Caries prevention and reversal based on the caries balance.

The science behind caries prevention and reversal is well understood. A recent clinical trial has confirmed that reducing caries risk results in a reduction in dental decay. Dental caries progression or reversal depends upon the balance between demineralization and remineralization and can be visualized for clinical purposes as the "caries balance." This balance is determined by the relative weights of the sums of pathological factors and protective factors. A structured caries risk assessment should be carried out based upon the concept of the caries balance. Following the risk assessment, a treatment plan is devised which leads to the control of dental caries for the patient. The balance between pathological and preventive factors can be swung in the direction of caries intervention and prevention by the active role of the dentist and his/her auxiliary staff.
