A utilização do laser em Ortodontia

Abstract

melhor pós-operatório, entre muitas outras vantagens. A Ortodontia também tem muito a ganhar com a utilização da luz laser, apesar de suas aplicações e seus efeitos não se encontrarem bem difundidos entre os profissionais. O presente trabalho objetivou realizar uma revisão na literatura a fim de elucidar o ortodontista sobre como ele poderá se beneficiar desta forma de energia, elevando a qualidade do seu trabalho e melhorando as condições do tratamento tanto para o profissional como para o paciente.Palavras-chave: Lasers. Ortodontia. Odontologia.

Analgesia durante o tratamento ortodôntico com o uso do laser de baixa intensidade: revisão sistemática

“…Used between 800 and 830 nm, AsGaAl laser has shown the best analgesic effects. This active medium is a semiconductor diode with favorable features for a photochemical action of tissue analgesia, in addition to anti-inflammatory action and tissue biostimulation 14,15 . One study has used gaseous carbon dioxide (CO 2 ) laser, although without specifying wavelength.…”

“…A control group without any type of intervention is a good strategy to perceive real pain experienced by patients, since the possibility of a placebo effect is nonexistent or decreased. Dosimetry, which is the ratio between energy transmitted by a laser emitter and the light beam irradiation surface 15 , has shown significant differences among studies. This broad variation of application protocols is possibly due to the attempt to study different ways of using laser during orthodontic treatment.…”

“…Exposure time of current equipment is directly calculated. The dentist programs the device with the desired energy density and wait for the indication of the application time 15 . Our study has observed that included clinical trials have followed a laser punctual application methodology, using the visual analog scale to measure pain.…”

Effectiveness of CO2 laser in removal of papillary gingival hyperplasia

“…Another kind of treatment for gingival hyperplasia is the use of laser. 8 "Laser" is a shortening for Light Amplification by Stimulated Emission of Radiation. 15 Its use in Dentistry, by means of many therapeutical properties, has called the attention of professionals and researchers, since development of Rubi laser in 1960, by Theodore Maiman.…”

Efeitos do laser de baixa intensidade na sensibilidade dolorosa durante a movimentação ortodôntica

“…In clinical practice, there is almost a consensus that therapy with low level laser (LLL) or laser therapy (LT) causes analgesic effect. 3,10,13,15,19,24 Thus, laser could become an important aid for orthodontic treatment 6,9,13,14,20 since fear of feeling pain is one of the main factors which discourages many patients to undergo this kind of treatment. 1,4,25 Low level laser reduces pain through two different mechanisms: Stimulating the production of beta-endorfine, a natural mediator produced by the organism to reduce pain, and inhibiting the release of arachidonic acid, from the damaged cells, which would generate metabolites that interact with the pain receptors.…”
