Estrogen replacement therapy (ERT) is linked to better tooth retention in elderly women. ERT use reduces the risk of edentulism, preserving natural teeth longer.

Area of Science:

  • Gerontology
  • Oral Health
  • Endocrinology

Background:

  • Tooth loss is a significant concern for elderly populations.
  • Estrogen replacement therapy (ERT) has been studied for various health benefits in postmenopausal women.

Purpose of the Study:

  • To investigate the association between ERT and tooth retention.
  • To determine if ERT use lowers the risk of edentulism in elderly women.

Main Methods:

  • Analysis of data from 488 women (aged 72-95) in the Framingham Heart Study.
  • Recording of remaining teeth and history/duration of ERT use.
  • Exclusion of third molars from analysis.

Main Results:

  • ERT users had more teeth remaining compared to non-users, even after controlling for confounding factors.

  • Duration of ERT use was a significant predictor of tooth retention; longer use correlated with more teeth.
  • Increased duration of ERT was associated with a reduced odds of being edentulous.

    • Conclusions:

    • ERT appears to protect against tooth loss in elderly women.
    • Estrogen use is associated with improved tooth retention, particularly for non-molar teeth.
