ABSTRACT
ABSTRACT 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.

La cirugía con láser de dióxido de carbono (CO2) tiene la ventaja de evaporar los tejidos blandos con un mínimo de sangrado, dolor y retracción de la cicatriz quirúrgica. En este estudio que se realizó en el Departamento de Cirugía Oral y Maxilofacial de la Facultad de Odontología de la Universidad Autónoma de Tamaulipas, se evaluaron 30 pacientes distribuidos en dos grupos a los cuales se les realizaron diversos procedimientos quirúrgicos empleando el equipo de láser CO2 y los métodos convencionales, para demostrar las ventajas y sus principales aplicaciones

Foi estudada uma faixa de tecido gengival removida na gengivectomia, quando a incisão é realizada de 1 a 2 mm apical ao ponto determinado pelo uso da sonda demarcadora, tendo em vista que a profundidade da sondagem é influenciada por diferentes fatores, entre os quais, o estado do tecido, 28 biópsias obtidas de 21 pacientes de 13 a 46 anos de idade foram analisadas morfologicamente com a aplicação de um Indice Histológico Gengival (I.H.G.). Os resultados revelaram: em 68,86 por cento dos casos um I.H.G. = 0, em 32,14 por cento um I.H.G. = 1 relacionado com o ponto de demarcação e o fundo do sulco, e nenhuma evidência de I.H.G. mais elevados. Esses resultados indicam que a incisão realizada de 1 a 2 mm apical aos pontos sagrantes, leva à remoção de uma faixa de tecido gengival normal
