Tooth decay detected by laser and light systems

A growing body of research shows the light-based devices are highly sensitive. A recent study found one device caught 93 percent of early caries, the dental term for tooth decay, compared with 27 per cent for X-rays. But some scientists warn the machines could result in overtreatment — as early decay may not need a filling.” To view more on this article or other articles please click here.  Tooth decay detected by laser and light systems
