the most frequent developmental, nonodontogenic cyst of the jaws. This cyst originates from epithelial remnants from the nasopalatine duct. The cells could be activated spontaneously during life, or are even...

AIM To report a case of a non-neoplastic variant of calcifying odontogenic cyst (COC) with the lining epithelium showing ameloblastomatous proliferation and capsule exhibiting features of a cholesterol granuloma. The importance of delineating this histologic variant from unicystic ameloblastoma and the formation of cholesterol granuloma in this variant is discussed. BACKGROUND Calcifying odon...

Abstract A simple bone cyst is described as an intra-osseous pseudocyst, devoid of epithelial lining and either empty filled with serous or sanguineous fluid. This case presents a rare example the ascending ramus mandible in paediatric patient. Studies have shown that less than 5% cysts jaw bones are located within mandibular ramus, most common site being premolar-molar region (75%). The 14-yea...

This study evaluated 1) the efficacy of packing autologous fat grafts around temporomandibular joint (TMJ) total joint prosthetic reconstructions to prevent fibrosis and heterotopic bone formation and 2) the effects on postsurgical joint mobility and jaw function. One hundred fifteen patients (5 males and 110 females) underwent TMJ reconstruction with total joint prostheses and simultaneous fat...

BACKGROUND AND OBJECTIVE: Calcifying odontogenic cyst is an uncommon developmental cyst. It accounts for only 1% of jaw cysts and uncommonly occurs with odontoma. Herein, we report a case of calcifying odontogenic cyst, associated with complex odontoma. CASE REPORT: The patient was a 12-year-old girl with complaints of painless swelling in the mandibular first premolar. In radiographic examinat...

Glandular odontogenic cyst (GOC) is an uncommon developmental cyst. It accounts for 0.012% to 1.3% of all the jaw cysts; its prevalence is 0.17%. It was described by Gardner et al. in 1988 as a distinct entity. GOC has a slight predilection for mandible and affect more commonly in the middle-aged patients. Radiographic and clinical features of this cyst are not pathognomonic or specific. Only t...

Gorlin's syndrome, also known as multiple basal cell naevi syndrome, is a well documented disorder of unknown etiology. Very often it is familial of autosomal dominant mode of transmission. It can affect any age group of both sexes. rt presents a wide spectrum of signs and symptoms involving nearly every system of the body. Classically it consists of triad features of multiple basal cell naevi,...
