Caries Risk Assessment
Also written as: CRA — Caries Risk Assessment
A structured evaluation of biological, behavioral, and environmental factors to predict an individual's likelihood of developing dental caries.
Full Definition
Caries risk assessment (CRA) is a systematic process used in dental research and clinical practice to stratify patients into low, moderate, or high caries risk categories. Assessment tools incorporate factors such as past caries experience, salivary flow rate, fluoride exposure, dietary habits, and presence of cariogenic bacteria (principally Streptococcus mutans). In research documents, CRA tools (e.g., CAMBRA—Caries Management by Risk Assessment) should be identified by their full validated name on first mention. Editors should verify that risk categories are defined consistently throughout a manuscript and that any proprietary tool name is correctly styled.
Usage
Usage note: CRA should be distinguished from a caries activity test, which measures actual bacterial or acid activity rather than predictive risk factors.
