When in use, the cellular phone is situated with a proximity to the parotid gland.
Objectives: To examine whether the use of cellular phones has influence on the parotid glands regarding their saliva secretion and total protein concentration.
Methods: Stimulated parotid saliva was collected from 50 healthy volunteers (25 women, 25 men; mean age 27±3.2, range 19-33 yr) whose cellular phone use is on a dominant side of the head. All volunteers used cellular phones which do not exceed the SAR limits. Saliva collection was carried out simultaneously from both parotid glands using the Carlson Crittenden® (Lashley Cup®).
Results: A 2.54 fold increase in salivary secretion rate in the dominant side compared to the non dominant side was observed
Conclusion: A statistically different increase in secretion was found in the dominant side of cellular phone use among healthy individuals. Further research assessing cellular phone influence on the parotid gland is needed.
