Aim of study (acc. to author)

To investigate the oxidative stress level in saliva of cell phone users.

Background/further details

Twelve male volunteers participated in the study. Saliva samples were taken before, during (after 15 minutes) and after a 30 minutes cell phone call.

  • before exposure
  • during exposure
  • after exposure

Main outcome of study (acc. to author)

No significant differences in the examined parameters were observed before and after the cell phone call.
The authors conclude that a radiofrequency field emitted by a cell phone does not change the oxidant/antioxidant profile in the human saliva.
