The article discusses the science behind dental lasers and their potential applications across various dental procedures. It provides an overview of the theoretic background, including the principle of stimulated-emission introduced by Einstein and Maiman. The article also touches on the importance of thermal control when using lasers in dental treatments to prevent damage to surrounding tissues. While it notes the increasing interest in laser applications in areas like caries treatment, pediatric dentistry, and endodontics, the article stops short of drawing definitive conclusions, instead presenting an overview of current practices and ongoing exploration in this area.
