Table 1
Enamel microhardness in the initial and demineralization phases in each group.
| Group | Hardness mean value ± SD (KHN) | value | Initial hardness ± SD | Demineralization hardness ± SD | Diff 1 ± SD |
| 1 (theobromine) | 235.96 ± 87.09 | 151.09 ± 82.76 | 84.86 ± 47.49 | 0.001 | 2 (caffeine) | 216.40 ± 66.75 | 151.20 ± 64.03 | 65.20 ± 58.74 | 0.001 | 3 (fluoride) | 214.48 ± 64.14 | 146.29 ± 69.26 | 68.18 ± 37.42 | 0.001 | 4 (distilled water) | 247.37 ± 65.44 | 149.98 ± 64.42 | 97.39 ± 64.52 | 0.001 | | 0.457 | 0.996 | 0.146 | |
