The study aimed to investigate oral potentially malignant disorders (OPMDs) diagnosed in an Oral Pathology service in southern Brazil over a span of 56 years and to assess the factors influencing their severity and outcomes. A retrospective analysis of histopathological records from 1965 to 2021 was performed. Lesions diagnosed as leukoplakia, erythroplakia, leukoerythroplakia, or actinic cheilitis were included.

Consequently, they are expected to possess the knowledge and the capability to recognize the features of this disease. The objective of the study is to evaluate dentists from different regions of Brazil regarding their level of knowledge and self-confidence regarding oral cancer.

- - The study investigated the perceptions of 192 dentists in Rio Grande do Sul about their training and practices related to diagnosing and preventing oral cancer, including their attitudes towards performing biopsies.
- - Results showed that while nearly all dentists perform thorough mouth exams and provide tobacco cessation counseling, only a small fraction regularly perform biopsies, mostly due to a lack of experience.
- - Many dentists felt that their clinical and theoretical training in oral medicine was inadequate, indicating a need for ongoing education and practical training to improve their skills in diagnosing oral lesions and cancer prevention.
Calcifying epithelial odontogenic tumor (CEOT), or Pindborg tumor, is infrequent and accounts for less than 1% of all odontogenic tumors. It is benign and usually asymptomatic but displays locally infiltrative and expansile behavior. Synchronous lesions affecting the jaws are exceedingly rare.

Materials And Methods: A retrospective study was conducted on 108,304 biopsies obtained from 1953 to 2016 at six Brazilian oral and maxillofacial pathology services. Demographic data and clinical and histopathological diagnosis of oral paracoccidioidomycosis were evaluated.
Location of injected polymethylmethacrylate microspheres influences the onset of late adverse effects: an experimental and histopathologic study.

Polymethylmethacrylate (PMMA) has been widely used in the correction of wrinkles because of its long-lasting cosmetic improvements. However, side effects and complications may occur, and its clinical appearance on the oral mucosa can be similar to that of inflammatory or neoplastic disease. The aim of this research was to compare the clinical and histopathologic responses to PMMA injected by two different methods.
View Article and Find Full Text PDFTufted angioma (TA) is a benign vascular tumor with endothelial origin. It is extremely rare in oral mucosa; only seven cases have been reported in the literature so far. Here, we describe two cases of tufted angioma observed in children and we also present a review of the literature about this pathology, concerning the differential diagnosis and management of this lesion in children.

Study Design: The sample comprised 10 cases of normal oral epithelium, 10 cases of hyperkeratosis, 10 cases of acanthosis, 10 cases of hyperkeratosis with acanthosis and 10 cases of epithelial dysplasia. The mean number of AgNORs per nucleus (mAgNOR) and the mean percentage of cells with 1, 2, 3 and 4 or more AgNORs per nucleus (pAgNOR) were recorded.
