“…Previous reports have indicated that as with other osteoporotic bones, there are negative effects on implant treatment in the socket of an extracted tooth, including a decrease in the rate of bone formation, alveolar bone interdental bone thickness, and in the density and thickness of the mandibular inferior cortex (18)(19)(20).…”

“…Karayianni et al 13 found a correlation between mandibular cortical width (MCW) on dental panoramic radiographs and DXA T-scores. In another study, the coarseness of alveolar bone trabeculation was found to be an indicator of BMD in the forearm, 15 while another study found that the maxillary alveolar bone density was an indicator of bone density at all other sites, including the anteroposterior lumbar spine and lateral lumbar spine. 16 Therefore, dental panoramic radiographs could provide a convenient, affordable source of screening for osteoporosis with a lower radiation exposure for those patients who might not otherwise have access to conventional methods.…”

Purpose-To evaluate the dental and periodontal health of adolescents and young women with restrictive anorexia nervosa (AN), and relationship between bone mineral density (BMD) assessed by dual energy X-ray absorptiometry (DXA) and dental radiographs.Study Design-Twenty-three young women, median age 17.6 years (range 14.4-27.2), were studied within three months of entering a clinical trial. DXA BMD measurements were obtained and subjects underwent a comprehensive dental examination, including panoramic and bitewing dental radiographs. Three observers assessed mandibular cortical width (MCW) in the mental foramen region on panoramic radiographs.Results-Dental findings included very good to excellent oral hygiene. Gingival recession was evident in 10 participants (43%). Dental erosion was not seen and the mean decayed missing or filled teeth (DMFT) was 8.6. There was a weak positive correlation between BMD by DXA and MCW on radiographs.Conclusions-We report dental manifestations associated with restrictive AN, and the association between bone assessments by DXA and dental radiographs in this patient group. Despite subnormal DXA measurements in most patients, essentially all adolescents had a normal dental examination. Dental providers should be cognizant of the fact that many patients with eating disorders may not display the "classic" findings reported in the literature.

“…Visual assessment of the trabecular pattern in intra-oral radiographs is a method to identify women at risk of having osteoporosis. Dense trabeculation is a strong indicator of healthy bone, whereas sparse trabeculation is a sign of osteoporosis [18][19][20].…”

Objective: In diagnostic imaging; human perception is the most prominent, yet least studied, source of error. A better understanding of image perception will help to improve diagnostic performance. This study focuses on the perception of coarseness of trabecular patterns on dental radiographs. Comparison of human vision with machine vision should yield knowledge on human perception. Method: In a study on identifying osteoporotic patients, dental radiographs were made from 505 post-menopausal women aged 45-70 years. Intra-oral radiographs of the lower and upper jaws were made. Five observers graded the trabecular pattern as dense, sparse or mixed. The five gradings were combined into a single averaged observer score per jaw. The radiographs were scanned and a region of interest (ROI) was indicated on each. The ROIs were processed with image analysis software measuring 25 image features. Pearson correlation and multiple linear regression were used to compare the averaged observer score with the image features. Results: 14 image features correlated significantly with the observer judgement for both jaws. The strongest correlation was found for the average grey value in the ROI. Other features, describing that osteoporotic patients have fewer but bigger marrow spaces than controls, correlated less with the sparseness of the trabecular pattern than a rather crude measure for structure such as the average grey value. Conclusion: Human perception of the sparseness of trabecular patterns is based more on average grey values of the ROI than on geometric details within the ROI.
