Resin composite aggregated S-PRG particles are not superior to non-S-PRG under microcosm biofilm.

This study assessed the effect of composite resins, aggregated or not with S-PRG particles, and the use of toothpaste in controlling demineralization and bacterial growth. Human molars were distributed into 3 groups: control (CT) - sound teeth, Beautifil Bulk Restorative System (aggregated with S-PRG) (BB), Filtek One Bulk Fill (without S-PRG) (FB). Teeth destined for groups BB and FB previously received Class I preparations (4 × 4 × 4 mm), followed by single-increment restorations.

Characterization of Candida species isolated from the hands of the healthcare workers in the neonatal intensive care unit.

Colonization of health professional hands by potentially pathogenic microorganisms capable to expressing virulence factors, such as Candida spp., is worrisome because of the high contact between patients and professionals. The study aims to evaluate, in vitro, the following virulence factors: hemolytic activity, DNAse expression, biofilm formation, and susceptibility for antifungal agents of Candida species isolated from health professionals hands of a neonatal intensive care unit (NICU).
