Summary

Paraformaldehyde preparation (Toxavit) caused severe gingival and bone necrosis, leading to tooth loss in a patient. This highlights the risks of toxic materials in dental pulp treatments.

Area of Science:

  • Dentistry
  • Endodontics
  • Oral Pathology

Background:

  • Dental pulp inflammation requires effective treatment.
  • Paraformaldehyde-based preparations are used in endodontics.

Observation:

  • A paraformaldehyde preparation (Toxavit) was applied to an inflamed mandibular first molar (tooth #46).
  • The patient was a 30-year-old woman.

Findings:

  • Leakage from the paraformaldehyde preparation resulted in extensive necrosis.
  • Necrosis affected the gingiva and alveolar cortical bone.
  • The severe tissue damage led to the loss of the treated tooth.

Implications:

  • Paraformaldehyde preparations can cause severe local tissue damage if they leak.
