Biofilm maturation is the third stage in process of biofilm formation. A mature biofilm is a heterogenous slimy multilayered cells embedded in an extracellular polymeric substance composed of polysaccharide (45-95%), proteins (1-60%), nucleic acids (1-10%), lipids (1-40%) and water channels.
During biofilm development (Fig. 41.1) the primary colonizers (pioneer species) attach first and as the conditions in the biofilm change secondary colonizers are able to attach to the already established organisms, finally resulting in a stable, climax community.This colonization sequence has been extensively studied in dental plaque and different genera are continuously being added into an.
Biofilm. A biofilm is defined as a community of microorganisms attached to an inert or living surface by a self-produced polymeric matrix or an assemblage of microbial cells associated with a surface and enclosed in a matrix of primarily polysaccharide material.. but it does not provide quantitative data for statistical analysis.

Biofilms are increasingly being recognised as the preferred mode of growth of microbes in a wide range of habitats. Biofilms have a large and varied role in human activities from being responsible for a number of diseases in humans and animals to also being invaluable in the treatment of domestic sewage and industrial wastes.
This chapter gives an overview of microscopic methods for biofilm bacterial community analysis and mainly focuses on recent advancements in microscopic methods for the assessment of extracellular polymeric substances (EPS) that form a key component of the biofilm matrix.
Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth.It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow.It is commonly found between the teeth, on the front of teeth, behind teeth, on chewing surfaces, along the gumline, or below the gumline cervical margins. Dental plaque is also known as microbial plaque.
Through evidence-based webcasts, journal supplements, and peer-reviewed articles, this first-in-class resource center will be designed to encompass the current concepts in biofilm formation, its implications in human health and disease, and potential solutions to disrupt the formation of biofilm. 1 Jamal M, et al.
