Background . Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth. This study correlated surface roughness to biofilm development with four commercially available ceramic materials. Methods . Four ceramic materials (Vita Enamic®, Lava™ Ultimate, Vitablocs Mark .
The bacterial counts indied biofilm formation on both surfaces at 7 and 28 ºC after 3 days. A number of viable cells, from 57 log cfu/cm 2 (10 5 to 10 7 cfu/cm 2), is required for biofilm formation, and lower values could indie an adhesion process (Ronner and Wong, 1993; Wirtanen et al., 1995). The highest intensity of biofilm formation on the stainless steel and polypropylene surfaces ...
· Staphylococcal adhesion and biofilm development were influenced by surface texture of polyurethane, as increased bacterial adhesion and larger bacterial aggregates were observed on the roughest patterned surfaces. Larger amounts of biofilm were found on the disks grinded with 320 grit paper compared to the disks grinded with 4000 grit paper. Biofilms after .
Microbes formed biofilm on the untextured specimen but, the square textured surface showed no apparent biofilm formation, while the biofilm was found in triangular textured surface as seen under the fluorescence and scanning electron microscope. The biofilm biomass was significantly reduced in the square textured surface. This work showed that laser textured surfaces might be potentially used ...
· Introduction. A biofilm is a population of microbial cells growing on a surface and enclosed in an amorphous extracellular matrix (Donlan 2002).Biofilm formed in food processing environments is of special importance as it has the potential to act as the chronic source of microbial contamination that may lead to food spoilage or transmission of diseases.
Biofilm formation is a natural phenomenon which occurs wherever there are microorganisms and surfaces – whether only slightly wet or immersed, and whether surrounded by a high or a low level of nutrients (even the low concentration of nutrients in ultrapure water is sufficient to support biofilm formation). This explains why biofilms are easy to produce in laboratory conditions, .
A biofilm is an assemblage of surfaceassociated microbial cells that is enclosed in an extracellular polymeric substance matrix. Van Leeuwenhoek, using his simple microscopes, first observed microorganisms on tooth surfaces and can be credited with the discovery of microbial biofilms. Heukelekian and Heller (1) observed the "bottle effect" for marine microorganisms, .

· Emerging research shows traditional disinfectants may not be able to wipe out antibioticresistant organisms. On any given day, one in 18 patients in a European hospital has a healthcareassociated infection research, looking at why some outbreaks seem impossible to resolve, shows that dry surface biofilms are present on up to 95% of .
