  2. *P is significant at the 5% level of significance. Different letters in the same column show significant differences between each 2 segments of the teeth (Mann–Whitney test, P < .05). The same letters in the same column show nonsignificant differences between each 2 segments (Mann–Whitney test, P > .05)
