The trabecular pattern predicts the presence of osteoporosis just as well as age does. When combining the trabecular pattern with age, the sensitivity and specificity increased. Only the latter increase was statistically significant.
The recognition of a craniomandibular or cervical spinal pain is usually based upon the pain complaint of the patient, reported during an oral history, and the pain responses provoked in a clinical examination. Often used clinical tests are palpation, and function tests like dynamic/static tests or active movements. The relative importance of these tests for the recognition of the musculoskeletal pain is important. Therefore, it was the aim of the present study to determine which test, or combination of tests, best discriminates between persons with or without craniomandibular and/or cervical spinal pain complaints. Two hundred and fifty persons participated. From each person, a standardized oral history was taken. Then, in a randomized order and using a blind design, physical examinations of the craniomandibular system and of the neck were performed. Forward stepwise logistic regression analyses showed that the dynamic/static tests discriminated better between persons with and without pain complaints than the other tests did. In conclusion, in studies to the coexistence of craniomandibular and cervical spinal pain, it may be a good choice to base the recognition of these disorders on the pain complaints reported in the oral history which are verified by the pain response of the dynamic/static tests.
Objectives: A previous study showed that the trabecular pattern on dental radiographs correlates with femoral and spinal Bone Mineral Density (BMD). The objective of this study was to determine if the correlation is affected by size and location of the region of interest (ROI). Conclusions: This study shows that it is allowed to include parts of neighbouring teeth in the region of interest used to assess the trabecular pattern and predict BMD. This simplifies the process of selecting the ROI because no efforts have to be made to exclude neighbouring teeth.
MethodsCombining ROIs of lower and upper jaws improves the prediction of BMD significantly.
The measurements of the parameters used in this study are very reproducible. Therefore, the manual selection of the regions of interest does not introduce large amounts of noise. The imaging parameters potentially offer an accurate tool for the prediction of BMD values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
