Metodologia: Foram selecionadas 14 mulheres com DD usu芍rias de contraceptivos orais (CO), 12 mulheres sem DD usu芍rias de OC (controle); 12 mulheres com DD e ciclos menstruais regulares e 14 mulheres sem DD e ciclos menstruais regulares. O Research Diagnostic Criteria para Desordens Temporomandibulares diagnosticou o DD, e volunt芍rias sem dor foram selecionadas. Os movimentos mastigat車rios foram registrados usando um cinesi車grafo. Vari芍veis dependentes foram: amplitudes vertical, lateral e antero-posterior (mm), velocidade de abertura e fechamento (mm/s), sendo avaliadas nas 4 fases de 3 ciclos menstruais, identificado por teste ovulat車rio. Os dados foram submetidos ao teste de esfericidade de Mauchly, Proc Mixed para medidas repetidas e Tukey-Kramer (P ≒ 0,05). Resultados: Compara es entre as fases do ciclo menstrual n o mostraram diferen as nas amplitudes vertical (P=0,25), lateral (P=0,12), e antero-posterior (P=0,61), bem como na velocidade de abertura (P=0,57) ou fechamento (P=0,73). O uso OC e a presen a de DD n o influenciaram as vari芍veis (P>0,05). Conclus o: A flutua o hormonal n o influenciou o movimento mandibular mastigat車rio de mulheres com DD. Purpose: This study aimed to verify the influence of hormonal fluctuations on chewing movement in women with disc displacement (DD). Methods: Fourteen women with DD taking oral contraceptives (OC); 12 DD-free controls taking OC; 12 normally cycling women with DD; and 14 DD-free normally cycling women were included. The Research Diagnostic Criteria for Temporomandibular Disorders diagnosed DD, and subjects without pain were selected. Chewing movements were recorded using a kinesiograph. Dependent variables were: vertical, lateral, and anterior-posterior amplitudes (mm), opening and closing velocity (mm/s), which was evaluated in 4 phases of 3 menstrual cycles, identified by ovulation test. Data were submitted to Mauchly*s sphericity test, Proc Mixed for repeated measures, and Tukey-Kramer test (P ≒ 0. 05). Results: Comparisons among menstrual cycle phases showed no differences in vertical (P=0. 25), lateral (P=0. 12), and anterior-posterior amplitudes (P=0. 61); as well as opening (P=0. 57) or closing velocity (P=0. 73). The OC use or presence of DD did not influence the variables (P>0. 05). Conclusion: Hormonal fluctuation did not influence chewing mandibular movement of women with DD. %K ODONTOLOGIA %K MAND赤BULA - MOVIMENTOS %U http://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/10600/7681
