Participants underwent a routine medical examination between 2003 and 2004 and information was collected on height, weight, laboratory tests, illnesses, Travel, oral health, and oral hygiene behaviours.
During a median follow-up of 10.5 years, three percent of participants developed atrial fibrillation and around five per cent developed heart failure.
Tooth brushing three or more times a day was associated with a 10 percent lower risk of atrial fibrillation and a 12 percent lower risk of heart failure during the follow up.
The findings were independent of a number of factors including age, sex, socioeconomic status, regular exercise, alcohol consumption, body mass index, and conditions such as hypertension.
