Comparison of the efficacy for different caries risks. Except for patients with moderate risk (OR = 0.32, 95% CI 0.01–8.27), there were significant differences between micro-invasive treatments and non-invasive treatments (low risk: OR = 0.24, 95% CI 0.08–0.72; low to moderate risk: OR = 0.38, 95% CI 0.18–0.81; moderate to high risk: OR = 0.17, 95% CI 0.10–0.29; and high risk: OR = 0.14, 95% CI 0.07–0.28)
