High-touch surfaces disinfection compliance in a COVID-19 intensive care unit.

Environmental cleaning and disinfection are fundamental health care-associated infection prevention measures. This study aimed to evaluate the disinfection compliance of high-touch surfaces in a COVID-19-only intensive care unit, using a fluorescent marker. It was divided into 3 phases, baseline assessment, educational feedback, and post feedback.

Protection of calcium silicate/sodium phosphate/fluoride toothpaste with serum on enamel and dentin erosive wear.

Objective: To evaluate the effect of a toothpaste containing calcium silicate/sodium phosphate/fluoride associated or not to the boost serum (BS) against erosive tooth wear (ETW) on enamel and dentin.

Methodology: Bovine enamel and dentin specimens were subjected to an erosion-abrasion cycling model (1% citric acid - pH 3.6 -2 min / artificial saliva - 60 min, 4×/day, 5 days).
