Male coffee drinkers may have reduced risk of periodontal disease

BOSTON, Mass., USA: New research has indicated that coffee consumption may be protective against periodontal bone loss. In a study of over 1,000 dentate males, researchers found no evidence that coffee consumption was harmful to periodontal health. However, they found that men with a higher coffee consumption had fewer teeth affected by periodontal bone loss than did participants who drank less coffee.

In order to determine whether antioxidants or other anti-inflammatory components of coffee could benefit oral health, researchers at the Boston University Henry M. Goldman School of Dental Medicine studied the health data of 1,152 dentate males, who were originally enrolled in the Department of Veterans Affairs Dental Longitudinal Study. This prospective study, which was conducted between 1968 and 1998, was designed to assess the oral health of healthy white men between the ages of 26 and 84 when recruited for the study. The participants underwent dental checkups every three years over the study period.

"We found that coffee consumption did not have an adverse effect on periodontal health, and, instead, may have protective effects against periodontal disease," said lead author Nathan Ng from the dental school.

Based on the participants' self-reported information on individual coffee intake, the researchers observed that higher coffee consumption was associated with a small but significant reduction in the number of teeth with periodontal bone loss.

The study, titled "Coffee Consumption and Periodontal Disease in Males," was published in the August issue of the Journal of Periodontology.
