Dental caries is a dynamic process taking place in the microbial deposits Dental caries is a dynamic process taking place in the microbial deposits on the tooth surface. It results in a disturbance of the equilibrium between on the tooth surface. It results in a disturbance of the equilibrium between the tooth surface and the surrounding plaque fluid so that, over time, the the tooth surface and the surrounding plaque fluid so that, over time, the net results may be a loss of mineral from tooth surface in which carious net results may be a loss of mineral from tooth surface in which carious lesion can be occurred as a result of that processlesion can be occurred as a result of that process
