Table 2.
Enamel and root surface lesion depths following exposure to select beverages.
| Lesion Depth (μm) | Beverage | ||||
|---|---|---|---|---|---|
| 100% Apple Juice | Coke® | Diet Coke® | Gatorade® | Red Bull® | |
| Enamel | 57 ± 6a,1 | 92 ± 62 | 61 ± 41 | 131 ± 83 | 100 ± 52 |
| Root | 77 ± 3a,1 | 101 ± 32 | 66 ± 23 | 118 ± 54 | 111 ± 45 |
| Enamel vs. Root, P -value | 0.001b | 0.040b | 0.074b | 0.035b | 0.012b |
Windows in enamel or root surfaces were exposed to beverages for 25 hours with beverages replaced every 5 hours. Teeth were sectioned following beverage exposure and lesion depths were measured.
a
Values are means ± SD. Within group comparisons; means within a row with different superscript numbers are significantly different. Statistical test was one-way analyses of variance with post-hoc Tukey’s studentized range (HSD) test; P < 0.05.
b
Between group comparisons; P -values for enamel vs. root lesion depth comparisons using the two-sample t-test.
