RESUMEN
A high-speed handpiece is used in several dental procedures and the official recommendation for safe decontamination consists of rinsing with water, washing with detergent, mechanical friction, and sterilization; however, many professionals only apply 70% w/v alcohol without also cleaning the tool between patients. We performed an analysis of high-speed handpieces reprocessed only with 70% w/v alcohol and found that the methods used in clinical practice are not safe.

Vancomycin susceptibility was determined in 125 S. aureus isolates by disk diffusion, microdilution, Etest and vancomycin brain heart infusion (BHI) plate. A 2.0 mg/L vancomycin BHI was highly sensitive (100% and 91% compared to Etest and microdilution) for detecting a MIC≥2 mg/L, and could be used as a simple and affordable screening test.
