Looking to Maintain a Beautiful Smile? Search no Further

By Michael McBurney

What do you notice about a person? Is it their hair? Maybe their eyes? Their skin? For me, it is teeth. I notice smiles and especially notice if teeth when are well maintained. For this reason, today’s main citation caught my attention.

Eighty-six individuals (63 nonsmokers and 23 smokers) with chronic periodontitis were evaluated for healing and reduced probing depth (PD) at baseline and 8-16 weeks after scaling and root planing. Dietary intake of fruits and vegetables, β-carotene, vitamin C, α-tocopherol, and omega-3 fatty acids (ALA, EPA & DHA) were associated with reduced PD in nonsmokers (but not smokers). The authors report that daily supplementation with 300 mg DHA and EPA appeared to benefit patients.

Serum vitamin D concentrations were lower in smokers (51 nmol/L) than nonsmokers (64 nmol/L, p<0.02). Unfortunately, Dodington and colleagues do not report blood vitamin concentrations. Inflammation and production of reactive oxidative species are characteristic of periodontal disease.

This paper surely convinces me of the importance of maintaining circulating concentrations of antioxidant vitamins and omega-3 fatty acids to keep a healthy smile. Oh yes, and don’t smoke!
