“…Gandhi and Prabhjot 16 also found a positive correlation bet ween the number of micronuclei and increasing exposure to cell phone radiation, comparing 25 users with 25 controls. Souza et al 17 did not find any correlation between micronuclei and radiofrequency exposure; however, this study reports an increase of broken eggs in the group with greater exposure. Meanwhile, the studies conducted by Hintzsche and Stopper 18 and Ros-Lior et al 19 did not find such correlation.…”

“…The other studies used DNA-specific stains, which provide added specificity to the results. Hintzsche and Stopper 18 used chromomycin A3; Ros-Lior et al 19 used DAPI; Gandhi and Prabhjot 16 and Souza et al 17 used acid-Schiff's reagent; and in this study, the Feulgen reaction was performed.…”

“…14 The oral cavity is within the area exposed to radiation emitted by cell phones. The existing reports in the literature investigating the influence of cell phone radiation on nuclear anomalies in the oral mucosa are contradictory: three of them report a positive correlation between cell phone use and genetic damage, 15,16,17 and another two indicate the absence of such correlation. 18,19 For this reason, more information on this matter is valuable.…”

The aim of this study was to evaluate the effects of exposure to cell phone electromagnetic radiation on the frequency of micronuclei, broken eggs cells, binucleated cells, and karyorrhexis in epithelial cells of the oral mucosa. The sample was composed of 60 cell phone users, who were non-smokers and non-drinkers, and had no clinically visible oral lesions. Cells were obtained from anatomical sites with the highest incidence of oral cancer: lower lip, border of the tongue, and floor of the mouth. The Feulgen reaction was used for quantification of nuclear anomalies in 1,000 cells/slide. A slightly increase in the number of micronucleated cells in the lower lip and in binucleated cells on the floor of the mouth was observed in individuals who used their phones > 60 minutes/week. The analysis also revealed an increased number of broken eggs in the tongue of individuals owning a cell phone for over eight years. Results suggest that exposure to electromagnetic waves emitted by cell phones can increase nuclear abnormalities in individuals who use a cell phone for more than 60 minutes per week and for over eight years. Based on the present findings, we suggest that exposure to electromagnetic radiation emitted by cell phones may interfere with the development of metanuclear anomalies. Therefore, it is demonstrated that, despite a significant increase in these anomalies, the radiation emitted by cell phones among frequent users is within acceptable physiological limits.

“…The risk for motor crashes significantly increased as a result of transport injuries (OR = 1.43; 95% CI = 1. 25 Among the participants with a various duration of cell phone usage, Canadians and Koreans had a higher risk for injuries to the human body compared to the other populations, although there was no statistical difference. In studies with a participant sample size ranging from 100−500 and with participants aging from 18 to 35 years, there was a higher risk for injuries.…”

Background Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. This study was designed to assess the impact of cell phone use on transport and chronic injuries.Methods Studies were systematically searched in four database and relevant reviews were searched to identify additional studies. A total of 41 studies met the inclusion criteria.Results Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.22−1.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.63−2.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.01−1.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.27−3.23), the risk of mental disease was 1.26 (95% CI: 1.17−1.35), the risk of neurological disorder was 1.16 (95% CI: 1.02−1.32), and a pooled risk of other chronic injuries, was 1.20 (95% CI: 0.98−1.59). Subgroup analyses found that motor crashes had significantly increased (OR: 1.25; 95%CI: 1.18−1.32), as well as the risk for hearing problems (OR: 4.54; 95%CI: 3.29−5.80), headaches (OR: 1.25; 95%CI: 1.18−1.32), and abnormal biochemical indicators (OR: 0.51; 95%CI: 0.04−0.99).Conclusions Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

Background: The usage of mobile phone had been increased drastically which created a major health concern among the people about the radiation emitted from mobile phones. Hence this study was aimed to evaluate the Micronuclei (MN) frequency in exfoliated oral mucosal cells in high and low mobile users based on Specific absorption rate (SAR) value.Methods: The total of 60 subjects were divided into two major groups: low SAR mobile phone users and high SAR mobile phone users. Further, Subjects who use mobile phone for more than 3 hours a week was considered as high talk time users and less than 3 hours a week was low talk time users. The buccal mucosa cells extracted by slightly scraping the oral cavity with a wooden spatula. For staining, Giemsa stain was used. Micronuclei were evaluated in 1000 cells per individual at the microscope.Results: The result show prolonged talk time may interfere with the development of micronuclei in individuals who use mobile phone for more than 3 hours per week rather than high SAR value showing a significant increase in frequency of micronuclei formation.Conclusions: The study showed mobile phone radiation had adverse effects on buccal mucosal cells.
