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.

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.

Article Synopsis
  • Recent studies indicate that estrogen may help retain teeth, particularly in postmenopausal women, but the underlying mechanisms are not fully understood.
  • This study examined the relationship between estrogen use and dental health by analyzing data from 330 Japanese women, focusing on tooth retention and bone health metrics.
  • Findings suggest that while estrogen users tended to retain more posterior teeth over time, it may do so by enhancing the periodontal attachment rather than improving bone height or reducing bone porosity.

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.
