Low-level laser therapy and laser acupuncture therapy for pain relief after initial archwire placement : A randomized clinical trial.
Study Goal
The researchers aimed to compare the effectiveness of low-level laser therapy (LLLT) and laser acupuncture therapy (LAT) in reducing pain after initial orthodontic archwire placement.
Results Summary
The study found no significant difference in pain reduction between LLLT, LAT, ibuprofen, and placebo laser treatment. Pain intensity peaked within the first two days post-archwire placement and diminished by the seventh day.
Population
60 female patients requiring premolar extractions for orthodontic crowding.
Effective Dosage
LLLT (808 nm, 200 mW, 2 J/cm²)
Duration
Pain was monitored up to seven days post-intervention.
Interactions
None mentioned
| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
low-level laser therapy (LLLT) | decrease | pain | orthodontic patients | - | were as effective as ibuprofen and placebo laser treatment for pain reduction | #1 |
laser acupuncture therapy (LAT) | decrease | pain | orthodontic patients | - | were as effective as ibuprofen and placebo laser treatment for pain reduction | #2 |
ibuprofen (400 mg) | decrease | pain | orthodontic patients | - | were as effective as low-level laser therapy and laser acupuncture therapy for pain reduction | #3 |
placebo laser treatment | decrease | pain | orthodontic patients | - | were as effective as low-level laser therapy and laser acupuncture therapy for pain reduction | #4 |
initial archwire placement | increase | intensity of spontaneous and biting pain | female patients who required four premolar extractions to relieve crowding | - | increased up to the first or second days | #5 |
initial archwire placement | decrease | intensity of spontaneous and biting pain | female patients who required four premolar extractions to relieve crowding | negligible value | diminished to a negligible value by the seventh day | #6 |

OBJECTIVE: Pain is among the most unpleasant experience during fixed orthodontic therapy. This study compared the effectiveness of low-level laser therapy (LLLT) and laser acupuncture therapy (LAT) in pain reduction after initial archwire placement. METHODS: This randomized, parallel-group, single-blind clinical trial included 60 female patients who required four premolar extractions to relieve crowding. The subjects were randomly designated into four groups of 15. After placement of the initial orthodontic archwire, patients in group 1 took ibuprofen (400 mg), whereas those in group 2 received LLLT (808 nm, 200 mW, 2 J/cm RESULTS: The intensity of spontaneous and biting pain increased up to the first or second days following initial archwire placement and diminished to a negligible value by the seventh day. No significant difference was found between the study groups concerning spontaneous and biting pain at any timepoint of investigation (P > 0.05). CONCLUSIONS: With the protocols used in the study, low-level laser therapy and laser acupuncture therapy were as effective as ibuprofen and placebo laser treatment for pain reduction in orthodontic patients.

ZUSAMMENFASSUNG: ZIELE: Diese Studie verglich die Wirksamkeit von Low-Level-Lasertherapie (LLLT) und Laser-Akupunkturtherapie (LAT) bei der Schmerzreduktion nach dem Ersteinsatz von Bogendrähten. METHODEN: Die unizentrische, randomisierte, parallele, einfach verblindete klinische Studie. umfasste 60 Patientinnen, die zur Behebung von Zahnengständen 4 Prämolarenextraktionen benötigten. Die Probandinnen wurden randomisiert einer von 4 Gruppen zu je 15 zugeteilt. Nach Einsetzen des ersten kieferorthopädischen Bogendrahtes nahmen die Patientinnen in Gruppe 1 Ibuprofen (400 mg), während diejenigen in Gruppe 2 LLLT (808 nm, 200 mW, 2 J/cm ERGEBNISSE: Die Intensität von spontanen Schmerzen und Schmerzen beim Beißen stieg bis zum ersten oder zweiten Tag nach Einsetzen des Bogendrahtes an und verringerte sich bis zum 7. Tag auf einen vernachlässigbaren Wert. Zwischen den Studiengruppen wurde zu keinem der Bewertungszeitpunkte ein signifikanter Unterschied bei spontanen Schmerzen und Schmerzen beim Beißen festgestellt (p > 0,05). SCHLUSSFOLGERUNGEN: LLLT und LAT waren mit den in der Studie verwendeten Protokollen ebenso wirksam wie Ibuprofen und Placebo-Laser zur Schmerzreduktion bei kieferorthopädischen Patientinnen.
