Summary

This completed study looked at 102 people needing root canal treatment on a back upper molar. Dentists used either direct vision, magnifying loupes, or a dental microscope to see better during the procedure. The goal was simply to measure how long each step took, not to test a new treatment or improve health outcomes.
