Abstract
This study was performed to assess the relationship between menstrual irregularity and dental pain or chewing discomfort in women before menopause, using nationally representative data. This study analyzed 4595 participants who were ≥19 years or older, and did not have missing values for outcome variables from the Korean National Health and Nutrition Examination Survey. Tooth pain was considered present if the participant felt throbbing discomfort, pain, or sensitivity when eating hot or cold food or drinking hot or cold beverages. Self-reported oral chewing discomfort was obtained. Adjusted odds ratios and their 95% confidence intervals for tooth pain in the individuals with menstrual cycle irregularity were 1.30 (1.05, 1.62) after adjustment for age, body mass index, drinking, smoking, income, exercise, stress, metabolic syndrome, and the frequency of tooth brushing. Adjusted odds ratios and their 95% confidence intervals for chewing discomfort in the individuals with menstrual cycle irregularity were 1.33 (1.03, 1.72) after adjustment. The association between menstrual irregularity and dental pain or chewing discomfort in women before menopause was proven—after adjusting for confounding factors—by multiple logistic regression analyses. Menstrual cycle irregularity may be considered a potential risk indicator for dental pain or chewing discomfort in Korean women before menopause.
Highlights
Menstrual cycles can be considered important indicators of health and fertility [1,2]
Women with long or highly irregular menstrual cycles have a significantly increased risk for developing type 2 diabetes mellitus [4], and the prevalence of type 2 diabetes is higher among women with a history of menstrual irregularity [5]
Body mass index, smoking, white blood cell count, and metabolic syndrome were significantly higher in participants with menstrual cycle irregularity
Summary
Menstrual cycles can be considered important indicators of health and fertility [1,2]. Previous studies have shown the association between menstrual cycle irregularity and systemic diseases. Menstrual cycle length has been suggested as a predictor of cardiovascular disease and a breast cancer risk factor [3]. It was reported that menstrual cycle irregularity can be considered a marker of metabolic disorders [6]. It has been shown that there is an association between menstrual cycle irregularities and periodontal treatment needs [2]. It was hypothesized that there is no significant association between menstrual irregularity and dental pain or chewing discomfort. This study was performed to assess the relationship between menstrual irregularity and dental pain or chewing discomfort in women before menopause using nationally representative data, and this is the first study to evaluate this topic
