This case report details an unusual four-rooted primary upper second molar in a young male patient. This rare dental anomaly may represent an extreme form of root bifurcation.

Area of Science:

  • Dentistry
  • Human Anatomy
  • Developmental Biology

Background:

  • Primary molars play a crucial role in maintaining occlusion and guiding permanent tooth eruption.
  • Variations in root morphology can impact dental treatment planning and outcomes.

Observation:

  • A young male patient presented with bilateral extraction of primary upper second molars.
  • The left molar exhibited a typical root configuration, while the right molar displayed an anomalous four-rooted structure.
  • The accessory root was identified as mesiopalatal with a rounded cross-section.

Findings:

  • The right primary upper second molar possessed four distinct roots, deviating from the usual anatomy.
  • The accessory mesiopalatal root's morphology suggests a potential extreme manifestation of root bifurcation.

Related Experiment Videos

  • Other roots presented typical morphology consistent with primary molar root development.

    • Implications:

    • This finding contributes to the understanding of rare dental anomalies in primary dentition.
    • Awareness of such variations is essential for accurate diagnosis and management in pediatric dentistry.
    • Further research into the genetic and developmental factors underlying extreme root bifurcation is warranted.
