BACKGROUND: Oral pigmentation, especially in the gingiva poses esthetic problems. Laser therapy has been widely used for cosmetic therapy in dentistry. The aim of the present study was to systematically review the efficacy of surgical laser therapy (SLT) in the management of oral pigmented lesions (OPL). MATERIALS AND METHODS: The addressed focused question was "Is SLT effective in the management of OPL?" Databases (MEDLINE via PubMed; EMBASE; Cochrane Central Register of Controlled Trials and Cochrane Oral Health Group Trials Register databases) were searched from 1970 up to and including February 2017...

A new scheme for NH2 detection by means of laser-induced fluorescence (LIF) with excitation around wavelength 385nm, accessible using the second harmonic of a solid-state Alexandrite laser, is presented. Detection of NH2 was confirmed by identification of corresponding lines in fluorescence excitation spectra measured in premixed NH3-air flames and on NH2 radicals generated through NH3 photolysis in a nonreactive flow at ambient conditions. Moreover, spectral simulations allow for tentative NH2 line identification...

BACKGROUND: Becker's Nevus is an aesthetically troublesome condition secondary to hyperpigmentation and hypertrichosis. Although several lasers have been employed with varying degrees of success, the exact devices and treatment parameters have yet to be elucidated. OBJECTIVE: To assess the combination Nd:Yag and alexandrite laser as a safe and efficacious treatment for Becker's Nevus. METHODS: In a 20-year-old Fitzpatrick Skin Type IV male, a Becker's Nevus was treated with six sessions of long-pulsed 1,064nm Nd:Yag laser at six-week intervals followed by five sessions of long-pulsed 755nm alexandrite laser at three-month intervals...

The advent of targeted chemotherapy has led to the emergence of new dermatologic toxicities. We sought to use lasers and light devices to treat recalcitrant cutaneous adverse effects related to cancer treatment. Three stage III or IV cancer patients with cutaneous complications due to epidermal growth factor receptor (EGFR) inhibitors were treated with melanin and vascular-specific laser and light technologies. Two patients reported reduction in papulopustular eruption following pulse dye laser (PDL) treatment...

BACKGROUND AND OBJECTIVE: Laser-assisted treatment of tattoos is well recognized to produce opaque epidermal whitening that prevents multiple sequential passes during a single treatment session. The amount of epidermal whitening produced in association with the procedure can be minimized by topical application of perfluorodecalin (PFD), which is an optical clearing agent. This pivotal trial assessed the ability of a transparent PFD-infused patch used in conjunction with a Q-switched nanosecond laser in the treatment of tattoos to permit multiple laser passes during a single 5 minute treatment session in comparison to the number of passes that could be completed using conventional treatment of the tattoo with the laser alone...

BACKGROUND: Melasma is a common acquired facial hypermelanosis with irregular brownish macules and patches. The clinical course is often fluctuated and refractory to treatment. The present study was conducted to evaluate the efficacy and safety of pulsed alexandrite laser for the treatment of melasma. MATERIALS AND METHODS: In the present study, we enrolled Asian patients with melasma. All the patients received four monthly treatments with a pulsed alexandrite laser...

BACKGROUND: The diffractive optic coupled with a picosecond pulsed alexandrite laser has been shown to effectively minimize pigmen- tation while improving the appearance of textural irregularities and rhytides. We evaluated the safety and ef cacy of the diffractive optic laser treatment for off of the face applications including the hands and décolletage in a pico-toning technique. STUDY: 20 healthy female patients (40-70 years of age) were treated with a picosecond pulsed alexandrite laser with a diffractive lens...

BACKGROUND: A 755nm picosecond alexandrite laser with a diffractive lens array has been reported for the treatment of acne scar and photoaging with clinical ef cacy. In this study, we evaluated the application of the 755nm picosecond alexandrite laser with a diffractive lens array for facial photoaging in Chinese. MATERIALS AND METHODS: Ten subjects with moderate facial photoaging were enrolled in a prospective, evaluator-blinded, open-label, and split-face trial to assess the ef cacy and safety of the 755nm picosecond alexandrite laser with a diffractive lens array for facial photoaging...

INTRODUCTION: This study explored immediate heat signatures with different passing techniques and the delayed thermal data points with the picosecond Alexandrite laser with the 6mm at and fractional optic during and after treatment. We sought to clarify the im- mediate effects of heating and understand the thermal and short term clinical difference when using these optics. RESULTS: There were no immediate differences or a signi cant temperature rise with different passing techniques using the at or the fractional optic...

BACKGROUND: Excessive hair is undesirable and represents both a social and emotional burden, especially among females. Laser hair removal (LHR) has gained popularity in the past 2 decades. It is a common practice to instruct patients not to pluck or wax their hair before undergoing LHR; only shaving is allowed to improve the efficacy of the LHR. OBJECTIVE: To compare the percentage of hair reduction in preshaved versus prewax epilated axillae after LHR in healthy adult Saudi females...

BACKGROUND: Acanthosis nigricans (AN) is a brown to black, velvety hyperpigmentation of the skin that usually involves cutaneous folds. Treatment of AN is important regarding cosmetic reasons and various therapeutic modalities have been used for these purposes. The goal of this study was to compare the effectiveness of long-pulsed alexandrite laser and topical tretinoin-ammonium lactate for treatment of axillary-AN. METHODS: Fifteen patients with bilateral axillary-AN were studied in Razi Hospital, Tehran, Iran...

We present the first study of Q-switched Alexandrite lasers under continuous-wave diode-pumping with operation up to 10 kHz repetition rates in TEM<sub>00</sub>, with spatial quality M<sup>2</sup> 1.15. With a pulsed-diode dual-end-pumped design, pulse energy is scaled to a record level of 3 mJ. We also demonstrate, for the first time, cavity-dumped Q-switching of diode-pumped Alexandrite lasers under continuous-wave and pulsed diode-pumping, up to 10 kHz. Pulse energy of 510 μJ is demonstrated with 3 ns pulse duration and 170 kW peak power, in TEM<sub>00</sub> with M<sup>2</sup> < 1...

BACKGROUND: Laser therapy is the treatment of choice in tattoo removal. However, the precise mechanisms of laser-tattoo pigment interactions remain to be evaluated. METHODS: We evaluated the geometric patterns of laser-tattoo pigment particle interactions using a tattoo pigment-embedded tissue-mimicking (TM) phantom. RESULTS: A Q-switched (QS) neodymium-doped yttrium aluminum garnet laser was used at settings of 532-, 660-, and 1064-nm wavelengths, single-pulse and quick pulse-to-pulse treatment modes, and spot sizes of 4 and 7 mm...

INTRODUCTION: There is no satisfactory and efficient method for long-term removal of white-colored and thin hair. METHODS: We conducted a randomised clinical trial of hirsute patients with excessive white and/or thin hair on the face and/or axilla. In Group I (n: 16), the facial hair on one side of the face was painted with a black eyelash mascara immediately before Nd:YAG laser and the other half was only treated by Nd:YAG. In Group II (n: 20), the axillary hair on one side was painted with the mascara before the Alexandrite laser with the other side being only treated by Alexandrite...
