LASERS WAVELENGTH USED IN DENTISTRY Argon Lasers This laser has an active medium of ionized argon gas, energized by a high current electrical discharge, and the laser light is delivered fiber-optically in continuous wave and gated pulsed modes. There are two emission argon laser wavelengths used in dentistry: 488 nm (blue) and 514 nm (blue green).
Research supports the use of the argon laser in dentistry. Used at powers of 250 mW +/- 50 mW for 10 seconds per increment, the argon laser provides good curing of light-activated restorative ...
Argon. The argon laser operates at a wavelength of 457 to 502 nanometers, using a pulsed or continuous waveform. and tooth bleaching. In addition, this laser has a number of soft-tissue applications, including gingival troughing, esthetic contouring of gingiva, treatment of oral ulcers, frenectomy and gingivectomy.
used in medicine and dentistry. “Soft” lasers provide cold (athermal) low energy at wavelengths believed to stim ulate circulation and cellular activity.1 Experimentally, these lasers have been used to promote healing and reduce inflammation, edema and pain. “Hard” lasers have been used extensively for surgical applications and are the
The CO 2 laser has been used for intraoral procedures since the 1960s and millions of CO 2 laser procedures have been performed with Luxar-LightScalpel flexible fibers since 1991 to date. A great deal of peer-reviewed literature advocates the use of CO 2 dental lasers in soft tissue dentistry due to their most important attribute: the WAVELENGTH.
on by using dental radiography or laser-assisted diagno-sis of dental decay.6 In the last few years, new tech-niques for the prevention of caries lesions have been developed and many investigations related to the appli-cations of lasers in the field of pediatric dentistry have been conducted. DIAGNOSIS Using the argon laser with a wavelength of ...
The Academy of Laser Dentistry has great educational opportunities and lectures, and I quickly gained knowledge in laser dentistry. The argon laser is a very smart light, and I soon learned that I could really help my clients with their deep intrinsic stains. At this particular juncture, we still use a bleaching gel to interact with the laser ...
The fields of application and efficiency of dental lasers depend on the laser beam parameters determined by the laser type. The argon laser (488 nm and 514 nm wavelength). The laser radiation is well absorbed by melanin and hemoglobin. A wavelength of 488 nm is similar to that of polymerization lamps. At the same time, the rate and degree of ...
Because the technology in the dental office is still new, cost of the argon laser curing unit is a deterrent to its acquisition. Depending on the manufacturer, portable argon curing lasers range from $12,000 to $20,000, and central installation may incur additional expenses.
When appropriate, comparisons between the argon laser and other treatment methods were made. It was concluded that the argon laser has applicability in composite resin placement, in enamel and dentin bonding procedures, in preventive dental therapies, and in endodontic procedures.

The argon laser is an alternative light source that can be used for the photopolymerization of resin-based dental materials and for tooth bleaching. The argon laser emits specific laser lines with wavelengths that correspond to the absorption peak of camphoroquinone, the initiator of polymerization for the adequate photocuring of resin composite.

ARGON LASERS. Argon lasers use a gas medium and produce wavelengths between 488 nm and 514 nm. This beam is in the visible light spectrum (blue and blue green). This wavelength is poorly absorbed in enamel and dentin. Argon lasers were traditionally used for caries detection.

Advantages of Argon ion laser. The width of the spectrum of Argon ion laser is large i.e. it emits multiple wavelengths. The output of the Argon laser is high as compared to the output of the He-Ne laser. The argon laser is a high-gain system. The divergence of the Argon laser is very small.
The use of the argon laser in dentistry has been proposed for polymerization of resin materials and bleaching of enamel.11,12 It has been shown to be safe for the intraoral polymerization of composite materials at low fluence levels.13 Recent studies suggest that the argon laser can be used to prevent enamel decalcifica-

Dr. Sun offers these Dental Lasers and their related procedures: • Argon – laser teeth whitening. • Ultra Speed CO2 – soft tissue surgery like an implant, cosmetic gum contouring, a frenectomy or other oral tissue surgeries. • Dual Wavelength Surgical Argon – tooth whitening, soft tissue surgeries like gingivoplasty, frenectomy and ...
Approaching lasers from both clinical and scientific standpoints, this first-of-its-kind book is a comprehensive resource on the use of lasers in dentistry today. The text, organized in four sections, offers readers an up-to-date overview of the subject. Part I is a foundation providing basic information on how lasers interact with oral tissues. Part II addresses practical considerations, such ...
The argon laser produces high-intensity visible blue light (488 nm), which can initiate photopolymerization of light-cured dental restorative materials. The temperature increase at the level of the dental pulp is much lower with the argon laser cure than when a conventional quartz tungsten halogen lamp unit is used.
Lasers 101 “Laser” is an acronym that stands for “light amplification by the stimulated emission of radiation.” The laser device produces light energy, concentrated into a very narrow beam that is directed at the oral tissue. Depending on the type of laser used, the tissue will then undergo a particular reaction. In dentistry, lasers ...
