INTRODUCTION
In dental practice, low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthodontic movement, accelerate bone regeneration after rapid maxillary expansion, and enhance orthodontic tooth movement, HILT, in turn, has been seen as an alternative for addressing soft tissue complications associated to orthodontic treatment.
OBJECTIVE
The aim of this study is to discuss HILT applications in orthodontic treatment.
METHODS
This study describes the use of HILT in surgical treatments such as gingivectomy, ulotomy, ulectomy, fiberotomy, labial and lingual frenectomies, as well as hard tissue and other dental restorative materials applications.
CONCLUSION
Despite the many applications for lasers in Orthodontics, they are still underused by Brazilian practitioners. However, it is quite likely that this demand will increase over the next years - following the trend in the USA, where laser therapies are more widely used.

PURPOSE OF REVIEW
The goal of this review is to summarize the field to date and to discuss strengths and limitations of low-level laser (light) therapy (LLLT) for the future investigation as a treatment of inflammatory disease.
RECENT FINDINGS
LLLT is a promising therapeutic, particularly for those diseases of skin and joints because they are most accessible to treatment. Indeed, the known mechanisms of LLLT support its use for anti-inflammatory purposes, as well as stimulation of tissue growth and repair. Although the standard of care for the majority of inflammatory diseases is immunosuppressive agents such as corticosteroids with undesirable toxicities, LLLT offers a unique approach by being non-invasive and incurring minimal side effects. It is also relatively inexpensive and accessible and even has the possibility to be patient directed at home. There is evidence that LLLT is able to modulate the immune system at the skin and joint, and it has been shown to be efficacious in humans by affecting bacterial colonization as it may pertain to chronic rhinosinusitis. However, there is variability in the methods of laser application as well as a lack of evidence for laser type, dose-ranging studies, and wavelength selection that create barriers to the implementation of LLLT without further more rigorous and standardized study. The heterogeneity makes it difficult to draw strong conclusions about the efficacy of LLLT and its mechanisms.

Dental and Medical Problems 2023Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically.
OBJECTIVES
The present study aimed to review clinical trials on the treatment of DH with laser therapy through a systematic review and meta-analysis.
MATERIAL AND METHODS
The search of electronic databases resulted in 562 publications up to April 2020. The inclusion criteria were studies carried out on humans and reporting on the treatment of DH with laser therapy. Case reports, literature reviews and systematic reviews were excluded. Selected by abstract, potentially eligible papers were read in full (n = 160). Independent examiners performed data extraction and the assessment of the risk of bias.
RESULTS
A total of 34 studies were included in the analysis, and 11 in the quantitative analysis. It was observed that most studies followed up patients for a maximum of 6 months (55%). Through the meta-analysis, we observed statistically significant differences between the average pain before and after 3 months of treatment with highand low-power lasers. However, through indirect comparisons, it was observed that the high-power laser showed a greater tendency to reduce the pain levels after 3 months of treatment as compared to the low-power laser, but without a statistically significant difference.
CONCLUSIONS
It was possible to conclude that regardless of the type of laser used in the treatment of DH, this treatment is an effective option for the control of pain symptoms. However, it was not possible to establish a defined treatment protocol, since the evaluation methods are very different from each other. Text for Rewiew and clinical cases.

The purpose of this study was to assess skin elasticity, the reduction in the number and the depth of wrinkles and changes in the other skin defects (bags under the eyes, dark circles under the eyes, skin hyperpigmentation in the ageing eye area following the use of non-ablative fractional laser, bipolar radiofrequency and intense pulsed light). Moreover, the study was also comparison which device brought better results than the others. This study included 71 patients (66 women, 5 men), aged 33-63 years (the average age was 45.81 years) with skin phototypes II and III. Twenty-four patients received five treatment sessions with a 1410-nm non-ablative fractional laser in 2-week intervals, 23 patients received five treatment sessions with a bipolar radiofrequency in 1-week intervals and 24 patients received five treatment sessions with an intense pulsed light in 2-week intervals. The treatment was applied on the skin in the eye area. The Cutometer (Courage + Khazaka electronic) reference test was used as an objective method for the assessment of skin elasticity. A questionnaire was used to compare baseline state with changes that occurred after the series of treatment sessions. The results of cutometric measurements of R2, R6 and R7 parameters and the results of questionnaires indicated that non-ablative fractional laser therapy, bipolar radiofrequency and intense pulsed light improved skin elasticity. Of the three treatments, the most significant percentage improvement in the R6 parameter was demonstrated by non-ablative fractional laser therapy which gave better final results than the other methods (p < 0.0001). No other statistically significant relationships were found between RF and IPL. In the (subjective) opinion of study participants (questionnaire), all used methods resulted in the reduction of the amount and the depth of wrinkles. However, they did not observe significant impact of individual treatment method on the signs of skin ageing, including discolorations within eye area, bags (fatty hernia), dark circles (vascular/pigmentary) and oedema (predisposition to water retention). Non-ablative fractional laser therapy, bipolar radiofrequency and intense pulsed light improved skin elasticity and the reduction of wrinkles. The most significant improvement of elasticity was demonstrated by laser therapy. It seems necessary to expand the group with the effect of individual treatments against bags and dark circles under the eyes.

