Values are means ± S.E.M.
P-values for comparisons of bite locations within adults: between P and RII, P<0.018; for all other comparisons, P<0.001(except between molars in adults, which were not significant).
P-values for comparisons of bite locations within juveniles:between I,C and P, P<0.27 (not significant); between P and RII, P<0.001; between I,C and RII, P<0.002.
P-values for comparisons between adults and juveniles within each bite location: P<0.02.
