INTRODUÇÃO: O odontoma é o tumor odontogênico mais comum, sendo considerado também como hamartoma. Sua classificação é baseada na morfologia apresentada, podendo ser classificado como composto, quando apresenta múltiplos dentículos, ou complexo, no caso de uma massa disforme. São geralmente diagnosticados em exames radiográficos de rotina e associados ao atraso no irrompimento dentário. OBJETIVO: Revisar a literatura acerca desse tipo de tumor odontogênico, bem como relatar o caso clínico de um paciente portador de odontoma complexo de grandes proporções envolvendo a região de ramo mandibular.

These results suggest the feasibility of using a generic violet light source as a low-cost alternative for fluorescence-guided surgery.

Carcinomas of salivary glands are rare and can affect major or minor salivary glands. Among them, the mucoepidermoid carcinoma is the most prevalent and its occurrence in the first 2 decades of life is highly unusual. Their common clinical aspect to different diseases is a challenge in diagnosis. The objective of this work is to elucidate the diagnosis of lesion in the hard palate of an adolescent patient, brown-skinned, male, forwarded to the oral surgery department at the State University of Londrina. Initially, he complained about a progressive swelling in the last 60 days. Through computed tomography scan, it was noted intraosseous involvement in the maxilla involving dental apex of the elements 13, 14, 15, right maxillary sinus extending to piriform sinus. Proceeding with clinical examination, followed by biopsy, histology, and immunohistochemical analysis, we established the diagnosis of mucoepidermoid carcinoma. After verification, the patient was sent to the referenced service to start cancer treatment.

Infection by severe respiratory syndrome coronavirus 2 (coronavirus disease 2019) has been the most important public health event of the last 100 years. The number of cases and deaths caused by this disease, its potential to rapidly spread and the search for a vaccine have been the center of discussion all over the world for over 1 year. In addition to the number of cases and all social, economic, and public health consequences of the pandemic, the variety of symptoms and clinical signs presented by infected patients has been subject of several studies and case reports. At the time of this writing, even with promising research, the clinical outcome of some patients is still unpredictable. The purpose of this article is to report an unusual case, the diagnostic process, and early treatment of this severe and atypical clinical picture. The patient is a young man diagnosed with coronavirus disease 2019 who sought our hospital in Southern Brazil reporting a history of pansinusitis progressing to a severe orbital cellulitis, requiring immediate surgical intervention.
