Abstract
BACKGROUND:
To
compare the analgesic effect of anesthetic infiltration of lidocaine 2%
and low-level laser therapy (LLLT) by GaAlAs into tender points of
patients with orofacial pain and fibromyalgia (FM).
MATERIAL AND METHODS:
A
randomized clinical trial was performed with adults (N=66) that were
allocated into two groups (1:1): Group A received LLLT irradiation by
Diode Laser GaAlAs (780nm) with expositions twice a week during six
weeks and Group B was treated with anesthetic infiltration of lidocaine
2% without vasoconstrictor once a week for four weeks. The pain
assessment included the Visual Analogic Scale (VAS) and tenderness to
palpation.
RESULTS:
No
dropout and adverse effect was observed during the study. The pain
decreased significantly in each group after the treatment (p=0.0001,
β=1.0), even though no statistical difference was found between both
treatments (p=0.46, β= 0.82). The presence of tender points decreased
after both treatments, with responsively in some types of masticatory
muscles (p<0 .05="" a="" and="" both="" did="" effective="" except="" few="" improve="" muscle.="" not="" p="" patients="" perception="" posterior="" reported="" showed="" temporalis="" that="" the="" treatment="" treatments="" welfare.="" were="">
CONCLUSIONS:
The
LLLT by GaAlAs and anesthetic infiltration of lidocaine 2% were equally
effective to control orofacial pain in FM individuals.
