Evaluation of Low Energy Level Laser Biostimulation at Different Energy Densities in the Treatment of Temporomandibular Joint Irregularities: A Retrospective Study
The Study Was Conducted by Retrospectively Analysing the Files of Patients Who Presented With Temporomandibular Joint Disorder (TMD) and Underwent LLEL Treatment. Patients Were Divided Into Myalgia, Disc Displacement With Reduction and Follow-up Groups. In Our Study, GaAl-As Diode Laser (EzLase 940, Biolase Technology, Inc. 4 Cromwell Irvine, USA) for Lowlevel Laser Treatment Was Applied for 1 Minute to Subgroup 1 (940 nm, 1. 5 W, 90 J, Continuous), Subgroup 2 (940 nm, 3 W, 180J, Continuous) and Subgroup 1 (940 nm, 1.5 W, 90J, Continuous) and Subgroup 2 (940 nm, 3 W, 180J, Continuous).

Brief Summary
This clinical study aimed to evaluate the effectiveness of low-level laser therapy in patients with temporomandibular disorders (TMD), specifically disc displacement with reduction and myalgia. The study compared laser therapy with a soft diet approach to determine whether laser treatment provides additional benefits in reducing pain and improving jaw function

Outcome Measures
Primary Outcomes (1)
Change in temporomandibular pain intensity measured by the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up
Change in temporomandibular pain intensity was assessed using the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up. The Visual Analog Scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores represent greater pain severity.

Low Level Laser Therapy
ACTIVE COMPARATORParticipants in this group received low-level laser therapy applied to the temporomandibular joint region according to the predefined treatment protocol. Laser therapy was administered for 2 minutes per joint over 9 treatment sessions. Patients were also advised to follow a soft diet during the treatment period.
soft diet group
OTHERSoft Diet Group: Participants in this group did not receive laser therapy and were instructed to follow a soft diet during the study period. This group served as the comparison group for evaluating treatment outcomes.
Interventions
Participants received low-level laser therapy applied to the temporomandibular joint region in addition to soft diet recommendations. Treatment was performed in 9 sessions according to the predefined laser protocol. Participants followed a soft diet regimen without receiving laser therapy and served as the comparison group.
Participants in this group did not receive laser therapy and were instructed to follow a soft diet during the study period. This group served as the comparison group for evaluating treatment outcomes.
Eligibility Criteria
You may qualify if:
