Design outcomes

Primary

Measure	Time frame
Number of roots in maxillary second molars and root canal configuration, recorded after being observed visually by two experienced Endodontics who performed CBCT image evaluation and data analysis across various levels (axial, coronal, sagittal, oblique, and 3D). Measured at a single timepoint for each patient and two experienced endodontics examined the CBCT images again 2 months later to ensure the accuracy of the recorded results.	—

Secondary

Measure	Time frame
The symmetry of the number of roots in maxillary second molars and symmetry in the numbers and configuration of the root canal, recorded after being observed visually by two experienced Endodontics who performed CBCT image evaluation and data analysis across various levels (axial, coronal, sagittal, oblique, and 3D). Measured at a single timepoint for each patient and two experienced endodontics examined the CBCT images again 2 months later to ensure the accuracy of the recorded results.	—
