NCT07363200

Brief Summary

Standardized intraoral photographs corresponding to each CBCT scan will be evaluated by two calibrated examiners. Palatal arch shape will be visually classified into one of three categories: high arched palate, normal palate, or low/shallow palate. Examiners will perform assessments independently and will be blinded to CBCT measurements and to each other's results.
