Abstract
As far as the increasing use of mobile phone as a source of non-ionizing electromagnetic radiation is concern, many side effects of this integral part of life is known on various human’s body systems and the oral cavity. Malondialdehyde and Lactate dehydrogenase are two biomarkers in saliva as oxidative stress indicators considered in this study. The existence of controversial results of many studies is another cause of this topic choice.
Unstimulated saliva sampling from 72 subjects in 3 groups with different mean time talking on the phone per day was done by spitting method. Then, the extracted saliva samples were imported to the MDA (E1371Hu) and LDH (E0747Hu) ELISA kit. Finally, the data were analysed by appropriate statistical tests. The mean concentration of MDA in group A, B and C was 22.37 11.3, 22.72 , and 21.16 . The mean LDH concentration of these 3 groups was 283.52 , 363.85 , 241.55 , respectively.The mean MDA/LDH concentration of salivary samples between the specified groups has been showed no significancy (p.value>0.05). There is no significant relationship between Salivary MDA/LDH concentrations and mobile phone talking time in 18 to 40 years-old adults. In other words, the exposure of human to cellphone radiations does not alter salivary MDA/LDH levels. However, we reported a strong relation between MDA and LDH concentration as two stress oxidative biomarkers.
