What percentage of light is typically absorbed in the treated area during laser therapy?

In laser therapy, particularly Class IV laser therapy, the percentage of light absorbed in the treated area is essential for understanding the effectiveness of the treatment. It is known that during laser applications, a significant amount of the light energy interacts with the tissue.

The correct range of 20-40% absorbed light indicates an optimal amount of energy penetration into the tissues, which is crucial for achieving therapeutic effects. This range allows for sufficient stimulation of cellular metabolism and healing processes without causing excessive heat or damage to the surrounding tissues. The absorbed light energy primarily contributes to photobiomodulation, which promotes tissue repair, reduces inflammation, and alleviates pain.

Understanding this absorption percentage is vital for clinicians as it allows them to adjust their treatment protocols based on the specific conditions being treated, patient responses, and the type of tissue being targeted. Effective laser therapy requires knowledge of how much energy is absorbed to ensure that treatment is both safe and effective, and the range of 20-40% fits well within those clinical applications.
