Summary

This study looked at how accurately dental students can assess their own root canal treatments compared to expert evaluations. Over 200 patients received routine care from students using two different file systems. Researchers compared the students' self-assessments with reviews by experienced dentists to see if students' judgments matched up, and whether the type of file system made a difference.
