Microleakage of amalgam restorations after exposure to electromagnetic fields from common Wi-Fi routers, LTE mobile network and 3T MRI

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.
Results: The result showed that the score of microleakage (percentage taken) was significantly higher in the exposure group I, II and III than that of control group. The scores of microleakage were not significantly different between the exposure group I and II. The scores of microleakage were significantly higher in group III as compared to other experimental groups.
Conclusion: Exposure of patients with amalgam restorations to radiofrequency radiation emitted from conventional Wi-Fi devices, mobile networks and 3T MRI can increase mercury release from amalgam restorations.
