BACKGROUND The aim of this study was to determinate the relative frequency of odontogenic tumors (OTs) in a Brazilian population and to compare this data with previous reports. METHODS We reviewed the achieves of 19 123 specimens from oral pathology laboratory of Universidade Federal de Minas Gerais, from 1954 to 2004. Using the criteria of histologic(More)
OBJECTIVE To determine the demographic profile of all histologically diagnosed odontogenic cysts (OC) and nonodontogenic cysts (nOC) over a 51-year period in the Brazilian population. STUDY DESIGN Case records of patients with OC and nOC from the files of the Oral Pathology Service, School of Dentistry, Federal University of Minas Gerais, Belo Horizonte,(More)
BACKGROUND Genetic factors are known to be involved in oral squamous cell carcinoma (OSCC) development. METHOD We evaluated a possible association between CCND1 A870G and P21/WAF1 C98A polymorphisms and OSCC, as well as the impact of the genotypes on protein immunoexpression. The study group consisted of 80 individuals with histopathological diagnosis of(More)
OBJECTIVE The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with ethanolamine oleate. STUDY DESIGN Twenty-seven patients with 30 examples of oral vascular malformation, hemangioma, or varix were treated with intralesional injections of 1.25% or 2.5% ethanolamine oleate at an interval of 15(More)
OBJECTIVE This study aimed to survey the demographic profile of supernumerary teeth (ST) in Brazilian children and adolescents. METHODS A retrospective analysis was carried out of all nonsyndromic patients with ST attended at the Pediatric Oral Surgery Service of the Universidade Federal de Minas Gerais between 1995 and 2004. Diagnosis of ST was based on(More)
Inflammatory myofibroblastic tumor is a rare lesion composed of myofibroblastic spindle cells accompanied by inflammatory infiltrate. The objective of this paper is to report an uncommon case of inflammatory myofibroblastic tumor located in the alveolar mucosa of the mandible. A 33-year-old male presented an asymptomatic tumoral lesion, firm, pedunculated,(More)
Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin´s lymphoma found in oral and maxillofacial regions. A large number of cases may be biologically heterogeneous, which are commonly defined as DLBCL, not otherwise specified (NOS) by the World Health Organization (WHO-2008). The present case reports on an ulcer of raised and(More)

BACKGROUND POF is well described in the literature, but this is the first report in a newborn. PATIENT A 4-month-old female newborn was referred to our department because of an exophytic, sessile,(More)
The aim of this paper was to assess the nonsurgical treatment of oral leukoplakia (OL). A medline search from 1983 to 2009 was conducted. The topical or systemic nonsurgical treatments or combination of both was reviewed. The primary outcomes of interest were clinical resolution, malignant transformation, follow-up, and recurrence of OL. Studies showed a(More)
The immunohistochemical expression of PCNA and Ki-67 proteins and the histochemical expression of AgNORs were studied in 20 odontogenic keratocysts in order to assess the relationship between epithelial cell proliferation and inflammation within the capsule. Immunostained cells were quantified by conventional methods, and both quantitative and morphometric(More)
