2. New Zealand Maori were the group with the lowest non-zero decay rate,
with only .01 percent of their teeth decayed. That means onlyone in every
10, 000 teeth were decayed among the Maori. Since there are 32 teeth in
every mouth, that means only one in every 312 people had any tooth decay
among primitive Maori
i didn't get from the numbers ,what is the present rate of tooth decay in
North america or europe, if i look at my mouth as an average ,it is pretty
bad.
It is a wonderful post.
thanks
