Abstract
Five devices were tested for the amount of optical radiation they emitted. Recommended values can be exceeded with a workload of 17 to 81 applications in any 167-minute period. Some procedures, such as close viewing distances, direct view applications, and treating the anterior teeth may increase the exposure to the user.Mesh：
