Objectives: To analyse the occurrence of calcifying epithelial odontogenic tumours (CEOT) based on biopsy records from different Brazilian geographic regions and to contrast the data with a review of the literature.
Materials And Methods: A 2-step study was conducted. Step 1 consisted of a collaborative study of biopsies obtained from 1953 to 2017 at six Brazilian oral and maxillofacial pathology centres.
Objectives: To investigate the frequency of calcifying odontogenic cysts (COCs) that have been submitted for microscopic examination from representative geographic regions of Brazil and to compare it with literature data.
Materials And Methods: A retrospective study was conducted on biopsies obtained from 1953 to 2016 at 10 Brazilian oral and maxillofacial pathology centres. A total of 198,350 biopsy specimens were analysed.
Objective: The aim of this study was to investigate the frequency and some characteristics of odontogenic tumours, odontogenic cysts and non-odontogenic cysts in an elderly population (≥60 years).
Background: Few studies describe the distribution of oral lesions in older people.
Materials And Methods: A retrospective descriptive cross-sectional study was performed.
Mucoepidermoid carcinoma (MEC) corresponds to 5-12% of all salivary gland tumours, and is classified as low, intermediate or high grade. Traditionally, immunohistochemistry was considered as the complementary tool for diagnosis of salivary gland neoplasia. Lectin histochemistry has also been increasingly used in recent years.

Materials And Methods: Forty Sprague Dawley rats had their right sciatic nerve crushed for 1 minute in a hemostatic tweezer. The animals were divided into experimental and control groups.
