Association Between C-Shaped Root Canal Configuration in Mandibular Second Molars and Radicular Grooves in Mandibular First Premolars: A CBCT-Based Study in a Western Chinese Population.
BACKGROUND C-shaped root canal configurations (CSRCs) in mandibular second molars (MSMs) and radicular grooves (RGs) in mandibular first premolars (MFPs) are anatomical variations that may affect endodontic procedures. However, their relationship within the same individual remains unclear. This study investigated the a...
