Measures of central dispersion for change in microhardness of the groups.

Group	Mean ± SD	Maximum	Minimum
Control	0.18 ± 0.91^a	2.55	−0.59
E	38.89 ± 5.88^c	46.03	29.93
P	33.12 ± 8.02^c	42.70	24.04
PRF	22.53 ± 10.19^b	39.63	6.79
RF	25.53 ± 6.30^b	36.08	11.40
F	25.24 ± 10.31^b	37.50	8.90
PF	23.45 ± 5.98^b	31.55	14.30

SD: Standard deviation, E: Erosion, P: CAP, PRF: CAP + Enamelast, RF: Enamelast, F: FluoroDose, PF: CAP + FluoroDose. Different lowercase letters indicate significant differences (). The same lowercase letters indicate lack of statistically significant difference between the two subgroups ().
