Never used Ipana toothpaste, we were a Colgate household (lol!), but I remember the commercials.
My grand parents had tooth powder in the late seventies. Crest I think. It was fun using it for some reason.
We used whatever was cheapest.
Aim, IIRC, was one of them.
I quit using tooth past back in 1968. Started using baking soda and salt, then just baking soda. I have had ONE cavity since I started doing that. Still have all my teeth except wisdom teeth.
