简要总结
A cross-sectional study to assess variations in root canal curvatures of the Permanent Mandibular First and Second Molars in a Sample of Egyptian Population using cone beam computed tomography through retrospective data analysis
详细描述
A) Study design and setting
- Study Design: An observational Cross-sectional Study
- Setting and Location: 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. The CBCT scans will be obtained from the data base available at the department of Oral and Maxillo-facial Radiology, Faculty of Dentistry, Cairo University, and a private Oral Radiology center, Cairo, Egypt.
B) Participants:
Based on sample size calculation, a sample of 272 canals of mandibular first and second permanent molars belonging to Egyptian individuals will be examined. The selection of the scans to be included will be based on the following eligibility criteria.
