FGFR1 is an important prognostic factor in oral leukoplakia and tongue squamous cell carcinoma.

Background: Fibroblast growth factor receptor 1 is a potential prognostic factor for tongue squamous cell carcinoma and is associated with oral epithelial dysplasia grade in oral leukoplakia.

Methods: Thirty cases of tongue squamous cell carcinoma and 30 cases of oral leukoplakia were analyzed. Fibroblast growth factor receptor 1 and phosphorylated Akt protein expression were analyzed by immunohistochemistry and quantified using a digital algorithm.

Dental Students' Perceptions and Performance in Use of Conventional and Virtual Microscopy in Oral Pathology.

Virtual microscopy (VM) is a technology for showing microscope slides using computers and could be considered a progression of classic methodology using optical microscopes. The aim of this study was to analyze the perceptions and performance of dental students in oral pathology regarding the use of conventional microscopy (CM) and VM in relation to teaching and learning. All fourth-semester dental students (N=165) in an oral pathology course at the Universidade Federal de Pernambuco in Brazil in 2016-17 were invited to participate in the study.
