This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. 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. There will be 40 subjects enrolled in this study. All subjects will receive surgical treatment. 20 subjects will receive FORTEO and 20 will receive placebo. Subjects will be assigned to study group randomly. Neither the subjects nor the clinicians will know whether the subject is receiving FORTEO or placebo. Patients will undergo routine periodontal treatment procedures including periodontal surgery. Starting from 3 days prior to surgery, all subjects will self-administer FORTEO or placebo for 6 weeks. Subjects will be trained for self-administration, a procedure similar to diabetic injections. Patients will also take Vitamin D and Calcium by mouth during this time. Study outcomes will be measured by blood collection; oral fluid sampling; oral x-ray and spine and hip bone density scan; routine periodontal examinations; and an oral health quality of life questionnaire. Patients of both genders and all ethnicities from age 30-75 years will be included in the study. All ethnicities are eligible for entry into study. No vulnerable populations will be included. Pregnant/breast-feeding women and women of childbearing potential on no contraception will be excluded from the study. Research records will not be linkable to the research subjects. Subjects will be randomly assigned to treatment arms and identified by initials and numbers. Informed consent forms will be used to obtain consent for participation in the study from all subjects prior to enrollment. The Principal Investigator or Co-Investigator will explain the details of study involvement and give subjects ample opportunity to ask questions. It is anticipated that patients on FORTEO will have greater regeneration with periodontal therapy as compared to control patients. '
