A study performed at Osaka University Hospital in Japan compared four groups of patients based on their brushing frequency and whether they were at risk for developing cardiovascular diseases (CVDs).
• Group MN brushed twice a day, Group Night once a night, and Group M once after waking up; Group None did not brush their teeth at all.
• The researchers evaluated blood samples, smoking histories, and follow-up results of the 1,675 participants.
• After evaluating variables like dental pocket depth, tooth mobility index, and BNP levels, the researchers found that Groups MN and Night had higher survival rates than Group None.
• Furthermore, individuals who did not brush their teeth at night may have done so due to poor oral hygiene or lifestyle habits.
• The findings reiterate that while brushing teeth before breakfast is necessary for good oral health, brushing teeth at night before going to bed is even more important to prevent CVDs.
