Unlike other parts of the body, tooth surfaces are uniquely hard and non shedding. Therefore, the warm and moist environment of the mouth and the presence of teeth, makes a good environment for growth and development of dental plaque. [12] The main ecological factors that contribute to plaque formation are pH, saliva, temperature and redox ...
The dental pellicle, or acquired pellicle, is a protein film that forms on the surface enamel, dentin, artificial crowns, and bridges by selective binding of glycoproteins from saliva that prevents continuous deposition of salivary calcium phosphate. It forms in seconds after a tooth is cleaned, or after chewing.
Surface roughness can also affect biofilm adhesion. Rough, high-energy surfaces are more conducive to biofilm formation and maturation, while smooth surfaces are less susceptible to biofilm adhesion. The roughness of a surface can affect the hydrophobicity or hydrophilicity of the contacting substance, which in turn affects its ability to adhere.
Gingivitis is a non-destructive disease that causes inflammation of the gums; [1] ulitis is an alternative term. [2] The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that are attached to tooth surfaces, termed plaque-induced gingivitis.
By doing this, the clinicians visibility of the tooth is greatly improved, due to the increase in contrast with the rubber dam around the tooth or teeth, whilst at the same time it retracts the soft tissues such as the lips, tongue, and cheeks, and reduces mirror fogging:allowing the clinician to focus solely on the restorative site, which can ...
Another protective function throughout the cardiovascular system is its ability to affect the filtration of interstitial fluid from capillaries into the interstitial space. [7] The glycocalyx, which is located on the apical surface of endothelial cells, is composed of a negatively charged network of proteoglycans, glycoproteins, and glycolipids ...
Heavy staining and calculus deposits exhibited on the lingual surface of the mandibular anterior teeth, along the gumline Calculus deposit (indicated with a red arrow) on x-ray image In dentistry , calculus or tartar is a form of hardened dental plaque .
The low-pH environment in the biofilm matrix erodes the surface of the teeth and begins the "initiation" of the dental caries. [19] Streptococcus mutans is a bacterium which is prevalent within the oral environment [ 22 ] and is thought to be a vital microorganism that contributes to this initiation. [ 23 ]
