Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this r...

The author experienced 8 cases of pericoronal radiolucency involving an incomplete tooth crown that had not developed to form the cemento-enamel junction, and the underdeveloped crown sometimes appeared to be floating within the radiolucency radiographically. The first impression was that these cystic lesions had odontogenic keratocysts, but half of them turned out to be dentigerous cysts histo...

Maxillary sinus harbours many pathological lesions. Many of those presents as a sinonasal mass and are rarely symptomatic. These masses are usually an antral polyp, mucoceles or mucous retention cysts. Odontogenic keratocyst, a benign odontogenic lesion presenting within the maxillary sinus is a rare entity. We present a case of odontogenic keratocyst of the maxillary sinus in a 35 years old fe...

Introduction: Odontogenic cysts are characterized by an expansile non–infiltrative growth through several mechanisms which include presence of mast cells in the capsule. The mast cells can be demonstrated histochemically as well as immunohistochemically. Aim and Objectives: The primary objective of the study was to analyze the presence and distribution of mast cells in radicular cyst, dentigero...

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...

The expression of cell adhesion molecule CD44s was analyzed immunohistochemically in 20 odontogenic lesions. CD44s was detected in almost all the cells on the cell membrane in basal and parabasal cells of the odontogenic cystic lining of the dentigerous cysts and the radicular cysts sparing the superficial layer of the cystic lining. CD44s was expressed on the cell membrane of the peripheral co...

conclusions the authors recommended to have paraclinical tests, especially vitality tests, in addition to clinical and radiographic examinations to avoid endodontic mistreatment. in suspicious cases, biopsy of lesions, referral to pathologist, and long-term fallow-up is required. context the essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. pe...

The cysts that originate in the remnants of dental lamina or enamel organ are known as odontogenic cysts. They are of great interest to otolaryngologists due to their proximity to the maxillary sinus and adjacent areas.1 Radicular cysts represent 72.5% of all odontogenic cysts, followed by dentigerous cysts (DC) (22.2%), and residual cysts (RC) (4.26%).2 The options for treatment of cystic lesi...

Odontogenic cyst is a common lesion that can happen after inflammation of the dental pulp. The therapeutic approach of these cysts is made at dentist's offices, and depending on their extension, they may develop oroantral fistula and chronic sinusitis. The objective of this study is to propose the videoendoscopic treatment of the odontogenic cyst with expression in the maxillary sinus. We made ...
