OBJECTIVE: This study explored the outcome of applying red/near-infrared light therapy using light-emitting diodes (LEDs) pulsed with three different frequencies transcranially to treat traumatic brain injury (TBI) in Veterans. BACKGROUND: Photobiomodulation therapy (PBMT) using LEDs has been shown to have positive effects on TBI in humans and animal models. MATERIALS AND METHODS: Twelve symptomatic military Veterans diagnosed with chronic TBI >18 months post-trauma received pulsed transcranial PBMT (tPBMT) using two neoprene therapy pads containing 220 infrared and 180 red LEDs, generating a power output of 3...

OBJECTIVE: Perform systematic literature review on photobiomodulation (PBM) devices used at home for nonesthetic applications. BACKGROUND: Home-use PBM devices have been marketed for cosmetic and therapeutic purposes. This is the first systematic literature review for nonesthetic applications. METHODS: A systematic literature search was conducted for PBM devices self-applied at home at least thrice a week. Two independent reviewers screened the articles and extracted the data...

OBJECTIVE: The aim of this in vitro study was to evaluate the effectiveness of antimicrobial photodynamic therapy (aPDT) composed of the association of the photosensitizer (PS) erythrosine irradiated by a high-intensity dental light source against a culture of Streptococcus mutans, comparing this effect with that of a 0.12% chlorhexidine solution. MATERIALS AND METHODS: For this purpose, planktonic suspensions of S. mutans were subjected to experimental conditions in which three different concentrations of erythrosine (E) (2, 4, and 8 μM) associated with three different doses emitted by the light source (L) (48, 96, and 144 J/cm2 ) were crossed, corresponding to the exposure times of 40, 80, and 120 sec, respectively, delivered in pulsed mode...

OBJECTIVE: Our objective was to test the antidepressant effect of transcranial photobiomodulation (t-PBM) with near-infrared (NIR) light in subjects suffering from major depressive disorder (MDD). BACKGROUND: t-PBM with NIR light is a new treatment for MDD. NIR light is absorbed by mitochondria; it boosts cerebral metabolism, promotes neuroplasticity, and modulates endogenous opioids, while decreasing inflammation and oxidative stress. MATERIALS AND METHODS: We conducted a double-blind, sham-controlled study on the safety and efficacy (change in Hamilton Depression Rating Scale [HAM-D17 ] total score at end-point) of adjunct t-PBM NIR [823 nm; continuous wave (CW); 28...

OBJECTIVE: The purpose of this prospective analysis was to evaluate the efficacy of erbium-substituted yttrium aluminum garnet (Er:YAG) laser compared with that of conventional surgery, regarding the long-term outcome of nondysplastic oral leukoplakias (OL). BACKGROUND: To date, this comparison has never been performed. METHODS: Patients were randomly allocated to two different groups: some underwent surgical excision with traditional scalpel (Group TrSc) and others underwent an ablative session with Er:YAG laser (Group Las), with these modalities: 1...

OBJECTIVE: The objective of the present study was to investigate the application of a carbon arc lamp on wound healing in a rat cutaneous full-thickness wound model. BACKGROUND DATA: In clinical practice, wound healing has been promoted by irradiation with a carbon arc lamp. However, the corresponding mechanism has not been clearly defined. METHODS: A cutaneous full-thickness wound on the back of rats was irradiated using a carbon arc lamp at a wavelength peak range of 620-740 nm with 54 J/cm2 ...

OBJECTIVE: To describe a clinical case of successful conservative management of Localized Juvenile Spongiotic Gingivitis Hyperplasia (LJSGH) using photodynamic therapy (PDT) and reviews the current literature on this pathology. BACKGROUND DATA: LJSGH is a recently described rare disease with controversial treatment results. As of today, 13 publications report surgical treatment approaches. The use of CO2 laser and cryotherapy was reported only in one study. The use of PDT was not previously reported...

OBJECTIVE AND BACKGROUND: To report on a case of cyclosporine A-related gingival overgrowth (GO) treated by conventional scaling and Erbium:YAG laser that unexpectedly showed complete healing with normalization of the gingiva, making unnecessary further surgical treatment for gingival volume reduction. Since Erbium:YAG laser was approved in 1997 by the U.S. Food and Drug Administration for hard and soft tissue treatments in dentistry, several studies have been published to demonstrate its efficacy for bone cutting, plaque and subgingival calculus removal, and antiseptic effects both on soft and hard periodontal tissues...

