The Relationship Between the Density of the Mandible and That of Post-Cranial Bone in Postmenopausal Women

摘要

Skeletal mass declines in all populations with age, and it is suggested that changes in oral bone may be linked to the status of the postcranial skeleton. Systemic loss of bone density leading to osteoporosis has also been suspected as a systemic risk factor for oral bone loss. The purpose of this study was to determine if the bone density of the mandible is related to the bone density of the spine and hip in postmenopausal women and if the mandibular density is declined with age and time of menopause and edentia. 52 edentulous postmenopausal women underwent assessment of postcranial and mandibular bone. BMD of the lumbar spine (L2-L4), the femoral neck (F) and the mandible (ramus M1, body M2) was determined by DEXA. Lower BMD M1 was found in osteopenic (n = 16 0.230 ± 0.31 g/cm2 p osteoporotic group (0.720 ± 0.59 p BMD L2-L4 (r = 0.242 p is significantly related to the density of the hip and lumbar spine in postmenopausal women and the mandibular body density declines with age, the occurrance of menopause and the time of edentia.
