The Effect of Toothpastes Containing Natural Ingredients Such As Theobromine and Caffeine on Enamel Microhardness: An In Vitro Study
Table 2
Enamel microhardness values after brushing in each four groups.
| Group | Hardness mean value ± SD (KHN) | value | Demineralization hardness ± SD | Remineralization hardness ± SD | Diff 2 ± SD |
| 1 (theobromine) | 151.09 ± 82.76 | 289.34 ± 100.55 | 138.24 ± 110.89 | 0.001 | 2 (caffeine) | 151.20 ± 64.03 | 231.05 ± 49.82 | 79.84 ± 56.86 | 0.001 | 3 (fluoride) | 146.29 ± 69.26 | 291.82 ± 94.51 | 145.53 ± 84.43 | 0.001 | 4 (distilled water) | 149.98 ± 64.42 | 209.15 ± 57.24 | 59.16 ± 53.38 | 0.001 | | 0.996 | 0.004 | 0.003 | |
