摘要

Without regular brushing and floss-ing, teeth accumulate bacterial films that secrete acid and cause cavities (see adjacent article). But sometimes even these good habits are insufficient to shift such films, and a chemical called chlorhexidine has to be deployed as well, in the form of a mouthwash. Chlorhexidine, however, stains teeth and affects people's sense of taste, so an alternative would be welcome. And Victoria Moreno-Arribas of the Institute of Food Science Research in Madrid believes she may have one: a derivative of red wine. Dr Moreno-Arribas knew from previous work that red wine has antimicrobial properties, but she could find few studies which looked at whether it attacks dental biofilms specifically. To rectify that, she and her colleagues grew five troublesome oral bacteria, Actinomyces oris, Fusobacte-rium nucleatum. Streptococcus mutans, Streptococcus oralis and Veillonella dispar, on discs of hydroxyapatite, the main component of dental enamel. They fed the bugs by dipping the discs into solutions of sugar mixed with saliva collected from volunteers, who spent several hours spitting into jars. The results have just been published in the Journal of Agricultural and Food Chemistry.
