Biofilms are well-organized communities of cooperating microorganisms that can include bacteria, algae, fungi and diatoms. Dental unit waterlines (DUWL) are an integral part of dental surgery equipment, supplying water as a coolant, primarily for air turbine and ultrasonic scalers. Surveys of dental unit waterlines (DUWLs) indicate that biofilm formation is a universal problem and great majorit...

Good water quality, achieved with environmentally friendly means, is essential in ensuring the safe operation of a dental practice. Our aim was to evaluate procedures and protocols used by dentists for quality sustainability. Greek (n = 206) participated this questionnaire-based study. Statistically significant results (p < 0.05) have shown that (a) female were more interested additional inf...

Aim and Purpose Biofilms in dental unit waterlines (DUWLs) are extremely difficult to eliminate. Aim of this study is to evaluate the efficacy of a mixture of four D-amino acids on biofilm dispersion in DUWLs. Materials and Methods A mixture of four D-amino acids (D-methionine, D-tryptophan, D-leucine, and D-tyrosine, 10 mM each), distilled water (control), and 0.1 M hydrochloric acid (HCl) w...

Introduction. The risk for active tuberculosis (TB) infection among dental healthcare workers (DHCWs) is controversial. Specifically, TB incidence is generally low among general dental practitioners, but it is higher than in the general population among hospital/prison dentists, DHCWs who work in endemic areas, students during clinical training with direct patient contact. Aim. To investigate p...

the Centers for Disease Control and Prevention/ National Healthcare Safety Network, are primarily designed for surveillance purposes, and only patients with KPC-2-Kp bacteriuria who do not meet these criteria are thought to have urinary tract infection and receive treatment. The results presented here show that the outcomes of CRE bacteriuria/bacteremia are influenced by both the choice of anti...

This study was designed to examine the in vitro bactericidal activity of hydrogen peroxide against Legionella. We tested hydrogen peroxide (Peroxy Ag⁺) at 600 ppm to evaluate Legionella survival in a simulated dental treatment water system equipped with Water Hygienization Equipment (W.H.E.) device that was artificially contaminated. When Legionella pneumophila serogroup (sg) 1 was exposed to P...
