US miles, UK miles or nautic miles? Imperial units are always crap (feet/s ?)

m/s is the best, everyone know aprox. what is an meter and an second to know the velocity, but not so easy with km and a hour.. 50km/h seems slow, but not so 13 m/s.

Andi's Writeup

Recent research shows significant advances in using hydrogels to restore lost teeth and dental tissue through several approaches:

Injectable Hydrogels for Tooth Pulp Regeneration

  • Researchers at NJIT developed a first-of-its-kind injectable hydrogel that triggers the body to regenerate lost tooth pulp, funded by a $3 million NIH grant[^3]
  • The material recruits dental pulp stem cells to rebuild tissue without requiring live cells, making it viable for off-the-shelf use[^3]
  • Early animal trials showed formation of soft tissue, blood vessels, and nerve bundles within a month[^3]

Enamel Regeneration

  • Scientists in China created a gel containing mineral clusters that can stimulate crystal regrowth to restore eroded tooth enamel[^18]
  • Tel Aviv University researchers developed a water-based hydrogel that encourages bone regrowth, potentially transforming dental implant procedures[^5]
  • USC researchers engineered peptide-based hydrogels that can rebuild tooth enamel structure and restore early cavity damage[^23]

Periodontal Tissue Engineering

  • Hydrogels are being used as scaffolds to regenerate periodontal ligament, alveolar bone, and cementum[^2]
  • Key components include:
    • Natural polymers like chitosan, sodium alginate, and hyaluronic acid
    • Synthetic polymers such as polyethylene glycol and gelatin methacryloyl
    • Bioactive substances including antibiotics, growth factors, and stem cells[^2]

Future Development

  • Japanese researchers aim to begin human trials for tooth regeneration within 6 years[^20]
  • Current challenges include:
    • Creating sufficient blood vasculature
    • Controlling bacterial growth
    • Improving mechanical properties
    • Achieving complete periodontal regeneration[^2]
