Wanna know about the "Genuine Smile"!!
DentalProfessional
James Doundoulakis is a connoisseur of smiles.
"There's an infinite number of tooth colors - but there are only 20
families of smiles," the Harvard-trained prosthodontist said, noting
that contemporary understanding of the physiology of the smile owes
much to a 19th-century French neurologist, Guillaume Duchenne. Using
electrical voltage on cadavers, he discovered that 10 of the face's 100
muscles were involved in producing smiles.
For his efforts, Duchenne was honored by having a smile named after
him. The Duchenne Smile is what dentists call a "genuine smile" because
its possessor fully employs the zygomaticus muscle that connects the
corners of the mouth with the cheekbone.
Is the Duchenne Smile the "perfect smile"?
"That depends on the person's perception of just what a smile is," Dr.
Doundoulakis said. "Some people like their smiles to be bold and sharp,
others want their teeth to display an intense pointy smile.
"Me? I like soft smiles," says Dr. Doundoulakis.
