Human mandibular trabecular bone density correlation with mechanical strength: implications for implant dentistry.

Purpose: The prognosis of a dental implant depends on the mechanical properties of the bone. The preoperative diagnosis of bone quality has become more important, because the immediate loading procedure is now widely used, and a firm initial stability is required. Quantitative computed tomography (QCT) is an effective method of determining selectively the bone mineral density (BMD) of the trabecular bone mostly responsible for the survival of the implant.

En Balance participants decrease dietary fat and cholesterol intake as part of a culturally sensitive Hispanic diabetes education program.

Purpose: The purpose of this study was to assess dietary intake habits of Mexican American Hispanic adults participating in the En Balance diabetes education program.

Methods: En Balance is a 3-month culturally sensitive diabetes education intervention for Spanish-speaking Hispanics. Of the 46 participants enrolled, 39 mainly Mexican American Hispanic adults with type 2 diabetes completed the En Balance program.

Bone density assessments of dental implant sites: 2. Quantitative cone-beam computerized tomography.

Purpose: Bone density was evaluated in designated implant sites using a novel volumetric computerized tomographic device. Those measurements were then compared with traditional quantitative computerized axial tomography and subjective bone density evaluation.

Materials And Methods: Sixty-three potential sites for implant placement in jaws from 9 human cadavers were used.

Aortic calcification and the risk of osteoporosis and fractures.

We investigated the relation between computed tomography measures of aortic calcification and values for bone density and the number of fragility fractures in 2348 healthy, postmenopausal women. To determine whether increases in vascular calcification and bone loss progress in parallel, baseline values were compared with measurements obtained 9 months to 8 yr later in a subgroup of 228 women. Of the 2348 subjects studied, 70% had osteoporosis, 30% had at least one vertebral fracture, and 9% had at least one hip fracture.

Bone density assessments of dental implant sites: 1. Quantitative computed tomography.

Purpose: This study was designed to evaluate variations of bone density in designated implant sites using quantitative computed tomography (QCT) and to compare the QCT measurements to subjective evaluation of bone density.

Materials And Method: Sixty-two designated implant sites in jaws of 9 human cadavers were used. Indicator rods, 2 mm in diameter, were placed in all sites.
