Histopathological changes in primary teeth after trauma were studied. While specific clinical diagnoses didn't correlate with these changes, combined histological factors showed links to clinical findings in children.

Area of Science:

  • Pediatric Dentistry
  • Oral Pathology
  • Dental Traumatology

Background:

  • Traumatic dental injuries are common in primary teeth.
  • Understanding histopathological responses is crucial for managing these injuries.
  • Pulpal calcification morphology following trauma requires further investigation.

Purpose of the Study:

  • To investigate histopathological changes in traumatized primary teeth.
  • To correlate pulpal calcification morphology with clinical findings.
  • To analyze responses using advanced microscopy and data analysis.

Main Methods:

  • Analysis of 123 primary teeth from 98 children (9-108 months old) post-trauma.
  • Utilized light, scanning, and transmission electron microscopy.

  • Employed computerized inductive analysis for clinical and histological data.

    • Main Results:

    • Intrusion luxation was the most frequent diagnosis (54%).
    • Pulpal obliteration (<1/4 lumen) occurred in 41% of teeth.
    • Denticles, when present (21%), were often bone-like (80%); occluding tissues were dentin-like (49%), bone-like (19%), or fibrotic (9%).

    Conclusions:

    • Histopathological changes in primary teeth post-trauma showed varied responses.
    • No direct correlation was found between specific clinical diagnoses and observed histological changes.
    • Certain combinations of histological parameters demonstrated correlations with clinical findings.
