Which laser is often used in periodontal therapy?

In periodontal therapy, various types of lasers can be utilized effectively, making "All of the above" the correct choice. Each of these lasers—Nd:YAG, Er:YAG, and diode lasers—has specific applications and benefits in the context of treating periodontal disease.

The Nd:YAG laser is commonly used for surgical procedures due to its ability to penetrate soft tissues while minimizing thermal damage. This property makes it suitable for osseous surgery and soft tissue management in periodontal therapy.

The Er:YAG laser is particularly effective for hard tissue procedures because it can remove bone and dental hard tissues with precision. Its ability to ablate tissue with minimal heat makes it a good choice for procedures that require care to avoid damage to surrounding structures.

Diode lasers are versatile and often used in gingival procedures. They are favored for their efficacy in soft tissue procedures, such as gingivectomy and treatment of periodontal pockets, due to their ability to coagulate tissue and reduce bleeding.

Overall, the use of all three types of lasers in periodontal therapy demonstrates the range of advanced techniques available to enhance treatment outcomes while prioritizing patient comfort and recovery.
