Which of the following statements is true regarding laser operators?

The statement that only certified professionals should operate lasers is true because laser technology in dental procedures involves understanding the specific features, safety protocols, and effective usage of the equipment. It is essential for operators to have adequate training to prevent harm to both the patient and themselves, as well as to ensure the lasers are used effectively for the intended procedures.

Certified professionals, who have undergone proper training and education about lasers, can comprehend the physics of laser operation, tissue interaction, and safety measures necessary for their application in dentistry. This requirement aims to adhere to best practices within dental settings, where errors could lead to serious complications.

In contrast, the other statements suggest that anyone could potentially operate lasers or that basic training is unnecessary based on the device's settings. Such perspectives overlook the complexities and risks associated with operating laser technology in a clinical environment.
