Abstract

Overview

The objective of this study was to observe the effects of the duration of handheld mobile phone usage on salivary flow, salivary immunoglobulin A (IgA) level, and salivary markers for oxidative stress among students.

Materials and Methods

  • 81 students were categorized into three groups based on their duration of mobile phone usage after age- and gender-matching.
  • Groups were defined by mobile phone usage duration: less than 20 minutes per day, 20-60 minutes per day, and more than 60 minutes per day.
  • Salivary flow rate, salivary IgA level, and salivary markers for oxidative stress were evaluated.

Findings

  • Salivary flow rate showed no significant differences across the groups.
  • No significant difference was observed in salivary IgA levels.
  • Statistically significant difference was found in malondialdehyde (MDA) levels, a marker of oxidative stress, with higher levels observed in those with more extended mobile phone use.

Conclusion

While the study showed no significant effects on salivary flow rate or IgA levels, an increase in oxidative stress markers highlights potential health risks from prolonged exposure to mobile phone electromagnetic fields.
