Hello and welcome to dentalcare.com's cariology course. This section focuses on remineralization and demineralization. This is part five of a 10 part series entitled Caries Process and Prevention Strategies. Caries is a chemical dissolution of the hard two structures, enamel and dentin, by the acid created as the bacteria in dental plaque ferment carbohydrates. The development of caries is dependent on the interplay between processes that cause demineralization of tooth enamel and those which cause remineralization. Only when factors favor the high acidity that leads to demineralization, does caries occur.
In this course, the dynamic processes of demineralization and remineralization are discussed, paying particular attention to tooth hard tissue structure, the role of acid production by cariogenic bacteria and the critical pH that which tooth enamel beings to dissolve. The role of acid reducing bacteria, saliva and fluoride in tooth hard tissue remineralization will also be explained.
