Laser technology has become an essential tool in modern dental practice due to its precision, safety, and effectiveness in various procedures. However, it is important to note that lasers also have their disadvantages. When deciding to use a laser, it is crucial to match the wavelength, power, and energy density to the target tissue absorptive characteristics to ensure the best possible treatment outcome. Dental surgeons or laser dentists must be knowledgeable about laser physics and laser-tissue interactions at different wavelengths to prevent hazardous damage to the eyes and skin of both the surgeon's assistants and patients. Failure to limit the extent of the laser's lateral heat conduction by an untrained clinician can cause a conduction burn that extends well beyond the laser surgical site, which could have disastrous consequences. This article reviews the safety measures that should be taken to avoid the hazards associated with using lasers in dentistry.
