ABSTRACT
By means of long term extremely low frequency magnetic field (ELF), this study examined the effect of long term magnethic field on rat calvarian and mandibular bone mass.
Fourty five female Spraque-Dawley rats were selected for the study. The rats were divided into 3 groups (n=15); ELF MF with 50Hz, 1.5mT was applied for 6 months, 4 hours/day. Total cranial and mandibular bone mineral density (BMD) and bone mineral content (BMC) of rats were determined by dual-energy X-ray absorptiometry (DXA; Discovery QDR series, Discovery A, Hologic, Inc.). Measurements were recorded for all groups before and after the applications, all data were collected and analyzed statistically.
The variations in Group 1, before and after the ELF MF applications with respect to BMC and BMD were considered significant (p<.01, p<.001). The variations in Group 2, that has bone loss with respect to BMC and BMD were considered not significant (p>0.05). The variations in control group, Group 3, with respect to BMC and BMD were considered significant (p<0.05).
