Exogenous progesterone short-termly affects the periodontal environment in perimenopausal women

This study aimed to evaluate the effects of exogenous progesterone in the periodontal environment of perimenopausal women.

Either with or without periodontitis, 100 perimenopausal women received 3 months of progesterone treatment, as well as age-matched 100 perimenopausal and 100 postmenopausal women without treatments were enrolled (N = 50). The gingival index (GI), probing depth (PD), clinical attachment level (CAL), and tooth mobility (TM), as well the gingival crevicular fluid (GCF) levels of IL-6 and TNF-α were analyzed.

Periodontitis showed higher GI, PD, and CAL than non-periodontitis at perimenopausal and postmenopausal periods. In women without periodontitis, the GI and PD, and the GCF levels of IL-6 and TNF-α were increased by 3 months of progesterone treatment, but recovered from the 6th month in the absence of progesterone. In women with periodontitis, only the PD was short-termly increased by progesterone treatment. For those without progesterone treatment, the GI, PD, and TM were not significantly different between perimenopausal and postmenopausal women either with periodontitis or not.

Exogenous progesterone short-termly exacerbated the inflammation and PD in perimenopausal women without periodontitis, and the PD in those with periodontitis.
