E-learning as a strategy in dentistry in the context of COVID-19: a path to follow?

Abstract

The current study aims to assess the effectiveness of e-learning in compliance with the new biosafety recommendations in dentistry in the context of COVID-19 applied to the clinical staff of a dental school in Brazil. A quasi-experimental epidemiological study was carried out by means of a structured, pre-tested online questionnaire, applied before and after an educational intervention, using an e-learning format. After data collection, statistical tests were performed. A total of 549 members of the clinical staff participated in the study in the two collection phases, with a return rate of 26.9%.After the e-learning stage, a reduction was found in the reported use of disposable gloves, protective goggles, and surgical masks. The course had no impact on the staff's knowledge concerning the proper sequence for donning PPE and showed 100% effectiveness regarding proper PPE doffing sequence. Knowledge about avoiding procedures that generate aerosols in the clinical setting was improved. Despite the low rate of return, it can be concluded that online intervention alone was ineffective in significantly improving learning about the new clinical biosafety guidelines. Therefore, the use of hybrid teaching and repetitive training is highly recommended.

Proteomic Analysis of Human Saliva via Solid-Phase Microextraction Coupled with Liquid Chromatography–Mass Spectrometry

“…Due to the limited access to updated databases at the time of the project, this work stands as a proof-of-concept study demonstrating that matrix-compatible SPME devices with porous extraction phases are a viable option for peptide and protein analysis. The logistics of personal protective equipment (PPE) for frontline healthcare professionals has improved drastically since the pandemic, , enabling significant improvements to the reproducibility and reliability of sample collection under clinical settings. Variabilities accrued during the self-collection, transportation, storage, and treatment of biofluids can, therefore, be greatly reduced in future studies.…”
