Why it matters for dental

Brazilian researchers created calcium cyclohexaphosphate that matched fluoride toothpaste protection against enamel erosion in lab tests, giving practices a potential non-fluoride option for patients who prefer or cannot use fluoride.

Key points

  • Researchers at São Paulo State University (UNESP) and Federal University of São Carlos synthesized calcium cyclohexaphosphate (CaCHP) by exchanging sodium for calcium in a cyclic phosphate ring.
  • Eight toothpastes were formulated with CaCHP at 0.25 %, 0.5 %, and 1 %, NaCHP at the same concentrations, a placebo, and a 0.24 % NaF control.
  • On pre-softened bovine enamel blocks, 1 % CaCHP preserved surface hardness comparably to 0.24 % NaF through four citric-acid challenges.
  • NaCHP alone showed no protective effect at any concentration tested; CaCHP required the calcium ion incorporated into the molecule.
