Digital Caries Risk Questionnaire: does it match CAMBRA in Egyptian adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a cross‑sectional study that compares a new digital questionnaire for caries risk (DCRQ) with the CAMBRA protocol. The study uses STARD 2015 and GRAPPA guidelines to evaluate diagnostic agreement. The Decayed, Missing, and Filled Teeth (DMFT) index (DMFT ≥ 4) serves as a reference outcome to help interpret construct validity, while CAMBRA is the primary comparator for risk classification. Adults aged 18–65 with at least 10 natural teeth and who are in Egypt for at least 5 years are eligible. The study is conducted at October University for Modern Sciences and Arts in Giza and Sixth of October City under the lead sponsor with no listed collaborators.
