This study examined the root canal anatomy of 104 human maxillary second molars, revealing complex canal numbers and non-circular cross-sections in most teeth at both mid-root and apical levels.

Area of Science:

  • Dentistry
  • Endodontics
  • Dental Morphology

Background:

  • The Royal Dental College in Copenhagen possesses a significant collection of human teeth.
  • This collection includes 104 single-rooted, permanent maxillary second molars.
  • Understanding root canal anatomy is crucial for effective endodontic treatment.

Purpose of the Study:

  • To analyze the root canal morphology of permanent maxillary second molars.
  • To detail the number, position, and cross-sectional shape of root canals.
  • To provide data relevant to clinical dentists, endodontists, and dental morphologists.

Main Methods:

  • 104 human permanent maxillary second molars were sectioned at mid-root and apical levels.
  • A stereomicroscope was used to examine canal number, position, and cross-section.

  • Variables were registered at both coronal-apical and middle-apical third junctions.

    • Main Results:

    • Mid-root: 25.96% had 1 canal, 34.62% had 2, and 39.42% had 3 canals.
    • Mid-root: 63.51% of canal cross-sections were non-circular (C, Y, hourglass, or oval shapes).
    • Apically: 35.58% had 1 canal, 37.49% had 2, and 26.92% had 3 canals; 64.32% were non-circular.

    Conclusions:

    • Maxillary second molars exhibit complex root canal systems with variations in canal number and morphology.
    • A high prevalence of non-circular canal cross-sections was observed at both mid-root and apical levels.
    • Detailed anatomical knowledge is essential for successful endodontic procedures in these teeth.
