Summary:This study was aimed at determining whether dental caries is associated with induction of the systemic immune system or cytokine response. For this purpose, 85 children from Den Pasar, Bali, Indonesia, aged 6-7 years, were examined clinically and blood plasma was obtained via finger puncture. The concentrations of the acute-phase protein alpha(1)-acid glycoprotein (AGP), total IgG and the specific IgG and IgM immunoglobulins against Streptococcus mutans were determined. Immunoelectrophoresis was used for the determination of the AGP concentration and ELISA for IgG and IgM detection. The mean dmft of the whole group was 8.8 +/- 2.9, the mean number of infected pulps was 3.9 +/- 2.2 and the mean number of abscesses was 0.5 +/- 0.8. The plasma concentration of AGP ranged between 0.13 and 1.6 mg/ml serum (mean 0.86 +/- 0.26 mg/ml). Stepwise regression analysis revealed that the concentration of IgG against S. mutans (log-transformed) was significantly correlated with dmft (adjusted r(2) = 0.083, standardized beta coefficient = 0.31, p = 0.008). When the concentration AGP was included in the model the correlation improved significantly (for IgG: adjusted r(2) = 0.157, standardised beta coefficient = 0.36, p = 0.002; for AGP: beta coefficient = -0.30, p = 0.009). The results suggest a relationship between caries and systemic parameters of inflammation. On the basis of this, severe caries might have consequences on the general health of the subject.
