Abstract

The purpose of this study was to evaluate the effect of galvanic current between different metallic restorations on human saliva. The rate of salivary flow and concentrations of IgG, IgM, sIgA and lactoferrin were measured. In this study, unstimulated whole saliva collected before restoration was regarded as control group and unstimulated whole saliva collected 10 minutes, 1 day, 1 week, and 1 month after restoration were regarded as experimental groups. Following results were obtained from this study. 1. There were some differences in values of salivary flow rate between experimental groups, but the changes in values compared to those of the control group were not statistically significant(P>0.05). 2. Measurements of major antibacterial components of saliva showed that while the concentrations of IgG and IgM decreased significantly 1 week and 1 month after restoration(P<0.05), changes in values of sIgA and lactoferrin were not statistically significant(P>0.05). 3. In vitro measurements of galvanic currents decreased sharply in the first 20 seconds and thereafter decreased gradually. Galvanic current values measured in the early stages were greatly varied, but after 2 hours, the values in all groups approximated each other.
