It is pumped by flashlamp, and is also used in dermatology for removal of wrinkles, acne, scars, and pigmented lesions, agespots, sun-spots and freckles, complexion improvement and reducing stretch marks (parameters: 80 mJ, 5 or 10 ms length of pulse, 1 Hz). Laser irradiation produced a thin affected layer (5.7 μm in depth) with a superficial microstructure on the cementum. The Erbium YAG Laser is a clinically proven laser procedure for skin resurfacing, and also for the successful management of scars and wrinkles. Each of the 200-μsec pulses actually consists of a train of about 20 shorter pulses (typically 1 μsec long). The test group displayed a greater tendency for CAL gain, although this did not prove to be statistically significant. Additional mechanical treatment to remove the superficially changed layer, using acid etching or hand instruments, is recommended to enhance periodontal tissue healing.159,200, J. Pašta, in Lasers for Medical Applications, 2013. The so-called Erbium:YAG laser (synonym: Er:YAG laser), a solid-state laser, is particularly suitable for use in dentistry.It Although similar in wavelength, these two erbium lasers are slightly different in absorption coefficient, extinction length, and other wavelength-dependent parameters. Side effects from Er:YAG laser treatment are usually minor and may include: For selected skin conditions, Er:YAG laser treatment offers: See smartphone apps to check your skin. Erbium:YAG laser treatments have a lower risk of side effects, including hyperpigmentation or skin bleaching, compared to CO 2 treatments. Please submit your photos of this topic for inclusion. Maruyama et al.199 compared erbium laser irradiation alone with irradiation followed by chemical and/or mechanical conditioning (using tetracycline, EDTA gel, or minocycline paste). » Thermal rise in the superficial tissue layers is minimal and even less with concurrent water spray during the laser procedure. Apr 1 2003; 111(4): 1524–9; discussion 1530–2. These wavelengths are used preferably on hard tissue but also can be used on soft tissue. Degranulation and root debridement were effectively accomplished with the Er:YAG laser without major thermal damage and somewhat faster than with a curette. This however has not replaced the use of fractional CO2, which is still the gold standard today for treating acne scars. Their attractiveness resides in the wavelengths generated. Erbium:YAG lasers utilize the chromophore water to cause the greatest amount of vaporization possible to effectively treat and remove unwanted skin blemishes, both superficial and deep. The Erbium YAG Laser has been introduced as the next step in laser resurfacing and offers the benefits of less pain during treatment and recovery along with significantly faster healing times than any other resurfacing laser!

In addition, the 2.9 μm radiation of Er:YAG lasers is also absorbed by hydroxyapatite (see Fig. Author: Anoma Ranaweera B.V.Sc; PhD (Clinical Biochemistry, University of Liverpool, UK); Copy Editor: Clare Morrison; Chief Editor: Dr Amanda Oakley, Dermatologist, Hamilton, New Zealand, March 2014. One nanometre equals one billionth of a metre. Factors that increase difficulty of SRP are complex root anatomy, interproximal areas, furcation areas, the cementoenamel junction, multirooted teeth, and distal sites of molars, all of which often are associated with residual calculus and plaque after treatment. The operation of the Er: YAG laser at room temperature was discovered in 1975. Although Nd:YAG lasers have FDA clearance for ablating first-degree caries in enamel, the process is extremely slow and tedious and has essentially been replaced by the erbium family of lasers. Er:YAG laser sclerostomy (optical microscope record, energy 270 mJ, length of pulse 250 μs, three pulses applied). Because the erbium laser energy is highly absorbed in water and other hydrous organic contents, when irradiating tissues with high water content, only a superficial interaction occurs. The erbium provides the laser activity in the crystal. Collagen shrinking is reduced with the erbium, resulting in decreased effect on rhytids. Cole RP, Widdowson D, Moore JC. Lasers work by emitting a wavelength of high energy light, which when focused on a certain skin condition will create heat and destroy diseased cells. Studies tend to show that fractional ablative laser erbium YAG and non-ablative laser erbium glass are effective and safe for the treatment of skin spots and acne, but most of these studies do not provide insight into the long-term efficacy and safety profiles of these devices when used for these cosmetic indications. For the other active media in this region (Cr:Tm:Er:YAG, Er:Cr:YSGG with the generated wavelengths 2697 nm and 2796 nm, respectively) the absorption in water is not on the maximum of the curve (which gives the possibility of delivering this radiation by special low-hydroxyl-fused-silica fibers), but still it is very high.
