What is one of the main advantages of using lasers in periodontal treatment?

Using lasers in periodontal treatment is beneficial primarily due to their ability to reduce collateral thermal damage. This advantage arises from the precision with which lasers can target specific tissues, allowing for surgical procedures that minimize injury to surrounding healthy tissues. Traditional surgical techniques often result in a broader area of thermal damage, which can complicate healing and lead to discomfort for the patient.

The use of lasers allows for more precise cuts and vaporization of oral tissues, leading to less bleeding and inflammation. Consequently, the healing process can often be quicker and less painful compared to methods that employ conventional instruments. The reduction of collateral thermal damage is critical because it decreases the potential for complications such as prolonged recovery time and unnecessary tissue necrosis, making laser treatment particularly advantageous in periodontal therapy.

In this context, it's important to note that the other options do not reflect the benefits associated with laser usage in periodontal procedures. For instance, increased healing time, higher rates of pain for patients, and increased risk of infection contradict the fundamental goals of periodontal treatment, which aim to promote healing, minimize discomfort, and reduce risks associated with surgical interventions.
