Dental plaque, SEM
Dental plaque, coloured scanning electron micrograph (SEM). Plaque consists of a film of bacteria (red) embedded in a glycoprotein matrix. One of the bacteria in this sample is Fusobacterium nucleatum. The matrix is formed from bacterial secretions and saliva. Plaque is the main cause of tooth decay. The bacteria feed on sugars in food, producing acid as a waste product. This acid corrodes the teeths enamel coating, resulting in dental caries. A build-up of dental plaque can also lead to inflamed and infected gums. Severe gum disease can lead to teeth falling out

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate world of dental plaque under a scanning electron microscope. The image reveals a vivid display of red bacteria embedded within a glycoprotein matrix, with one particular bacterium identified as Fusobacterium nucleatum. This matrix is formed by bacterial secretions and saliva, creating the foundation for plaque formation. Dental plaque, although visually intriguing, serves as the primary culprit behind tooth decay. As the bacteria feed on sugars present in our food, they produce acid as a waste product. Over time, this corrosive acid erodes the protective enamel coating of our teeth, leading to dental caries or cavities. Moreover, an accumulation of dental plaque can also trigger inflammation and infection in our gums. If left untreated, severe gum disease may ensue and ultimately result in tooth loss. Through this remarkable photograph captured using false coloring techniques and advanced microscopy technology like SEM (scanning electron microscope), we gain insight into the microscopic world that impacts our oral health profoundly. Science Photo Library continues to provide invaluable visual resources that aid medical professionals and researchers in understanding various diseases and conditions affecting human health.
