" Dental Care with a Difference " ® SMOKING, SLEEP AFFECT PERIODONTAL HEALTHA study in the May issue of Journal of Periodontology has identified smoking and sleep as the lifestyle factors that have the most impact on periodontal health.
Researchers at the University of Osaka in Japan followed a group of 219 factory workers in Japan from 1999 to 2003 to evaluate the effect of different lifestyle factors on the progression of periodontal disease. They evaluated each worker on the following lifestyle factors: physical exercise, alcohol consumption, tobacco use, hours of sleep, nutritional balance, mental stress, hours worked and eating breakfast.
They found that the lifestyle factor that had the greatest independent effect on the progression of periodontal disease was smoking. More than 41 percent of study participants who exhibited periodontal disease progression from 1999 to 2003 were current smokers.
They identified lack of sleep as the second most influential factor in the progression of periodontal disease. They found that participants who received seven to eight hours of sleep a night exhibited less periodontal disease progression than did those who received six hours of sleep a night or less.
"From our study, we can speculate that shortage of sleep can impair the body’s immune response, which may lead to the progression of diseases such as periodontal disease," said corresponding author Dr. Muneo Tanaka, Department of Preventive Dentistry, Osaka University Graduate School of Dentistry.
Researchers also found that high stress levels and daily alcohol consumption significantly affected periodontal disease progression.
"Simple lifestyle changes, such as getting more sleep, may help patients improve or protect their oral health," said Dr. Preston D. Miller, president of the American Academy of Periodontology. "It is important to keep this in mind as the body of evidence linking oral disease with systemic diseases continues to grow, because, ultimately, these lifestyle factors might impact a patient’s overall health."
