Implicações na mastigação ocasionadas pela distonia oromandibular: revisão integrativa

Abstract

Oromandibular dystonia (DOM) is described as a focal dystonia involving the masticatory or lingual muscles, with the following subdivision: jaw closing dystonia, jaw opening dystonia, jaw deviation dystonia, protrusion dystonia. jaw, lingual dystonia or even the union of these subtypes. Objective: To investigate whether there are limitations and impacts on chewing in patients diagnosed with DOM. Method: This is an integrative literature review. The search for periodicals listed in the databases was adopted as an information gathering instrument: Bireme, Academic Google, Lilacs, Pubmed and Scielo. Because the theme is little explored, the research was carried out without a defined time frame. Results: 12 articles were chosen to be used in the research. Among the most frequent findings were: inaccuracy in chewing, inability to bite, uncoordinated jaw and lingual movements, increased strength to keep the mouth closed, dental friction and limited mouth opening. Such changes generate an increase in masticatory cycles, excessive force during mastication, inefficiency in grinding food from tooth friction and limited mouth opening, inability to maintain a diet with solid texture foods, pain and discomfort mainly arising from tongue ulcers caused by the uncoordinated movements of this organ and weight loss. Conclusion: It is therefore concluded that oromandibular dystonia is responsible for triggering changes that compromise chewing, in addition to other functions of the stomatognathic system.
