Although continuous tooth used for chewing, but in fact our teeth become stronger every day. The researchers likened this ability by the microstructure such as "wicker basket" contained in human tooth enamel.
"It is still a mystery, how teeth can be as strong as that," said Brian Lawn of the National Institute of Standards and Technology was quoted by the Times of India.
In this study, the researchers took samples of human teeth, beavers, and some other animal teeth. Then treat it like a piece of iron teeth and practice scenarios such as biting movements.
Lawn explained, this study aims to determine how strong your teeth can last before it becomes damaged. The research team found that the microstructure is shaped like a "wicker basket" on the tooth enamel was arrested cracks formed and potentially damaging, and spread across the surface of the tooth.
"This finding explains why when the dentist examined the teeth of adults, they can find out if the teeth are there a lot of cracks. Though the tooth is still intact, "said Lawn.
Tooth enamel thickness and size can also affect how strong the teeth can chew food.
This research was beneficial to the anthropologist. Because they can use as reference information on the enamel of teeth in the study of the evolution of primates and other animals in general. Enamel structure can be utilized to develop a similar substance, as well as for replacement dentures.
