RESUMO
This review was conducted by three investigators to assess the scientific evidence and eff ectiveness of various electro physical modalities in the treatment of temporomandibular joint (TMJ) disorders. This review was conducted by three investigators. The databases of PubMed, Science direct, Cochrane clinical trials register (June 1994-Jan 2013) were electronically searched for the key terms TMJ disorders with low-level laser therapy (LLLT), iontophoresis, phonophoresis, therapeutic ultrasound, transcutaneous electric nerve stimulation, microcurrent electrical nerve stimulation. The retrieved titles were thoroughly evaluated, and full text was obtained. Based on the inclusion and exclusion criteria the selected studies were assessed for the quality evidence of the trails using the Grade Pro 3.6 version software and summary of finding table was generated. Of 1544 titles, 28 full text publications, which were eligible for this review were included, and 15 randomized placebo controlled trials that were fulfilling the set criteria. Out of 15 studies 10 are performed on LLLT, 2 on iontophoresis, 1 on pulsed radiofrequency energy, 1 on cathodal high voltage electric stimulation and 1 on laser acupuncture. LLLT is the extensively practiced electrophysical treatment modality with the moderate quality of evidence. Electrophysical modalities are helpful as adjuvant in the treatment of TMJ symptoms. However, there are no evidences to conclude that a single electrophysical modality is beneficial over the other in the temporomandibular disorders management.
