Odontogenic cysts and tumors originate from remnants of odontogenic epithelium and have a wide spectrum of histopathologic and clinical characteristics, ranging from benign non-invasive to locally invasive or malignant lesions. Histopathologic similarities between these lesions may challenge the correct diagnosis, especially in small size specimens, and may also lead to unnecessary broad surger...

Orthokeratinized odontogenic cyst (OOC) was initially defined as the uncommon orthokeratinized type of keratocyst (OKC) by World Health Organization (WHO). Several studies have shown that OOC has different clinicopathologic aspects when compared with other developmental cysts, especially OKC. So now emerges to be a distinct entity, according 4th edition WHO Classification Head and Neck Tumors w...

Odontogenic cysts, which showed cystic radiolucency in the jaw bone by radiographic examination and computed tomography, were enucleated by operation in 3 dogs. One dog had a odontogenic keratocyst in the incisive bone of the right maxilla and another 2 cases revealed dentigerous cysts in the mandible. These cyst walls were enucleated or transpired by semiconductor laser. Afterwards, osteogenes...

The aim of this study was to analyze the files of 695 consecutive patients operated on under general anesthesia for odontogenic cysts in an adult French teaching hospital for comparison with findings in world surveys. A retrospective survey of cysts of the jaws was undertaken at the Maxillofacial department, Pitié-Salpêtrière University Hospital, Paris, France. Data were retrieved from case not...

Odontogenic cysts originate from remnants of the tooth forming epithelium in the jaws and gingiva. There are various kinds of such cysts with different biological behaviours that carry different patient risks and require different treatment plans. Types of odontogenic cysts can be distinguished by the properties of their epithelial layers in H&E stained samples. Herein we detail a set of image ...

BACKGROUND the objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. MATERIAL AND METHODS Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. RESULTS A tot...

BACKGROUND Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and th...

OBJECTIVES The aim of the present study was to analyze the expression levels of Cyclin D1 (CCD1), a nuclear protein that plays a crucial role in cell cycle progression, in a series of keratin-producing odontogenic cysts. STUDY DESIGN A total of 58 keratin-producing odontogenic cysts, diagnosed over ten years and classified according to the WHO 2005 criteria, were immunohistochemically analyze...
