Association of Cigarette Smoking With Superoxide Dismutase Enzyme Levels in Subjects With Chronic Periodontitis
There was a progressive reduction in salivary antioxidant levels from healthy non-smokers to light smokers to heavy smokers.

Relationship Between Periodontal Condition and Plasma Reactive Oxygen Metabolites in Patients in the Maintenance Phase of Periodontal Treatment
A positive association was found between plasma oxidative status and periodontal attachment in patients in the maintenance phase of periodontal therapy. A systemic increase in oxidative stress may influence the rate of progression of periodontal disease.
Effects of Ethanol Consumption on Periodontal Inflammation in Rats
Studies suggest a correlation between ethanol consumption and periodontal disease. We hypothesized that elevated levels of blood reactive oxygen species following ethanol consumption may increase inflammation in periodontal tissue. Results suggest that chronic alcohol consumption increased periodontal inflammation, oxidative damage, and TNF-? production and had an additive effect on polymorphonuclear leukocyte infiltration and gingival oxidative ...

Periodontal diseases
Periodontitis results in loss of connective tissue and bone support and is a major cause of tooth loss in adults. In addition to pathogenic microorganisms in the biofilm, genetic and environmental factors, especially tobacco use, contribute to the cause of these diseases. Common forms of periodontal disease have been associated with adverse pregnancy outcomes, cardiovascular ... Read more
Toothbrushing, inflammation, and risk of cardiovascular disease: results from Scottish Health Survey
Poor oral hygiene is associated with higher levels of risk of cardiovascular disease and low grade inflammation, though the causal nature of the association is yet to be determined.
Antioxidants Counteract Nicotine and Promote Migration via RacGTP in Oral Fibroblast Cells
Smoking is associated with increased risk for oral health and dental problems. The aim of this study is to address the hypothesis that nicotine impairs wound healing by increasing reactive oxygen species (ROS) and inhibiting cell migration and that antioxidants (AOs) may counteract nicotine effects
Why Green Tea Strengthens Your Teeth
It's thought that naturally occurring substances in green tea have bacteriocidal effects helping to kill mouth bacteria and ward off tooth decay and gum disease.
Dental Health: Vitamins For Dental Health
Gingivitis is a form of periodontal disease defined as chronic inflammation of the gums. Infection invades the tissues of the gums and the periodontal ligaments and even the alveolar bone where the teeth attach. One of the most proven ways to protect your gums from periodontal disease is to use vitamin C supplements. Vitamin C ... Read more
An introduction to free radical biochemistry
Free radicals are chemical species possessing an unpaired electron that can be considered as fragments of molecules and which are generally very reactive. They are produced continuously in cells either as accidental by-products of metabolism or deliberately during, for example, phagocytosis. The most important reactants in free radical biochemistry in aerobic cells are oxygen and ... Read more
Ongoing Study - linking treatment of Periodontal infections to heart disease - Phase II
Epidemiological studies indicate that individuals with severe periodontal disease have significantly increased risk for cardiovascular disease. Periodontal disease, a chronic bacterial infection of the gums, is associated with recurrent bacteremia and a state of systemic inflammation that may convert endothelial cells to a pro-atherogenic phenotype with increased expression of inflammatory factors and loss of the ...
