Remineralization
Remineralization is a term from dentistry and means the re-storage of destroyed or lost minerals of the tooth enamel after previous demineralization . Demineralization is the depletion of minerals, e.g. B. Loss of calcium from bones or teeth .
The process of demineralization and remineralization occurs several times a day in vivo . The dynamic balance between demineralization and remineralization determines the end result. This either leads to cavitation, to repair or to maintaining the status quo . The interplay between the surface of the tooth and the saliva plays a decisive role . The saliva is considered to be a solution saturated with calcium and phosphate ions. This supersaturation enables the reprecipitation of calcium and phosphate ions from the saliva into the surface layer, whereby carious initial lesions can be repaired. The presence of fluoride can promote remineralization in vitro .
