History of Dental Laser Use, Scientific Basis and Future Aspects
First, this presentation will give a short history about lasers in dentistry, how they work, and how lasers can be helpful in the daily dental office routines. Next, the pathway from the basic laboratory studies in laser caries prevention to successful, clinical applications for preventing caries in human teeth will be illustrated. It will be demonstrated why short-pulsed carbon dioxide (CO2) lasers are extremely efficient in altering acid prone carbonated enamel, the type of enamel actually presented in the mouth, into a more acid resistant hydroxyapatite or even fluorapatite. Clinical studies using this specific laser wavelength for caries prevention in vital teeth will be discussed. These includes a first study dealing with potential mineral loss around orthodontic brackets. Then two randomized, blinded clinical trials preventing demineralization in occlusal pits and fissure will be explained.
