This study found a strong correlation between the external root shape and internal root canal anatomy in maxillary molars using 3D imaging. These findings support using 3D models for endodontic training.

Area of Science:

  • Dental Anatomy
  • Biomedical Imaging
  • Quantitative Morphology

Background:

  • Understanding the relationship between external root morphology and internal root canal anatomy is crucial for endodontic procedures.
  • Previous studies have explored root canal morphology, but detailed analysis correlating external and internal features using advanced imaging is limited.

Purpose of the Study:

  • To qualitatively analyze the relationship between the external and internal macromorphology of the root complex in maxillary molars.
  • To quantitatively assess the correlation between the outer root surface shape and the root canal shape using fractal dimension analysis.

Main Methods:

  • X-ray computed transaxial microtomography was used to analyze five permanent maxillary molars.
  • 3D volume reconstruction, segmentation, and surface rendering were performed to visualize enamel, dentine, and pulp spaces.

  • Fractal dimension analysis was applied to quantify the correlation between external and internal root morphology.

    • Main Results:

    • A strong agreement was observed between the number, position, and cross-section of root canals and the macrostructures of the root complex.
    • Fractal dimension analysis revealed a high correlation between the shape of the root canals and the overall shape of the roots.

    Conclusions:

    • The study demonstrates a significant relationship between external root morphology and internal root canal anatomy.
    • The generated 3D volumetric data can serve as a valuable platform for preclinical training in fundamental endodontic procedures.
