BACKGROUND AND AIMS Dental handpiece is a source of contamination because it is in constant touch with the oral cavity. Sterilization does not seem to be sufficient to prevent penetration of microorganisms into air and water lines of the unit, because negative pressure developed by valves (which are placed in water outlets) and post shut-off inertial rotation of handpiece result in water and de...

Aerosols generated in dental operations are a source of exposure to microorganisms proliferated within dental unit waterlines (DUWL) biofilm. It has been suggested that presence of Legionella species in these aerosols may contribute to potential health hazards for dental staff and patients. The article attempts to provide a brief overview of the current knowledge about Legionella, its prevalenc...

The effects of two ultrasonic cleaning units on surface deterioration and cleaning effectiveness of dental burs were compared in this study. The units tested were the Dextrex Model L 503B (Dextrex Chemical Industries, Inc., Bowling Green, KY) industrial ultrasonic unit and a conventional dental ultrasonic unit L & R T-21 B (L & R Manufacturing Co., Kearny, NJ). SEM photomicrographs of the burs ...

Background and Aim: Bacterial contamination of clinical surfaces of dental units that have been touched or been exposed to patients’ blood or saliva can be a reservoir for infections, leading to cross-contamination. This study aimed to evaluate bacterial contamination in the clinical environment of Sari Dental School in 2018. Materials and Methods: In this cross-sectional (descriptive-analytic...

BACKGROUND The authors aimed to determine whether electrical dental devices would interfere with the function of cardiac pacemakers or implantable cardioverter defibrillators (ICDs) in humans. METHODS The authors exposed asymptomatic nonpacemaker-dependent patients to commonly used electrical dental equipment (for example, battery-operated curing lights, ultrasonic baths, ultrasonic scalers, ...
