Researchers find that drinking coffee, which is a source of antioxidants, appears to curb tooth loss due to gum disease. “We found that coffee consumption did not have an adverse effect on periodontal health, and, instead, may have protective effects against periodontal disease.” says Nathan Ng, lead author and recent graduate of Boston University’s School of Dental Medicine. Coffee consumption was associated with a small but statistically significant reduction in number of teeth with periodontal bone loss. The researchers conclude that coffee consumption may be protective against periodontal bone loss in adult men—the group examined in the study. “This is the first long-term study of its kind that has investigated the association between coffee consumption and periodontal disease in humans,” Ng adds. The research appears in theJournal of Periodontology. Researchers looked at data collected from 1,152 men in the US Department of Veterans Affairs Dental Longitudinal Study (DLS) during triennial dental visits between 1968 and 1998. The DLS is a prospective study of the oral health of medically healthy male veterans that began in 1968. The men were 98 percent non-Hispanic white males ages 26 to 84 at the start. Information about coffee intake was self-reported by the participants. Researchers controlled for risk factors such as alcohol consumption, education, diabetes status, body mass index, smoking, frequency of brushing and flossing, and recent periodontal treatment or dental cleanings. Researchers suggest exploring their findings in a more diverse study population in the future. Source: Bu.edu
