Abstract

Objective: 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.

Materials And Methods: 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: 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.

Conclusion: Both treatment modalities offered effective and cost-effective non- to minimally invasive treatment options for myogenic TMD with no side effects.

Clinical Relevance: Myogenic TMD forms a public health issue and is a common musculoskeletal problem causing pain and disability. The proposal of effective, non-invasive, and affordable treatment options can help solve this issue.
