Biofilms form rapidly on dental unit waterlines. The specific design of dental units favors bacteria to colonize surfaces and to form biofilm in water supply tubes, including dental unit water line (DUWL). The majority of the organisms in the biofilm are harmless environmental species, but some dental units may harbour opportunistic respiratory pathogens. Microbiological control of dental unit ...

Background:
 Dental impressions become contaminated with micro-organism from patient’s saliva and blood which can cross-infect stone cast poured against them. The aim of the present study was to compare efficacy commercially available disinfection products, one containing glutaraldehyde, sodium hypo chloride ethanol for material.
 Methods: For this investigations, dental impression 60...

THE OBJECTIVE The objective of this work is to prove that oral cavity fluids diffuse into alginate mass of impressions. In addition, the information is presented on the subject that disinfectants used for alginate impressions disinfection not only diffuse into alginate mass but penetrate deeper than oral cavity fluids. MATERIALS AND METHODS OF THE STUDY Three examination groups were formed fo...

CONTEXT Cross infection remains one of the major challenges in the dental profession, especially in field settings. Transmission of hepatitis B, hepatitis C, and human immunodeficiency virus have raised a major concern for patients and dental staff. These risks can be eliminated by effective sterilization and disinfection techniques. AIM The aim was to compare the disinfecting efficacy of thr...

The degree of success in the elimination of bacteria during cavity preparation and prior to the insertion of a restoration may increase the longevity of the restoration and therefore the success of the restorative procedure. The complete eradication of bacteria in a caries-affected tooth, during cavity preparation, is considered a difficult clinical task. In addition to weakening the tooth stru...

BACKGROUND Most of the materials (casts, impressions, etc.) that are sent to the dental laboratories show the presence of numerous pathogenic microorganisms. All the spray disinfectants are not equally effective against these microorganisms. AIMS AND OBJECTIVES The aim was to compare the effectiveness of different spray disinfectants on irreversible hydrocolloid impressions and to find out th...
