Visual assessment of the mandibular cortex on panoramic radiographs to identify postmenopausal women with low bone mineral densities.

Objective: The purpose of this study was to determine whether simple visual estimation of the mandibular inferior cortex width on panoramic radiographs is useful for identifying postmenopausal women with low skeletal bone mineral density (BMD).

Study Design: Panoramic radiographs were made on 100 women aged 50-84 years who also had BMD assessment of the lumbar spine and femoral neck by dual-energy x-ray absorptiometry. The panoramic images were examined twice by 4 observers to evaluate the thickness of the mandibular inferior cortex.

Relationship between self-reported periodontal status and skeletal bone mineral density in Japanese postmenopausal women.

Objective: Several investigators have linked periodontal disease progression and low skeletal bone mineral density in postmenopausal women. However, little is known about whether self-reported periodontal status is the reflection of skeletal bone mineral density. We investigated whether self-reported poor periodontal status is associated with low skeletal bone mineral density in postmenopausal women.

Tooth loss is associated with an increased risk of hypertension in postmenopausal women.

Tooth loss has been associated with an increased risk of vascular diseases such as coronary heart disease and cerebrovascular disease. Little is known whether hypertension is an important factor linking 2 phenomena in postmenopausal women. We compared an incidence of hypertension and traditional risk factors for vascular diseases between 2 age-matched groups: 67 postmenopausal women with missing teeth and 31 without missing teeth.
