Diagnostic Agreement Between Clinical Assessment and CBCT Palatal Angle for Palatal Arch Shape

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.
