Abstract

Overview

The study focuses on examining the impact of mobile phone usage duration on salivary characteristics such as flow rate, immunoglobulin A levels, and oxidative stress indicators in saliva.

Materials and Methods

  • Participants: Eighty-one students divided into three groups based on mobile phone usage duration: less than 20 minutes, 20-60 minutes, and more than 60 minutes per day.
  • Methodology: Saliva samples were examined for flow rate, immunoglobulin A levels, and markers of oxidative stress.

Findings

  • No significant effect on salivary flow rate and IgA levels across different usage durations.
  • Oxidative Stress: Notable increase in malondialdehyde (MDA) levels in heavy mobile phone users, highlighting potential oxidative stress due to prolonged exposure to radiofrequency electromagnetic waves.

Conclusion

The duration of mobile phone use is associated with an increase in oxidative stress indicators in the saliva. This signifies that heavy use of mobile phones might lead to higher oxidative stress in salivary glands exposed to electromagnetic fields, presenting a potential health risk.
