Avaliação dos sinais e sintomas da disfunção temporomandibular em praticantes e não praticantes de CrossFit®

Abstract

Temporomandibular disorder (TMD) is a multifactorial disease that involves the temporomandibular joint (TMJ) and masticatory muscles. For a relevant and accurate analysis, making use of diagnostic criteria is essential, with this, the RDC / TMD was used in this study, which is a well-defined and reproducible internationally validated questionnaire. There are few studies that present data on the prevalence of TMD in sports, especially in CrossFit® practitioners, which in turn is the fastest growing sport modality in the world, consisting of a combination of various exercises, such as running, indoor rowing, swimming, weightlifting, gymnastic exercises, mobility, among others. Thus, the objective of this study was to verify the orofacial characteristics of CrossFit® and sedentary practitioners, diagnosed or not with temporomandibular disorders. This work is a non-randomized, prospective, descriptive, double-blind clinical study, in which 77 individuals underwent a clinical examination of the RDC / TMD and were divided into four parallel groups, namely: sedentary without TMD G1 (n = 16), sedentary with TMD G2 (n = 16), practitioners with TMD G3 (n = 25) and practitioners without TMD G4 (n = 20). The study showed 80 significant results by the Kruskall-wallis test, with p≤0.05, there was significance in the palpation of the temporal, masseter and digastric muscles, in addition to significant results on the presence of noises in the opening and lateral excursions and pain complaint. The practice of CrossFit® did not have a complementary potential in reducing signs and symptoms of TMD, given the similarity of painful responses between the groups affected by TMD.
