Causal relationship between 14 micronutrients and chronic periodontitis: a Mendelian randomization study

Area of Science:

• Genetics and Public Health
• Nutritional Epidemiology

Background:

• Chronic periodontitis is a prevalent global inflammatory condition.
• Micronutrients influence health and disease progression, but their causal role in periodontitis is unclear.

Purpose of the Study:

• To investigate the potential causal associations between 14 micronutrients and chronic periodontitis using a Mendelian randomization approach.

Main Methods:

• Utilized genome-wide association study data from the FinnGen consortium.
• Employed five Mendelian randomization methods and sensitivity analyses to assess 14 micronutrients.
• Data for micronutrients sourced from OpenGWAS and UK Biobank Study.

Main Results:

• A significant inverse association was found between vitamin D and chronic periodontitis risk (OR: 0.605).
• No statistically significant causal relationship was identified for the other 13 investigated micronutrients.
• Sensitivity analyses confirmed the robustness and reliability of the findings.

Conclusions:

• Vitamin D may have a protective causal effect against chronic periodontitis.
• The study highlights a potential role for vitamin D in periodontitis prevention.
• Further randomized controlled trials are recommended to validate these findings and explore therapeutic implications.
