Summary

This study details a rare case of multiple dens invaginatus (DI) in a young boy, affecting both upper and lower teeth. The findings suggest a link between DI and other developmental anomalies, classifying cases into two distinct types.

Area of Science:

  • Dentistry
  • Medical Genetics
  • Developmental Biology

Background:

  • Dens invaginatus (DI) is a developmental anomaly of teeth.
  • Multiple DI cases are rare, necessitating further research into associated conditions.

Observation:

  • A unique case of bilateral multiple dens invaginatus (DI) is presented in an 11-year-old boy.
  • The patient exhibited anomalies in maxillary central incisors, mandibular canines, and first premolars.
  • Associated findings included steeple-head, mild mental retardation, skull hyperostosis, and hypoplastic cervical vertebra.

Findings:

  • The study identified two types of multiple DI: isolated DI and DI with systemic anomalies.
  • Morphological differences in central incisors were observed between these two types.

  • This case contributes to the understanding of DI's complex etiology and presentation.

    • Implications:

    • Highlights the importance of thorough examination for systemic anomalies in patients with multiple DI.
    • Suggests potential genetic or developmental pathways linking dental and skeletal abnormalities.
    • Informs diagnostic and management strategies for dens invaginatus and related conditions.
