People and neat white teeth is often considered more healthy, clean and attractive than those whose teeth are dull or yellowish. But so far no one knows what the reason behind it because it is not necessarily white teeth from dental health standards.
A group of British researchers who tried to find an explanation about it was revealed that the teeth in humans that is similar to the peacock's tail as one marker of genetic quality and health that is designed to attract or get a pair.
For this study, researchers from the University of Leeds and the University of Central Lanchasire teeth took the photos of the model which then changed the color of their teeth and were given a digital space. The three colors chosen for the teeth are brownish yellow, white, healthy and flashy white that could only be obtained by bleaching or whitening.
Then the pictures were shown in 150 young male and female respondents and the researchers asked respondents to rate how attractive models in the photo.
The result is not surprising, photo model unpopular with yellow teeth, as well as a photo model with teeth that were spaced rather wide because it is considered less attractive. Even so, researchers found that most respondents consider the condition of her teeth is very important.
"When men see women and vice versa when the woman saw the man, there is a very strong effect was between them. Men always think women's gear is one of her own attractiveness, but caring for teeth to win the competition among fellow women," said researchers from Leeds University , Colin Hendrie.
Dr. Hendrie also believe that women's gear can be used to help provide an assessment of the age and how far women concerned with menopause.
"The condition of the teeth also contain a hint of illness in children, diet and suffered a number of genetic disorders," he added of zeenews, Friday (08/03/2012).
