text: The laser surgery for dermatology often bypass the skin surface. The principle of laser surgery for dermatologic problem is based on SPTL (selective photothermolysis). The laser beam penetrates the skin until it encounters chromophore which absorbs the laser beam. After absorption of the laser beam, heat is generated to induce coagulation, necrosis of the targeted tissue, this results in removal of unwanted tissue by laser surgery. Laser resurfacing is a technique in which covalent bonds of a material are dissolved by a laser, a technique invented by aesthetic plastic surgeon Thomas L. Roberts, III using CO lasers in the 1990s.

text: a scientist of IBM who was using an excimer laser to make microscopic circuits in microchips for informatics equipment, discovered that the excimer could also be used to cut organic tissues with high accuracy without significant thermal damage. The discovery of an effective biological cutting laser, along with the development of computers to control it, enabled the development of new refractive surgery techniques. In 1983, Stephen Trokel, a scientist at Columbia University, in collaboration with Srinivasan, performed the first Photorefractive Keratectomy (PRK), or keratomileusis in situ (without separation of corneal layer) in Germany. The first patent for this approach, which

Xenon chloride (308 nm) excimer lasers can also treat a variety of dermatological conditions including psoriasis, vitiligo, atopic dermatitis, alopecia areata and leukoderma. As light sources, excimer lasers are generally large in size, which is a disadvantage in their medical applications, although their sizes are rapidly decreasing with ongoing development. Research is being conducted to compare differences in safety and effectiveness outcomes between conventional excimer laser refractive surgery and wavefront-guided or wavefront-optimized refractive surgery, as wavefront methods may better correct for higher-order aberrations. Excimer lasers are also widely used

Another innovation was the use of computer milled ceramic implants for repairing cavities. The use of a non-toxic chemical such as hydrogen peroxide or carbamide peroxide for tooth bleaching has become popular in the new century. In 2002, two Vancouver doctors, dermatologist Alastair Carruthers and ophthalmologist Jean Carruthers, pioneered the cosmetic use of the well known botulinum toxin. The pair noticed that subcutaneous injections of small amounts of the toxin had the effect of removing age wrinkles from the skin. The Botox procedure,

Moreover, published studies suggest that use of lasers for ENAP procedures and/or gingival curettage could render root surfaces and adjacent alveolar bone incompatible with normal cell attachment and healing." A 2015 systematic review from the AAP regeneration workshop acknowledged more recent peer-reviewed studies showing periodontal regeneration, and further suggested that the LANAP protocol's minimally invasive nature may offer advantages in the regeneration of defects where minimal soft tissue change is required.

The laser is intended to selectively remove diseased or infected pocket epithelium from the underlying connective tissue. The Nd:YAG laser has been shown to reduce levels of microbial pathogens in periodontal pockets and vaporize the pocket-lining epithelium without causing damage to the underlying connective tissue. The use of lasers in treating periodontal disease has been seen by some dental professionals as controversial. The American Academy of Periodontology stated in 1999 that it was "not aware of any randomized blinded controlled longitudinal clinical trials, cohort or longitudinal studies,

"Dermatology" By observing the numerous and complex interactions between light and biological materials, the field of biophotonics presents a unique set of diagnostic techniques that medical practitioners can utilize. Biophotonic imaging provides the field of dermatology with the only non-invasive technique available for diagnosing skin cancers. Traditional diagnostic procedures for skin cancers involve visual assessment and biopsy, but a new Laser Induced Fluorescence spectroscopy technique allow dermatologists to compare spectrographs of a patient's skin with spectrographs known to correspond with malignant tissue. This provides doctors with earlier diagnosis and treatment options. “Among optical techniques, an emerging imaging technology based

text: Lasers are also used for laser-assisted lipectomy. Various types of laser surgery are used to treat refractive error. LASIK, in which a knife is used to cut a flap in the cornea, and a laser is used to reshape the layers underneath, is used to treat refractive error. IntraLASIK is a variant in which the flap is also cut with a laser. In photorefractive keratectomy (PRK, LASEK), the cornea is reshaped without first cutting a flap. In laser thermal keratoplasty, a ring of concentric burns is made in the cornea, which cause its surface to steepen, allowing better near vision.

Ablative lasers are associated with higher rates of adverse effects compared with nonablative lasers, with examples being postinflammatory hyperpigmentation, persistent facial redness, and persistent pain. Physiologically, certain wavelengths of light, used with or without accompanying topical chemicals, are thought to kill bacteria and decrease the size and activity of the glands that produce sebum. As of 2012, evidence for various light therapies was insufficient to recommend them for routine use. Disadvantages of light therapy can include its cost, the need

There have been, however, anecdotal negative accounts of bad scarring and hyperpigmentation without any findings of infection. Erbium and CO fractional systems have a better safety profile than lasers of the past. Laser Types Intense Pulsed Light (IPL) uses flashlamps (and not lasers) to produce high intensity light over broad visible and infrared wavelengths with filters that select the desired range. IPL is used to treat dyschromia, rosacea, melasma, acne, photodamage, vascular and pigmented lesions, and rhytides. Beginning in the late 1990s, a number of studies have been

Nonablative lasers, such as the 585 nm pulsed dye laser, 1064 nm and 1320 nm , or the 1540 nm are used as laser therapy for hypertrophic scars and keloids. For burn scars they improve the appearance. Ablative lasers such as the carbon dioxide laser (CO) or offer the best results for atrophic and acne scars. Like dermabrasion, ablative lasers work by destroying the epidermis to a certain depth. Healing times for ablative therapy are much longer and the risk profile is greater compared to nonablative therapy; however, nonablative

PDT has the most supporting evidence of all light therapies. Many different types of nonablative lasers (i.e., lasers that do not vaporize the top layer of the skin but rather induce a physiologic response in the skin from the light) have been used to treat acne, including those that use infrared wavelengths of light. Ablative lasers (such as CO and fractional types) have also been used to treat active acne and its scars. When ablative lasers are used, the treatment

Unwanted side effects such as hypo- or hyper-pigmentation or, in extreme cases, burning of the skin call for an adjustment in laser selection or settings. Risks include the chance of burning the skin or discoloration of the skin, hypopigmentation (white spots), flare of acne, swelling around the hair follicle (considered a normal reaction), scab formation, purpura, and infection. These risks can be reduced by treatment with an appropriate laser type used at appropriate settings
