Dental caries is a microbial disease of calcified tissues of tooth which is characterized by deminaralization of the inorganic parts and destruction of its organic structures.It is a complex, continuous, dynamic biological process of tooth decay, comprising of periods of rograssion alternating with periods of arrest or even partial repair.
