Abstract

Objectives: To evaluate the effect of exposure to Wi-Fi signals, LTE mobile networks and MRI on the microleakage of amalgam. Method: Standard class V cavities were prepared on the buccal surfaces of 40 extracted human premolar teeth. The samples were divided into three exposure groups and one non-exposed control group of 10 teeth each. The specimens in the experimental groups were exposed to a radiofrequency (RF) radiation emitted from a commercial 2.4 GHz Wi Fi router (group I), LTE mobile network (group II) and a magnetic field of 3 T for 20 min (group III).The distance between the Wi-Fi router, LTE mobile network and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. Teeth samples in exposure group (group A and B) were exposed to RF for 3 days. Then the teeth were sectioned and scored for microleakage under a stereomicroscope.
