Abstract

Since their appearance in 1960, lasers have been considered useful light sources for medical applications. Laser light is monochromatic, the bundle is parallel and can be directed and focussed, as a result of which very high energy densities can be achieved. Several applications in dentistry have been investigated over the past decades. This article describes the physics behind lasers, the characteristics of the laser beam and overviews the laser wavelengths currently used in dentistry. The different interactions between the laser beam and the target are explained.

摘要

自1960年出现以来，激光一直被视为医学应用中的有用光源。激光是单色的，光束是平行的，可以被引导和聚焦，因此可以实现非常高的能量密度。在过去几十年里，人们对激光在牙科领域的几种应用进行了研究。本文介绍了激光背后的物理学原理、激光束的特性，并概述了目前牙科中使用的激光波长。还解释了激光束与目标之间的不同相互作用。
