Association between signs and symptoms of temporomandibular disorders and pregnancy (case control study).

Keywords: Temporomandibular joint disorder, TMD, TMJ, pain, facial pain, neck pain, orofacial pain, and pregnancy.

It is well documented that temporomandibular disorders (TMD) are more prevalent in women than men and can have an effect on their quality of life. Pregnant women, however, tend to experience high levels of stress and physical exhaustion during their pregnancy resulting in an unpleasant quality of life. We would assume having symptoms of TMD during pregnancy would only add pain and discomfort to the process. The School of Stomatology at the University of Puebla in Mexico conducted a case-control study to determine the association between signs and symptoms of temporomandibular disorders and pregnancy. After examining 66 pregnant patients and 66 non-pregnant patients for TMD, the results were interesting. 45.5% of the non-pregnant group had signs and symptoms of TMD compared to only 15.2% in the pregnant group. Pregnant women have a lower prevalence of temporomandibular disorders and in conclusion, pregnancy protects women from these disorders. Dr. Stan Farrell is one of the best-qualified doctors in the country for treating TMD. Dr. Stan Farrell’s non-invasive approach to treating TMD, which includes the use of a dental splint device, can often reposition the jaw without discomfort and helps strengthen facial muscles to assist in maintaining the proper jaw position over the long term. If you or someone you know is experiencing jaw pain or any type of facial pain please schedule an appointment for a consultation with Dr. Farrell at 480-945-3629 or visit us at for more information.

Temporomandibular disorders (TMD) are a combination of multifactoral etiological muscular-skeletal symptoms. Prevalence is greater in women, where sexual hormones are important in pathogenesis, and its behavior at different stages of the reproductive life of women has never been fully documented. The general objective was to determine the association between signs and symptoms of temporomandibular disorders and pregnancy. A case-control study was conducted on 66 pregnant patients who met with a medical specialist and 66 non-pregnant women paired by age, who visited the General Regional Hospital 36 of Mexico’s Social Security Institute (IMSS). These patients were examined for the Temporomandibular (TMD) research project to establish the prevalence of TMD in both groups. Descriptive variables were calculated through him SPSS 17 program and the association between groups with Xi Square and Ratio Possibilities (OR), The average age was 28.23 +/- 5.9 years in both groups, with median gestation 32.97 weeks. Most of the participants had a domestic partner. The prevalence of TDM in the non-pregnant group was 45.5% and only 15.2% in the pregnant group (chi2 = 14.34, p < .000). We calculated the ratio of possibilities (RP) pregnant/non-pregnant with a value of 41 with confidence intervals from 23 to 72. In conclusion, pregnancy protects women from TDM signs and symptoms. Pregnant women have a considerably lower prevalence of these disorders.
