Polyphenols, oral health and disease: A review.
Consistent, well-designed, epidemiological, animal and in vitro studies directly and indirectly support the preventive polyphenol effect against oral cancer with good evidence.

Anti-cariogenic effects of polyphenols from plant stimulant beverages (cocoa, coffee, tea).
Polyphenols occurring in cocoa, coffee and tea can have a role in the prevention of cariogenic processes, due to their antibacterial action. Cocoa polyphenol pentamers significantly reduce biofilm formation and acid production by Streptococcus mutans and S. sanguinis.
The Role of Polyphenolic Antioxidants in Health, Disease, and Aging
Polyphenolic antioxidants from dietary sources may help lower the incidence of certain cancers, cardiovascular and neurodegenerative diseases, and DNA damage and even may have antiaging properties. This review critically examines polyphenolic antioxidants, such as flavonoids, curcumene, and resveratrol in health, disease, and aging with the hope that a better understanding of the many mechanisms involved ...

Vitamin and Mineral Supplements
Vitamin and mineral supplements are designed to treat and prevent deficiency syndromes and promote health. Consumers frequently misuse them, as they are guided by the belief that these supplements will prevent diseases and cure symptoms. Scientific evidence demonstrates their limited usefulness in systemic disease prevention or treatment. The author reviews demonstrated benefits in select diseases.
Dental procedures and materials can increase free radicals
The substances used in aesthetic procedures, such as bleaching or other whitening agents, can cause a dramatic increase in the level of free radicals in oral tissues.
Corrosion of machined titanium dental implants under inflammatory conditions.
The results suggest that inflammatory stress and hyperglycemia may increase the corrosion of dental endosseous titanium-based implants, but that longer, more aggressive electrochemical conditions may be necessary to fully assess these effects.
Effect of toothbrushing on elemental release from dental casting alloys.
Under the conditions of this study, toothbrushing increased the elemental release from dental casting alloys.
Effect of toothbrushing on the toxicity of casting alloys.
Brushing dental casting alloys may increase their cytotoxicity in vitro, but the increase depends heavily on the alloy type and brushing condition.
Effect of pH on element release from dental casting alloys
Transient exposure of casting alloys to an acidic oral environment is likely to significantly increase elemental release from Ni-based alloys, but not from high-noble or noble alloys. Elemental release is important because it plays a significant role in alloy biocompatibility.
Green tea polyphenol causes differential oxidative environments in tumor versus normal epithelial cells.
Pathways activated by GTPPs or EGCG in normal epithelial versus tumor cells create different oxidative environments, favoring either normal cell survival or tumor cell destruction. This finding may lead to applications of naturally occurring polyphenols to enhance the effectiveness of chemo/radiation therapy to promote cancer cell death while protecting normal cells.
