The Effect of Low-Level Laser Therapy on the Acceleration of Orthodontic Tooth Movement

Abstract

In clinical practice, low-level laser therapy (LLLT) is widely used. The main aim of this review is to assess the effectiveness of LLLT in accelerating tooth movement in human subjects. The PRISMA checklist was utilized as a guideline to carry out this systematic review. The electronic databases were searched from Google Scholar (2014-2018) and PubMed, and comprehensive research on this topic was also manually conducted. Therefore, 77 articles randomized clinical trials (RCTs) or controlled clinical trials (CCTs) were selected. After screening studies, consequently, eleven trials met the inclusion criteria. Eight out of 11 studies showed LLLT has a significant impact on the acceleration of orthodontic tooth movement, and there was no statistically significant difference in the rate of tooth movement between the laser group and the control group in the two remaining studies. Furthermore, five out of 11 articles showed that LLLT has no adverse effects. Although we have some degree of understanding from a cellular point of view to LLLT effects, we still do not know whether these cellular level changes have any effect on the clinical acceleration of orthodontic tooth movement. The results are inconclusive and cannot be generalized to the public community; therefore, well-structured studies are required.

Speeding Orthodontics: A Review Article

“…There is a weak evidence support the application of pulsed electromagnetic field electromagnetic to accelerate OTM (8,9) . Low-level laser therapy (LLLT) has been used to hasten OTM in recent years (10,11) . Colson et al, 2017 stated that LLLT can be effective for speeding OTM (10) .…”

Die orthodontische Zahnbewegung

“…einer Wellenlänge von 300 bis 10 600 nm, einer Pulsfrequenz von 0 bis 5000 Hz, einer Intensität von 10 -2 bis 10 2 J/cm 2 und einem elektromagnetischen Spektrum von 630 bis 980 nm (sichtbares bis fast sichtbares Rot) durchgeführt. In der Kieferorthopädie wird diese Lasertherapie auch gegen kleine Schmerzempfindungen angewendet [17]. Eine niedrige bis sehr niedrige Evidenz zeigt, dass die Low-Level-Laser Therapie die Zahnbewegungsgeschwindigkeit erhöhen kann.…”

Orthodontic Bracket Removal Using LASER-Technology—A Short Systematic Literature Review of the Past 30 Years

“…Laser techniques are now also available for use during orthodontic treatment and studies have proved their use to be advantageous [7][8][9][10]. Soft tissue lasers are often used for procedures such as gingivectomy and frenectomy of surgical exposure of impacted teeth because they inhibit bleeding and swelling, offer an improved cut precision, reduce the pain for the patient and prevent to some degree wound contraction [5,6,[11][12][13].…”
