What do we achieve with a good dental hygiene?
Most of the people know that poor dental hygiene can lead to tooth decay, bad breath and gum disease, but not brushing your teeth could also lead to more serious diseases.
Here we are going to investigate what other - perhaps unexpected - health conditions are affected by poor dental health.
In 2010, researchers from New York University (NYU) concluded that there is a link between gum inflammation and Alzheimer's disease, after reviewing 20 years of data on the association.
However, the number of people whom participated in the NYU study was quite small. The researchers analyzed data from 152 subjects enrolled in the Glostrop Aging Study - a study looking at psychological, medical and oral health in Danish men and women. The study spanned a 20-year period and ended in 1984, when the subjects were all over the age of 70.
Comparing cognitive function at ages 50 and 70, the NYU team came to the conclusion that gum disease at the age of 70 was strongly associated with low scores for cognitive function.
Study participants were nine times more likely to have a score in the lower range of the cognitive test - the "digit symbol test" (DST) - if they had inflammation of the gums.
On the other hand this study took into account potentially confounding factors like obesity, cigarette smoking and tooth loss unrelated to gum inflammation, there was still a strong association between low DST score and gum inflammation.
In 2013, UK-based researchers from the University of Central Lancashire (UCLan) built on the findings of this study, by comparing brain samples from 10 living patients with Alzheimer's with 10 brain samples from people who did not have the disease.
