ABSTRACT

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.
RESUMO

OBJETIVO:

Este estudo objetivou verificar a influência das flutuações hormonais nos movimentos mastigatórios de mulheres com deslocamento de disco (DD).

METODOLOGIA:

Foram selecionadas 14 mulheres com DD usuárias de contraceptivos orais (CO), 12 mulheres sem DD usuárias 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 voluntárias sem dor foram selecionadas. Os movimentos mastigatórios foram registrados usando um cinesiógrafo. Variáveis ​dependentes foram amplitudes vertical, lateral e ântero-posterior (mm), velocidade de abertura e fechamento (mm/s), sendo avaliadas nas 4 fases de 3 ciclos menstruais, identificado por teste ovulatório. Os dados foram submetidos ao teste de esfericidade de Mauchly, Proc Mixed para medidas repetidas e Tukey-Kramer (P ≤ 0,05).

RESULTADOS:

Comparações entre as fases do ciclo menstrual não mostraram diferenças nas amplitudes vertical (P = 0,25), lateral (P = 0,12), e ântero-posterior (P = 0,61), bem como na velocidade de abertura (P = 0,57) ou fechamento (P = 0,73). O uso OC e a presença de DD não influenciaram as variáveis (P > 0,05).

CONCLUSÃO:

A flutuação hormonal não influenciou o movimento mandibular mastigatório de mulheres com DD.
