Tooth extraction can leave remnants of the desmodont (periodontal ligament) on the root surface. Ultrasound and low-frequency vibrations during sheep tooth extraction increased desmodont-free root surfaces.

Area of Science:

  • Dentistry
  • Biomaterials Science
  • Biomedical Engineering

Context:

  • Tooth extraction procedures can result in varying amounts of desmodont (periodontal ligament) remaining on the root surface.
  • Assessing the remaining desmodont is crucial for understanding root surface integrity post-extraction.
  • Computerized optical analysis offers a method to quantify desmodont remnants after staining with toluidine blue.

Purpose:

  • To investigate the factors influencing the amount of desmodont remaining after tooth extraction.
  • To evaluate the efficacy of toluidine blue staining and computerized optical analysis in quantifying desmodont remnants.
  • To compare desmodont remnants after clinical human tooth extraction and mechanical vibration in sheep teeth.

Summary:

  • Following the extraction of 102 human teeth and loosening of 24 sheep teeth, the remaining desmodont area was quantified using toluidine blue staining and optical analysis.

  • In most cases, no specific parameters were found to significantly influence the amount of desmodont remaining on human tooth roots.
  • However, tooth extraction in sheep pre-treated with ultrasound or low-frequency vibrations showed a greater proportion of desmodont-free root surfaces.

    • Impact:

    • This study provides insights into root surface characteristics after tooth extraction, potentially informing procedures aimed at minimizing tissue damage.
    • The findings suggest that specific mechanical vibrations, like ultrasound and low-frequency vibrations, may alter desmodont remnants during tooth loosening.
    • The methodology developed allows for objective quantification of desmodont remnants, aiding future research in periodontology and restorative dentistry.
