Correction to: Photobiomodulation versus light-emitting diode (LED) therapy in the treatment of temporomandibular disorder: study protocol for a randomized, controlled clinical trial.

After publication of our article [1] we became aware that several sections of text in our Methods section were copied from a previously published article [2].

After publication of our article [1] some questions were raised by a reader. We are grateful to the Editors-in-Chief for inviting Anne-Marie Glenny (Division of Dentistry, University of Manchester) to assess these questions, our responses and our published article. As a result we are publishing this Erratum to clarify various points. These are as follows:

We appreciate that the title of our article does not clearly describe our protocol. Instead of “Photobiomodulation versus light-emitting diode (LED) therapy in the treatment of temporomandibular disorder: study protocol for a randomized, controlled clinical trial” a more appropriate title would be: “Photobiomodulation with laser versus photobiomodulation with light-emitting diode (LED) in the treatment of temporomandibular disorder: study protocol for a randomized, controlled clinical trial”;

We would like to add that the sequence generation to randomize patients will be computer generated;

We would like to make it clear that our primary outcome is pain, evaluated with a visual analog scale (VAS).
