研究发现女性排卵期齿龈发炎的情形有所增加
研究者发现,女性在排卵期可能会出现齿龈发炎升高情形;而在经期之前,发炎会减轻;然后在经期间,炎症情况会进一步减轻。
以色列蓝邦医学中心和以色列技术学院医学部的马奇太(Eli Machtei)博士,率团队对15名20至50岁、每年进行数次定期牙齿清洁的女性进行了调查。在每次进行牙齿清洁时,这些女性都处于月经周期的不同阶段。
研究者在《牙周病学杂志》(Journal of Periodontology)上撰文报告说,齿龈发炎的程度会随月经周期发生变化,但牙斑和其他体现齿龈健康的情况不会随之变动。
研究人员表示,女性在经期前或经期中的几天常会出现口腔不适的症状——这时正是她们齿龈发炎情形消退的时候。
美国牙周病学会(American Academy of Periodontology)主席雷特曼(Michael Rethman)博士表示,女性体内的激素含量在一个月中会有所波动,而这样的变化可能会通过对血管、白细胞或免疫系统的作用,而影响齿龈发炎。
The Effect of Menstrual Cycle on Periodontal Health.
Background: Fluctuation in estrogen/progesterone levels has been shown to affect the periodontium. The effects of pregnancy, prepuberty, and oral contraceptives on gingival health has been studied extensively, with gingival scores reported to be higher, in most instances, than in controls. Fluctuation in steroid sex hormone is also noticeable through women's menstrual cycle. Many women report an increase in gingival inflammation and discomfort associated with their menstrual cycle, most commonly around the menses period. However, this well-known phenomenon has never been studied. The purpose of this longitudinal, prospective study was to compare the periodontal status of premenopausal women at different times during their menstrual cycle. Methods: Eighteen premenopausal women, enrolled in our maintenance program, were recruited. Clinical examination was performed before the recall visit at three different time points in their menstrual cycle: ovulation (OV), premenstruation (PM), and menstruation (M). Plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment level (CAL) were examined around the Ramfjord index teeth. Analysis of variance, with Scheffe modification, was used to determine differences between the menstrual time points. Results: Several women in this study reported appreciable oral symptoms just before or during menses. Mean PI (0.85 ± 0.06) was almost identical at all time points. Despite this, GI was significantly higher (P = 0.0245) in OV (0.54 ± 0.07) and in PM (0.5 ± 0.08) than in M (0.38 ± 0.07). Mean patient's PD (2.22 ± 0.08 mm) and CAL (2.92 ± 0.15 mm) was not significantly different between examinations. Conclusions: We observed changes in gingival scores during the menstrual cycles of periodontally healthy women. These changes need to be addressed when analyzing data from epidemiological and treatment studies in premenopausal women.
