In the multifactorial pathogenesis of periodontitis, there are still unknown factors influencing the outcome of the disease.
An association between magnesium and periodontitis has been suggested by preliminary studies. However, relevant clinical data are lacking.
We investigated the association between magnesium status and periodontal health in a population-based analysis.
Subjects taking Mg drugs showed less attachment loss (p<0.01) and more remaining teeth than did their matched counterparts.
These results suggest that nutritional magnesium supplementation may improve periodontal health.
