自从1960年Maiman发射出红宝石激光,1961年Javan发射氦氖激光以来,已近20年。各领域均在研究激光的应用和普及。口腔科领域内对激光的研究较晚,尚未应用于临床,但最近对激光的研究开始活跃。一、目前口腔科领域激光研究的成果 1)清除龋齿病灶及形成窝洞激光的特长之一是功率大,特别是脉冲激光可在千分之一秒,甚至十亿分之一秒(10~(-9))的超短时间内发出巨大功率。因黑色物质特别易吸收激光,因之用于除去龋蚀病灶及形成窝洞更为有利。用脉冲激光可在一瞬间即除去病灶,再照射几次,即可在很短时间内形成窝洞,且几乎无痛。但能在口腔内
It has been almost 20 years since Maiman launched a ruby laser in 1960 and Javan launched a helium-neon laser in 1961. Various fields are studying the application of laser and popularization. Laser research in the field of stomatology late, has not been applied to clinical, but the recent study of the laser began to become active. First, the current results of laser research in the field of dentistry 1) the removal of dental caries lesions and the formation of cavity laser is one of the great power, especially pulsed laser in the thousandth of a second, or even a billionth of a second (10 ~ (-9)) in a very short period of time issued a huge power. Because of the black material is particularly easy to absorb the laser, which is used to remove the lesion and cavities to form cavities more favorable. With pulsed laser in a flash that is to remove the lesion, and then irradiated several times, you can form cavities in a very short period of time, and almost no pain. But in the mouth
