简要总结
A cross-sectional study to assess the anatomical variations of greater palatine foramen in a sample of Egyptian population using cone beam computed tomography through retrospective data analysis
详细描述
A) Setting and location:
- The CBCT Scans of this study will be obtained from the data base available at the department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Cairo University, Cairo, Egypt.
- Being a retrospective study, CBCT scans of Egyptian patients who have already been subjected to CBCT examination as part of their dental diagnosis and/or treatment planning will be included according to the proposed eligibility criteria.
B)Participants:
Based on sample size calculation, a sample of 173 hemi-palate belonging to Egyptian individuals will be examined.
