Abstract
"Temporomandibular disorders (TMD) are a combination ofmultifactoral etiological muscular-skeletal symptoms. Preva-lence is greater in women, where sexual hormones are importantin pathogenisis, and its behavior at different stages of the repro-ductive life of women has never been fully documented.The general objective was to determine the association between signsand symptoms of temporomandibular disorders and pregnancy.A case-control study was conducted on 66 pregnant patients whomet with a medical specialist and 66 non-pregnant women pairedby age, who visited the General Regional Hospital 36 of Mexico’sSocial Security Institute (IMSS). These patients were examined forthe Temporomandibular (TMD) research project to establish theprevalence of TMD in both groups. Descriptive variables werecalculated through him SPSS 17 program and the associationbetween groups with Xi Square and Ratio Possibilities (OR),The average age was 28.23 ± 5.9 years in both groups, withmedian gestation 32.97 weeks. Most of the participants had adomestic partner. The prevalence of TDM in the non-pregnantgroup was 45.5% and only 15.2% in the pregnant group(X2=14.34, p<.000). We calculated the ratio of possibilities(RP) pregnant/non-pregnant with a value of 41 with confidenceintervals from 23 to 72.In conclusion, pregnancy protects women from TDM signs andsymptoms. Pregnant women have a considerably lower preva-lence of these disorders".
