Dental Lasers and Application Fields in Endodontics

Abstract

Introduction LASER (Light Amplification by Stimulated Emission of Radiation) was developed in 1960 by a scientist working for the Hughes Aircraft Corporation, Theodore Maiman, who proposed its mechanism based on the emitted beam coming from a ruby crystal (1).Lasers were tested for dental use first between 1970-1980, and laser devices such as carbon dioxide (CO 2 ) and neodymium:doped yttrium aluminum garnet (Nd:YAG) were considered suitable for hard dental tissues, while lasers were already in use for soft-tissue procedures in the middle of 1970s. Since then, many type of laser devices and applications have been used in dentistry, and new laser models and applications are still being created (2).The most common dental lasers in use today are erbium, Nd:YAG, diode, erbium, chromium doped: yttrium, scandium, gallium and garnet (Cr:YSGG), and CO 2 . Naturally, different types of lasers possess specific biological effects, are used in different procedures and, thus, are coupled with specific applicators. Nd:YAG LasersMarketed solely for dental use, these are the first true pulse lasers with a near infrared wavelength of 1064 nm (3). Primarily used for Öz 1971'de Weichman tarafından endodonti alanında ilk lazer uygulanmasının ardından, lazer teknolojisinin hızlı gelişimi ile yeni lazer cihazları ile ilgili çalışmalar hız kazanmıştır. Bu makalenin amacı, endodontide lazer uygulama alanlarıyla ilgili bilgileri güncellemek ve lazer cihazlarının avantaj ve kısıtlamaları hakkında bilgi vermektir.Since the first laser application in endodontics by Weichman in 1971, search for new laser devices is being proposed with the rapid development of laser technology. The purpose of this article is to update the information on laser application fields in endodontics and give information regarding the advantages and limitations of the laser devices.Received/Geliş Ta rihi :
