Clinical and experimental knowledge of photobiomodulation in accelerated orthodontics: a review

Abstract

In recent years, there has been an increasing interest in finding a noninvasive method to induce the acceleration of dental movement, methods such as low intensity vibrations, pulsed electromagnetic fields, and low-level laser therapy (LLLT). There have been multiple studies on the efficacy of LLLT in animal models, in vitro and in patients without conclusive results. Objective: Evaluate the state of the art on the use of LLLT to increase the rate of the orthodontic tooth movement to create a concise reference guide of the different laser and protocols available. Materials and Methods: We searched online databases for articles with the keywords LLLT, LLLI, OTM, photobiomodulation. Results: We found conflicting information as to the efficacy of LLLT to accelerate OTM. There is no consensus in the way the irradiation should be performed. Conclusions: The lack of a standardized irradiation protocol makes it hard to compare conflicting results, even in cases where the laser have the same technical specifications.

Efectos de la fotobiomodulación en el tratamiento de ortodoncia. Revisión bibliográfica

“…En primer lugar, ( 16) está el láser de Neodimio, que emite una luz infrarroja de alta energía, utilizada para activar ciertos materiales de cementación (3,18). El cual es muy útil dentro de la ortodoncia, puesto que, permite un mayor control y precisión al colocar los Brackets en los dientes, mejorando la adhesión, la eficiencia del tratamiento de infecciones bucales y la desinfección de áreas afectadas (19).…”
