About
The investigators evaluated the effect of initial periodontal treatment on clinical findings and receptor activator of Nuclear Factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) in gingival crevicular fluid (GCF) of patients with osteoporosis under bisphosphonate therapy within 12 months' follow-up. Clinical recordings and GCF were obtained from postmenopausal women; with chronic periodontitis and osteoporosis (Group A, n=13), with chronic periodontitis and no osteoporosis (Group B, n=12), without chronic periodontitis and osteoporosis (Group C, n=12), systemically and periodontally healthy controls (Group D, n=10) at the baseline. Recordings were repeated at the 1st, 6th and 12th months in Group A, B and C. RANKL and OPG values were measured by enzyme-linked immunosorbent assays.
Full description
The study groups were selected from postmenopausal patients those referred to Department of Endocrinology, School of Medicine, Ondokuz Mayis University. Bone mineral density (BMD) measurements were performed by dual energy-X-ray absorptiometry from L1-L4 site of lumbar vertebra and/or femur (g/cm2). Osteoporosis was defined as T scores less than -2.5 at L1-L4, femur neck or total femur. Women with T scores less than -2.5 (groups A and C) were started on bisphosphonate treatment after their initial periodontal examination.
