Minimally Invasive Techniques for Remineralization
Although the reduction of fermentable carbohydrate intake and the incorporation of fluoride in toothpaste and community water systems have been the mainstay of dental caries prevention, recent data confirm that dental caries remains a serious worldwide public health problem. The American Dental Association has long encouraged the implementation of minimally invasive approaches to treat incipient and white spot lesions. To support clinicians in their practice, clinical practice guidelines for the treatment of these lesions have been developed and are easily accessible. These guidelines include fluoride and nonfluoride caries preventive agents, available in different formulations, for professional and at-home use.
The Global Burden of Disease—a collaboration of more than 1,800 researchers from 127 countries—reported that what percentage of the world population experiences dental decay?
Which of the following may result due to dental caries?
Demineralization of enamel occurs when salivary pH drops below which level?
People with lower socioeconomic status experience the lowest prevalence and pathogenicity of dental caries.
The strength of enamel, the most mineralized tissue in the body, is conferred by hydroxyapatite crystals, which are composed of calcium and phosphate ions.
Remineralization of enamel is wholly dependent on re-incorporation of the lost calcium and phosphate back into the crystallite structure.
The presence of fluoride during the remineralization process creates a new structure called fluorohydroxyapatite, which is stronger and more resistant to decay than hydroxyapatite.
Aciduric and acidogenic bacteria (bacteria that generate and thrive in acidic environments) force salivary pH to increase.
In the oral cavity, probiotic intake resulted in significant increases in salivary pH, a process which is seen by many as crucial to remineralization.
Calcium and phosphate are essential for remineralization.
