- •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.
- •CBCT scans of 0.2 mm voxel resolution {the maximum voxel size accepted for endodontic imaging}
