Means followed by different letters in the same line differ in relation to fluoridated water (p <0.05; Mann-Whitney test).sd= standard deviation.

DF-R = mean number of decayed and filled roots; D-R = mean number of decayed roots; F-R= mean number of filled roots; S-R= mean number of exposed yet sound roots.
