Parathyroid hormone (PTH) has potent bone-building actions and has been approved for the treatment of osteoporosis as FORTEO by Eli Lilly & Co. Numerous studies have verified its effectiveness in increasing bone mass and potential for PTH to positively impact oral bone. The hypothesis of this study is that patients administered FORTEO along with periodontal (gum) surgery will respond more favorably than patients who receive placebo.
