Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether a digital questionnaire can accurately assess a person's risk of developing cavities, compared to the standard clinical method (CAMBRA). About 384 Egyptian adults aged 18 to 65 will fill out the questionnaire and receive a clinical exam. The goal is to see if the digital tool can reliably classify risk levels, potentially making cavity prevention easier and more widespread.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Digital Caries Risk Questionnaire (DCRQ)
What this could lead to
If successful, this digital tool could make cavity risk assessment faster and more accessible, helping prevent tooth decay.
What could go wrong
This is a cross-sectional study, not a trial of treatment. The questionnaire may not accurately predict future cavities, and results may not apply outside Egypt.
