Background and Aim: Nowadays using modern technology in human life, such as mobile phones and necessities of life, has increased and unavoidably exposed to ambient electromagnetic fields (EMF) generated from various electrical devices and from power transmission lines. The aim of our study was to see the effect of (EMF) on Anatomical & Histopathological of Gingival-epithelial tissue in rat. Materials and Methods: In this study 30 rat pups (age: 15weeks), randomly allocated into test group (n=15) and control group (n=15). The test group was exposed to 50 Hz EMF(80G) (non-ionizing radiation) during postnatal life (5 weeks) and (n=15) rat pups were kept free of radiation in control group, at the end of the 5th week of experiment the samples were collected from Gingival-epithelial tissue in whole rats (pups) in the experiment group. Results: This study indicated that experimental rats Gingival-epithelial tissue was found disrupted at various layers and due to the loss of collagen fibrils and the rates of apoptotic cells are increased in the test group (33±0/074) in compared with control group (12±0/044), (P 0/01). Conclusion: These results suggest that EMF exposure may cause profound changes in the gingival tissue and decreasing in its integument layers .Therefore exposure to EMF may result in pathological changes that lead to dental and gingival disorders and diseases.
