Abstract

Overview

This study investigates the synergistic effects of electromagnetic fields (EMF) from common dental equipment and mobile phones on dental amalgam restorations.

Background

• Previous research highlights EMFs from devices like MRI machines and mobile phones increasing microleakage in dental amalgams.

Objective

The primary aim is to explore the impact of EMFs from both a commercial light cure dental device and a GSM mobile phone on the integrity of amalgam restorations.

Materials and Methods

• 60 non-carious human teeth were used, with Class V cavities prepared.
• Teeth were grouped and subjected to different EMF exposure conditions.
• Microleakage was assessed using a dye penetration technique under a stereomicroscope.

Findings

• Significant increases in microleakage were noted when amalgam restorations were exposed to both mobile phone radiation and light cure device EMFs.
• This increase was not only compared to the control (no exposure) but also to restorations exposed to only one of the EMF sources.

Conclusion

The findings underscore a significant health risk: EMFs from mobile phones and dental devices can collaboratively harm the integrity of dental amalgam restorations, potentially exposing patients to further dental health risks.
