Abstract

Overview

In the digital era, the extensive use of mobile phones raises concerns about health risks due to radiofrequency radiation and thermal effects close to vital organs such as salivary glands, which are located near where mobile phones are commonly held.

Aim

This study aims to investigate the impact of mobile phone radiation on the volume, systolic velocity, and salivary flow rate of the parotid and submandibular glands on both the dominant and non-dominant sides of frequent mobile users.

Materials and Methods

• Study Design: Cross-sectional study.
• Sample Size: 100 individuals split evenly by gender.
• Tools Used: Ultrasonography for measurement of gland volume and Colour Doppler for systolic velocity, along with Modified Schirmer tear strips for salivary flow rates.
• Significance: Analysis via independent sample t-test.

Findings

Differences in the salivary gland parameters were noted between the dominant side (used more frequently for phone calls) and the non-dominant side:

• Higher mean volume and flow rates on the dominant side compared to the non-dominant side for both parotid and submandibular glands.
• Statistically significant differences in systolic velocity and salivary flow, suggesting potential health impacts related to chronic mobile phone use.

Conclusion

The prolonged exposure to mobile phone radiation significantly affects the biological conditions of the parotid and submandibular glands. This emphasizes the potential health risks associated with habitual mobile phone use.
