Lasers in Esthetic Dentistry
Lasers have been be used for various treatment in dentistry. Especially in recent years, the understanding of the clinical application of lasers has deepened, and lasers have come to be used in more complicated and difficult cases. The usage of lasers has made treatment easier, faster, and more reliable. In particular, treatment in the aesthetic area is often complicated and difficult because aesthetics are evaluated at the same time as their function. The treatment must be done under enough examinations and diagnosis. Since there are various types of lasers used, a good prognosis can be expected by selecting the appropriate device for each treatment. Since dental treatment targets teeth, gums, and bones, the key to success is an understanding of each tissue and the selection of laser device. Selecting the correct laser device and setting appropriate parameters for treatment lead to successful esthetic dentistry.
On-line: Clinical risk management in laser dentistry
Classification of laser equipment defined by IEC（International Electrotechnical Commission）is widely used. The classification is based on the degree of danger of the laser equipment to the human body. Care must be taken not to irradiate the human body with the laser beam, but if the benefits outweigh the profit and loss, the human body is irradiated with the laser. A typical irradiation to the human body with laser light is a medical practice. Medical laser devices have been used for treatment and examination. Many laser devices have also been used in dentistry. Now the laser treatment has become commonplace in dentistry, it is necessary to pay attention to its safe use. This lecture will discuss safety controls and possible accidents and complications that can occur when using laser equipment in dentistry.
