Abstract

Objectives : To compare jaw bone density of young adults (control group) and post-menopausal women (experimental group) in periapical and panoramic film.
Materials and Methods : The bone mineral density values of lumbar and femur were measured by dual-energy X-ray absorptiometry and T scores of lumbar were obtained. T scores were classified into 3 group (T<-2.5, -2.5 Results . : There were significant differences in bone mineral density of lumbar and femoral neck between control and experimental groups. There were also significant differences in bone density of premolar and molar area of jaw between control and experimental groups by MANOVA test. When considered lumbar T variables, there was only difference in interdental bone density of maxillary molar area between control and experimental group, but there was interaction. Interdental bone density of experimental group was appeared higher in -1ST group and lower in T<-2.5 group than control group. There was significant difference in PMI between control and experimental group, but there was also interaction, thus, PMI of experimental group was appeared higher in -1Conclusion: There were significant differences of alveolar density and cortical bone thickness between young men and post-menopausal women in periapical and panoramic film. These differences were dependent on lumbar T.
