About the research
the current study will be directed to evaluate the anatomical variations of the palatal canal in maxillary permanent molars using CBCT
Read the full description
The study will be conducted as a retrospective study. CBCT on maxillary permanent molars will be obtained from a group of patients who need CBCT for orthodontic, endodontic, or surgical issues. A total of one hundred patients aged between 8 and 25 years will be included. Canal configuration, number of canals, curvature, apical anatomy, and presence of accessory canals will be assessed in axial, sagittal, and coronal planes.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- CBCT scans of patients 8-25 years.
- Palatal root completely visible from the cervical region to the apex.
- Adequate CBCT image quality.
- No significant artifacts obscuring the palatal root/canal.
Exclusion Criteria:
- Previous root canal treatment.
- Extensive root resorption.
- Root fracture.
- Periapical surgery involving the palatal root.
- Extensive restorations producing severe artifacts.
- Developmental anomalies that prevent reliable assessment

What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
CBCT evaluation
Time frame: 1 month
To assess the prevalence of:- Single vs. multiple palatal canals
- Canal bifurcation and merging
- Apical foramina
- Apical delta
- C-shaped or other unusual configurations
- Canal curvature
- Accessory canals
Secondary measures
