Background and study aims
Periodontal disease (PD) associated with type 2 diabetes mellitus (DM2) is a chronic systemic condition that affects the structures supporting the teeth. Poor blood sugar control in DM2 patients contributes to the development of more severe PD, leading to systemic inflammation and the development of other diabetic complications. Recently, deficiencies in magnesium and zinc have been reported in patients with PD-DM2. It has been described that these elements play a role in regulating the inflammatory process as well as in the recovery and healing of periodontal tissues.
Non-surgical periodontal treatment (NSPT) is the gold standard for managing periodontal disease. This involves mechanical instrumentation of the root surfaces to reduce the factors contributing to the development of PD. Clinical practice guidelines for PD management have suggested the use of complementary treatments alongside non-surgical periodontal treatment to reduce clinical parameters of the disease, achieve remission, and stabilize periodontal tissues. The use of magnesium and zinc as supplements to non-surgical periodontal treatment has not been reported.
Therefore, the aim of this study is to evaluate the effects of NSPT combined with oral supplementation of magnesium oxide and zinc gluconate for 30 days on clinical periodontal characteristics, oxidative stress, and antioxidant enzymes compared to those who received only NSPT.

Who can participate?
Patients aged 18-60 years with periodontal diseases associated with type 2 diabetes mellitus

What does the study involve?
Patients who visited the department for the first time to receive periodontal treatment were assessed clinically and blood samples were taken. NSPT and oral supplementation with magnesium oxide and zinc gluconate were started weekly for 30 days. After the interventions, another clinical periodontal assessment and blood sample collection were performed.

What are the possible benefits and risks of participating?
It is expected that this treatment will help improve oral and systemic health conditions by reducing oxidative stress and increasing antioxidant enzymes. Possible risks of NSPT included pain, inflammation, and bleeding in the intervention area. Regarding the use of supplements, the risks included diarrhea, headache, stomach pain, and vomiting.

Scientific titleThe effects of non-surgical periodontal treatment plus zinc and magnesium supplementation on oxidative stress and antioxidant enzymes in type 2 diabetes patients
Study objectivesIt has been proposed as a hypothesis that supplementation with Zn and Mg as complements to non-surgical periodontal treatment supports the improvement of periodontal clinical conditions through the regulation of oxidative stress and the increase of antioxidant enzymes superoxide dismutase and catalase
Ethics approval(s)

Approved 29/10/2018, The research ethics committee of the Institute of Health Science from Veracruzana University (Av Luis Castelazo Ayala S/N Industrial Ánimas, Xalapa, Veracruz, 91190, Mexico; +52 (0)2288426233; ceiics@uv.mx), ref: No. 010/2022

Health condition(s) or problem(s) studiedTreatment for periodontal diseases in type 2 diabates patients
InterventionThe control group received non-surgical periodontal treatment and oral physiotherapy for 30 days (n = 19). The experimental group received non-surgical periodontal treatment plus 50 mg of zinc gluconate and 500 mg of magnesium oxide in oral administration for 30 days (n = 20).
Intervention typeProcedure/Surgery
Primary outcome measure(s)

1. Clinical periodontal parameters such as deep on probing, clinical attachment level, bleeding on probing, and periodontal inflamed surface area, measured using periodontogram at baseline and 30 days after treatment
2. Biochemical parameters such as glucose levels, zinc levels, magnesium levels, total cholesterol levels, triglycerides levels, HDL-C, and LDL-C, measured using biochemical analyses at baseline and 30 days after non-surgical periodontal treatment

Key secondary outcome measure(s)

1. Oxidative stress measured using lipoperoxidation reaction and MDA levels at baseline (day 0) and 30 days after the interventions
2. Antioxidant enzymes measured using commercial kits (superoxide dismutase and catalase levels) at baseline (day 0) and 30 days after the interventions
