Perfect Looking Teeth

A new measuring technique determines the effect of dental care products and helps  them so they polish the rough tooth surfaces until they are perfectly smooth, while preserving the tooth enamel. The tooth surface wears down and gets uneven – and the problem is that dental plaque adheres particularly well to a rough surface. Dentists therefore offer professional cleaning services, removing plaque and discoloration with abrasive prophylactic pastes. This renders the tooth surface beautifully smooth, making it difficult for bacteria to gain a foothold. Yet there is a risk that the polishing treatment will also grind away precious tooth enamel and dentin at the exposed necks of teeth. The manufacturers therefore have to find the happy medium when developing their prophylactic pastes: The pastes should be just abrasive enough to remove superficial discoloration and plaque, but preferably not wear down the tooth enamel. Until now, scientists lacked any realistic objective measuring techniques to assess tooth abrasion caused by chewing and by the effect of toothpastes. A leading manufacturer of dental hygiene products asked the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, one of whose specialties is the analysis and visualization of surface roughness, to help them develop new […]