OBJECTIVE: To determine the optimal parameters of power, energy, and time for the application of a carbon dioxide laser for Tribal Black ink tattoo removal. BACKGROUND DATA: The use of antiquated techniques to remove tattoos demonstrates the difficulty of making advances in this field. Studies by the American Society for Dermatologic Surgery have shown that 5% of the global population has at least one tattoo on the body, with 10% of them wanting a tattoo to be removed...

OBJECTIVE: To determine surface roughness caused by Er:YAG laser irradiation and its effect on the increase in bacterial adhesion. BACKGROUND: Er:YAG laser was proposed as a strategic device to reduce caries by its ability to generate chemical and structural changes in tooth enamel; in turn, it produces undesirable effects on the tooth surface that could increase its roughness and allow a greater accumulation of microorganisms. METHODS: Eighty-four samples of human enamel were divided into seven groups (n = 12): G1_control (no laser irradiation); G2_100/H2 O, G3_200/H2 O, and G4_300/H2 O were irradiated with Er:YAG laser (12...

OBJECTIVE: To compare the shear bond strength (SBS) values of orthodontic brackets luted using a resin-modified glass ionomer cement (RMGIC) on enamel surfaces etched using either an Er:YAG laser in two different working modes, or a conventional etching protocol, including phosphoric acid. MATERIALS AND METHODS: Sixty healthy human premolars were randomly allocated to three experimental groups (n = 20) and etched with: Group 1: Er:YAG laser in super-short pulse (SSP) mode (100 mJ, 20 Hz, 2 W); Group 2: Er:YAG laser in quantum square pulse mode (120 mJ, 10 Hz, 1...

OBJECTIVE: To evaluate the effect of erbium: yttrium aluminium garnet laser conditioning bond strength of orthodontic brackets on porcelain surfaces. BACKGROUND: There are few studies that evaluate the effect of Er:YAG laser about orthodontic bonding on porcelain surface. The efficacy of Er:YAG laser in porcelain conditioning is controversial. MATERIALS AND METHODS: Ninety ceramic specimens were randomly divided into five group, group A: etched with hydrofluoric (HF) acid; group B and C: etched with an energy parameter of 250 mJ, 20 Hz and 300 mJ, 20 Hz by Er:YAG laser instrument; group D and E: etched with an energy parameter of 250 mJ, 20 Hz and 300 mJ, 20 Hz of Er:YAG laser with HF etching...

OBJECTIVE: To evaluate whether Er:YAG laser etching could be an alternative surface treatment to hydrofluoric (HF) acid etching. BACKGROUND: Surface treatment is important to bonding properties and utility times of computer aided design/computer aided manufacture (CAD/CAM) dental ceramics.

OBJECTIVE: To evaluate the effects of bracket removal using an erbium laser on the pulp temperature and enamel surface. BACKGROUND: Removal of orthodontic brackets with conventional debonding pliers may result in enamel cracks. To avoid damage to the enamel surface and effectively remove metal or ceramic brackets, different types of lasers, such as Nd:YAG, CO2 , TM:YAP, diode laser, or Er:YAG, have been introduced for debonding. MATERIALS AND METHODS: A total of 55 brackets (n = 55; 20 metal and 35 ceramic ones) were bonded to 55 caries-free premolars extracted for orthodontic indications...

OBJECTIVE: In this in vitro study, cross-polarization optical coherence tomography (CP-OCT) was used to evaluate microleakage in dental composite restorations bonded to enamel with two types of one-step self-etching (SE) adhesives. BACKGROUND DATA: One-step SE adhesives were proposed to simplify bonding of composite restorations. However, bonding of these simplified adhesive to dental enamel is still questionable. OCT is a promising diagnostic tool that allows micron-scale imaging of biological tissues and structures...

BACKGROUND: To obtain the best result from flexor tendon repair surgery, proper surgical technique, appropriate materials, good rehabilitation, and patient satisfaction are essential to consider. Nevertheless, no general unique protocol still exists between researchers, for a suitable treatment plan.
