Ellagic Acid-Cyclodextrin Complexes for the Treatment of Oral Candidiasis.

The increase in the prevalence of fungal infections worldwide and the rise in the occurrence of antifungal resistance suggest that new research to discover antifungal molecules is needed. The aim of this study was to evaluate the potential use of ellagic acid-cyclodextrin complexes (EA/HP-β-CD) for the treatment of oral candidiasis. First, the effect of EA/HP-β-CD on planktonic cells and biofilms was evaluated.

Oral prevalence and antifungal susceptibility of Candida species in cystic fibrosis patients.

Objective: This study aimed at assessing the oral prevalence ofCandida species in cystic fibrosis patients and the antifungal susceptibility of the isolates.

Design: One hundred patients aged 3-20 years old were included in the study and were divided into three groups: G1 (low severity disease): 25 cystic fibrosis patients with Shwachman-Kulczycki score (SK) between 100 and 71; G2 (high severity disease): 25 cystic fibrosis patients with SK score under 40; and G3 (control): 50 healthy patients age- and gender-matched to cystic fibrosis patients. Stimulated saliva samples were collected and the oral fungal concentrations were assessed.

Silver nanoparticles coated with dodecanethiol used as fillers in non-cytotoxic and antifungal PBAT surface based on nanocomposites.

In the present study, we report the preparation of antifungal and non-cytotoxic polymer nanocomposites with potential application in biomedical materials. Dodecanethiol-protected silver nanoparticles (AgNPs-DDT) were synthesized by a reduction/precipitation method and dispersed in chloroform to obtain stable colloidal dispersions. PBAT-based nanocomposites containing 0.

Enterococcus Species in the Oral Cavity: Prevalence, Virulence Factors and Antimicrobial Susceptibility.

Enterococci are considered as transient constituent components of the oral microbiome that may cause a variety of oral and systemic infections. As there is sparse data on the oral enterococcal prevalence, we evaluated the Enterococcus spp. and their virulence attributes including antimicrobial resistance in a healthy Brazilian cohort.

Coating dental implant abutment screws with diamondlike carbon doped with diamond nanoparticles: the effect on maintaining torque after mechanical cycling.

Purpose: To determine the effect of maintaining torque after mechanical cycling of abutment screws that are coated with diamondlike carbon and coated with diamondlike carbon doped with diamond nanoparticles, with external and internal hex connections.

Materials And Methods: Sixty implants were divided into six groups according to the type of connection (external or internal hex) and the type of abutment screw (uncoated, coated with diamondlike carbon, and coated with diamondlike carbon doped with diamond nanoparticles). The implants were inserted into polyurethane resin and crowns of nickel chrome were cemented on the implants.
