What factors determine caries risk?

CAMBRA assesses disease indicators (current cavities, white spots), risk factors (frequent sugar intake, dry mouth, deep pits), and protective factors (fluoride use, sealants, saliva flow).

What score indicates high caries risk?

Any presence of a disease indicator (active cavities, white spots, visible plaque) automatically elevates risk to high regardless of other factors.

How often should high-risk patients be seen?

High-risk patients typically need recall visits every 3 months, fluoride varnish applications, and chlorhexidine rinse therapy.

Formula Definitions

The Caries Risk Assessment Calculator — CAMBRA Score works by applying a well-defined formula to the values you enter. Understanding the formula behind the calculation helps you interpret the result and check that your inputs are correct. Below we break down the key components that drive the Caries Risk Score.

The core formula used by this calculator is:

Result = f(patient inputs, clinical reference)

Each variable in the formula has a specific meaning:

patient inputs — Age, weight, height, lab values, vitals, or clinical findings entered into the Caries Risk Score.
clinical reference — Reference range, scoring system, or population standard the result is compared against.
Result — Computed clinical score, risk estimate, or diagnostic value.

Note: Clinical results are decision-support only and must be interpreted by a qualified clinician.

How to Use This Calculator

Enter patient clinical data. Enter the patient's age, weight, lab values, vitals, or clinical findings into the Caries Risk Assessment Calculator — CAMBRA Score input fields.

Select the clinical scoring system. Select or confirm the appropriate clinical scoring system or reference range for the patient population.

Calculate the clinical score. Press Calculate to compute the clinical score, risk estimate, or diagnostic result.

Interpret the result. Review the output against the provided reference ranges, risk categories, or guideline thresholds. Consult a qualified clinician before acting on results.

Glossary and Definitions

Clinical score

A numeric value derived from patient inputs that estimates risk, severity, or diagnostic likelihood for a given condition.

Reference range

The set of values considered normal for a healthy population, used to interpret a calculated result.

Sensitivity

The probability that a positive result correctly identifies a patient with the condition.

Specificity

The probability that a negative result correctly identifies a patient without the condition.
