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

January 24, 2026 updated by: Ghada Adayil, Cairo University

Diagnostic Agreement Between Visual Clinical Assessment and CBCT-Derived Palatal Angle Measurements for Determination of Palatal Arch Shape: Cross-Sectional Radiographic Study

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.
