OBJECTIVES: I. Quantify periodontal alveolar bone loss rates in postmenopausal women.
II. Evaluate the effects of estrogen on alveolar bone loss rates in these patients.
III. Determine whether changes in periodontal bone mass relate to bone mass changes in other skeletal sites in these patients.
|Condition or disease||Intervention/treatment||Phase|
|Osteoporosis||Drug: conjugated estrogens Drug: Medroxyprogesterone||Phase 3|
PROTOCOL OUTLINE: This is a randomized, double-blind, placebo controlled study. Patients are randomly assigned to receive placebo or conjugated estrogens and, if no prior hysterectomy, medroxyprogesterone. Patients also receive calcium supplementation therapy daily for 3 years.

A study duration of 3 years is anticipated.
