    Summary

    This study examined human tooth canal anatomy using contrast medium and radiographs. Findings reveal common canal forms, with notable exceptions like dual canals in maxillary first molars and accessory canals.

    Area of Science:

    • Dentistry
    • Endodontics
    • Radiology

    Background:

    • Understanding root canal anatomy is crucial for successful endodontic treatment.
    • Variations in canal morphology can complicate treatment procedures.

    Purpose of the Study:

    • To investigate the detailed anatomy of human tooth root canal systems.
    • To identify common canal configurations and variations, including accessory and lateral canals.

    Main Methods:

    • Radiographs of 164 extracted human teeth were analyzed.
    • A radiopaque contrast medium was infused into the canal systems under vacuum.
    • Magnification was used for detailed examination of the radiographs.

    Main Results:

    • Canal form and number generally corresponded to root morphology.
    • Two canals were observed in the mesiobuccal roots of maxillary first molars.
    • The incidence of lateral, accessory, and furcation canals was noted.

    Conclusions:

    • The study documented typical and atypical root canal anatomies.
    • Awareness of these anatomical variations is important for endodontic treatment planning and execution.
