Sensors for dentures could help lessen speech problems
Updated: 5/27/2008 2:00:15 PM

Dentures can be a bane for some wearers, affecting a person's speech and eating habits.

In a bid to tackle the problem, scientists in Grenoble, France, have developed dentures fitted with sensors to reveal the tongue's movement during speech.

It is hoped that this study could enable researchers to find a way to minimize the impact of dentures and braces on speech, the New Scientist reports.

Apparently, it is currently difficult to get a true sense of how much pressure the tongue exerts on the teeth when making specific sounds, such as a 'T'.

Earlier ways of measuring pressure were cumbersome and somewhat ineffectual, but the French team hoped that by hiding their sensors in dentures it would not impede the usual workings of the tongue.

The output of the sensors was transmitted to a computer via a wire running along the inside of the cheek, while the sounds the person made were recorded by a microphone.

According to the Baltimore Sun, around a quarter of Americans aged 60-plus no longer have their own teeth, leading many of them to opt for dentures.
