What is an effect of using continuous wave CO2 lasers on soft tissue?

The use of continuous wave CO2 lasers on soft tissue typically results in a level of thermal damage that needs to be understood in the context of their interaction with biological tissues. While these lasers are very effective for ablation due to their ability to vaporize water contained in the soft tissue, they can also lead to significant thermal effects on surrounding tissues.

When the correct choice indicates that the tissues are "easily ablated" but suggests "severe carbonization," it refers to the tendency of CO2 lasers to produce intense heat during the ablation process, which can lead to carbonization of the tissue. This is a common outcome when soft tissues are exposed to high-energy light, and although the laser offers precision, the surrounding areas can experience unwanted thermal damage, including charring and carbonization. Therefore, the process results in a distinct contrast between effective tissue removal and potential detrimental thermal effects.

Understanding the characteristics of CO2 lasers helps clinicians utilize them effectively while being aware of the possible complications that arise from excessive thermal energy being transferred to adjacent tissues. This is essential in periodontal treatments where precision and tissue preservation are crucial.
