  Purpose

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.

Estimated Enrollment: 150
Study Start Date: August 1993
Detailed Description:

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.

Participants in the placebo group may be removed from study if bone loss exceeds 5% per year.

A study duration of 3 years is anticipated.
