title: [Changes in serum zinc level of periodontitis with kidney deficiency].
abstract: The study is to explore the possible relationship between the level of trace element zinc in serum and periodontitis with Kidney deficiency. The level of serum zinc in 40 cases of periodontitis and in 19 normal controls was examined by atomic absorption spectrum analysis. The results indicated that there was only a descending trend of serum zinc in periodontitis group as compared with normal group. But further analysis revealed that according to the severity of periodontitis and the theory of Syndrome differentiation in TCM, it showed that the drop of serum zinc had not only a negative correlation with the severity of periodontitis, but also was co-related to whether there was Kidney deficiency or not. Serum zinc of periodontitis with Kidney Deficiency group was significantly lower than that of normal control group as well as the group of periodontitis without Kidney deficiency (P < 0.05). The data suggested that the decline of serum zinc level is closely related to the occurring and development of periodontitis with Kidney Deficiency.
