Comparative Efficacy of Laser Systems and Fluoride in Managing Dentinal Hypersensitivity: RCT

The lasers emit light energy in the infrared and visible spectrum, which is fundamentally different from ionizing radiation (like X-rays or gamma rays) that can damage DNA. Dental lasers work through photobiomodulation and thermal effects, not through radiation exposure.

Non-ionizing radiation or more accurately as optical energy devices, not ionizing radiation.
