Orthodontic intervention combined with myofunctional therapy increases electromyographic activity of masticatory muscles in patients with skeletal unilateral posterior crossbite.

Objective: The aim of this study was to evaluate the electromyographic activity of both the temporalis and masseter muscles and the mastication type of patients with skeletal unilateral posterior crossbite before and after orthodontic treatment and speech therapy.

Methods: A total of 14 patients with skeletal unilateral posterior crossbite (eight females and six males), between 6-13 years of age, underwent electromyographic evaluation of their masseter and temporalis muscles in mandibular rest, habitual mastication and isometry. The subjects were assessed with regard to mastication type before and after orthodontic treatment and speech therapy.

Videofluoroscopic evaluation of mastication and swallowing in individuals with TMD.

Unlabelled: To study mastication and swallowing disorders in patients with temporomandibular disorders (TMD).

Objective: To investigate mastication and swallowing disorders in patients with severe TMD referred to surgery.

Materials And Methods: Clinical and experimental study involving ten individuals with TMD submitted to deglutition videofluoroscopy.
