The carbon dioxide laser is used in the oral cavity for a variety of procedures. Although the procedures may not involve the teeth directly, precaution should be exercised to preserve their integrity. The results of this study indicate that the most limiting parameter for oral use of the CO2 laser is damage to the enamel surface, which could be inflicted with as little as 5 W for 0.2 second and a 1 mm beam. Care should be exercised to prevent inadvertent damage to the surface enamel of teeth even at very low energy levels.
二氧化碳激光在口腔中用于多种手术。尽管这些手术可能不直接涉及牙齿，但应采取预防措施以保持牙齿的完整性。本研究结果表明，二氧化碳激光在口腔应用中最具限制的参数是对牙釉质表面的损伤，使用1毫米光束，仅5瓦功率照射0.2秒就可能造成这种损伤。即使在非常低的能量水平下，也应小心防止意外损伤牙齿表面的牙釉质。
