Background: Fear of dental care prevents dental cleaning behavior and increases the prevalence of dental caries. This study was conducted to determine the effect of Trans-Theoretical Model constructs and fear of dental care on the dental cleaning behavior of students. <span style="font-family...

Reprocessing comprises three steps: cleaning, disinfection and-if required-sterilisation. While the extents of disinfection and of sterilisation are quantitatively defined, there are only imprecise (qualitative) definitions of cleaning. There are two main reasons for accurate cleaning. First organic and inorganic materials that remain on inner and outer surfaces will interfere with the efficacy...

OBJECTIVE Studies have demonstrated frequent contamination of stethoscope and usefulness of different disinfectants. Albeit, studies on the precise mode of cleaning and frequency of cleaning are lacking. This study was carried out to determine efficacy of 66% ethyl alcohol as disinfectant, rate of recontamination without cleaning and benefits of daily versus immediate cleaning. METHODOLOGY Pr...

The purpose of this laboratory study was to assess the potential cleaning efficacy of nine different toothbrushes around brackets in vitro. Standard and Mini Diamond brackets were fixed on coloured teeth in a special model, coated with white titanium oxide, brushed in a machine with different manual toothbrushes (three different types: planar, staged, and v-shaped bristle field), and tested wit...

The application and efficacy of cleaning and disinfection methods are reviewed, together with the relevant European and French legislation. European Commission Hygiene Directive 93/43/EEC of 14 June 1993 proposes the adoption of hazard analysis and critical control points (HACCP) for the meat industry, and this includes cleaning and disinfection. It is necessary to organise a team for washing, ...

PURPOSE To evaluate the cleaning efficacy of a new electric toothbrush and new brush head design, using a robot system to simulate normal clinical toothbrush use. MATERIALS AND METHODS The study compared the new oscillating/rotating/pulsating electric toothbrush (Braun Oral-B 3D Plaque Remover) comprised of the D15 handle and new EB15 brush head, with the clinically established oscillating/ro...
