【Abstract】 Unstimulated whole-salivary SIgA,IgG and Lysozyme(LZM)were investi-gated from patients with various degree of-periodontitis.The mean value andstandard deviation were compared with normal salivary samples from normalsubjects.There was no statistically significant difference between the normal group andperiodontitis group in SIgA value.A positive correlation was found bet-ween the patients with periodontitis and the value of IgG,Lysozyme.Both IgGand Lysozyme are higher in concentration in the patients with moderateperiodon-tiffs than those with minimum and severe periodontitis.更多还原
