Abstract
Osteoporosis characterized by low bone mass/osteopenia can be identified using radiomorphometric indices in routine panoramic radiographs. This study estimates the prevalence of osteopenia in 50-80 years age group, using panoramic mandibular index (PMI), mental index (MI) and mandibular cortical index (MCI). PMI, MI and MCI were applied on 36 panoramic radiographs; MI and MCI were compared with PMI. The prevalence of osteopenia was 11.1% with PMI and 44.4% with MCI. Using MI, the prevalence was 2.8% and 33.3% with 3mm and 4.77mm threshold respectively. The prevalence of osteopenia detected was highest using MCI (44.4%). Considering PMI as gold standard, MI with 4.77 mm threshold showed better agreement with PMI.
Highlights
Panoramic radiographs of 36 patients panoramic radiographs have been suggested C1, C2 and C3 types (MCI), based on the were studied using panoramic mandibuly lar index (PMI), mandibular cortical index (MCI) and mental index (MI)
This insti- sidered as normal, C2 as osteopenia and C3 gorized into C1, C2 and C3 types of MCI, tution-based pilot study was undertaken to as osteoporosis.[7]
The prevalence of osteopenia was estimated in elderly males and females using three mandibular radiomorphometric indices, PMI, MI and MCI; the highest percentage of osteopenia was detected by MCI, and the least by MI
Summary
Panoramic radiographs of 36 patients panoramic radiographs have been suggested C1, C2 and C3 types (MCI), based on the were studied using PMI, MCI and MI. Dentists.[4] Various studies have reported mandible distal to the mental foramina when PMI was used, while it was 2.8%. The radiographs were cateosteopenia/osteoporosis.[4,5,6,7,8] this insti- sidered as normal, C2 as osteopenia and C3 gorized into C1, C2 and C3 types of MCI, tution-based pilot study was undertaken to as osteoporosis.[7] Since C3 (classified as and it was found that 55.6% (n=20) fell into estimate the prevalence of osteopenia in osteoporosis) may be considered as C1 category, 38.9% (n=14) into C2 and [page 124]
