Blood Contamination in Saliva: Impact on the Measurement of Salivary Oxidative Stress Markers

Figure 6

The effect of blood leakage after dental hygiene treatment on markers of oxidative stress and antioxidant status in saliva of control (a–d) and gingivitis (e–h) patients. (a, e) Salivary AOPP concentrations, biomarker of oxidative damage to proteins. (b, f) Salivary AGEs concentrations, biomarker of carbonyl stress. (c, g) Salivary FRAP concentrations, biomarker of antioxidant status. (d, h) Salivary TAC concentrations, biomarker of antioxidant status. , , and .
