In the present short communication, we would like to suggest a possible mechanism for the healing effects exerted by the erbium:yttrium-aluminum-garnet (Er:YAG) laser with a wavelength of 2940 nm (which surprisingly is the exact vibrational OH stretch frequency of water).

Article Synopsis
- * These lasers are known for their ability to cause initial collagen contraction and thermal damage, which are important factors in the wound healing process.
- * The authors propose a new mechanism to explain how the Er:YAG laser promotes healing, though the exact processes behind its cosmetic benefits remain unclear.
In recent years, much research has been done in the field of non-ablative skin rejuvenation. This comes as a response to the continuous demand for a simple method of treating rhytides, UV exposure, and acne scars. Numerous researches involve visible light-pulsed systems (20-30 J/cm(2)).

Objective: The aim of the present study was to show that rapid wound repair following Er:YAG treatment and its bactericidal effect can also be related to reactive oxygen species (ROS) generation in irradiated tissue.
Background Data: The Er:YAG laser with a wavelength of 2,940 nm (corresponding to the vibrational OH stretch frequency of water) is of great value in dental medicine, owing to its dual ability to ablate soft and hard tissues with minimal damage to surrounding structures. The relatively rapid postoperative healing time seen after ablation of the gingiva is attributed to the very narrow zone of thermal disruption.
