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.

Combined therapy using low level laser and chitosan-policaju hydrogel for wound healing.

We have evaluated the effect of POLI-CHI hydrogel based on policaju (POLI) from cashew tree (Anacardium occidentale L.) gum and chitosan (CHI), associated or not with Low level laser therapy (LLLT), in wound healing. Sixty male Wistar rats were assigned into four groups: POLI-CHI hydrogel (H); LLLT (L); POLI-CHI with LLLT (HL) and saline control (C).
