The primary objective of this study is to quantify the relationship between palatal morphology-including vault height, angle, width, and palatal bone thickness-and the dimensions and position of the greater palatine canal (GPC) and foramen (GPF). Secondary objectives include evaluating how age and sex relate to GPC/GPF measurements, as well as describing the prevalence and anatomical variations, including shapes, of accessory (lesser) palatine canals and foramina.

Inclusion Criteria:

• Adults ≥18 years
• CBCT scans showing complete hard palate
• Presence of first maxillary molars bilaterally

Exclusion Criteria:

• Palatal surgery or trauma history
• Maxillofacial anomalies
• Palatal pathology
• Poor CBCT quality
