“…10 However, more tissue damage occurs than with the use of a scalpel, 19 but this damage is not prejudicial to the specimen tissue, specially when the specimens contained a diameter of at least 5 mm. 11 In the current study, the tissue damage was minimal, and only one lesion was measured at 5 mm in diameter. In addition, the LASER characteristics and settings, such as power output, wavelength, emission modalities, type of optical fiber, and affinity with target tissues can control the width and severity of the thermal damage caused to the tissue.…”

“…In addition, the LASER characteristics and settings, such as power output, wavelength, emission modalities, type of optical fiber, and affinity with target tissues can control the width and severity of the thermal damage caused to the tissue. 11 By contrast, diode LASER surgery provides a thermal damage zone of less than 1mm, which allows for surgical precision and excellent hemostasis within a dry operative field. 20,21 Hemostasis caused by LASER surgery is due to the increase in platelet activation at the end point of the wound, which leads to the sealing of the blood vessels.…”

“…Surgical LASER have been used to treat oral lesions, including: 1) Potassium Titanyl Phosphate (KTP), 2) neodymium-yttrium-aluminium-gamet (Nd:YAG), 3) carbon dioxide (CO2), and 4) diode LASER with semiconductors. 10,11 High-power diode LASER, as compared to other high-power LA-SER, are more portable, compact, and cost effective. Diode LASER have wavelengths of between 805 and 980nm that can be used in continuous or pulsed mode, according to the clinical recommendation,using an optical fiber with or without contact.…”

a b s t r a c t a r t i c l e i n f o Article history:Received 17 April 2016Accepted 13 January 2017 Available online 30 March 2017Objective: Fibrous hyperplasia is frequently treated by surgical incision with a scalpel associated with removal of chronic trauma. However, hemostasis of the surgical wound is specially difficult for patients with hemorrhagic disorders or those undergoing antithrombotic therapy without the suturing of the wound borders. High-power LASER have been applied as a useful tool in the management of soft tissue lesions. Therefore, the present study aimed to present a prospective case series of fibrous hyperplasia treated using a high-power diode LASER.Methods: Fifteen patients with fibrous hyperplasia were enrolled in this study. LASER irradiation was performed using an 808 nm diode LASER with an optical fiber of 600 µm, at a power of 2.0W to 3.5W (average 2.96W), in a continuous-wave mode. The treatment performance of fibrous hyperplasia using a high-power diode LASER was determined by evaluating the pain, postoperative functional alterations, edema, secondary infection and bleeding.Results: Diode LASER surgery proved to be effective and presented a good performance in the treatment of fibrous hyperplasia. Conclusions Cirurgia oralObjetivo: Hiperplasia fibrosa é frequentemente tratada pela excisão cirúrgica com bisturi associado com a remoção do trauma crônico. Entretanto, hemostasia da ferida cirúrgica é especialmente dificultada em pacientes com desordens hemorrágicas ou aqueles submetidos a terapia anticoagulante sem sutura das bordas das feridas cirúrgicas. LASER de alta intensidade tem sido utilizados como uma ferramenta útil no manejo de lesões de tecidos moles. Portanto, o presente estudo objetiva-se a apresentar uma série de casos prospectivo no tratamento da hiperplasia fibrosa utilizando o LASER de diodo de alta intensidade.Métodos: Quinze pacientes com hiperplasia fibrosa foram envolvidos no estudo. A aplicação do LASER foi realizada utilizando um LASER de diodo de 808nm com uma fibra óptica de 600μm, em uma potência de 2.0W a 3.5W (média 2.96W), em modo continuo. A eficácia do tratamento da hiperplasia fibrosa utilizando LASER de diodo de alta intensidade foi determinada pela avaliação da dor, alterações funcionais pós-operatórias, edema, infecção secundária e sangramento.Resultados: O LASER cirúrgico de diodo provou ser efetivo e apresentou bom resultado no tratamento da hiperplasia fibrosa.Conclusões: Ensaios clínicos randomizados devem ser realizados comparando LASER de diodo e outros sistemas de LASER com a cirurgia convencional e eletrocautério no manejo da hiperplasia fibrosa e outras lesões orais.

Introduction: Recently, a wide variety of procedures have been done by laser application in orthodontics. Apart from the mentioned range of various treatments, laser has become a tool for many soft tissue surgeries as an alternative to conventional scalpel-based technique during orthodontic treatments in the management of soft tissue. Due to scarce information in the latter subject, this study was designed in order to include clinical trials that included soft tissue ablation by laser in orthodontics. Methods: Literature was searched based on PubMed and Google Scholar databases in 5 years (2010)(2011)(2012)(2013)(2014)(2015) with English language restriction and clinical trial design. Studies that performed soft tissue application of laser during orthodontic treatment were extracted by the authors. Results: Only eight studies met the inclusion criteria. No significant difference was found between laser ablation and conventional scalpel technique in the matter of treatment outcome. However, few issues remained to clarify the differences in the mentioned procedures. Conclusion: Laser performance can be recommended in case of preceding less bleeding and discomfort during surgical procedure. There are still quandaries among clinical application of scalpel-based surgery in aesthetic region with bracket-bonded teeth. Precaution and knowledge regarding the characteristics of laser beam such as wavelength, frequency, power and timing is extremely needed.

“…Os autores concluíram que não há interferência no resultado do exame histológico, independentemente da técnica utilizada, desde que a lesão seja maior que 7 mm. Já para Angiero et al 17 , que também estudaram os danos causados pelo uso do laser na remoção de lesões em tecido mole e a sua interferência na análise histológica, a lesão deve ter no mínimo 5 mm para que os danos não interfiram nesse tipo de diagnóstico.…”
