Interfaces between Orthodontics and Orofacial Motricity: In Which Situations the Sciences Find Each Other?

Introduction: The interdisciplinarity between phonoaudiology, in the scope of the orofacial motor, and dentistry, in the scope of the orthodontics, is attested by many cases when these two sciences need to interact to development adequacy and overcoming of the stomatognathic system. Although objects of distinct study, once the acting of speech is more centered in the form adequacy towards the functions of breathing, chewing, swallowing, and speech, whereas dentistry is concerned more specifically with the correction of dentofacial anomalies, they need to work together in many situations, in order to promote better diagnosis. Studies show that interdisciplinary work offer more effective treatments and better quality of life for patients. Objective: We propose a literature review, which aimed to strengthen the knowledge that must exist between the speech therapy and the dentistry, pointing the subjects that are more relevant and approximate these two specialties. Material and Methods: Through online search by means of common terms to both areas under study, were selected texts in Portuguese, English, and Spanish, after complete read, whenever attestation interdisciplinary character of the article. Conclusion: A total of 110 texts, between the years 1907 and 2013 were selected. According to the analysis of the texts, nine topics were identified where these two areas interconnect: breastfeeding, deleterious oral habits, malocclusion, temporomandibular disorders, orthognathic surgery, oral breathing and sleep apnea, cleft lip and palate, facial esthetics, and orthodontic treatment. It concludes the increasing need to approximate these two areas, looking complementation theoretical and teamwork. Keywords: interdisciplinarity, stomatognathic system, quality of life.
