Abstract:
Objective To investigate the mandibular bone mineral density(BMD)change of senile osteoporosis patients and the relationship between the mandible bone loss and systemic bone loss.Methods Forty senile osteoporotic patients(group A),40 non-osteoporosis control elders(group B)and 40 healthy youths(group C)were included in this study.Standard digital panoramic tomography(SDPTG)was taken for each participant.Cortical width(CW),panoramic mandibular index(PMI),alveolar bone density and alveolar bone height were measured on the SDPTG.Lumbar and hip BMD were measured with dual energy X-ray absorptionmetry(DXA).Results Close relationship was found between CW(3.57±0.82)and systemic BMD for osteoporosis patients(P＜0.05).All the SDPTG indices including CW,PMI,alveolar bone density and alveolar bone height were different for osteoporosis patients from the healthy youths(P＜0.05).The osteoporosis patients had thinner CW(3.57±0.82)and smaller PMI(0.29±0.06)than non-osteoporosis control elders(CW:4.07±0.75,PMI:0.32±0.07,P＜0.05).The alveolar bone density (105.40±20.48)and alveolar bone height(10.42±1.82)of the non-osteoporosis control elders reduced compared with the healthy youths(alveolar bone density:117.10±22.23,alveolar bone height:11.69±1.63,P＜0.05).Conclusions The senile osteoporotic patients had significant mandibular cortical bone loss.
