How does the laser interact with tissue during Laser Assisted Periodontal Therapy?

In Laser Assisted Periodontal Therapy, the laser has a specific interaction with tissue that focuses on stimulating healing through selective tissue interaction. This method utilizes the principles of photobiomodulation, where the laser light is absorbed by specific cellular chromophores, leading to a series of biological responses.

When the laser is applied, it can promote increased circulation, enhance cellular metabolism, and stimulate the proliferation of fibroblasts and other important cells in the healing process. This selective interaction allows for treatment that does not indiscriminately damage surrounding healthy tissue, which is crucial in periodontal therapy where the goal is to preserve as much healthy gum and bone tissue as possible.

While the other options involve methods like cauterization or vaporization, they do not align with the primary modalities and benefits provided by lasers in this context, which focus more on promoting healing rather than destructively altering tissue. The approach seeks to minimize trauma and optimize recovery, making selective tissue interaction the cornerstone of effective laser therapy in this field.
