Effects of Extremely Low Frequency Magnetic Field on Pulp Tissue of Rats

Abstract

This study aims to investigate the effect of Extremely Low Frequency Magnetic Field (ELF-ME) on dental pulp of ovariectomized rats. About 75 female Wistar-albino rats were randomly divided into 5 groups: cage-control, ovariectomy, ELF-MF exposure, ELF-MF exposure with strontium ranelate treatments and ovariectomy application, ELF-MF exposure with ovariectomy application. All groups except cage-control and ovariectomy groups were exposed to 1.5 mT ELF-MF exposure throughout 6 months, 4 h a day. After all applications, pulp tissues of rat teeth were investigated under light microscope. Between the groups, histological differences in collagen fibrils, fibroblasts, blood vessels and odontoblasts that create the pulp were found. We concluded that osteoporosis affected the odontoblasts and fibroblasts in rat dental pulp, ELF-MF exposure did not resolve the histopathological effect due to osteoporosis but enhanced this pathological effect, strontium ranelate was more efficient to eliminate the effects of osteoporosis than ELF-MF application.
