Interdisciplinary diagnostic research for identification of brushism

Introduction: Bruxism is defined as a repetitive activity of the jaw muscles, characterized by clenching, grinding or clenching the teeth and / or tightening or pushing the jaw, with a strong impact on the quality of sleep and life of patients. Objective: Investigate the prevalent signs of bruxism in the sample studied through the cooperation of an interdisciplinary team in the areas of Speech Therapy and Dentistry, applying questionnaires, for the diagnosis of bruxism, differentiating from TMD. Material and Methods: Twenty individuals with major complaint of bruxism who were not previously treated participated in the study and were submitted to the RDC / DTM questionnaire (Research Diagnostic Criteria for Temporomandibular Disorders: Axis II) with positive responses to stress, anxiety, sleep disorders and sleep bruxism. ; ProDTMMulti questionnaire, which is a protocol for the determination of signs and symptoms of temporomandibular dysfunction (TMD) for multiprofessional centers, the AMIOFE (Orofacial Myofunctional Assessment with Score) protocol, Helkimo index or Craniomandibular Clinical Dysfunction (IDCCM) with Mandibular Mobility Index ( IMM) and OHIP 14 (Negative Impact on Quality of Life [Qol]). Results: Regarding the assessment of OHIP 14, physical pain and psychological discomfort had major negative impacts on QoL. In the RDC / DTM and ProDTMMulti, most of the sample reported head and face pain, TMJ cracking, teeth grinding, tooth clenching, physical tiredness, and ringing in the ear, which is in agreement with OHIP 14 in the correlation physical domain and psychological disorders. Regarding the IDCCM and IMM presented mild to severe dysfunction, without normality. In AMIOFE the main altered stomatognathic function was chewing and mandibular noises. Conclusion: It was concluded that subjects of the sample with symptoms of bruxism showed correlations with morphological and functional alterations of the stomatognathic system, especially with mastication and TMD.
