CBCT Study of Maxillary Sinus Dimensions and Greater Palatine Canal Pathway: A Retrospective Analysis
An observational study of Pneumatization, run by Cairo University.
Trial summary
The CBCT-based radiographic evaluation will be used to identify, classify, and measure the anatomical parameters of the GPC and maxillary sinus. These data will serve as a pre-surgical diagnostic guide for clinicians when performing procedures involving the posterior maxilla. Read more about this study
