Conditions

Dose Reduction, Mandibular Canal Visibility

Brief summary

The goal of this observational study is to evaluate the diagnostic accuracy of CBCT dose reduction on the mandibular canal visibility, and their effect on canal cortication compared to standard CBCT dose as a gold standard. The main question it aims to answer is: Will the lower CBCT doses affect the visualization of mandibular canal when compared to standard CBCT dose as a gold standard?