Review
INTRODUCTION
Lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is one of the most common diseases affecting the aging man, with almost 80% of men greater than 70 affected. Historically, transurethral resection of the prostate (TURP) has been considered the historical gold standard in the treatment of LUTS due to BPH for many years, contemporary literature indicates that holmium laser enucleation of the prostate (HoLEP) has replaced TURP and open simple prostatectomy as the size independent surgical gold standard for BPH treatment.
MATERIALS AND METHODS
In this review, we discuss the current techniques utilized, outcomes and safety, as well as the long term durability of results. Adverse events associated with the HoLEP procedure, both enucleation and morcellation, are covered as well.
RESULTS
HoLEP has a robust body of literature supporting the technique, which demonstrates its ability to surpass other surgical BPH procedures, including TURP and open simple prostatectomy. Additionally, there is long term durability of both subjective and objective outcomes greater than 10 years associated with this procedure. One randomized trial showed specific postoperative outcome measures that were superior to TURP at 7 years of follow up, including Qmax (4.36 mL/s improvement), erectile function (2.39 points improvement on the IIEF erectile function section), and weight of prostate removed (15.7 grams greater), while other studies have shown greater reduction in postoperative PSA, lower detrusor pressure at Qmax, and more.
CONCLUSIONS
Overall, HoLEP has proven to be an extremely durable and effective treatment for patients suffering from LUTS due to BPH. Both the Europeans and AUA guidelines on the surgical treatment of BPH recommend HoLEP as a size-independent treatment option for those men with moderate to severe symptoms. HoLEP is an excellent option for many patients who may not be good candidates for other procedures based on prostate size, age, or bleeding risk.

Comparative Study Review
PURPOSE
To compare the operating modes of the Holmium:YAG laser and Thulium fiber laser. Additionally, currently available literature on Thulium fiber laser lithotripsy is reviewed.
MATERIALS AND METHODS
Medline, Scopus, Embase, and Web of Science databases were searched for articles relating to the operating modes of Holmium:YAG and Thulium fiber lasers, including systematic review of articles on Thulium fiber laser lithotripsy.
RESULTS
The laser beam emerging from the Holmium:YAG laser involves fundamental architectural design constraints compared to the Thulium fiber laser. These differences translate into multiple potential advantages in favor of the Thulium fiber laser: four-fold higher absorption coefficient in water, smaller operating laser fibers (50-150 µm core diameter), lower energy per pulse (as low as 0.025 J), and higher maximal pulse repetition rate (up to 2000 Hz). Multiple comparative in vitro studies suggest a 1.5-4 times faster stone ablation rate in favor of the Thulium fiber laser.
CONCLUSIONS
The Thulium fiber laser overcomes the main limitations reported with the Holmium:YAG laser relating to lithotripsy, based on preliminary in vitro studies. This innovative laser technology seems particularly advantageous for ureteroscopy and may become an important milestone for kidney stone treatment.

Review
OBJECTIVES
A wide and evolving range of lasers and their applications often makes it difficult for a busy surgeon to choose the ideal laser for a specific indication. With this in mind, this article aims to summarize the most recent literature concerning laser application in rhinology.
METHODS
A literature search from 2000 to 2020 using the PubMed database was employed. Keywords used included "laser," "rhinology," "endonasal endoscopic surgery," "hereditary haemorrhagic telangiectasia," "rhinitis," "refractory rhinitis," "Inferior turbinate hypertrophy," "dacryocystorhinostomy," "septoplasty," "cartilage reshaping" and "choanal atresia." The most up to date studies published for each rhinology condition that could potentially be treated with laser surgery was included.
RESULTS
Rhinological conditions appropriate for laser applications are discussed. We identified articles related to a number of applications including hereditary hemorrhagic telangiectasia, rhinitis, turbinate surgery, dacryocystorhinostomy, septoplasty, choanal atresia, and sphenopalatine artery ligation, paying attention to the outcomes of the studies and their limitations.
CONCLUSIONS
There is currently no one-size-fits-all laser and therefore being up to date on the latest clinical application results can help the clinician decide which are the best treatments to offer their patients.

Review
Since 2010 the FDA has approved laser systems as capable of producing a "temporary increase in clear nails" in patients with onychomycosis. Fungal eradication is probably mediated by heat in infrared laser systems; their efficacy has been confirmed thermographically, histologically and in electron microscopy. Another approach to decontaminate the nail organ is to disrupt fungi and spores by q-switched pulse applications. Recently specific combinations of wavelengths have been tested for their ability to disrupt the mitochondrial transmembrane potential at physiological temperatures by generating ATP and ROS. While clinically extremely high clearance rates of approximately 87.5-95.8 % have been reported, in-vitro investigations have failed to confirm the clearance. The variety of systems and advised parameters hampers a systematic evaluation. Recommendations for safe and practical treatment protocols, informed consent items, and combination with conventional treatment options are all areas of active work. Currently there is a lack of data concerning the long-term efficacy of laser therapy of onychomycosis; certified treatment protocols are needed.

Review
Over the past two decades, selective laser trabeculoplasty (SLT) has increasingly become an established laser treatment used to lower intraocular pressure in open-angle glaucoma and ocular hypertensive patients. In this review we trace the origins of SLT from previous argon laser trabeculoplasty and review the current role it has in clinical practice. We outline future directions of SLT research and introduce emerging technologies that are further developing this intervention in the treatment paradigm of glaucoma.
