Salivary Calcium in Post-menopausal Women and Prevalence of Dental Caries

The presence of estrogen receptors detected through immunohistochemistry in the oral cavity plays a significant role in associating the effect of post-menopausal conditions to variations in the oral environment like salivary hypofunction, oral discomfort, and oral mucosal disorders. The vaginal mucosa and oral mucosa are similar histologically due to stratified squamous epithelium and desquamative growth pattern. Therefore, the variation in hormonal status in post-menopausal women may lead to the proliferation and maturation of oral epithelium in response to circulating estrogens. The keratinocytes and fibroblasts in the gingival tissues are majorly targeted by estrogen leading to periodontitis, fibroblastic hyperplasia, and desquamatic lesions. Therefore, it is a proven fact that gingiva is a traditional estrogen target, leading to the destruction of supporting structures of a tooth, causing periodontitis and thereby exposing tooth structure. Another primary oral manifestation in menopausal women is xerostomia/dryness of the mouth. The salivary components provide defense by maintaining the desired pH and decreasing the prevalence of caries, but estrogen levels directly decrease the salivary flow rate. Thus, the prevalent acidic pH causes demineralization and destruction of enamel, dentin making it more susceptible to dental caries.

A correlation between bone mineral density, salivary calcium levels, and estrogen levels is already established. Hence, the salivary calcium levels can indicate increased demineralization of tooth surface and osteoporosis in menopausal. Hence, the present focuses on estimating salivary calcium levels and their association with the prevalence of dental caries in post-menopausal women.
