• | First CBCT-based evaluation of greater palatine grooves in an Iraqi population. |
• | Identified up to three palatine grooves, a novel anatomical finding. |
• | M7 region showed deeper and more frequent grooves than M6. |
• | Significant biological sex differences in groove depth, crests, and bridges. |
• | Findings improve safety margins for palatal implants and local anesthesia. |
Summary |
Background |
The greater palatine groove (GPG), crest, and bridge show different forms; to avoid problems during dental implant and periodontal surgeries, it is important to know how they change their forms. It is the first time to be inspected in the Iraqi population.
Methods |
Two hundred patients (100 males and 100 females), ranging from 18 to 86 years old, had their CBCT scans retrospectively analysed. The first (M6) and second molar (M7) areas were examined for the presence and frequency of GPGs, crests, and bridges. Using Chi-square and t -tests with a significance level of 0.05, the data was analysed using SPSS v23.
Results |
The GPG was more often seen in the M7 area and in male cases. Three grooves were found, which had not been reported before. The M6 region mostly had flat grooves (93%), but the M7 region had shallow (35%) and deep (10%) grooves. Crests and bridges were also more common in males, with 6 M6 cases and 25 M7 cases showing bridges.
Conclusion |
The morphology of GPG exhibits significant anatomical variability. Acknowledgement of these variations is crucial to mitigate neurovascular injury risks during implant placement and local anaesthesia. This is the first time that these structures have been evaluated using CBCT in the Iraqi population. It provides dentists with useful information about their anatomy.
