    Elastic bands impacting the gingival sulcus cause bacterial plaque buildup, tissue damage, and tooth extrusion. Prompt removal allows for complete tissue repair within three weeks, potentially forming an epithelial attachment.

    Area of Science:

    • Periodontology
    • Bacterial plaque pathogenesis
    • Gingival sulcus dynamics

    Background:

    • Impaction of the gingival sulcus by foreign bodies, such as elastic bands, can lead to significant pathological changes.
    • Understanding the effects of sulcus impaction is crucial for managing periodontal complications and ensuring proper tissue healing.

    Purpose of the Study:

    • To investigate the pathological effects of elastic band impaction on the gingival sulcus and surrounding dental structures.
    • To document the timeline of inflammatory responses and pocket formation.
    • To evaluate the healing process and outcomes following the removal of the impacted material.

    Main Methods:

    • Observation of gingival sulcus deformation and bacterial plaque accumulation.
    • Assessment of epithelial and lamina propria changes, including necrosis.

  • Monitoring of tooth extrusion, mobility, and inflammatory signs (color change, hemorrhage).
  • Measurement of pocket depth and evaluation of tissue repair post-removal.

    • Main Results:

    • Elastic band impaction deforms the gingival sulcus, promoting bacterial plaque growth and causing tissue necrosis.
    • Teeth become extruded, leading to premature contact, mobility, and inflammation within 7 days, with pocket formation (4-6 mm).
    • Removal of the impaction results in rapid repair, with complete restoration in approximately 3 weeks, potentially via epithelial attachment.

    Conclusions:

    • Gingival sulcus impaction by elastic bands induces a cascade of destructive periodontal events.
    • The inflammatory process and pocket formation are significant but reversible.
    • Prompt removal of the impaction facilitates complete tissue regeneration, highlighting the importance of timely intervention.
