The influence of handheld mobile phones on human parotid
gland secretion
BACKGROUND: Handheld mobile phones (MPHs) have
become a -cultural’ accessory device, no less so than a
wrist watch. Nevertheless, the use of MPHs has given rise
to great concern because of possible adverse health
effects from exposure to the radiofrequency radiation
(RFR) emitted by the device. Previous studies suggested
correlation between MPH and salivary gland tumors.
OBJECTIVE: To evaluate whether MPH induces physiologic
changes in the adjacent parotid gland, located on
the dominant side, in terms of secretion rates and protein
levels in the secreted saliva.
MATERIALS AND METHOD: Stimulated parotid saliva
was collected simultaneously from both glands in 50
healthy volunteers whose MPH use was on a dominant
side of the head.
RESULTS: A significantly higher saliva secretion rate was
noticed in the dominant MPH side compared with that in
the non-dominant side. Lower total protein concentration
was obtained in the dominant compared with the
non-dominant MPH side among the right dominant MPH
users.
CONCLUSIONS: Parotid glands adjacent to handheld
MPH in use respond by elevated salivary rates and decreased
protein secretion reflecting the continuous insult
to the glands. This phenomenon should be revealed to
the worldwide population and further exploration by
means of large-scale longitudinal studies is warranted.
