Abstract
Anterior disc displacement is a condition when the articular disc is in the anterior normal position. Epidemiological research shows that the prevalence of TMD is higher in women than in men. Women have a dominant hormone that is not owned by men, the hormone estradiol. Estrogen receptors and the hormone progesterone are found in articular joints in humans. Joint structure, extracellular matrix remodeling, and bone volume modification can be affected by sexual hormones. It was thought to cause changes in connective tissue in the TMJ structure. This study aims to determine the effect of the level of the hormone estradiol in menopausal women on anterior temporal disc displacement of the temporomandibular joint. Subjects were 40 postmenopausal women who were examined for temporomandary joints. The diagnosis of anterior disc displacement was made using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD) method. Subjects were grouped into subjects with normal tempromandibular joints and subjects with anterior disc displacement. Estradiol hormone was examined by the immunoassay method. This study’s conclusion is estradiol hormone in menopausal women with anterior disc displacement is higher than menopausal women without anterior disc displacement.

Anterior disc displacement is an intracapsular dysfunction that causes disc and articular surfaces degeneration [1]
This study aims to determine the effect of the level of the hormone estradiol in menopausal women on anterior temporal disc displacement of the temporomandibular joint
The average estradiol levels in subjects without anterior disc displacement was 32.14 with standard deviation of 22.51 (Figure 1). This showed that the level of estradiol in subjects with anterior disc displacement was higher than the value of estradiol in subjects without anterior disc displacement
Summary
Anterior disc displacement is an intracapsular dysfunction that causes disc and articular surfaces degeneration [1]. The first sign of disc displacement is that the patient complains of joint noise or clicking. This condition is caused by stretching of the posterior attachment and the disc being in the anterior condyle at the mouth opening [2, 3, 4]. Research shows the prevalence of TMD in women 2-5 times higher than in men. Women have a special hormone that is not owned by the pira, the hormone estradiol. The hormone estradiol is one of the most important types of estrogen [5, 6]
