Dental plaque
Dental plaque is a biofilm of microorganisms (mostly bacteria, but also fungi) 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 (supragingival), or below the gumline cervical margins (subgingival). Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm, and bacterial plaque biofilm. Bacterial plaque is one of the major causes for dental decay and gum disease. It has been observed that differences in the composition of dental plaque microbiota exist between men and women, particularly in the presence of periodontitis.
Progression and build-up of dental plaque can give rise to tooth decay, and periodontal problems. Hence it is important to disrupt the mass of bacteria and remove it. Tooth decay is the localized destruction of the tissues of the tooth by acid produced from the bacterial degradation of fermentable sugar. Common periodontal problems include gingivitis and periodontitis. Plaque control and removal can be achieved with correct daily or twice-daily tooth brushing and use of interdental aids such as dental floss and interdental brushes.
Oral hygiene is important as dental biofilms may become acidic causing demineralization of the teeth (also known as dental caries) or harden into dental calculus (also known as tartar). Calculus cannot be removed through tooth brushing or with interdental aids, but only through professional cleaning.
Dental plaque is a biofilm that attaches to tooth surfaces, restorations, and prosthetic appliances (including dentures and bridges) if it is left untreated. Understanding the formation, composition, and characteristics of plaque helps with controlling the build up. An acquired pellicle is a layer of saliva that is composed of mainly glycoproteins and forms shortly after cleaning of the teeth or exposure of new teeth. Bacteria then attach to the pellicle layer, form micro-colonies, and mature on the tooth. This will then result in oral diseases.
Different types of bacteria are normally present in the mouth. These bacteria, as well as leukocytes, neutrophils, macrophages, and lymphocytes, are part of the normal oral cavity and contribute to the individual's health. Approximately 80–90% of the weight of plaque is water. While 70% of the dry weight is bacteria, the remaining 30% consists of polysaccharides and glycoproteins.
The bulk of the microorganisms that form the biofilm are Streptococcus mutans and other anaerobes. However, the precise composition varies by location in the mouth. Examples of such anaerobes include fusobacterium and actinobacteria. S. mutans and other anaerobes are the initial colonizers of the tooth surface, and play a major role in the establishment of the early biofilm community. Streptococcus mutans uses the enzyme glucansucrase to convert sucrose into a sticky, extracellular, dextran-based polysaccharide that allows the bacteria to cohere, forming plaque. Sucrose is the only sugar that bacteria can use to form this sticky polysaccharide. These microorganisms all occur naturally in the oral cavity and are normally harmless. However, failure to remove plaque by regular tooth-brushing allows them to proliferate unchecked and build up in a thick layer, which can cause various dental diseases for the host. Those microorganisms nearest the tooth surface typically obtain energy by fermenting dietary sucrose, and during fermentation they begin to produce acids.
The bacterial equilibrium position varies at different stages of formation. Below is a summary of the bacteria that may be present during the phases of plaque maturation:
Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organized to a particular structure and function. Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognized using modern techniques.
