Tooth wear and sensitivity and their risk factors across U.S. dental school sites

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, multi-site epidemiological study enrolling roughly 2,500 healthy dentate adults across up to five U.S. dental school clinics to measure the prevalence of erosive tooth wear and dentin hypersensitivity. Participants will undergo oral examinations, intraoral scanning, and standardized data collection on possible risk factors, with enrollment balanced across age brackets and sexes. Secondary measures include gingival recession and non-carious cervical lesions, and images will be reviewed centrally for consistency. The U.S. results will also be compared with prior datasets from Europe and China to identify similarities and regional differences.
