Laser Therapy vs. EGF Injection for Jaw Pain: A Clinical Trial
Objective
The goal of this study was to compare the effectiveness of Piano level laser therapy and epidermal growth factor (EGF) injection in relieving pain and improving function and quality of life for patients with myogenic temporomandibular disorder (TMD).
Study Design
We conducted a randomized clinical trial with 29 patients suffering from chronic myogenic TMD.
– **Group I:** 13 patients received Nd-YAG laser treatment (4 sessions, once a week).
– **Group II:** 14 patients received EGF injections.
We measured pain, jaw movement, and quality of life at various time points: baseline, 7, 14, and 21 days, as well as 1 and 3 months after treatment.
Results
Both treatments significantly reduced pain and increased pain-free jaw opening.
– **Group I** had a notable improvement in maximum jaw opening.
– Quality of life improved in both groups.
There was no significant difference between the two treatments regarding pain, jaw movement, or quality of life.
Conclusion
Both laser therapy and EGF injections are effective, affordable, and minimally invasive options for treating myogenic TMD without side effects.
Clinical Relevance
Myogenic TMD is a widespread health issue that causes significant pain and disability. Offering effective, non-invasive treatments can greatly benefit patients.
