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.

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
Magnetic resonance imaging-guided laser interstitial thermal therapy (LITT) is an ablative procedure using heat from a laser to provide cytoreduction in tissue. It is a minimally invasive procedure that has been used in intracranial pathologies such as high-grade gliomas, metastatic lesions, epilepsy, and other lesions. While LITT may offer a more acceptable complication profile compared to open surgery, the role of laser therapy for intracranial lesions in current treatment paradigms continues to evolve. This review will focus on the background and application of LITT, the current evidence for its use, and future directions for the technology.

This chapter explains the steps necessary to perform laser surgery upon single adherent mammalian cells, where individual organelles are extracted from the cells by optical tweezers and the cells are monitored post-surgery to check their viability. Single-cell laser nanosurgery is used in an increasing range of methodologies because it offers great flexibility. Its main advantages are (a) there is not any physical contact with the cells so they remain in a sterile environment, (b) high spatial selectivity so that single organelles can be extracted from specific areas of individual cells, (c) the method can be conducted in the cell's native media, and (d) in comparison to other techniques that target single cells, such as micromanipulators, laser nanosurgery has a comparatively high throughput.

"Theatre acting is the operation with ascalpel, movie acting is an operation with a laser". Michael Caine. Being the instrument in hands of urologist laser is much more than a single-application device. Its applicability is deeply dependent on physical properties, settings, and environment. With knowledge of how the device work, why it affects the tissue, and how this laser-tissue interaction goes surgeon can shape further clinical work to choose the best devices or techniques of surgery. Tailoring the laser effects on the needs of the patient. In this paper, we tried to briefly describe what a laser device consists of, the most important laser-tissue interactions that are necessary for understanding the operation of the laser, and the main laser systems that are used in urology.

Review
BACKGROUND
Resection of lung metastases with curative intention in selected patients is associated with prolonged survival. Laser-assisted resection of lung metastases results in complete resection of a high number of lung metastases, while preserving lung parenchyma. However, data concerning laser lung resections are scarce and contradictory. The aim of this study was to conduct a systematic review to evaluate the utility of laser-assisted pulmonary metastasectomy.
METHODS
An electronic search in MEDLINE (via PubMed), complemented by manual searches in article references, was conducted to identify eligible studies.
RESULTS
Fourteen studies with a total of 1196 patients were included in this metanalysis. Laser-assisted surgery (LAS) for lung metastases is a safe procedure with a postoperative morbidity up to 24.2% and almost zero mortality. LAS resulted in the resection of a high number of lung metastases with reduction of the lung parenchyma loss in comparison with conventional resection methods. Survival was similar between LAS and conventional resections.
CONCLUSION
LAS allows radical lung-parenchyma saving resection of a high number of lung metastases with similar survival to conventional methods.
