Effects of low-intensity laser therapy on the Orthodontic movement velocity of human teeth: a clinical study. <b>Brazilian Dental Journal</b>, v. 15, p. 84-84, 2004. Special issue.

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.84-84openAccessteethorthodontic treatmentssemiconductor laserslight emitting diodestherapybone tissuesResumos em periódicos15Special issue0000-0002-4203-11340000-0002-9379-9530https://orcid.org/0000-0002-4203-1134https://orcid.org/0000-0002-9379-9530Sem PercentilSem Percentil CiteScore
