Current concepts of Caries The disease process begins with the concentration of mutans streptococcus at specified tooth surfaces and may lead to white spot formation or even cavitation 6

Current concepts of Caries The development of dental caries is a dynamic process of demineralization of the dental hard tissues by the products of bacterial metabolism, alternating with periods of remineralization Harris and christen 《 Primary Preventive Dentistry》,1995
