CARIES PREVENTION USING SHORT-PULSED CARBON DIOXIDE LASERS
LABORATORY BACKGROUND AND CLINICAL APPROACHES
First the presentation will give a basic understanding about how dental lasers can be of advantage in the dental practice. Then the pathway from the basic laboratory studies in laser caries prevention to successful clinical applications will be illustrated. It will be demonstrated why short-pulsed carbon dioxide (CO2) lasers are extremely successful and efficient in altering acid prone carbonated enamel, the type of enamel actually presented in the mouth, into much more acid resistant hydroxyapatite or even fluorapatite. Consequently, the first clinical study using this specific laser wavelength, which proved caries prevention around orthodontic brackets in vital teeth, will be explained. This study was followed by a major randomized, controlled, prospective, blinded clinical trial involving 20 participants over 12 months, demonstrating that caries prevention in molar fissures can be achieved. Finally, first results from a huge second randomized, blinded clinical trial preventing demineralization in occlusal pits and fissure with 60 participants using a 9.3μm laser will be provided.
At the completion of the course, participants will be able to:
1. Achieve a basic understanding of how dental lasers can help you in the dental office
2. Understand how short-pulsed CO2 9.6μm and 9.3μm laser irradiation renders enamel caries resistant, and how they also can be used for efficient hard and soft tissue cutting
3. Understand how randomized prospective clinical trials have shown the caries preventive effects of these short-pulsed CO2 lasers
