Lateral periodontal cysts (LPCs) are odontogenic epithelial cysts composed of nonkeratinized epithelial cells that are in the category of developmental cysts, rather than inflammatory cysts. Lateral periodontal cysts are rare in both people and domestic animals; they are associated with vital teeth and located lateral to a tooth root. Lateral periodontal cysts are typically asymptomatic lesions that are characterized radiographically as a unilocular lucency with well-defined corticated borders. Canine acanthomatous ameloblastoma (CAA) is the most common odontogenic neoplasm in dogs and rarely presents as a cystic lesion...

Glandular odontogenic cyst (GOC) associated with ameloblastoma is an exceedingly rare histologic presentation with no known clinical significance or treatment applications. Four cases have been reported, three in the mandible and one in the maxilla. The age range is 14-65 and with male predilection. All four presented with swellings and two with pain. We add one more case to the literature of a 58-year old male presenting with an expansile multilocular radiolucency between teeth #19-23. The ameloblastomatous changes in this case are consistent with those of a unicystic ameloblastoma-mural subtype...

BACKGROUND: Ameloblastoma is a benign slow growing tumor of odontogenic origin composed of epithelial cells that resemble enamel forming cells namely the ameloblasts however these lesional cells do not differentiate to produce enamel. They are locally aggressive and can cause severe abnormalities of the face and jaw. AIM: This study aimed to correlate the incidence and recurrence rates of ameloblastoma to the different clinical and histopathological parameters. METHODS: A study on ameloblastomas in the Goan population for 16 years (1999-2014) was carried out...

Descending necrotizing mediastinitis (DNM) is a life-threatening disease which often develops from a purulent infection of the oral cavity and is associated with high rates of mortality. Here we report the case of a young patient who died from an aortic arch rupture in context of DNM developed from an odontogenic infection caused by Prevotella buccae. Based on the current knowledge on this very rare vascular complication, we discuss factors that may have contributed to this fatal issue and future issues to optimize care provided to patients...

AIMS AND OBJECTIVES: A keratocystic odontogenic tumour (KCOT) is a benign uni- or multicystic, intraosseous tumour of odontogenic origin, with a characteristic lining of parakeratinized stratified squamous epithelium and potential for aggressive, infiltrative behaviour. Various studies in hamsters showed that, alpha-Tocopherol, which is an active biological form of Vitamin E, is a potent antioxidant known to inhibit tumour formation and also regression of established tumours. So, the aim of the present pilot study was to assess the levels of Alpha-Tocopherol(Vitamin E) in Patients with KCOT and compare them with Vitamin E levels in normal healthy individuals...

Odontogenic tumours are a group of heterogeneous diseases that range from hamartomatous or non-neoplastic tissue proliferations to benign neoplasms to malignant tumours with metastatic potential. They are rare, comprising about <2-3% of all oral and maxillofacial biopsy specimens. The aim of the present study was to determine the clinico-pathological presentation of this heterogeneous group of lesions and review of literature. The present study was conducted in the ENT department of a Government Medical College and Hospital, West Bengal, India, over the period of 5 years from January 2011 to December 2015...

Previous studies show that both activin and Bmp4 act as crucial mesenchymal odontogenic signals during early tooth development. Remarkably, mice lacking activin-βA ( Inhba(-/-)) and mice with neural crest-specific inactivation of Bmp4 ( Bmp4(ncko/ncko)) both exhibit bud-stage developmental arrest of the mandibular molar tooth germs while their maxillary molar tooth germs completed morphogenesis. In this study, we found that, whereas expression of Inhba and Bmp4 in the developing tooth mesenchyme is independent of each other, Bmp4(ncko/ncko)Inhba(-/-) compound mutant mice exhibit early developmental arrest of all tooth germs...
