It is sometimes called White Spot Lesions, Initial Caries or Incipient Caries . If the process is not halted, the enamel surface nay brake, resulting in a Cavity . It is covered by plaque, which consists mainly of bacteria. When sugar consumption has ceased, saliva can wash away sugars and buffer the acids. Calcium and Phosphates can again enter the tooth.
Red sector represents bacteria, the dental plaque on the teeth.
Light blue sector represents susceptibility to disease. The Red sector decreases if there is a good oral hygiene and if there is a low proportion of cariogenic bacteria in the plaque. The Blue sector increases if there is a high and frequent intake of sugar and other easily fermentable carbohydrates. The Blue sector decreases if there is a low and infrequent intake of sugar and other easily fermentable carbohydrates. The Light blue sector increases if susceptibility is high, for example due to low exposure to fluorides, low saliva secretion, low buffering capacity of saliva.
