Accessory canals are common in primary maxillary molars, especially in the apical third. This highlights the complex internal anatomy and need for careful endodontic treatment.

Area of Science:

  • Dentistry
  • Endodontics
  • Pediatric Dentistry

Background:

  • Primary maxillary molars have complex internal anatomy.
  • Accessory canals can impact endodontic treatment outcomes.

Purpose of the Study:

  • To characterize the internal anatomy of primary maxillary molars.
  • To evaluate the presence and distribution of accessory canals using micro-computed tomography (micro-CT).

Main Methods:

  • Micro-computed tomography (micro-CT) was used to scan 17 primary maxillary molars.
  • Image analysis was performed using ImageJ, CTan, and CTvol software.
  • Accessory canals were identified, counted, and categorized by root third.

Main Results:

  • 68.08% of analyzed roots had at least one accessory canal.

Published on: January 17, 2025

  • The apical third had the highest prevalence and number of accessory canals (42.71%).
  • The cervical third had the lowest prevalence and number of accessory canals (17.71%).

    • Conclusions:

    • Accessory canals are highly prevalent in primary maxillary molars, particularly in the apical third.
    • The complex internal anatomy necessitates thorough endodontic management.
    • Micro-CT is a valuable tool for characterizing root canal morphology.
