Impact of Hormones and Lifestyle on Oral Health During Pregnancy: A Prospective Observational Regression-Based Study.

Background and Objectives: This study explores the impact of hormonal fluctuations during pregnancy and lifestyle factors on stomatognathic system (SS) health. The aim is to determine how pregnancy-related hormonal changes and oral hygiene behaviors affect the onset of stomatognathic issues, such as gingival inflammation (GI) and dental erosion (DE). Materials and Methods: A prospective, observational study was conducted with 100 pregnant women, divided into two groups: Group A (60 women with significant stomatognathic alterations) and Group B (40 women without such alterations). Multiple regression analysis was used to evaluate the influence of hormonal levels, oral hygiene habits, and vomiting episodes on stomatognathic health. Results: Age and socioeconomic status showed no significant association with stomatognathic health (p > 0.05). In contrast, elevated levels of estrogen (p = 0.001) and progesterone (p = 0.003) were significantly linked to the severity of stomatognathic changes. Oral hygiene habits also had a statistically significant impact (p = 0.02), while vomiting frequency was not an important factor (p > 0.05). Conclusions: Hormonal changes during pregnancy, particularly increased estrogen and progesterone levels, are key predictors of stomatognathic health. These findings suggest that while oral hygiene is important, hormonal fluctuations play a dominant role in influencing stomatognathic system (SS) health during pregnancy.
