Is that the same as zinc hydroxyapatite? In Italy it's pretty well known under the brand name BioRepair (which is how I discovered about it, and personally I'm very satisfied with it)

Study that comparey biorepair and sensodyne https://onlinelibrary.wiley.com/doi/full/10.1002/sca.21105 https://onlinelibrary.wiley.com/doi/full/10.1002/sca.21105

  so they tested 2 Biorepair products, but only one was effective

Probably not. Though probably both are somehow effective. In this https://www.sciencedirect.com/science/article/pii/S0300571211000832#bib0045 https://www.sciencedirect.com/science/article/pii/S030057121... they study some difference between the Zinc-nano-Hydroxyapatite vs pure nano-Hydroxyapatite. But zinc-hydroxyapatite in BioRepair may not be some Zinc-nano-Hydroxyapatite. They are the same compounds but the size of the crystals are not the same. BioRepair is advertised as "microRepair". The size of the crystals seems to matter : smaller crystals are better as they allow to get inside smaller holes to fill them, but probably also more expensive to produce.

Using an equal time of treatment, the application of CHA nanocrystals 100 nm sized produces the formation of a homogeneous coating which hides interprismatic and prismatic enamel structures when examined with SEM." Toothpaste is kind of a complex mixture that also depends on the PH and the interaction with saliva to work. Therefore probably only specific studies between the full products using a microscope could tell the better products. As a final note, the tooth mineralization is a tug-of-war (dynamic equilibrium) between demineralization and remineralization, this means that using more effective products should be used carefully and not as an excuse to compensate for bad behavior like excessive soda consumption throughout the day.
