Context: Periodontal tissue destruction is caused by an inappropriate host response to microorganisms. Diabetes is a metabolic disease and most of its complications are due to hyperglycemia. Periodontitis is considered as its sixth complication. Micronutrients such as zinc, copper and iron are essential for human health. There is accumulating evidence that the metabolism of several trace elements is altered in diabetes mellitus and that these nutrients might have specific roles in the pathogenesis and progress of this disease and its complication. An association between micronutrients and periodontitis has also been suggested by preliminary studies. However, till date there is a lack of relevant clinical data. Aim: This study was designed to estimate and compare the serum levels of zinc, copper and iron in diabetes mellitus type 2 patients and healthy individuals with and without periodontitis. Setting and Design: Single centre case-control study. Subjects and Materials: This study included 150 subjects, 50 in each group. Group 1 comprised of 50 subject with diabetes mellitus type 2 and periodontitis. Group 2 comprised of 50 subjects with chronic periodontitis and Group 3 comprised of 50 control subjects. Atomic absorption spectrophotometry method was used to measure clinical level of zinc and copper in serum. Estimation of serum iron levels was done by bathophenanthroline method. Statistical analysis: The results obtained were tabulated and subjected to statistical analysis by analysis of variance and Tukey multiple comparison tests using statistical software SPSS version 17. Results: The results showed that the serum levels of zinc decreased and serum levels of iron and copper increased in diabetes patients with periodontitis compared to healthy individuals with and without periodontitis. Conclusion: Imbalance of Zinc, copper and iron levels in the serum can predispose an individual to the risk of developing periodontitis.
