Summary
This study reveals unique C-shaped root canal systems in mandibular second molars. Three-dimensional reconstruction highlighted variations in root structure and canal anatomy, crucial for endodontic treatment.
Area of Science:
- Dentistry
- Endodontics
- Dental Anatomy
Background:
- C-shaped root canal morphology presents unique endodontic challenges.
- Understanding variations in mandibular second molars is critical for successful treatment.
Purpose of the Study:
- To investigate the three-dimensional (3D) morphology of C-shaped root canal systems in mandibular second molars.
- To analyze the root structure and canal configuration of these teeth.
Main Methods:
- Two mandibular second molars with suspected C-shaped canals were selected.
- Serial cross-sectioning and digitization of sections were performed.
- Surface representation was used for 3D reconstruction.
Main Results:
- The first molar exhibited a single root with one C-shaped canal and two foramina.
- The second molar had double roots, one with a C-shaped canal and another thin canal, sharing a common foramen.
Conclusions:
- Mandibular second molars can display complex C-shaped root canal configurations.
- Detailed 3D analysis is essential for comprehending root canal anatomy and guiding endodontic procedures.
