Table 2. Integrated mineral loss (ΔZ, vol% μm), average mineral loss (R, vol%) and lesion depth (LD, ?m) of enamel from each treatment group.
| Treatment | ΔZ (%vol. μm) | R (%vol) | LD (μm) |
|---|---|---|---|
| TiF4 | 1100.7±803.2c | 19.9±3.7c | 68.3±33.4c |
| NaF | 1680.0±538.3bc | 20.9±4.9bc | 86.9±29.1bc |
| Chlorhexidine | 3262.7±909.6a | 33.9±6.4a | 104.3±29.2abc |
| Placebo | 3374.6±1636.9ab | 28.9±6.5ab | 162.3±64.7ab |
| Control | 4455.3±1176.4a | 29.4±5.3a | 156.1±27.1a |
Different letters show significant differences among the treatments (per column).
ΔZ and R-values are displayed as mean ± SD (ANOVA and Tukey's test, p<0.0001).
LD is presented as median ± CI (Kruskal-Wallis and Dunn's test p<0.0001).
From 24 samples, the final number was: TiF4 (n=14), NaF (n=12), CHX (n=15), placebo (n=11) and control (n=15). The samples were lost during the preparation for TMR.
