Help understanding the difference between two toothpastes fluoride content

Question

I’m comparing two different toothpaste that I’m interested in switching to. The first toothpaste outlines the fluoride content as follows- sodium monofluorophosphate 0.76% (0.15% w/v fluoride ion)

The second toothpaste outlines the fluoride content as follows- Sodium fluoride (0,243 % p/p)

Is one better than the other? If so, why is that?

Answer 1

I haven’t seen p/p to list a concentration before.

0.15% w/v means that there is 0.15 grams/100ml of toothpaste.
