Effect of Dry Needling on the Masseter Muscle in the Tinnitus Perception of Patients with Temporomandibular Disorder.

Objective: To evaluate the effect of dry needling on the masseter muscle in the perception of tinnitus in patients with temporomandibular disorder.

Methods: Twenty-five patients with tinnitus and muscular temporomandibular disorders were randomly assigned to groups study ( = 13) and control ( = 12). Three sessions of dry needling (study) and sham (control) were performed.

Self-ligating brackets do not reduce discomfort or pain when compared to conventional orthodontic appliances in Class I patients: a clinical study.

Objectives: To compare the intensity, location, and short-term impact of the periodontal discomfort/pain, as well as the related functional parameters of bite force and masticatory efficiency, between self-ligating and conventional orthodontic appliances.

Materials And Methods: In 20 patients referred for orthodontic treatment, samples were collected from the gingival sulcus to evaluate the level of substance P using enzyme-linked immunosorbent assay. Orthodontic devices were randomly bonded, with self-ligating appliances on one side and conventional brackets on the contralateral side.
