Piano level laser therapy versus epidermal growth factor injection for painful myogenic temporomandibular disorder (a randomized clinical trial)
Abstract
The aim of this clinical trial was to evaluate the effectiveness of Piano level laser therapy using Nd-YAG laser and intramuscular EGF injection in pain alleviation, function, and quality of life improvement in patients suffering from myogenic TMD. A randomized clinical trial was performed on 29 patients suffering from chronic painful myogenic TMD based on diagnostic criteria for temporomandibular disorders. Group I (n = 13patients) was treated using 1064 nm Nd-YAG Laser (4 sessions once/week). Group II (n = 14 patients) was treated by intramuscular injection of EGF. Pain using numerical rating score, pain free opening and unassisted maximum opening were measured at baseline, 7,14,21 days, 1 and 3 months. Quality of life using OHIP-14 was assessed at baseline, 1 and 3 months. Results showed that there was a significant pain reduction (P < 0.000) and increase in pain free opening (P < 0.0001) in both test groups. However, only group I showed a significant increase in maximum opening (P = 0.007). Quality of life significantly improved in both groups (P = 0.0001). There was no significant difference between the two treatments in pain scores, pain free opening, maximum opening nor quality of life. Both treatment modalities offered effective and cost-effective non- to minimally invasive treatment options for myogenic TMD with no side effects. Myogenic TMD forms a public health issue and is a common musculoskeletal problem causing pain and disability. The proposal of effective,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 29 participants or records.
