Inclusion Criteria

• Fully maturated and erupted maxillary permanent premolars of Egyptian patients, males or females.
• Intact maxillary premolars' roots without fractures or cracks.
• Maxillary Premolars without posts or previous root canal treatment.
• CBCT scans of different fields of view could be included as long as it shows maxillary premolars.
