Dentists test which root canal measuring method is more accurate

This study compares two methods for measuring root canal length during root canal treatment: a manual technique using hand instruments and a machine-assisted mechanical technique. Both methods use electronic devices called apex locators to improve accuracy. About 104 adults needing root canal on lower molars will participate, and their treatment will follow standard dental care. The goal is to find which method is more accurate and reliable to improve future dental treatments.
