Abstract
Aim:The purpose of the study was to evaluate the serum levels of zinc (Zn) and magnesium (Mg) in type 2 diabetes mellitus (DM) with periodontitis patients and to correlate them with the levels of serum cholesterol, high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c), and triglycerides among the study subjects.Materials and Methods:A total of 600 subjects participated in the study, who were divided into four groups as control healthy individuals (group I), type 2 DM without periodontitis (group II), type 2 DM with periodontitis (group III), and periodontitis subjects without DM (group IV), matched for age, sex, and duration of diabetes. Serum concentrations of glucose, total cholesterol, triglycerides, HDL-c, Zn, and Mg were measured using enzymatic methods in an UV absorption spectrophotometer, and LDL-c was calculated using Friedwald's formula. Student's t-test, Pearson correlations, and analysis of variance (ANOVA) tests were used for statistical analysis.Results:The serum zinc level was found to be significantly increased in type 2 DM without periodontitis (group II) and periodontitis subjects without type 2 DM (group IV) (P < 0.0001), and the level was lowered in type 2 DM with periodontitis (group III) when compared to control. The serum Mg level was found to be significantly decreased (P < 0.0001) in group II, group III, and in group IV, when compared to control. We found a significant increased level of serum total cholesterol and LDL-c and decreased triglycerides and HDL-c in type 2 DM subjects with periodontitis (group III, P < 0.0001).Conclusion:Patients with DM and periodontitis had altered metabolism of Zn and Mg which were linked to increased values of serum cholesterol and LDL-c and decreased HDL-c, contributing to the progression and complications of type 2 DM with periodontitis.
