What is the main mechanism of action for Class IV lasers?

The primary mechanism of action for Class IV lasers revolves around their ability to stimulate cellular activity, which significantly enhances healing processes and reduces inflammation. When Class IV lasers are applied, they deliver specific wavelengths of light that penetrate tissues and are absorbed by cellular components, particularly by chromophores within the cells.

This absorption of light energy stimulates various biochemical processes, such as increased mitochondrial ATP production, which provides the energy necessary for cellular repair and regeneration. The increased energy availability leads to various physiological effects, such as improved circulation, reduced inflammation, and accelerated tissue healing. This is why the stimulation of cellular activity is regarded as the fundamental action of Class IV lasers, making it instrumental in therapeutic applications like pain relief and tissue repair in various medical and veterinary settings.
