Resumen
Low-intensity laser therapy (LILT) has been studied in many
fields of Dentistry, but, to our knowledge, it is the first time that
its effects on orthodontic movement velocity in humans are
investigated. In our study, eleven patients were recruited for a
two-month study. One half of the upper arcade was considered
control group and received mechanical activation of the canine
teeth every thirty days. The opposite half received the same
mechanical activation and was also irradiated with a diode laser
(?=780nm) on ten points around the root, during 10s with 20
mW, 5 J/cm2, on four days of each month. Data of the biometrical
progress of both groups were statistically compared. All
patients showed significant higher retraction velocity of the
canines on the laser treated side when compared to the control.
Conclusion: Our findings suggest that LILT does accelerate human teeth movement and could therefore considerably shorten
the whole treatment duration.
