Bioglass 45S5 or calcium sodium phosphosilicate, is a bioactive glass specifically composed of 45 wt% SiO 2, 24.5 wt% CaO, 24.5 wt% Na 2 O, and 6.0 wt% P 2 O 5. [1] Typical applications of Bioglass 45S5 include: bone grafting biomaterials , repair of periodontal defects, cranial and maxillofacial repair, wound care, blood loss control ...
Some Sensodyne products contain calcium sodium phosphosilicate CSPS (Novamin), which appears to help with tooth sensitivity. [5] [6] A randomized clinical trial published in 2015 demonstrated that dentifrices containing 5% CSPS may have the potential to mineralize and occlude the dentine in the oral environment.
The sodium-calcium exchanger (often denoted Na + /Ca 2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na +) by allowing Na + to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca 2+).
Although the sodium-calcium exchanger has a low affinity for calcium ions, it can transport a high amount of the ion in a short period of time. Because of these properties, it is useful in situations where there is an urgent need to export high amounts of calcium, such as after an action potential has occurred. [ 17 ]

The hard ions such as calcium (Ca 2+) and magnesium (Mg 2+) adhere to the sulfonate groups, displacing sodium ions. The resulting solution of sodium ions is softened. Idealized image of water softening process involving replacement of calcium ions in water with sodium ions donated by a cation exchange resin.
