Demineralization of enamel remains an important health issue worldwide and occurs when the dynamic demineralization-remineralization balance in enamel is altered by acid-producing bacteria during fermentation of dietary sugars. This is a process which can be diagnosed and cured during the early stage. Therefore, the focus of modern dentistry has recently shifted to developing methods for early detection of carious lesions and non-invasive treatment options such as remineralization, in order to prevent disease progression and improve esthetics, strength, and function of the tooth. This book emphasis on various remineralizing agents that can safely and effectively promote organized mineral deposition onto dental tissues.
