What laser is appropriate for decay removal in a class V lesion?

The appropriate laser for decay removal in a class V lesion is the 9300-nm CO2 laser. This type of laser is well-suited for soft tissue procedures due to its high water absorption, allowing it to effectively remove decayed tissue while minimizing damage to the surrounding healthy structure. The specific wavelength of the CO2 laser penetrates soft tissue effectively, making it ideal for this type of dental application.

Moreover, a class V lesion typically involves the gingival margins, and the CO2 laser's ability to precisely ablate soft tissue while also providing hemostatic effects makes it advantageous in managing such lesions. Its versatility in soft tissue procedures underscores its appropriateness for this particular dental context. In contrast, other lasers might either not penetrate as effectively or may not provide the desired outcomes in soft tissue interactions that the CO2 laser offers.
