Caries risk assessment forms the cornerstone for the successful application of a minimum intervention dentistry philosophy in the management of dental caries. Patients, particularly those with evidence of active dental caries at baseline, require a caries risk assessment to identify those risk factors that will most likely contribute to the progression of the carious disease process. Once identified, these factors should be eliminated or at least moderated to ensure the disease progression is stabilized before conservative and rehabilitative dental procedures are undertaken. Each individual will present with a slightly different caries risk profile and the principles of a patient centred approach to manage each case should be applied to the individual diagnostic and treatment planning phases of dental care. Current chairside technologies such as caries susceptibility and activity tests can be utilized to provide baseline and follow-up data to assist the dental practitioner in this task. However, clinician intuition or 'gut feeling' has been found to be a better prognostic indicator for future dental caries experience than present caries prediction instruments in most cases. As caries risk data are accumulated and refined at a population, community and individual level, the sensitivity and specificity of the caries risk assessment modelling will improve as will the positive predictive power of the final statistical model algorithm. It is likely that online caries predictive tools will be available for general dental practitioners in the not too distant future to help clinicians formulate accurate caries risk profiles for their patients.
